Species (sample #1) :Geotrichum fici

Where: from bread (initially green-grey fungi which grow beside white colony)

How collected and isolated: Transferred from food into plate, #1 growth into white fungi but still have small green colony in the middle of plate (Fig3 up). 2nd subculture gave the colony same white so the green one probably the contamination (Fig6 down)Evidence:

Characteristics:White soft fluffy colony with radial-like edge (Fig6 (26d), Fig7(up 35d, down 20d)). Fig1, 2, 4, 5 are permanent slides with conidia forming as unequal-shaped arthrospores developed from segmentation (Fig2&4). Have a pineapple (fruit) smelling at begin and yogurt like smelling after 1 month (G. fici)

Young conidia around the margins are often blue green. Will produce readily break conidia (like powder) which easily loose when jarred. Produce yellow to brown soluble pigment. Flat colony.
