Index Fungorum number: IF 608; Facesoffungi number: FoF 08790, 18 morphological species (Species Fungorum 2022), 4 species with molecular data.

Lichenized on host. Thallus ecorticate, mostly whitish to pale brownish. Photobiont Trentepohlia. Sexual morph: Ascomata solitary, erumpent to prominent, brown-black to carbonaceous, hemisphaerical to wart-shaped or conical, 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(–2) µm wide para-physoids, hyaline, straight to somewhat wavy, branched and anastomosing, embedded in a thin, gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, (ob-)clavate to fusiform, short pedicellate, with a non-amyloid ocular chamber. Ascospores irregularly arranged to uni- or biseriate, fusiform-ellipsoid to oblong, grey-brown, 1–5-septate to small muriform, with eusepta and rectangular lumina or with thickened distosepta making the lumina appear halter-shaped, wall smooth to finely granular ornamented, not constricted at the septa or rarely with constrictions. Asexual morph: Pycnidia known from a few species, immersed to erumpent, visible as black dots. Conidia fusiform, aseptate, bacillar, hyaline. Chemistry: no substances detected by TLC (adapted from Aptroot & Lücking 2016).

 Type species: Bogoriella subpersicina Zahlbr.

Notes: Bogoriella is characterised by ecorticate, mostly whitish to pale brownish thallus, brown-black to carbonaceous, hemispherical to wart-shaped or conical ascomata, bitunicate, fissitunicate, (ob-)clavate to fusiform asci and fusiform-ellipsoid to oblong, grey-brown, 1–5-septate to small muriform ascospores. Sipman and Aptroot (2005) provided details of Bogoriella under the name Mycomicrothelia. Aptroot and Lücking (2016) reinstated Bogoriella to include tropical lichen taxa which were previously placed with non-lichenized taxa in Mycomicrothelia. The phylogenetic placement of only few taxa have been confirmed based on molecular data and Aptroot and Lücking (2016) transferred some species to Distothelia and Novomicrothelia in Trypetheliaceae. Members of Bogoriella are delineated based on ascospore shape and size (Hawksworth 1986, Aptroot 1991, 1995). Hongsanan et al. (2020b) provided molecular phylogeny of Bogoriella based on ‘phenotype-based phylogenetic binning into a molecular reference tree of sequenced species’ and reported Bogoriella as a polyphyletic genus. One clade was named as Novomicrothelia (Aptroot & Lücking 2016, Lücking et al. 2016) while the second clade comprised the type species, B. subpersicina together with the new species B. complexoluminata, both characterised by small muriform ascospores. A third clade comprises Novomicrothelia pandanicola. Hongsanan et al. (2020b) reported that Bogoriella clustered within Novomicrothelia sensu lato based on phylogenetic analyses of mtSSU. Hongsanan et al. (2020b) also provided four new combinations B. chiquitana, B. isthmospora, B. pandanicola and B. rubrostoma and gave a key to accepted species of Bogoriella. Novomicrothelia pandanicola is characterised by small, narrow, muriform ascospores with thin walls and septa and constrictions at the septa while Bogoriella sensu stricto has broadly ellipsoid muriform ascospores with thin or noticeably thickened walls and septa. The species previously classified in Bogoriella sensu lato (as well as Novomicrothelia) represent a polyphyletic group. Bogoriella is a distinct but heterogeneous genus in Trypetheliaceae. Molecular markers available for Bogoriella include mtSSU.
