1.8 checklist bryophytes bruxelles flandre wallonie.pdf

INTRODUCTION

The most recent publication of the Europeanchecklist of mosses (HILL et al 2006) which incor-porates substantial taxonomic changes largelybased upon recent outcomes of the molecular sys-tematics will undoubtedly influence the taxonomicpositions so far adopted in the different countriesAs Hillrsquos et al work resulted from the joint effort ofa panel of taxonomic experts reaching a consensusat a large scale remains an extremely challengingtask A good example is offered by the conflictual

treatments of difficult families such as the Potti-aceae (contrast eg ZANDER 1993 GUERRA ampCANO 2000 and WERNER et al 2005ab) Anotherissue is that the status of some of the speciesretained in the European checklist has long beencontroversial because of the strong overlap in mor-phological features and the existence of a range ofpuzzling intermediates Examples of such cases arenumerous (eg Aloina aloides and A ambiguaPlagiothecium succulentum and P nemorale Pcurvifolium and P laetum Didymodon vinealis andD insulanus Hygroamblystegium tenax and H

ABSTRACT mdash An amended checklist of the bryophytes of Belgium is presented Althoughsome taxonomic positions adopted in the most recent European checklist of mosses are dis-cussed the latter is used as a reference in an attempt to homogenize taxonomic concepts at awide scale and enable comparisons across countries Since the previous 2001 checklist of Bel-gian bryophytes a total of 17 and 14 species must be added to the Belgian bryoflora owing totaxonomic changes and floristic discoveries respectively The report of Grimmia caespiticiaat an altitude of 500-600 m is particularly noteworthy because this alpine species usuallyoccurs above 2 000 m Five additional taxa Scapania cuspiduligera Dialytrichia fragilifoliaEphemerum cohaerens Orthotrichum shawii and Tortella inclinata var densa are reportedhere as new to Belgium Six species were previously erroneously reported from Belgium andare excluded As a consequence the bryophyte flora of Belgium consists of 748 speciesincluding 5 hornworts 173 liverworts and 570 mosses whose occurrence in the three regionsof Belgium namely Flanders (5 hornworts 122 liverworts 399 mosses) Wallonia (3 horn-worts 169 liverworts 546 mosses) and Brussels-Capital Region (46 liverworts 196 mosses)is documented Thirty-six species (6 liverworts and 30 mosses) have not been recorded since1980 and are most probably extinct The new checklist is used to update the list of Europeanred list species that are present in Belgium which now includes 49 species

varium Tortella bambergeri and T tortuosaOrthotrichum schimperi and O pumilum) Whilethe genetic bases for justifying species recognitionis lacking in most cases it is clear that some of thesespecies form complexes of polyphyletic origin(SHAW amp ALLEN 2000 VANDERPOORTEN et al 2004)and convergent morphology (VANDERPOORTEN ampJACQUEMART 2004) In such cases the conflictinginterpretations of taxonomists will still lead to sub-stantial differences in diversity assessments andhence difficulties of comparisons across- (and evenwithin-) countries Thus although Hillrsquos et al refer-ence list should arguably serve as a reference basisto homogenize taxonomic concepts between coun-tries departures from the proposed list will still per-sist in the checklist adopted within each country InThe Netherlands for example (SIEBEL et al 2005)most of the above species have been synonymized

In this paper we discuss the application ofthe new European checklist to the Belgian bry-oflora While preparing this revision it alsoappeared that to be useful to a broad panel ofusers including local florists taxonomists seekingcomparative data at a national or regional scaleand conservation agencies the checklist shouldnot only provide a taxonomic and nomenclaturalreference basis for the Belgian bryoflora but alsoinclude information about species occurrence atthe regional level and threats Our motivation forpresenting an updated checklist since our previ-ous contribution (SOTIAUX amp VANDERPOORTEN

2001) was further stimulated by a number ofadditional species reports and the important con-

sequences for the European red list species pres-ent in Belgium (ECCB 1995)

