Pseudomorfea
Pseudomorfea Punith., Mycol. Pap. 149: 33 (1981).
Index Fungorum number: IF 4458; Facesoffungi number: FoF 12435, 1 morphological species (Species Fungorum 2022), no molecular data available.
Saprobic. Sexual morph: Mycelium spreading, superficial, dense, blackish brown to black, non setose, non hyphopodiate, composed of branched septate, smooth, constricted hyphae with cylindrical to subglobose cells. Ascostromata perithecial, superficial, subglobose, ostiolate, setose. Perithecial wall composed of many layers of pseudoparenchymatic cells. Asci cylindrical to subclavate, stipitate, 8-spored, ascus wall thin, usually with thickened apex, bitunicate, becoming evanescent. Paraphyses or interthecial tissue hyaline, simple, septate, unbranched, conspicuous in immature perithecia. Periphyses hyaline, simple, septate, unbranched, conspicuous in immature perithecia. Ascospores initially distichous finally polystichous, yellowish brown to brown, ellipsoid, usually with 3-transverse septa, sometimes with 3 transverse septa and 1 longitudinal or oblique septum, slightly or not constricted at the septa. Asexual morph: Chaetasbolisia. Mycelium spreading, superficial, dense, brown to black, non setose, non hyphopodiate, composed of branched, septate, smooth, constricted hyphae with cylindrical to subglobose cells. Pycnidia superficial, subglobose, sessile, gregarious, brown, ostiolate, setose. Pycnidial wall composed of several layers of thin-walled pseudoparenchymatic cells. Conidiophores absent. Conidiogenous cells hyaline, ovoid to ampulliform, enteroblastic phialidic, integrated. Conidia hyaline, dull yellow, globose, smooth (adapted from Punithalingam 1981).
Type species: Pseudomorfea coffeae Punith.
Notes: Pseudomorfea is characterised by perithecial, superficial, subglobose, ostiolate ascostromata, cylindrical to subclavate, stipitate, 8-spored asci, and yellowish brown to brown, ellipsoid ascospores. The asexual morph is characterised by superficial, dense, brown to black mycelium, hyaline, ovoid to ampulliform, enteroblastic phialidic conidiogenous cells and hyaline or dull yellow, globose, smooth conidia. Lumbsch and Huhndorf (2010), Kirk et al. (2013), and Wijayawardene et al. (2017, 2020) listed Pseudomorfea in Dothideomycetes genera incertae sedis. Molecular data is lacking. Fresh collections with DNA sequence data are needed to confirm the systematic position of Pseudomorfea.
