provided by Cybertruffle
On Potato Sucrose Agar (PSA). Colonies. After 4 days growth varies from 5.25-5.8 cm diam., with a mean ñ SD = 5.53 ñ 0.39; aerial mycelium white to pale violet with grayish violet pigmentation. On Potato Dextrose Agar (PDA). Colonies. After 10 days growth varies from 8.5-8.95 cm length, with a mean ñ SD = 8.73 ñ 0.32; aerial mycelium white to pastel violet, with grayish violet pigmentation; mycelium producing hyphal swellings, but not "chlamydospores". Conidia. Of two types; macroconidia rarely formed, fusoid, 20-50 × 2.5-4 μm, 3- to 5-septate, each with a tapering apical cell and poorly developed basal cell; microconidia obovoid to clavate, 10-15 × 1.5-2.5 μm, 0-septate, formed in false heads and chains of short to medium length on mono- and polyphialidic conidiogenous cells. Teleomorph. Not known. Notes. This species grows on Glycerol Nitrate Agar (G25N), producing white or pale orange aerial mycelium and yellow pigmentation; growth on mannitol sucrose medium results in white aerial mycelium and pale red pigmentation; growth on Czapek-Dox Iprodione Dichloran Agar (CZID) exceeds 5 cm diam. with white to reddish grey aerial mycelium and grayish magenta pigmentation.
