Kabatiella Bubák, Hedwigia 46: 297 (1907).

Index Fungorum number: IF 8656; MycoBank number: MB 8656; Facesoffungi number: FoF 00103; 19 morphological species (Species Fungorum 2020), 6 species with molecular data.

Subepidermal on leaves. Sexual state: Unknown. Asexual state: Conidiomata sporodochia or acervuli, stromata, pale or pale brown. Conidiophores stromatic, unbranched, or branched, hyaline. Conidiogenous cells polyblastic synchronous, inconspicuous scars orndenticles, vesiculate, hyaline. Conidia clustered on swollen apex, borne on tiny sterigmata, aseptate, hyaline, oblong to cylindrical, conidial secession schizolytic (Bubák and Kabát 1907; Seifert et al. 2011).

Type species – Kabatiella microsticta Bubák, Hedwigia 46: 297 (1907).

Notes – Kabatiella is characterized by polyblastic synchronous, inconspicuous scars on denticles, vesiculate conidiogenous cells and aseptate, hyaline, oblong to cylindrical conidia. Several authors have synonymized Kabatiella under Aureobasidium (Hermanides-Nijhof 1977, Sivanesan 1984), but Seifert et al. (2011) and Thambugala et al. (2014a) treated these two genera as separate. Kabatiella species need to be sequenced to resolve taxonomic boundaries of Aureobasidium and Kabatiella. No sexual morph has been linked to the genus.
