Querciphoma Crous, in Crous & Groenewald, IMA Fungus 8(1): 147 (2017).
Index Fungorum number: IF 820913; Facesoffungi number: FoF 06404, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Pathogenic on host. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, globose, eustromatic, uni- to multi-locular, with 1–3 papillate ostioles, medium brown, outer surface covered in short, brown, verruculose, septate setae with obtuse ends; wall of 3–6 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells lining inner cavity, hyaline, smooth, doliiform; phialidic with periclinal thickening at the apex. Conidia solitary, hyaline, smooth, guttulate, broadly ellipsoidal, aseptate, becoming brown, verruculose with age (adapted from Crous and Groenewald 2017).
Type species: Querciphoma carteri (Gruyter & Boerema) Crous
Notes: Querciphoma is morphologically similar to Phoma but distinct in having eustromatic, uni- to multi-locular conidiomata and conidia that become brown and verruculose with age. No sexual morph characters are reported for this genus (Wijayawardene et al. 2017). Querciphoma is a distinct and phylogenetically well-supported genus in Leptosphaeriaceae. Molecular markers available for Querciphoma are ITS, LSU, SSU, BTUB, RPB2 and TEF-1.
