Zopfiaceae Arnaud ex D. Hawksw., Syst. Ascom. 11(1): 77 (1992).

MycoBank number: MB 81951; Index Fungorum number: IF 81951; Facesoffungi number: FoF 08390, 13 species.

Saprobic mostly on surface of roots or wood, terrestrial and marine, widespread. Sexual morph: Ascomata cleistothecial or perithecial, superficial or partially erumpent, solitary or clustered, subglobose to globose, rounded above, carbonaceous, dark brown to black, immersed or not immersed under a stroma and clypeus, lacking ostioles and breaking on the top of ascomata at maturity, or ostiolate. Peridium thin- to thick-walled, composed of cells of textura angularis. Hamathecium comprising numerous, septate, filamentous, hyaline, branched, anastomosing, cellular pseudoparaphyses, embedded in a gelatinous matrix. Asci 1–8-spored, bitunicate, fissitunicate, clavate to cylindrical, globose or saccate, short or long pedicellate, dissolving at maturity. Ascospores crowded or partially overlapping, obovate to pyriform or oblong to ellipsoid, hyaline or yellow, to brown when immature, completely black at maturity, aseptate or 1–3-septate, distoseptate, mostly septate at the middle or upper cell, broader than the lower cell, with umbonate ends, smooth-walled or slightly roughened, ornamented or not ornamented. Asexual morph: “cladosporium”-like (Wijayawardene et al. 2012).

TypeZopfia Rabenh.

Notes – The details of Zopfiaceae were outlined in Zhang et al. (2012b) and Hyde et al. (2013). The family comprises six genera, Celtidia, Coronopapilla, Rechingeriella, Richonia, Zopfia and Zopfiofoveola (Wijayawardene et al. 2018). The species in Zopfiaceae mostly lack sequence data. Thus, fresh material needs to be collected, examined and sequenced for epitypifications to verify their natural placement.
