Neohortaea
Neohortaea Quaedvl. & Crous, in Quaedvlieg et al., Persoonia 33: 27 (2014).
Index Fungorum number: IF 822608; Facesoffungi number: FoF 08545, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Acidophilic on lignite. Sexual morph: Unknown. Asexual morph: Colonies smooth, mucilaginous, black. Mycelium consisting of pale olivaceous, thin-walled hyphae that become dark brown with thick walls, producing copious mucus. Conidiogenous cells integrated on hyphae, reduced to conidiogenous loci, with several minute per current proliferations. Conidia initially sub hyaline, smooth, thin-walled, ellipsoidal, becoming dark brown, broadly ellipsoid to clavate, septum median, hilum truncate with minute marginal frill; conidiation microcyclic (adapted from Quaedvlieg et al. 2014).
Type species: Neohortaea acidophila (Hölker, Bend, Pracht, Tetsch, Tob. Müll., M. Höfer & de Hoog) Quaedvl. & Crous
Notes: Neohortaea resembles Hortaea but differs in having annellate conidiogenous loci, and conidia that develop several septa, forming chlamydospores with age (de Hoog et al. 2000; Plemenitas et al. 2008). Neohortaea acidophila was previously known as Hortaea acidophila and was taxonomically placed in the Teratosphaeriaceae. Quaedvlieg et al. (2014) provided the new combination Neohortaea acidophila and introduced Neohortaea as a new genus. The placement of Neohortaea is uncertain and is currently in Capnodiales genera incertae sedis. Molecular markers available for Neohortaea are ITS, LSU, SSU and RPB2.
