Cordyceps rosea Kobayasi & Shimizu, Bull. natn. Sci. Mus., Tokyo, B 8(4): 112 (1982)

Index Fungorum number: IF 114258, Facesoffungi number: FoF07467

Parasitic on Lepidoptera larva or pupa. Sexual morph: Stroma arising from insect body, stipitate, multiple or single, flexuous or straight, orange, fleshy, unbranched. Perithecia 329–846 × 343–667 (x̄ = 555 × 486, n = 20) μm, superficial, born on upper region of stroma, ovoid. Peridium 22–49 (x̄ = 34, n = 20) μm wide, membranous, comprised of yellow, thick-walled cells of textura angularis. Asci 212–595 × 2.5–5.5 (x̄ = 395 × 4, n = 30) μm, 8-spored, unitunicate, narrowly cylindrical, with round, attenuate base and thickened, hemispherical cap. Ascospores 2–5.5 × 0.7–1.5 (x̄ = 3 × 1, n = 100) μm, filiform, hyaline, disarticulating into secondary spores and spraying from perithecia when mature. Secondary ascospores cylindrical, hyaline, smooth-walled, aseptate, truncated at both ends, straight, occasionally swollen spores present. Asexual morph: Undetermined. (Adopted from Hyde et al. 2020)

Culture characteristics: colonies growing on PDA, circular, slightly raised, edge entire, velvety, reaching 18 mm in 16 days at 25 °C, white to pale yellow in PDA medium (Hyde et al. 2020).

Known hosts and distribution: Lepidopteran pupae and larvae (Taiwan and Yunnan Province, China) (Hyde et al. 2020).

Sequence data: AMS10 (ITS = MT012346, LSU= MT012353, SSU = MT012360, TEF = MT025052). Phylogenetic tree (see entry Cordyceps pruinosa) (Hyde et al. 2020).
