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.
I suggest including it in the list of least concern (LC).
According to GBIF the species has 518 occurrences, distributed worldwide.
There are 518 occurrences in the world, with the highest number of records in Australia.
isolated in various habitats, including cultivated and uncultivated soils, forests, meadows, deserts, in leaves as endophytes, etc.
Although widely distributed, the species is found in areas that suffer anthropogenic action.