METHODS

For liverworts and hornworts nomenclature fol-lows GROLLE amp LONG (2000) with some modificationsdue to subsequent taxonomic and nomenclatural worksincluding GROLLE amp SO (2003) for Metzgeria andSZWEYKOWSKI et al (2005) for Conocephalum Fol-lowing DE ROO et al (2007) ENGEL amp BRAGGINS

(2005) are not followed in accommodating Myliaanomala within its own genus Leiomylia GROLLE ampLONG (2000) who treat Lophocolea and Chiloscyphusas separate genera are also followed There is how-ever growing evidence from molecular studies (egHENTSCHEL et al 2006) that ENGEL amp SCHUSTER (1984)were right in merging Lophocolea with Chiloscyphus

For mosses the European checklist of HILL et al(2006) served as a reference Therefore HILL et al(2006) are followed in merging a series of species (egBryum barnesii and B dichotomum) even though theydisplay at least in Belgium a clear morphological dis-continuity and might deserve a distinct taxonomic statusFor the same reasons HILL et al (2006) are followed inrecognizing a series of morphologically extremely simi-lar and intergrading species (see above) although webelieve that such species because of the difficulty intheir identification add lsquonoisersquo to floristic inventoriesand hence that a more conservative strategy would be toreduce these species to synonymy In the case of Leuco-bryum however HILL et al (2006) are not followed inrecognizing three species in the European flora for rea-sons detailed in the text Nomenclatural changes sincethe 2001 checklist are summarized in Table 1

RESULTS

CHANGES WITH THE PREVIOUS CHECKLIST

New taxa

Fourteen species are reported as new sincethe 2001 checklist Haplomitrium hookeri (SOTI-AUX et al 2006) Scapania calcicola (SOTIAUX etal 2002) S cuspiduligera (see below) Bryum dyf-frynense (DE BEER amp MARTENS 2007) Dialytrichiafragilifolia (see below) Ephemerum cohaerens(see below) Grimmia caespiticia (MUNtildeOZ ampPANDO 2000) G dissimulata (DE BEER 2007) G elongata (GREVEN amp SOTIAUX 2003) Isothe-cium holtii (cited in SIEBEL amp DURING 2006 for the Ardennes district based on Siebel 01381Robertville Warche Valley IFBL G834237082001 BR and herb Siebel) Orthotrichumshawii (see below) Polytrichastrum alpinum(REINEKE et al 2002) Rhytidiadelphus subpinna-tus (SCHUMACKER amp SOTIAUX 2003) and Tortulamucronifolia (SOTIAUX amp SOTIAUX 2005)

Grimmia caespiticia (Brid) Jur was oncecollected in Belgium at the beginning of the 20th

century (Cornet 1906 NY) (MUNtildeOZ amp PANDO

2000) The collection includes two fertile plantswith exserted capsules and an obliquely rostrateoperculum The leaves are distinctly longitudinallyfurrowed Hence the specimen perfectly matchesthe circumscription of G caespiticia The Belgianlocality at an altitude of 500-600 m is completelyoutside the altitudinal range of this alpine specieswhich mostly occurs at an altitude of 2 000 m orhigher with a few occurrences reported down toan altitude of 1 400 m (GREVEN 1995)

A total of 17 species must be added to thechecklist due to the creation or erection at thespecies level of former infraspecific taxa alreadyknown from Belgium These species includeConocephalum salebrosum Aloina ambiguaAnomobryum concinnatum Bryum kunzeiCampylium protensum Dichodontium flavescensDidymodon insulanus Ephemerum minutissi-mum Heterocladium flaccidum Orthotrichumschimperi Palustriella falcata Plagiotheciumsucculentum Polytrichum uliginosum Syntrichiacalcicola Tortella bambergeri Tortula schim-peri and Zygodon stirtonii

Rediscovered taxa

Two species considered extinct have beenrediscovered

Philonotis marchica had not been seen inBelgium since 1912 (RAEYMAEKERS 1981) but



was discovered in a wetland restoration area nearBruges (STIEPERAERE 2007)

