Zalaria
Zalaria Visagie, Z. Humphries & Seifert, in Humphries et al., IMA Fungus 8(2): 307 (2017).
Index Fungorum number: IF 821628; Facesoffungi number: FoF 07668, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.
Pathogenic to humans. Sexual morph: Unknown. Asexual morph: Colonies covered in slimy masses of conidia or yeast-like cells, becoming dark and often leathery with time, occasionally with sparse aerial mycelium; cream-colored, red-brown, olive-brown, dark brown, or black; margins entire or fimbriate. Hyphae transversely and longitudinally septate, hyaline and thin-walled when young, frequently becoming melanized and thick-walled with age, may develop into chlamydospores. Conidiogenous cells undifferentiated, intercalary, terminal uncommon, cylindrical, with blastic conidiogenesis occurring from one to two loci per cell. Chlamydospores dark brown, smooth to lightly rough-walled, globose to ellipsoidal, septate. Conidia often yeast-like, hyaline, aseptate, smooth-walled, ellipsoidal to lemon-shaped, variable in size, indistinct hilum, budding common, polar, bipolar and multilateral (adapted from Humphries et al. 2017).
Type species: Zalaria obscura Visagie, Z. Humphries & Seifert
Notes: Zalaria accommodates aureobasidium-like species. Zalaria differs from Aureobasidium in having blastic conidiogenesis occurring from one to two loci per conidiogenous cell. Zalaria is phylogenetically a distinct genus and is accommodated in its own family Zalariaceae. LSU, SSU, ITS, BTUB and RPB2 sequences are available in GenBank for Zalaria.
