Notes: 

The type species of Mariannaea is M. elegans (Corda) Samson and it is a member of Nectriaceae in a recent phylogenetic study. The taxonomic revision of M. pruinosa is necessary to reflect its phylogenetic placement in Cordycipitaceae.

Commentary: 

Cordyceps pruinosa can be easily identified using its host affiliation being a pathogen of Limacodid pupa (Lepidoptera). It is restricted to Asia and frequently found in geographically distant countries (e.g., China, Japan, Sri Lanka, Thailand). However, In the description of Kobayasi (Kobayasi, 1941), this species was recorded to have a filiform ascospores that are disarticulated into partspores. However, the observation for the species

 

lectotypication is necessary.
