Paraisaria gracilioides (Kobayasi) C.R. Li, M.Z. Fan & Z.Z. Li

Isaria gracilioides ≡ Isaria gracilioides Kobayasi

Cordyceps gracilioides = Cordyceps gracilioides Kobayasi

Ophiocordyceps gracilioides = Ophiocordyceps gracilioides (Kobayasi) G.H. Sung, J.M. Sung, Hywel-Jones & Spatafora

Paraisaria gracilioides = Paraisaria gracilioides (Kobayasi) Luangsa-ard, Mongkolsamrit & Samson, syn. nov.

Hosts.

Elateridae larvae (Shimizu 1997; Yahagi 2008).

Known distribution.

China (Anhui, Fujian), Japan, Russia (Far East) (Kobayasi 1941; Koval 1984; Liang 2007).

Notes.

The species is similar to Paraisaria gracilis (Grev.) Luangsa-ard et al., but the former grows on Coleoptera larvae ( Elateridae), while the latter on Lepidoptera larvae (Kobayasi 1941; Yahagi 2008). Hosts of the sexual C. gracilioides and its asexual Isaria gracilioides were both originally mistakenly identified as Cossidae larvae ( Lepidoptera instead of Coleoptera) (Kobayasi 1941). Fan et al. (2001) collected a sexual specimen of the species on a Coleoptera larva (wireworm); Li et al. (2004) successfully isolated its asexual morph and revised the asexual Isaria gracilioides to the asexual Paraisaria gracilioides (Kobayasi) C.R. Li et al., linked with the sexual C. gracilioides . Later, the sexual C. gracilioides has been revised in an orderly manner to O. gracilioides (Sung et al. 2007) and Paraisaria gracilioides (Kobayasi) Luangsa-ard et al. (Mongkolsamrit et al. 2019). Considering the rules of priority and one fungus, one name (Kepler et al. 2013), we combine Paraisaria gracilioides (Kobayasi) Luangsa-ard et al. with Paraisaria gracilioides (Kobayasi) C.R. Li et al.
