Species of fungus From Wikipedia, the free encyclopedia
Penicillium crustosum is a blue-green or blue-grey mold that can cause food spoilage, particularly of protein-rich foods such as meats and cheeses. It is identified by its complex biseriate conidiophores on which phialides produce asexual spores. It can grow at fairly low temperatures (it is a psychrophile), and in low water activity environments.[2]

Penicillium crustosum produces mycotoxins, most notoriously the neurotoxic penitrems, including the best known penitrem toxin, penitrem A,[3] and including penitrems A through G. Penitrem G has been shown to have insecticidal activity.[4] In addition, P. crustosum can produce thomitrems A and E, and roquefortine C.[5] Consumption of foods spoiled by this mold can cause transient neurological symptoms such as tremors.[6] In dogs, symptoms can include vomiting, convulsion, tremors, ataxia, and tachycardia.[7]
