Aspergillus navahoensis explained

Aspergillus navahoensis is a species of fungus in the genus Aspergillus. It is from the Nidulantes section.^[1] The species was first described in 1982.^[2] It was isolated from sand in Arizona, United States.^[1] It has been reported to produce averufin, norsolorinic acid, 6,7,8-trihydroxy-3-methylisocoumarin,^[3] desferritriacetylfusigen, echinocandin B,^[4] and sterigmatocystin.^[5]

Growth and morphology

A. navahoensis has been cultivated on both Czapek yeast extract agar (CYA) plates and Malt Extract Agar Oxoid® (MEAOX) plates. The growth morphology of the colonies can be seen in the pictures below.
