History and taxonomy

 * originally discovered as Isaria sulfurea by Fiedler
 * transferred from Isaria to Chrysosporium by Oorschot & Samson, who originally thought its teleomorph family was ascophaeraceae

Growth, morphology and physiology

 * filamentous, found to have wide hyphae (~ 4µm) when lacking fruiting bodies
 * conidia are pale-yellow in colour
 * conidia in the form of singular enlarged cells, with homogeneous walls not made of hyphae or cells
 * conidia mature semi-synchronously terminally and laterally relative to hyphae, approximately 2-8 per conidogenous cell
 * able to grow on media with low or high concentrations of sugar or salt
 * grows in temperatures between 5°C-30°C, optimally at 25°C
 * although it produces some keratinase, it is not keratinolytic

Habitat and ecology

 * considered a dermatophyte-like keratinophilic fungus
 * Has been found on cow claws
 * Also been discovered on human hair and nails
 * suggested to grow on calcium-rich, fatty materials
 * this is exemplified as well due to its growth on cheese
 * can be found on cheese rinds of aged cheese in natural caves of Auvergne and Pyrenees, France
 * French consider the presence of the fungi to be a good sign of cheese aging, calling it fleur jaune, meaning yellow flower
