Nothopericoniella Videira & Crous, in Videira et al., Stud. Mycol. 87: 364 (2017).
Phytopathogenic. Sexual morph: Unknown. Asexual morph: Mycelium mainly superficial, composed of brown and verrucose hyphae, internal mycelium sparsely developed, intracellular, composed of hyaline to brown hyphae, finely verruculose, septate, branched. Conidiophores solitary, arising from superficial hyphae, erect, straight, septate, brown olivaceous, paler at the apex, smooth to verruculose, composed of a main axis with a dichotomously branched apical head, branches terminal, partly lateral, proliferating percurrently and sympodially. Conidiogenous cells integrated, terminal and pleurogenous, polyblastic, sympodial, geniculate or sub-denticulate, conidiogenous loci slightly thickened and darkened, truncate, without marginal rim or papillae. Conidia solitary, rarely in short chains, ellipsoid-ovoid, subcylindrical, verruculose, pale olivaceous, apex rounded, base obconically truncate, hila slightly thickened and darkened (adapted from Videira et al. 2017).
Type species: Nothopericoniella perseae-macranthae (Hosag. & U. Braun) Videira & Crous
Notes: Nothopericoniella was introduced by Videira et al. (2017) with N. perseae-macranthae as type species. Nothopericoniella resembles Annellosympodiella in having percurrent and sympo-dial proliferation, verrucose conidiophores and conidia and conidiogenous scars lacking marginal rim or papillae but somewhat thickened and darkened. Nothopericoniella differs from Annellosympodiella in forming longer conidiophores that rise singly from the external mycelium and are branched at the top instead of forming straight conidiophores rising from stromata in densely aggregated bunches and in having shorter conidia. Phylogenetically, Nothopericoniella is a distinct genus in Mycosphaerellaceae.
