Ebollia vermispora Nag Raj, Coelomycetous Anamorphs with Appendage-bearing Conidia: 342 (1993)
Saprobic on dead bamboo twigs kept in moist chamber for 7 days. Sexual morph: undetermined. Asexual morph: Conidiomata 100–350 diam., 100–250 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 10–30 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 4–10 × 1–2 µm, hyaline, enteroblastic, subcylindrical, straight or slightly curved, sometimes narrowed at middle part, discrete or integrated, indeterminate, percurrently proliferating several times. Conidia 67–112 × 2–3 µm ( = 91 × 2.3 µm; n = 30), hyaline, vermiform, with an obtuse base, variously curved, attenuated towards the acuminate apex, 7–12-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.
