Memnoniella echinata

A rapidly-growing fungus that produces a blackish colony with a yellowish-brown to brownish-gray reverse, within five days, when incubated at 25oC (77oF). It is found worldwide and can be isolated from soil, dead plants, paper and textiles. It is morphologically and physiologically closely related to Stachybotrys chartarum and has cytotoxicity similar to S. chartarum. It is unknown if M. echinata produces macrocyclic trichothecenes, however, it does produce simple trichothecenes (trichodermol and trichodermin) and phenylspirodrimanes. There have not been any reports of human infections.
