Sporormia

Sporormia De Not., Micr. Ital. Novi 5: 10 (1845).

Hormospora De Not., G. bot. ital. 2(1): 46 (1844).

Index Fungorum number: IF 5169; Facesoffungi number: FoF 06569, 28 morphological species (Species Fungorum, 2022), 3 species with molecular data.

Saprobic on dung. Sexual morph: Ascomata solitary, scattered, immersed to erumpent, globose to subglobose, black, smooth, apex without an obvious papilla, ostiolate. Peridium membranaceous, thin, composed of brown, relatively thick-walled cells. Hamathecium comprising sparse septate, cellular pseudoparaphyses. Asci 8-spored, bitunicate, short, cylindrical, with a short, narrowed, furcate pedicel, lacking an apical apparatus. Ascospores fasciculate, 15–32-celled, cylindrical, dark brown at maturity, smooth, multiseptate, easily separating into part-spores, germ pores absent, germ slits usually absent, spores joined together in a truncate bundle with one common gelatinous coat, better observable when released from the ascus. Asexual morph: Unknown (Adapted from Hyde et al., 2013).

 

Type species: Sporormia fimetaria (Rabenh) De Not.

 

Notes: Sporormia was introduced by de Notaris (1845) with Sporormia fimetaria as type species. Sporormia is characterized by solitary, scattered, immersed to erumpent ascomata, short, cylindrical, with a short, narrowed, furcate pedicel asci and fasciculate, 15–32-celled, cylindrical, dark brown ascospores. Ahmed and Cain (1972) provided a monograph of Sporormia and Sporormiella. Sporormia fimicola is unique among all species of Sporormia in having 29–32-celled ascospores with germ slits. Several authors added new species to Sporormia (Griffiths, 1901; Tengwall, 1924; Viégas, 1943; Faurel & Schotter, 1965; Ahmed & Asad, 1968; Ramesh, 1987). Sporormia is morphologically and phylogenetically a distinct genus in Sporormiaceae.
