Species of Acremonium are recognized by solitary to weakly branched, tapering phialides arising from vegetative filaments and bearing a wet cluster of mostly 1-celled spores (conidia). The filaments are sometimes bound together into "ropes" several cells in diameter. Compare with Verticillium, Sporothrix, and Phialophora. Common in soil, plant debris, rotting mushrooms, etc. Some appear to be parasitic on living fungi. Holomorphs: Cordyceps, Emericellopsis, Hapsidospora, Leucosphaerina, Nectria, and many others.
