Characteristics: Growth/Culture Notes on Spore Trap Recognition Notes on Tape Lift Recognition
Grows well on general fungal media; most isolates need "light/dark cycling" for sporulation. Colonies are shades of gray to brown. Distinctive; large second or center cell gives conidia pronounced curved shape. Conidia from species with less pronounced curve may be misidentified. Some Drechslera spores are similar. Distinctive, readily identifiable on tape lifts.