Pterygoneurum lamellatum was found in2005 very close to the Dutch and German borderin Bassenge (ANDRIESSEN et al 2006) The previ-ous collection of the species dated back to morethan 100 years ago

Excluded taxa

Three species must be deleted from the pre-vious checklist as a result of the reduction to syn-onymy in HILL et al (2006) These speciesinclude Bryum barnesii (=B dichotomum) Brutilans (=B pallens) and B versicolor (=Bdichotomum) A fourth species Leucobryumjuniperoideum is also deleted Contra FRAHM

(2005) which is the reference cited by HILL et al(2006) for keeping L juniperoideum L albidumis by no means characterized by leaves that areless than 2 mm long (2-4 mm for examplereported by CRUM amp ANDERSON 1981) Leuco-bryum albidum does intergrade morphologicallywith L glaucum the latter including in its rangethe poorly defined L juniperoideum Leucobryumjuniperoideum was therefore synonymized and itwas proposed that the European Leucobryumflora consists of only two species L glaucum andL albidum (VANDERPOORTEN et al 2003) Onlythe former has to date been found in BelgiumAlthough L albidum exhibits a more southwest-ern distribution than L glaucum it was found inFrance and Germany so that the species is verylikely to occur in Belgium as well

Seven additional species are excluded for thereasons detailed below

Scapania praetervisa The occurrence of thisboreal calcicolous species on highly acidic soilswith Calluna vulgaris and other strictly aci-dophilous species such as Lophozia grandiretis(DE ZUTTERE amp POHL 1991) at low elevation isecologically unlikely The presence of pinkishgemmae used as evidence for the identity of thecollection with S praetervisa (DE ZUTTERE ampPOHL 1991) can be observed in S scandica anacidophilous species present in the Ardennes Thematerial of S praetervisa is unfortunatelyunavailable for re-examination and the species is

therefore tentatively excluded from the Belgianchecklist

Fissidens curnovii (=F bryoides var caespi-tans) All the specimens attributed to this taxonfrom Belgium were re-examined by M A Brug-geman and proved to belong to F bryoides varbryoides

Fissidens limbatus (= F crispus) No collec-tion of this Mediterranean species was found at BRor LG and the record most probably resulted froma synonymy error in SCHUMACKER et al (1985)

Grimmia reflexidens Muumlll Hal was reportedfrom Belgium from the same locality as G cae-spiticia in Spa Promenade Annette et Lubin(MUNtildeOZ amp PANDO 2000) The collection of Greflexidens (Cornet 1906 BP) is sterile and thegametophyte does not match that of the typicalexpression of the species MUNtildeOZ amp PANDO

(2000) indicated that the group of species includ-ing G australis (Dixon amp Sainsbury) J Muntildeoz ampOchyra G alpestris (F Weber amp D Mohr) Schle-ich and G reflexidens is characterized bybulging laminal cells in leaf cross-section butemphasized that this character cannot be observedon poor specimens Pending convincing evidenceof the presence of G reflexidens in Belgiumbased on fertile material we exclude this alpinespecies from the checklist

Grimmia mollis Bruch amp Schimp reportedfrom Belgium (MUNtildeOZ amp PANDO 2000) was ten-tatively not included in the previous checklist ofbryophytes of Belgium pending further evidenceof the presence of this alpine species in Belgium(SOTIAUX amp VANDERPOORTEN 2001) J Muntildeoz(pers comm) confirmed that the report of Gmollis in Belgium was a mistake

Meesia longiseta DE SLOOVER (1970)renamed the original collection as Aulacomniumpalustre A later collection at BR from Trochrsquosherbarium is of doubtful origin and probably afraud

Meesia uliginosa KICKX (1867) reportedfragments of this species from a supply of Sphag-num for the Botanic Garden of Ghent harvestednear Damme in 1857 DE SLOOVER (1970)showed that the specimen in BR with a label inTrochrsquos handwriting (Damme Kickx 1850) isprobably a fraud We found that the collection is



mixed with Blepharostoma trichophyllum and hasmica fragments in the peaty substrate This makesit extremely unlikely that the specimen comesfrom anywhere near Damme

