Type: Simplicillium_ lanosoniveum (J.F.H. Beyma) Zare & W. Gams. Description: Hyperparasitic on rusts or parasitic on nematodes or occurring in soil. Asexual morph: Mycelium thin, hyaline, septate, branched, smooth-walled. Phialides arising from prostrate aerial hyphae or rope-like and flask-shaped synnemata, typically solitary, rarely in whorls of 2–3, gradually tapering towards the apex, elongate, slender, smooth-walled, phialidic. Conidia hyaline, oval, spindle-shaped, cylindrical, subglobose to ellipsoidal, fusoid to filiform, straight to curved, smooth-walled. Conidia commonly form in small globose heads, sometimes in branched, unbranched, zigzag or imbricate chains, occasionally in sympodial proliferation with cylindrical conidium-bearing denticles. Colonies of species in this genus are usually fast growing, reaching 10–38 mm within 10 days on PDA, white, reverse brownish-cream to pale yellow, margin entire, cottony, fluffy or floccose. Some species produce yellow or orange pigment. Crystals are commonly present in the agar. Sexual morph: Torrubiella.
