Rizalia was introduced by Sydow & Sydow (1914). Hyde et al. (2017b) accepted five species in Rizalia, viz. R. byrsonimae, R. confusa, R. fasciculata, and R. glaziovii and R. guianensis. The sixth species was described by Niranjan & Sarma (2018) from India. Rizalia is characterized by globose to pyriform, setose ascomata with long necks, [...]
Nag Raj (1984) reported two sexual morph species of Koorchaloma, including the type species, Ko. madreeya, and erected Kananascus. Based on nomenclatural priority, we synonymize Kananascus with Koorchaloma. The sexual morph of Koorchaloma is characterized by its superficial, globose to pyriform, unilocular and setose ascomata, hyaline, clavate, 8-spored asci with J-, apical rings and [...]
Eriosphaeria was introduced by Saccardo (1875a). The genus is characterized by superficial, setose ascomata and 1-septate, oval ascospores (Réblová 1997). Fresh collections are required to solve the natural classification of Eriosphaeria.
Coniobrevicolla is a monotypic genus introduced by Réblová (1999b) to accommodate C. larsenii, which is saprobic on decayed wood of an unidentified deciduous tree in Denmark. This genus is characterized by superficial, conical, ostiolate ascomata, 8-spored asci with an indistinct apical ring, and ellipsoidal, 3-septate, ascospores with two brown central cells and hyaline end [...]
Brachysporium was introduced by Saccardo (1886). Brachysporium comprise many saprobic wood-inhabiting species (Ellis 1971, Holubová-Jechová 1972, Réblová & Seifert 2004b). Réblová & Seifert (2004b) established the sexual morph genus Cryptadelphia and linked it with Brachysporium asexual morphs. Cryptadelphia was synonymized under Brachysporium due to nomenclatural priority. The sexual morph of this genus is characterised [...]
Saprobic and pathogenic on plants, commonly isolated from herbivore dung. Sexual morph: Ascomata superficial, semi-immersed or immersed, ostiolate, globose to pyriform, dark brown to black, sometimes setose. Ostiole situated in a small papilla, with bristles. Setae absent or present; brown, septate, smooth when present. Peridium carbonaceous, coriaceous or membranaceous, brown to dark brown, comprising [...]
Pycnothyria of Saprothyrium differ in having a scutellum with obtuse outer strands with globose to subglobose hyaline conidia, and is similar with Sphaerosporithyrium. However, it clusters in a phylogenetically distant clade to clades of Tubakia sensu stricto (Braun et al. 2018). Saprothyrium can be distinguished from all other species of Tubakia sensu stricto by [...]
Tubakia species may form different types of asexual morphs. Pycnothyria with typical scutella are a distinct character of this genus. In addition, sporodochial conidiomata are formed with clusters of conidiogenous cells e.g. on leaf veins as in T. iowensis. Crustose or pustulate pycnidioid conidiomata are formed in several Tubakia species, including T. californica, T. [...]
Sphaerosporithyrium is similar with Paratubakia (Braun et al. 2018) in conidial shape and colour. However, the formation of pycnothyria formed by species of the latter genus differs in pointed tips of hyphal scutellum strands. Sphaerosporithyrium is characterized by hyaline globose-subglobose conidia (Braun et al. 2018).
The conidiomata of convex scutella with radiating threads of cells connected to the substratum of type specimen are similar to other genera of Tubakiaceae. However, the genera having hyaline conidia arranged in a line are excluded from Tubakia sensu stricto. Racheliella saprophytica is characterized by crustose conidiomata and it is different from all other [...]
