Colonies effuse, brown, composed of conidiophores, mycelium immersed. Teleomorph: Unknown. Anamorph: Setae absent. Conidiophores macronematous, single or in groups, erect, straight or flexuous to geniculate in the upper part, unbranched, septate, smooth, brown, paler toward the apex. Conidiogenous cells integrated, terminal, polyphialidic, extending sympodially, paler than the conidiophore, often with persistent remnants of the collarettes; collarettes flared, soon evanescent. Conidia ellipsoidal, fusiform, subglobose, rounded at the apical end, papillate at the basal end, aseptate, hyaline, with a straight or gently curved setula at each end, basal setulae positioned ventrally, conidia accumulate in slimy whitish fascicles (Adapted from Réblová et al. 2021b).

Ecology/Substrate/Host: Saprobe on decaying plant material.

Geographical distribution: Asia, South American, including China and New Zealand (Réblová et al. 2021a).

Description and illustration: Réblová et al. (2021b).

Notes: The genus Nimesporella, typified by N. capillacea, is characterized by absence of setae, septate conidiophores bearing terminal polyphialidic conidiogenous cells with sympodially extending and flared collarettes, and hyaline, aseptate, ellipsoidal to fusiform, papillate conidia with one setula at both ends (Réblová et al. 2021b). Our phylogenetic analysis with 3 additional species showed that members of this genus formed a distinct clade from other known Codinaea and Dictyochaeta species. Apart from the three species presented in this study, several published species with similar morphology as N. capillacea are also assigned to the genus, including Dictyochaeta aliformis, Codinaea aquatica, Codinaea leomaiae, D. tumidospora and Hyphodiscosia queenslandica (Hughes and Kendrick 1968; Holubová-Jechová 1984; Kuthubutheen and Nawawi 1991a, b; Bhat and Kendrick 1993; Whitton et al. 2000; Seifert et al. 2011; Oliveira et al. 2015 ; Barbosa et al. 2016; Arias et al. 2018).