Taxa considered as extinct

Catoscopium nigritum This species wastreated as extinct in our previous checklist Evi-dence for its presence in Belgium remains how-ever subject to controversy There has been norecord of this species from Flanders since DE

SLOOVER (1970) re-identified the original speci-men cited in DELOGNE (1883) as Dicranella variaand showed that a second correctly named speci-men in BR from the Troch collection is mostprobably a fraud In the herbarium of the CarnoyInstitute (LV transferred to BR in 1999) wefound another specimen of C nigritum Thespecies name and the collectorrsquos name are in De-lognersquos handwriting the locality ldquoEntre Ostendeamp Blanckenbergherdquo is a later addition in a differ-ent handwriting Therefore some doubts remainregarding this record Most recently a collectionmade by Castagne in 1956 from Baraque Michelin the Ardennes was found in the Parent herbar-ium (DE ZUTTERE amp SOTIAUX 2007) In the com-plete absence of basic fens around BaraqueMichel however a little doubt also persistsregarding the validity of this record

THE CHECKLIST

As a consequence of the changes exposedabove the bryophyte flora of Belgium (30528km2) consists of 748 species including 5 horn-worts 173 liverworts and 570 mosses (Appen-dix) A total of 526 species is recorded to datefrom Flanders (13522 km2) including 5 horn-worts 122 liverworts and 399 mosses The Brus-sels-Capital Region (162 km2) bryophyte flora iscomposed of 242 species including 46 liverwortsand 196 mosses In Wallonia (16844 km2) 718species have been recorded to date including 3hornworts 169 liverworts and 546 mosses(Appendix)

Thirty-six species including 6 liverwortsand 30 mosses have not been recorded since1980 and are probably extinct

CONSEQUENCES FOR THE EUROPEAN RED LIST

SPECIES OF BELGIUM

Thirty-six European red-list species werelisted as occurring in Belgium (ECCB 1995)[excluding Didymodon glaucus only reportedfrom the Grand-Duchy of Luxembourg which issubject to a separate survey (WERNER 2003)]Four species Fossombronia incurva Grimmialisae Hamatocaulis vernicosus and Rhynchoste-gium rotundifolium which do occur in Belgiumwere omitted from the 1995 ECCB list Since thepublication of the European red list twelve addi-tional red list species have been reported fromBelgium Anthoceros caucasicus (HEYLEN et al2001) Haplomitrium hookeri (SOTIAUX et al2006) Ephemerum stellatum (VANDERPOORTEN etal 1996) Orthotrichum consimile (SOTIAUX et al1998a) O ibericum (HEYLEN amp WALRAEVENS

2001) O rogeri (SOTIAUX amp SOTIAUX 2002) Oscanicum (SOTIAUX et al 1998b) Schistidiumhelveticum (BLOM 1996) S papillosum (BLOM

1996) S pruinosum (BLOM 1996) and Ulotarehmannii (SOTIAUX amp SOTIAUX 1999) Two addi-tional species Ephemerum cohaerens and Grim-mia caespiticia are reported here FurthermoreAneura maxima was found new to Europe in Bel-gium (ANDRIESSEN et al 1995) We have sinceobserved the species fairly frequently in the Bel-gian and French parts of the Ardennes where itgrows in deep seeps often with ChrysospleniumIt seems to be an overlooked species that mayhave been confounded with Pellia neesiana andP epiphylla At the European scale howeverAneura maxima is only reported from 1-2 locali-ties in France Luxembourg Poland and Finland(VANDERPOORTEN et al 2006) As a consequencewe suggest with WERNER (2003) that the speciesshould be included within the European red listbut with the status lsquoinsufficiently knownrsquo as itsexact distribution in Europe remains to be docu-mented (VANDERPOORTEN et al 2006) Lastly fivespecies must be deleted from the European redlist species of Belgium Buxbaumia viridis (DE

