Soil fungi include "Aspergillus" and "Penicillium" which predominantly produce ferrichromes. Fungal pericarditis is usually due to histoplasmosis, or in immunocompromised hosts Aspergillus, Candida, and Coccidioides. The fungus Aspergillus fumigatus effectively degrades plasticized PVC. Other significant fungal allergens include aspergillus and alternaria-penicillin families. Aflatoxins are potent carcinogenic chemicals produced by molds such as "Aspergillus flavus" and "Aspergillus parasiticus". Prominent and important genera of filamentous ascomycetes include "Aspergillus", "Penicillium", "Fusarium", and "Claviceps". The enzyme quercitrinase can be found in "Aspergillus flavus". C. All are produced by "Penicillium" and "Aspergillus" species. The lifecycle of filamentous fungi including "Aspergillus" spp. Caspofungin has been effective in treating fungal infections caused by "Aspergillus" and "Candida" species. Other fungi demonstrated to cause endocarditis are "Histoplasma capsulatum" and Aspergillus. Aspergillus sojae is a species of fungus in the genus "Aspergillus". Aspergillus tamarii is a species of fungus in the genus "Aspergillus". Aspergillus parasiticus is a fungus belonging to the genus "Aspergillus". By definition, it is caused by fungi of the genus "Aspergillus".
