Basionym: Isaria atypicola Yasuda, 1914
Synonyms:Spicaria (Isaria) atypicola (Yasuda) Petch Trans. Br. Mycol. Soc. 23: 140. 1939. Isaria pachylomera Kawamura - Jap. J. Bot. 4: 229. 1929. Spicaria velutiformis Petch - Trans. Br. Mycol. Soc. 16: 238. 1932.
Teleomorph state: Cordyceps cylindrica Petch
Description:Host covered with dense weft of pink mycelia, showing a velvety appearance. In early stages the mycelia coming out of the joints in the legs and body eventually fully covered with layers of conidiophores. Hyphae and conidiogenous structures smooth-walled, same as in pure culture. Colonies on PDA relatively fast-growing, attaining a diam. of 40 mm within 14 d at 25°C. Colonies at first white becoming pink with age due to conidiation. Reverse cream to yellow. Conidiogenous cells arranged in dense clusters or in whorls. Phialides mostly without neck and almost cylindrical. Conidia cylindrical, pink to purple, in dry divergent chains. The first link of Nomuraea atypicola with Cordyceps cylindrica was reported by Evans (1982) and more detailed notes on the link between Nomuraea atypicola and Cordyceps cylindrica was noted by Evans and Samson (1987). In Thailand the link between the anamorph and teleomorph was reported by Hywel-Jones and Sivichai in 1995.
