Assessment Notes

Taxonomic notes

Colonies on MEA (Oxoid) fast growing, attaining a diameter of 25–35 mm after 7 days at 25 °C; no or restricted growth at 37 °C, 0–10 (−20) mm. Colonies consisting of a basal felt with or without floccose aerial overgrowth, some isolates strongly floccose, white at first, becoming vinaceous; reverse mostly in shades of purple or sometimes uncolored. Conidiophores arising from submerged hyphae 4–6 μm in length, occasionally forming loose synnemata up to 2 mm high; stalks with roughened thick walls 3–4 μm wide consisting of verticillate branches with whorls of two to four phialides. Phialides 6–9 × 2.5–3 μm, having a swollen basal portion tapering into a short distinct neck about 1 μm wide. Conidia in divergent chains, ellipsoidal to fusiform, smooth-walled to slightly roughened, hyaline, purple en masse, 2–3 × 2–4 μm. Conidial structures formed near the agar atypical: phialides solitary or in verticils, 2–4, variable in length; shaped like typical Purpureocillium lilacinum phialides, or very long (up to 30 μm) and Acremonium-like. Cylindrical, occasionally slightly curved conidia formed in ‘slimy heads’ on these Acremonium-like structures, conidia on these structures variable in size, measuring 2.0–14 × 1.5–2.5 μm.
