Phaeosphaeria herpotrichoides  

Anamorph: Stagonospora sp. Conidiomata pycnidia, to 450 µm diam, ± globose with a papillate ostiole, thick-walled (to 40 µm). Conidiophores absent. Conidiogenous cells formed from the inner cells of the peridium, doliiform, proliferation obscure. Conidia 16-32 x 2.5-3.5 µm, cylindrical, the apex rounded to obtuse and the base truncate, 3- to 7-septate, golden brown, thin- and smooth-walled, sometimes with a globose apical gelatinous appendage.
Teleomorph: Ascostromata perithecial, unilocular, 120-150 µm diam, globose to globose-conical, the apex distinctly papillate, scattered or in linear clusters of 2-3, sometimes coalescing, erumpent, black. Peridium composed of 3-4 layers of mid brown thin-walled angular tissue with cells to 8 µm diam. Interascal tissue of copious thin-walled cellular pseudoparaphyses to ca 2.5 µm diam. Asci 84-96 x 9-11 µm, cylindrical to narrowly cylindric-clavate, short-stalked, thick-walled and fissitunicate, the apex rounded with a very inconspicuous ocular chamber, 8-spored. Ascospores 22.5-32 x 4-5 µm, narrowly fusiform, 8- (to 9-) septate, the apex and base acute, constricted at the primary septum, the cell immediately above inflated, with 1(-2) further septa in the upper portion, the lower portion usually 5-septate, pale brown, smooth, with a usually ± uniform mucous sheath.
