Pseudobogoriella
Pseudobogoriella Lücking, R. Miranda & Aptroot, in Hongsanan et al., Fungal Diversity: 10.1007/s13225-020-00462-6, [171] (2020).
Index Fungorum number: IF 836794; Facesoffungi number: FoF 08807, 15 morphological species (Species Fungorum 2022), 3 species with molecular data.
Lichenized (sometimes barely so or apparently nonlichenized) on bark in terrestrial, mainly lowland to lower montane tropical habitats. Thallus ecorticate, mostly whitish to pale brownish or pinkish. Photobiont Trentepohlia. Sexual morph: Ascomata solitary, erumpent to prominent, brown-black to carbonaceous, hemispherical to wart-shaped, coriaceous to carbonaceous, ostiolate, ostiole apical to rarely lateral. Involucrellum usually well-developed, carbonaceous. Excipulum prosoplectenchymatous, usually brownish, in lateral and apical parts typically fused with the involucrellum. Hamathecium comprising 1 µm wide para-physoids, hyaline, straight to somewhat wavy, branched and anastomosing, embedded in a thin, gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, clavate to fusiform, short pedicellate, with a nonamyloid ocular chamber. Ascospores irregularly arranged to uni- or biseriate, fusiform-ellipsoid, grey-brown, uniseptate, with eusepta and rectangular lumina, wall finely granular ornamented, not or slightly constricted at the septa, typically rather small (mostly around 15–20 × 6–8 µm), only in the type species somewhat larger. Asexual morph: Pycnidia known from a few species, immersed to erumpent, visible as black dots. Conidia aseptate, bacillar, hyaline. Chemistry: no substances detected by TLC (adapted from Hongsanan et al. 2020b).
Type species: Pseudobogoriella hemisphaerica (Müll. Arg.) Lücking, R. Miranda & Aptroot
Notes: Pseudobogoriella was established based on topology of the phylogenetic tree of Hongsanan et al. (2020b) where members of Mycomicrothelia sensu lato formed three distinct clades. Pseudobogoriella differs from Bogoriella sensu stricto in having small, uniseptate ascospores lacking endospore thickenings. Pseudobogoriella currently represents a paraphyletic clade and the taxonomic placement of members of Pseudobogoriella in Trypetheliaceae is not yet established due to lack of molecular data. Molecular markers are available for the following species P. miculiformis (LSU, SSU, TEF-1 and mtSSU), P. minutula (mtSSU) and P. hemisphaerica (LSU, SSU, TEF-1 and mtSSU).