SLOOVER amp STIEPERAERE 1999) and Fissidensovatifolius were erroneously listed from Belgiumin the treatment of ECCB (1995) Meesialongiseta must be excluded from the checklist of



Belgium for reasons detailed above while Bryumstirtonii B versicolor and Rhynchostegiellajacquinii are currently considered to be conspe-cific with Bryum elegans B dichotomum and Rteneriffae respectively

As a consequence 49 species listed in theEuropean red list (ECCB 1995) occur in Belgium(Table 2) Seven species are probably extinct in

Belgium and all the others are known from one tofew localities except Aneura maxima (VANDER-POORTEN et al 2006) Cleistocarpidium palustreand Orthotrichum consimile (SOTIAUX et al1998a SOTIAUX amp VANDERPOORTEN 2004) forwhich the Belgian populations play a significantrole in the conservation of those species inEurope

varium Tortella bambergeri and T tortuosaOrthotrichum schimperi and O pumilum) Whilethe genetic bases for justifying species recognitionis lacking in most cases it is clear that some of thesespecies form complexes of polyphyletic origin(SHAW amp ALLEN 2000 VANDERPOORTEN et al 2004)and convergent morphology (VANDERPOORTEN ampJACQUEMART 2004) In such cases the conflictinginterpretations of taxonomists will still lead to sub-stantial differences in diversity assessments andhence difficulties of comparisons across- (and evenwithin-) countries Thus although Hillrsquos et al refer-ence list should arguably serve as a reference basisto homogenize taxonomic concepts between coun-tries departures from the proposed list will still per-sist in the checklist adopted within each country InThe Netherlands for example (SIEBEL et al 2005)most of the above species have been synonymized

In this paper we discuss the application ofthe new European checklist to the Belgian bry-oflora While preparing this revision it alsoappeared that to be useful to a broad panel ofusers including local florists taxonomists seekingcomparative data at a national or regional scaleand conservation agencies the checklist shouldnot only provide a taxonomic and nomenclaturalreference basis for the Belgian bryoflora but alsoinclude information about species occurrence atthe regional level and threats Our motivation forpresenting an updated checklist since our previ-ous contribution (SOTIAUX amp VANDERPOORTEN

2001) was further stimulated by a number ofadditional species reports and the important con-

sequences for the European red list species pres-ent in Belgium (ECCB 1995)

METHODS

For liverworts and hornworts nomenclature fol-lows GROLLE amp LONG (2000) with some modificationsdue to subsequent taxonomic and nomenclatural worksincluding GROLLE amp SO (2003) for Metzgeria andSZWEYKOWSKI et al (2005) for Conocephalum Fol-lowing DE ROO et al (2007) ENGEL amp BRAGGINS

(2005) are not followed in accommodating Myliaanomala within its own genus Leiomylia GROLLE ampLONG (2000) who treat Lophocolea and Chiloscyphusas separate genera are also followed There is how-ever growing evidence from molecular studies (egHENTSCHEL et al 2006) that ENGEL amp SCHUSTER (1984)were right in merging Lophocolea with Chiloscyphus

For mosses the European checklist of HILL et al(2006) served as a reference Therefore HILL et al(2006) are followed in merging a series of species (egBryum barnesii and B dichotomum) even though theydisplay at least in Belgium a clear morphological dis-continuity and might deserve a distinct taxonomic statusFor the same reasons HILL et al (2006) are followed inrecognizing a series of morphologically extremely simi-lar and intergrading species (see above) although webelieve that such species because of the difficulty intheir identification add lsquonoisersquo to floristic inventoriesand hence that a more conservative strategy would be toreduce these species to synonymy In the case of Leuco-bryum however HILL et al (2006) are not followed inrecognizing three species in the European flora for rea-sons detailed in the text Nomenclatural changes sincethe 2001 checklist are summarized in Table 1
