Neocochlearomyces

Neocochlearomyces Pinruan, Sommai, Suetrong, J.Z. Groenew. & Crous, in Crous et al., Persoonia 41: 381 (2018)

 Index Fungorum number: IF 828085; Facesoffungi number: FoF 08095, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.

Saprobic on leaves. Sexual morph: Unknown. Asexual morph: Mycelium partly superficial and partly immersed, pale brown, smooth. Conidiophores solitary, macronematous, mononematous, sub cylindrical, septate, erect, straight, brown, smooth, thick-walled, with basal rhizoids; stalk forming an apical fanlike conidiogenous region consisting of radiating brown, warty, septate, tightly aggregated cylindrical arms, with acute terminal cells. Conidiogenous cells terminal and intercalary on the one side of the swollen fan-like structure; loci inconspicuous, phialidic. Conidia falcate, aseptate, equilateral, with convex and flat plane, both ends obtuse to sub obtusely rounded, hyaline, smooth-walled, guttulate, with a single, filiform, unbranched setula at each end on the inner straight plane, forming a slimy spore mass (Adapted from Crous et al. 2018).

 

Type species: Neocochlearomyces chromolaenae Pinruan, Sommai, Suetrong, J.Z. Groenew. & Crous

 

Notes: Neocochlearomyces was introduced by Pinruan et al. in Crous et al. (2018) with N. chromolaenae as type species. Neocochlearomyces is characterized by macronematous and mononematous, subcylindrical, septate, thick-walled conidiophores, with terminal and intercalary conidiogenous cells on one side of the swollen fan-like structure, and falcate, aseptate conidia that are equilateral, convex, obtuse to sub obtusely rounded, forming a slimy spore mass. Neocochlearomyces differs from Cochlearomyces as the latter has synnemata with a swollen spoon-shaped conidiogenous area situated a third below the apex, and has conidia that are cylindrical, lacking setulae. According to Hernández-Restrepo et al. (2019), Neocochlearomyces forms a distinct lineage within Muyocopronaceae while in the analysis of Hongsanan et al. (2020), Neocochlearomyces is related to Paramycoleptodiscus. It is however clear that Neocochlearomyces is a distinct genus in Muyocopronaceae.
