Ascomycota, genera incertae sedis

 

Saprobic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata orange-yellow or yellowish white, stromatic, pycnidial, initially immersed, ultimately erumpent, ellipsoid to elongate in outline, cylindrical to broadly conical in section view, unilocular to plurilocular, glabrous, thick-walled, lacking an ostiole but dehiscing by an irregular break in the apical wall, and then opening wide and appearing acervuloid. Conidiomatal wall composed of thick-walled, hyaline cells of textura intricata to textura angularis. Conidiophores arising in the cavity of the conidioma, hyaline, branched and broader at base, septate, smooth-walled, invested in mucus. Conidiogenous cells hyaline, enteroblastic, cylindrical to subcylindrical, discrete or integrated, indeterminate, with or without percurrent proliferation. Conidia hyaline, fliform to elongated obclavate or vermiform, attenuated towards the apex, truncated at the base, variously curved, multiseptate, slightly constricted at the septa, smooth-walled, guttulate, apical cell attenuated into a tubular appendage (Nag Raj and DiCosmo 1982; Nag Raj 1993).

 

Type species: Ebollia valdiviensis (Speg.) Minter & Caine, Trans. Br. Mycol. Soc. 74(2): 436 (1980)

 

Notes: Ebollia was introduced by Minter and Caine (1980) for a species, Trichocrea valdiviensis Speg. segregated from Trichocrea Marchal. The genus is characterized by orange-yellow, embedded to erumpent pycnidia, monoblasts, integrated, cylindrical conidiogenous cells and hyaline, elongated obclavate, multiseptate conidia (Minter and Caine 1980). Nag Raj (1993) added a second species, E. vermispora Nag Raj to the genus, which differs from the type species by its apical appendage. Ebollia has never been studied with molecular sequence, thus new collections of these two species are needed to confirm its placement in a natural classification.

 

Distribution: India, USA.
