What is Acremonium

Acremonium species are usually slow growing and are initially compact and moist. This genus is distinguished from hyaline isolates of Phialophora by the absence or very limited development of a collarette on the phialide and the predominant formation of well differentiated, awl-shaped phialides with a basal septum. Microconidial Fusarium isolates may be confused with Acremonium, but they usually grow faster and have colonies with a characteristic fluffy appearance. The information provided here may not always apply precisely to an individual patient's situation.

Acremonium is a genus of Fungi in the Hypocreaceae family; it was previously known as "Cephalosporium".  The genus Acremonium currently contains approximately 100 species, of which most are saprophytic, being isolated from dead plant material and soil. Their conidia are usually one-celled (i.e. ameroconidia), hyaline or pigmented, globose to cylindrical, and mostly aggregated in slimy heads at the apex of each phialide. Acremonium is potentially toxic if ingested. Individuals who are allergic to this fungus can experience nausea, vomiting and diarrhea. It can cause nail infections, corneal ulcers, endocarditis, and meningitis.
Acremonium hyphae are fine and hyaline and produce mostly simple phialides. These mycotoxins and variants are a carcinogen, having the ability to destroy the immune system, internal organs, bone marrow and brain. It is commonly encountered in wet, cellulose-based building materials. Colonies can mature in less than a week in a warm, moist environment, making Acremonium a very fast growing fungus.
