|Characteristics: Growth/Culture||Notes on Spore Trap Recognition||Notes on Tape Lift Recognition|
|Grows well on all general fungal media. Colony spreads easily over the surface of the petri dish. May form black sclerotia.||Fairly distinctive, frequently with a visible inner cell wall, and an attachment point at one end. Spores are slightly pigmented.||Distinctive, especially if spore bearing structures are present.|
