Description:Crepidotus mollis (Schaeff.: Fr.) Staude
characteristics: rapid growth; aerial mycelium white, plumose, floccose; clamps absent.
Macromorphology
PiNL: advancing zone appressed to raised, hyphae hyaline. Aerial mycelium floccose to distinctly plumose, often fan-like, zonate or not, pure white, reverse white.
PDA: advancing zone appressed to raised, hyphae hyaline. Aerial mycelium felty around inoculum plug, floccose to plumose towards the margins, sometimes zonate, pure white; reverse white.
MEA: advancing zone appressed, hyphae hyaline. Aerial mycelium felty, granular to plumose, faintly zonate, sometimes with exudation droplets (water), pure white; reverse white to cream.
Micromorphology
Advancing zone of 1.5-2.5 µm wide, cylindric, straight, long hyphae; subterminal cell at times branched or with scattered small knob-like excrescences. Aerial mycelium of densely packed 1.5-3 µm wide, cylindrical, thin-walled abundantly branched hyphae, never forming a distinct plectenchymatous crust, with scattered segments with short excrescences, at times with coiled isoplerous hyphae (as fig. 25-26 in Hutchison, 1991); ampullate or slightly monilioid up to 8 µm wide segments are very rare; terminal cells erect, cylindrical, tapering or occasionally cystidia-like, 24-50 x 3-6 x 2-3 µm, lageniform, hyaline and thin-walled. Submerged mycelium densely branched, scattered with ampullate cells and often with staghornlike hyphae (see Fig. 1b) or diverticulate segments (Fig. la). Older mycelium exhibit segments which are interpreted as secundary septae.with very short, 5-10 µm long cells. Isoplerous hyphae may be observed in older cultures, too. Clamps always absent.
On a newly tested other culture medium (YPSS/2) small red bulbs were formed, which proved to be true sclerotia with an outermost layer of interlocking thick-walled hyphae.
