Barrina, a new fungal genus with polysporous asci, is described from dead leaves of Dasylirion, a member of the Agavaceae. Polyspory in Barrina arises through formation of ascoconidia by small branched filaments derived from the ascospores within the ascus, a process not previously reported for the Pyrenomycetes.

Two new fungal genera are described from leaves of Dasylirion, a member of the Agavaceae. Comminutispora is set apart by a combination of ascomatal features and its polysporous asci. The new genus and species Hyphospora agavaciensis is established for the anamorph of Comminutispora agavaciensis. Reproduction by means of endoconidia, not blastoconid...

... The term meristematic fungi was introduced to accommodate fungi that have aggregates of thick-walled, melanised cells that enlarge and reproduce by isodiametric division (de Hoog & Hermanides-Nijhof 1977, Sterflinger et al. 1999. Different genera, such as Sarcinomyces (Lindner 1898), Phaeotheca (Sigler et al. 1981), Hyphospora (Ramaley 1996), Endoconidioma (Tsuneda et al. 2004), Endosporium (Tsuneda et al. 2008) and the recently described Gobabebomyces (Crous et al. 2020), have been considered to be members of this unique group of fungi. ...
... However, in certain ascomycete species, conidia are formed directly from the ascospores within asci of fresh and/or dried specimens, or after the ascospores are ejected. This phenomenon is uncommon in ascomycetes and has occasionally been described in several classes: Saccharomycetes from Saccharomycotina; Neolectomycetes and Taphrinomycetes from the Taphrinomycotina; and Lecanoromycetes, Leotiomycetes, Pezizomycetes and Sordariomycetes from the Pezizomycotina (Seaver, 1942;Juzwik and Hinds, 1984;Hawksworth et al., 1995;Ramaley, 1997;Baral, 1999;Wang et al., 2002;Ertz and Diederich, 2004;Neiman, 2005;Frisch and Klaus, 2006;Réblová and Mostert, 2007;Hirooka et al., 2012;Quijada, 2015;Réblová et al., 2015;Zeng and Zhuang, 2016;Lechat et al., 2018;Réblová and Štěpánek, 2018;Quijada et al., 2019;Van Vooren, 2020;Huang et al., 2021;Karakehian et al., 2021). ...
... The ancestral state of the present assemblage of taxa is likely to be saprobic, as Phaeotheca (Sigler et al. 1981, de Hoog et al. 1997, Tsuneda et al. 2004), and Comminutispora (Ramaley 1996) represent the earliest diverging lineages. This was similarly found for a majority of lineages in the larger context of Ascomycota (Schoch et al. 2009a, b). ...

... They can be saprobes on dung, plant litter or in soil, strongly acidic water with high heavy metal concentrations and food. As well, they can be pathogenic on plants or animals, and rarely in humans in terrestrial, freshwater and marine habitats (Ramaley 1997, Weber 2002, Weber et al. 2002, Huhndorf et al. 2004, García et al. 2006, Kirk et al. 2008, Damm et al. 2010, Maharachchikumbura et al. 2015, Wijayawardene et al. 2017a, Wanasinghe et al. 2018, Jones et al. 2019. holotype). ...
