Nothoanungitopsis

Nothoanungitopsis Crous, in Crous et al., Fungal Systematics and Evolution 7: 305 (2021).

Index Fungorum number: IF 839296; Facesoffungi number: FoF 11942, 1 morphological species (Species Fungorum 2022), no molecular data available.

Mycelium consisting of brown, finely verruculose, septate, branched hyphae. Sexual morph: Unknown. Asexual morph: Conidiophores dimorphic. Microconidiophores erect, flexuous, brown, thick-walled, septate. Macroconidiophores erect, flexuous, brown, finely verruculose, unbranched, thick-walled, base swollen, with rhizoids, multiseptate. Conidiogenous cells terminal, integrated, medium brown, finely verruculose, with several sympodially arranged flat-tipped denticles, scars unthickened. Conidia solitary or in chains of two, fusoid, 3-septate, straight, apex subobtuse, base subobtuse with truncate hilum; two central cells brown, thick walled, finely verruculose; end cells subhyaline, smooth, thin-walled (adapted from Crous et al. 2021).

Type species: Nothoanungitopsis urophyllae Crous

Notes: Nothoanungitopsis is characterised by erect, flexuous, brown, thick-walled micro conidiophores, erect, flexuous, brown, finely verruculose macroconidiophores, terminal, integrated, medium brown, finely verruculose conidiogenous cells and fusoid, 3-septate conidia. Nothoanungitopsis resembles Anungitopsis in having unthickened conidiophore scars and conidial hila but differs in lacking globose, brown swellings in its conidiophores, and having conidia that are unequally pigmented, with two brown central cells (Crous et al. 2021). Nothoanungitopsis is morphologically and phylogenetically a distinct and well-defined genus in Microthyriaceae. Molecular markers available for Nothoanungitopsis are ITS and LSU.
