Index Fungorum number: IF 551921; Facesoffungi number: FoF 01827, 4 morphological species (Species Fungorum 2021), 4 species with molecular data.
Saprobic on dead stem of Spartium junceum L. Sexual morph: Ascomata immersed in epidermis, solitary, scattered or in small groups, globose to subglobose, smooth, black to dark brown, ostiolate. Ostioles centrally located, globose or oblong, ostiolar canal filled with periphyses. Peridium comprising 2-3 layers of dark brown to light brown cells of textura angularis. Hamathecium of numerous, dense, long, cellular psedoparaphyses, septate, tapering, branched, anastomosing. Asci 8-spored, bitunicate, clavate, fissitunicate, short pedicellate, thick-walled, apically rounded, with an ocular chamber. Ascospores bi-seriate or partially overlapping, oval to ellipsoidal, slightly conical at the apex, yellowish when mature, 3-transversely septate, rarely 1-2-septate, slightly constricted at the septa, containing granules in the middle cells, smooth walled, surrounded by a wide mucilaginous sheath. Asexual morph: Hyphomycetous. Mycelium smooth, pale brown to brown, septate, branched. Conidiophores semi-macronematous to macronematous, erect, septate, branched, slightly constricted at the septa, pale brown to brown. Conidiogenous cells annellidic, holoblastic, doliform, integrated, terminal, indeterminate, smooth to verrucose, pale brown. Conidia dictyosporous, coiled, involute, acropleurogenous, brown to dark brown, solitary, with granules (Adapted from Phukhamsakda et al. 2016).
Type species: Sparticola junci Phukhams., Camporesi & K.D. Hyde
Notes: Sparticola was introduced by Phukhamsakda et al. (2016) with S. junci as type species. Sparticola is characterized by globose to subglobose, smooth ascomata, clavate, fissitunicate, short pedicellate asci and oval to ellipsoidal 1-2-septate ascospores. Sparticola resembles members of Sporormiaceae in having globose, black, coriaceous, ostiolate ascomata and a peridium of thin-walled cells of textura angularis (Phukhamsakda et al. 2016). Sparticola differs from species of Sporormiaceae in having ascospores with transverse septa, absence of a germ slit, yellowish to light brown, and occurrence on Spartium junceum in terrestrial habitats, while taxa in Sporormiaceae are characterized by dark brown, multi-septate ascospores, separating in to part spores, with a germ slit, and have a coprophilous lifestyle (Kruys and Wedin 2009; Phukhamsakda et al. 2016). Sparticola is morphologically and phylogenetically a distinct genus in Sporormiaceae.
