Paradingleyomyces Y. Wang tris & T. C. Wen gen. nov.

Etymology.

Morphologically resembling the genus Dingleyomyces .

Type species.

Paradingleyomyces lepidopterorum Y. Wang tris & T. C. Wen , sp. nov.

Description.

Parasitic on Ophiocordyceps cf. cochlidiicola . Sexual morph: Stroma absent. Perithecia forming from white subiculum covering stromata of Ophiocordyceps cf. cochlidiicola , superficial, scattered, brown, ovoid or ellipsoidal. Asci cylindrical with a thickened cap, attenuated toward the base. Ascospores filiform, hyaline, disarticulating into many cylindrical secondary ascospores at maturity. Secondary ascospores cylindrical, aseptate, smooth-walled, with truncated ends. Asexual morph: Undetermined.

Notes.

Both Paradingleyomyces and Dingleyomyces are monotypic genera and s hare similar morphological characteristics, including the formation of superficial perithecia on a white subiculum, cylindrical asci with thickened caps, and filiform ascospores that disarticulate into cylindrical secondary ascospores. Additionally, the type species of both genera occur as hyperparasites on Ophiocordyceps species ( Johnston and Park 2023). However, multigene phylogenetic analysis revealed that these two genera exhibit a paraphyletic relationship, indicating they are not congeneric. Paradingleyomyces can be easily distinguished from Perennicordyceps by its reduced stromata, whereas Perennicordyceps features cylindrical to clavate, branched stromata with prominent rhizomorphs immersed in the substrate, and perithecia forming from the middle to upper parts of the stromata ( Ban et al. 2009; Xiao et al. 2019, 2023).
