Batistinula Arx, Publções Inst. Micol. Recife 287: 4 (1960).
Epiphytes on surface of leaves. Superficial hyphae branched, septate, dark brown, radiating, with lateral, conical appressoria. Sexual state: Thyriothecium superficial on host tissues, globose, dark brown to black, joined to branching mycelial out the outside, with a central ostiole. Hamathecium with sparse cylindrical, pale brown, branched, septate, pseudoparaphyses. Asci 8–spored, mostly broadly clavate, somewhat ovoid, with a short pedicle, apically thickened region not obvious. Ascospores brown, 3-septate, with smaller ends cells. Asexual state: Unknown.
Notes: Batistinula is characteristic of the family Asterinaceae. Ascospores are 3-septate and resemble those of Halbania, but in Halbania superficial mycelia lack appressoria indicating the genera are not synonymous.
Type species: Batistinula gallesiae Arx, Publções Inst. Micol. Recife 287: 6 (1960).
