Bambusicola D.Q. Dai & K.D. Hyde

Index Fungorum number: IF 801041


Saprobic on decaying bamboo or parasitic on living plant materials in terrestrial or freshwater habitats. Sexual morph: Ascostromata solitary to gregarious, immersed or semi-immersed and becoming erumpent, variable in shape, conical, convex or dome-shaped to ampulliform, globose to subglobose, with centrally located ostiole, with or without red pigment in the ostiole, uni- to multi- loculate, coriaceous, visible as raised, dark spots or elongate structures on host surface. Peridium composed of dark cells of textura angularis or textura epidermoidea or pseudoparenchymatous cells, normally with the flattened base comprising of thinner, hyaline, smaller cells or intermingling with host cells. Pseudoparaphyses dense, trabeculate, filiform, hyaline, indistinctly septate, anastomosing and branching above the asci. Asci 8-spored, bitunicate, cylindrical or cylindric-clavate, short pedicellate, with a shallow or well-developed chamber. Ascospores uni- to tri-seriate, fusiform, septate, mostly hyaline, rerely pale brown, mostly surrounded by a gelatinous sheath. Asexual morph: Coelomycetous. Conidiomata pycnothyrial, solitary to gregarious, scattered, immersed to semi-immersed, acerose or subglobose, pyriform or irregular, uni- to multi-loculate. Pycnidial wall composed of several layers, thin- to thick- walled, hyaline to dark brown cells of textura globulosa or textura angularis. Conidiophores indistinct. Conidiogenous cells holoblastic, annellidic, discrete, cylindrical, smooth. Conidia sometimes two types, macro and microconidia. Macroconidia cylindrical to ellipsoidal, pale brown to brown, septate, smooth, guttulate. Microconidia globose, oblong to ellipsoidal, hyaline to pale brown, aseptate, smooth, guttulate.


Type species: Bambusicola massarinia D.Q. Dai & K.D. Hyde, in Dai, Bhat, Liu, Chukeatirote, Zhao & Hyde, Cryptog. Mycol. 33(3): 370 (2012)


Notes: Bambusicola is well-studied because all species have sequence data in GenBank. Bambusicola is distinct in Bambusicolaceae in having fusiform, hyaline, mostly smooth-walled ascospores and cylindrical to ellipsoidal or globose conidia (Dai et al. 2012). The asexual morphs can be found in natural substrate (Bambusicola splendida D.Q. Dai & K.D. Hyde and B. irregulispora D.Q. Dai & K.D. Hyde) or in culture (B. massarinia D.Q. Dai & K.D. Hyde) (Dai et al. 2012). Bambusicola sometimes produces two types of conidia, such as B. dimorpha Thambugala et al. producing macro and micro conidia (Thambugala et al. 2017). Other Bambusicola species only formed macroconidia characterized as cylindrical to ellipsoidal, pale brown to brown, septate conidia. Bambusicola species are saprobic on decaying bamboo from Thailand or parasitic on living leaves or branches of Phyllostachys heteroclada Oliv. from China (Dai et al. 2012, 2015, 2017; Thambugala et al. 2017; Yang et al. 2019). Herein, we report a new Bambusicola species isolated from submerged wood in China.
