Pseudoparodia

Pseudoparodia Theiss. & Syd., Annls mycol. 15(1/2): 138 (1917).

Index Fungorum number: IF 4466; Facesoffungi number: FoF 00377, 1 morphological species (Species Fungorum 2022), no molecular data available.

Saprobic on leaves of Vaccinium sp. in terrestrial habitats. Sexual morph: Ascomata perithecial, in small aggregations, superficial with bristles, brittle, spherical, globose, black, in 5% KOH slightly turning to blue-black. Exciple thick and dense, composed of textura angularis, with outer layer comprising of black pseudoparenchyma cells, with thin, inner layer of brown cell of textura angularis. Hamathecium composed of cylindrical, to filiform, septate, unbranched, hyaline, pseudoparaphyses, with filaments slightly wide and swollen at the apex. Asci 4–8-spored, bitunicate, cylindrical, slightly curved, short-pedicellate. Ascospores uni-seriate overlapping, ellipsoid to oblong, rounded at the ends, with upper cell short and rounded, narrow and oblong at the lower part, asymmetrically 1-transverse septate, constricted at the septa, pale brown, smooth-walled. Asexual morph: Unknown (adapted from Yacharoen et al. 2015).

Type species: Pseudoparodia pseudopeziza (Pat.) Theiss. & Syd.

Notes: Pseudoparodia is characterised by perithecial ascomata, cylindrical, slightly curved, short-pedicellate asci and asymmetrically 1-transverse septate ascospores. Petrak (1947) mentioned that Pseudoparodia was related to Venturiaceae. Arx and Müller (1975) placed Pseudoparodia in Stigmateaceae. Zhang and Hyde (2009) reported that the morphological characters of Pseudoparodia differ from members of Venturiaceae as they have superficial and swollen apothecia with dense pseudoparaphyses forming epithecium above the asci which is typical to those of Patellariaceae. Zhang and Hyde (2009), Lumbsch and Huhndorf (2010) accepted Pseudoparodia in Patellariaceae. Yacharoen et al. (2015) examined the holotype of Pseudoparodia (FH 7735) and excluded Pseudoparodia from Patellariaceae based on perithecioid, globose ascomata with black bristles attached to host surface. Pseudoparodia is currently placed in Dothideomycetes genera incertae sedis and molecular data is needed to confirm the taxonomic placement of the genus.
