Index Fungorum number: IF 658; Facesoffungi number: FoF 00626; 14 morphological species (Species Fungorum 2020); 2 species with sequence data.


Saprobic on various monocots, dicots such as bamboo and pine. Sexual morph: Ascomata solitary to gregarious, uniloculate, globose to subglobose, glabrous, papillate. Ostiole centrally positioned, comprising of longitudinal cells, internally lined with hyaline periphyses. Peridium composed of light brown, thick-walled cells of textura prismatica in the upper part, and thin-walled, hyaline to pale brown cells in other parts. Hamathecium comprising of cylindrical, septate, paraphyses. Asci 8-spored, unitunicate, cylindrical to cylindrical-clavate, short pedicel, apically rounded, with a J- apical ring. Ascospores biseriate or overlapping bi- or tri-seriate, fusiform, median cells pale yellowish brown to greyish brown, end cells grey or hyaline, glabrous, straight or inequilaterally curved, 3-septate, constricted at the mid septa, thick-walled, each end cell bearing a simple, centric, cylindrical appendage. Asexual morph: Coelomycetous. Conidiomata stromatic, pycnidioid, scattered to gregarious, immersed to semi-immersed, oval or elongated, black, unilocular, papillate, glabrous. Pycnidial wall outer layers pale brown to brown cells of textura globulosa to textura angularis, composed of thick-walled, inwardly integration with relatively thin-walled, colourless cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells integrated, cylindrical, phialidic, percurrently multiplying 1–2-times, hyaline, and smooth. Conidia pale brown or brown, fusiform to aciculate, with acute ends, straight or slightly curled, 3-septate, constricted at septa, verruculose, thick walled, and bearing up to 5 appendages at the apex and a single appendage at the base (adapted from Maharachchikumbura et al. 2016).


Type species: Broomella vitalbae (Berk. & Broome) Sacc., Syll. fung. (Abellini) 2: 558 (1883)


Notes: Broomella species have been mostly reported from Asia and Europe (Farr & Rossman 2019), as saprobes from terrestrial habitats (Li et al. 2015, Wijayawardene et al. 2018).The sexual morph is characterized by cylindric-elongate, unitunicate asci, with J-, discoid apical ring, bearing 2-3-septate, ellipsoid-fusiform ascospores with brown, median and hyaline, terminal cells bearing centric appendages at each end (Shoemaker & Müller 1963, Li et al. 2015, Wanasinghe et al. 2018, Liu et al. 2019). The asexual morph is pestalotia-like and this is yet to be confirmed by phylogeny (Wanasinghe et al. 2018, Liu et al. 2019). Li et al. (2015) provided an epitype for Broomella vitalbe illustrating both its sexual and asexual morphs.
