Ebollia vermispora

Ebollia vermispora Nag Raj, Coelomycetous Anamorphs with Appendage-bearing Conidia: 342 (1993)

Facesoffungi number: FoF 07355

 

Saprobic on dead bamboo twigs kept in moist chamber for 7 days. Sexual morph: undetermined. Asexual morph: Conidiomata 100350 diam., 100250 µm wide, appearing as yellowish white blisters, stromatic, pycnidial, solitary to gregarious or confluent, immersed in origin, becoming partly erumpent late, ellipsoid to elongate in outline, cylindrical to broadly conical or irregular in section view, unilocular or multilocular, locule often irregularly divided and convoluted, glabrous, thick-walled, lacking an ostiole but dehiscing by an irregular break in the apical wall. Conidiomatal wall 1030 µm wide, composed of thick-walled, hyaline cells of textura intricata in outer layers, gradually merging with thin-walled, hyaline cells of textura angularis in innermost layers. Conidiophores arising in the cavity of the conidiomata, hyaline, branched and broader at base, septate, smooth-walled, invested in mucus. Conidiogenous cells 410 × 12 µm, hyaline, enteroblastic, subcylindrical, straight or slightly curved, sometimes narrowed at middle part, discrete or integrated, indeterminate, percurrently proliferating several times. Conidia 67–112 × 23 µm ( = 91 × 2.3 µm; n = 30), hyaline, vermiform, with an obtuse base, variously curved, attenuated towards the acuminate apex, 712-septate, slightly constricted at the septa, smooth-walled, guttulate, with apical cell attenuated into a tubular appendage; conidia extruded in a gloeoid mass or in long cirrhi.

 

Material examined: India, Tamilnadu, Coonoor, Nilgiri Hills, on dead bamboo twigs kept in moist chamber for 7 days, 28 September 1980, T.R. Nag Raj (DAOM 215251, holotype).
