Synonym: Isaria carnea.
Chromelosporium carneum is a species of fungus in the Ascomycota phylum. It is characterized by its pink to reddish-brown colonies and production of ellipsoidal conidia. In East and Central Texas, Chromelosporium carneum has been found in soil and on decaying organic matter, often associated with grasslands and open woodlands. It typically fruits in the spring and summer months, producing small, sessile ascomata that contain cylindrical asci with 8-spored ascospores. The fungus is relatively rare in the region, but can be encountered in areas with rich soil and high levels of organic matter.
