MycoBank number: MB 821540; Index Fungorum number: IF 821540; Facesoffungi number: FoF 03461; 1 species.
Foliicolous. Sexual morph: Undetermined. Asexual morph: Conidiomata amphigenous, pycnidial, globose, orange-coloured with dark brown border on leaves. Peridium comprises pale brown cells of textura angularis. Paraphyses hyaline, subcylindrical, septate, branched or unbranched, with obtuse apex, constricted at septa. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, annellidic, smooth, ampulliform, with terminal truncate locus, thick- walled, sometimes proliferating percurrently. Conidia ellipsoidal, smooth, solitary, median 1- septate, constricted at septum, obtuse at apex, truncate at base, thickened, at times with marginal frill, becoming golden brown at germination and with solitary, brown, wavy, thick, bright banded, germ-slit along the long-axis of the conidium (adapted from Senanayake et al. 2017a).
Type genus – Auratiopycnidiella Crous & Summerell
Notes – Following molecular analysis, Crous et al. (2012b) introduced Auratiopycnidiella based on A. tristaniopsis and placed it in Diaporthales genera incertae sedis. Senanayake et al. (2017a) introduced Auratiopycnidiellaceae to accommodate Auratiopycnidiella. In this study we illustrate A. tristaniopsis.
