Cladosterigmoideae Piątek, Stryjak-Bogacka & Czachura subfam. nov.

Etymology.

Named after the genus Cladosterigma .

Description.

Non-lichenized, plant associated or fungicolous fungi. Conidiomata sporodochial, synnematal, eustromatic or conidiophores arising directly from hyphae. Conidiophores hyaline, smooth, subcylindrical, conical, ampulliform or subglobose, branched or not, with terminal and / or intercalary conidiogenous cells, sometimes reduced to conidiogenous cells. Conidia solitary or rarely in chains, hyaline, smooth, 0–1 - septate, ellipsoid, fusoid or subcylindrical. Sexual morph undetermined [based on generic descriptions in Sutton 1980; Guterres et al. 2020; Crous et al. 2019 a, 2021, 2023].

Cladosterigma Pat.

Notes.

This subfamily includes genera Cladosterigma , Cytosporella , Neoacrodontiella , Nothoramularia and Vanderaaea . Members of this subfamily are different morphologically (absence of hyphophores with diahyphae), phylogenetically (distinct, sister lineage in molecular analyses) and ecologically (non-lichenized and non-lichenicolous species) from representatives of the nominative subfamily.
