Bambusicolaceae D.Q. Dai & K.D. Hyde

Index Fungorum number: IF 804293


Saprobic on decaying bamboo culms. Sexual morph: Ascomata small, solitary, scattered, immersed, conical, ostiolate, coriaceous. Peridium thin, composed of brown and thick-walled cells of textura angularis, with the basal part composed of thinner, hyaline, smaller cells. Hamathecium of relatively thin, dense, anastomosing and branching interascal filaments. Asci 8-spored, bitunicate, fissitunicate, cylindrical, with a short furcate pedicel, apically rounded, with a shallow ocular chamber. Ascospores 2–3-seriate, slightly broad fusiform, 1-septate, narrowly rounded at both ends, hyaline, surrounded by a gelatinous sheath. Asexual morph: Conidiomata small, pycnothyrial, acerous or subglobose, solitary, scattered, immersed to semi-immersed. Conidiophores indistinct. Conidiogenous cells holoblastic, annelidic, discrete, cylindrical, and smooth. Conidia pale brown to dark brown, 1–3-septate, cylindrical, straight or slightly curved, obtuse at the apex, with many guttules.


Type genus: Bambusicola D.Q. Dai & K.D. Hyde 2012


Notes: The family Bambusicolaceae is established to accommodate the genus Bambusicola which comprises three species. Morphologically, Bambusicolaceae species are similar to genera in Tetraplosphaeriaceae i.e. Tetraploasphaeria, Triplosphaeria and Polyplosphaeria (Tanaka et al. 2009), but Dai et al. (2012) phylogenetically showed Bambusicola species to belong in a different lineage. All the members in Tetraplosphaeriaceae have immersed to superficial, globose to subglobose ascomata, cylindrical to clavate asci and hyaline, fusiform ascospores surrounded by a mucilaginous sheath (Tanaka et al. 2009). Both Triplosphaeria and Bambusicola massarinia D.Q. Dai & K.D. Hyde have similar rim-like side walls (Tanaka et al. 2009; Dai et al. 2012). All genera in Tetraplosphaeriaceae have been linked to “Tetraploa”-like hyphomycetous states (Tanaka et al. 2009), however, coelomycetous states were observed in all species of Bambusicolaceae in culture or on host culms. Molecular data show this family to belong in Pleosporales, related to Massarinaceae and Montagnulaceae.
