A Penicillium known for producing mycophenolic acid (Wang et al. 2026) that has been recorded as a contaminant of cultivated mushrooms. In Korea it caused green mould on beech mushroom (Hypsizygus marmoreus): it disrupted mycelial regrowth after scraping and interfered with pinhead formation, in the first report of this disease (Kim et al. 2020). Papers cited by Wang et al. (2026) also report it causing blue mould on Grifola frondosa and Pleurotus ostreatus. It is a sensitising species with a documented allergen (INSPQ).
Not edible; a contaminant. A sensitising species with a documented allergen, Pen b 26 (INSPQ). It is a known producer of mycophenolic acid (Wang et al. 2026). Building isolates have been tested for toxin-induced lung inflammation in mice (INSPQ).
