Associated with house dust. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies often covered in slimy masses of conidia or yeast-like cells, occasionally with sparse aerial mycelium; cream-colored, red-brown, olive-brown, dark brown, or black, becoming dark and often leathery with time; margins entire to slightly filiform or fimbriate. Hyphae longitudinally and transversely 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 brown to dark brown, globose to ellipsoidal, 1-septate to aseptate, sometimes constricted at the septum, smooth to lightly rough-walled. Conidia often yeast-like, hyaline, aseptate, smooth-walled, ellipsoidal with round or pointed ends, variable in shape and size, indistinct hilum, budding common, polar, bipolar and multilateral (Humphries et al. 2017).
Notes – Zalariaceae was proposed to accommodate a new genus with two species which resembles the asexual morphs of Aureobasidium and Hormonema. Humphries et al. (2017) treated Zalariaceae as a distinct family in Dothideales mainly based on multi-gene phylogenies. Zalariaceae is phylogenetically distinct from Aureobasidiaceae and Dothideaceae (Thambugala et al. 2014a).
Type genus: Zalaria Visagie, Z. Humphries & Seifert.
