the genus "acremonium" is a large polyphyletic genus of approximately 150 species, many of which are derived from a closely related families in the "sordariomycetes". the genus includes many slow growing, simply structured, anamorphic filamentous fungi, typically encountered in wet, cellulose-based building materials suffering form chronic wet conditions. characteristic morphology in this genus is septate hyphae giving rise to thin, tapered aculeate phialides that are usually unicellular, or weakly branched conidiophores. human infections, though rare, usually occur in severely immunodeficient individuals. "a. strictum" is mostly known to be involved with myparasitic relationships, as well as being a plant parasite and endophyte.
