Species/Subspecies: Sarocladium strictum
Categories: Human pathogen; plant pathogen; of practical use
Etymology: Genus name: branched goblet (?!?).
Species epithet: sharply demarcated.
Alternative Species Name(s):Acremonium strictum
Significance:  [Unclassified]   
Macromorphology (smell):
Sarocladium strictum 
Colonies grow rapidly at 30°C on glucose-pepton agar and reach a diameter of 5 cm within a week. Colonies are flat, with a smooth, moisty, velvety or floccose texture, which may resemble thin patches of cotton.
Sarocladium strictum
S. strictum has long slender phialid cells. The conidia (3.3-5.5 x 0.9-1.8 µm) are cylindrical or elliptical and are formed in bundles at the tips of the phialid cells.
Spec. Char.:
Reservoir: S. strictum, like many other fungi, is a saprotrophic species, occurring in soil, on plant debris and on decaying macroscopic fungi (mushrooms).
Hosts/substrateDisease/effectClinical picture or result
Mono- and dicotyledonous crops.Stalk rotThe leaves dry on one side of the midrib of these plants, causing the plant to wilt and get discolored vessels on the stem near the soil line.
Immunocompromised humansDisseminated infectionsPneumonia, osteomyelitis, endokarditis, meningitis and sepsis.
Immunocompetent humansLocal infectionsOnychomycosis, otomycosis and burn wound infections

Taxonomy/phylogeny: S. strictum is devided into three genogroups: I, II and III.
Practical use:S. strictum can be used for biological control of Helminthosporium solani, which is a fungus that attacks potatoes and causes large economic losses in, among other countries, USA.

S. strictum produces some types of cephalosporins.
