Parasterinopsis Bat., Atas Inst. Micol. Univ. Recife 1: 327 (1960).
Epiphytes on surface of leaves. Superficial hyphae abundant, superficial, light brown, septate, branching and spreading over the host surface. Appressoria lateral, 2-celled narrowly ovate. Sexual state: Sexual state: Thyriothecia superficial, scattered, black, opening by huge irregular fissure when wet, with basal peridium poorly developed. Upper wall composed of dark to brown filaments at the outer rim, which radiate towards the rim. Hamathecium filamentous, branched pseudoparaphyses and vertically arranged asci. Asci 8-spored, bitunicate, oblong, apedicellate, lacking an ocular chamber, not staining blue in IKI. Ascospores fasciculate, cylindrical, hyaline to brown, 1–4-septate, constricted at the septa, with upper cell larger and broadly rounded. Asexual state: Unknown.
Notes: Parasterinopsis was introduced by Batista (1960b) based on Patouillardina sersalisiae and remained monotypic until two species, P. caesalpiniae Batista & H. Maia and P. orchidacearum Bat. & Peres were added by Batista et al. (1963). Patouillardina sersalisiae had been collected from Uganda, but the specimen appears to be housed in URM and we are not sure if it still can be located in the Uganda herbarium. The genus is retained in Asterinaceae because the thyriothecia open by an irregular fissures and the superficial hyphae with appressoria. The genus is unusual in having cylindrical, 1–4- septate ascospores. It is very similar to Schenckiella in having cylindrical ascospores and may be a synonym. These genera differ as Schenckiella is reported to lack appressoria, however this certainly needs rechecking with fresh material.
Type species: Parasterinopsis sersalisiae (Hansf.) Bat., Atas Inst. Micol. Univ. Recife 1: 327 (1960)
