Type species: Staibia connari Bat. & Peres, in Batista et al., Atas Inst. Micol. Univ. Recife 3: 142 (1966).
Notes: Staibia was introduced as a monotypic genus to accommodate an epiphytic fungus occurring on leaves of Connarus suberosus in Brazil and is characterized by subcuticular, dark brown, orbicular, dimidiate, membranous ascomata, lacking ostioles and paraphyses. The upper wall of the peridium is radiate, with longitudinally isodiametric cells, endowed with multiple hymenium, black at the margin and with a poorly-developed base. Asci are 8-spored, bitunicate and globose and ascospores are hyaline, oblong to subovoid and 1-septate (Batista et al. 1966). The asexual morph of this genus is undetermined. Batista et al. (1966) treated the genus in Leptopeltidaceae and this was followed by subsequent authors (von Arx and Müller 1975; Lumbsch 2014a, 2018). The genus is poorly known and lacks molecular data to reveal its taxonomic status, hence, it was tentative placed in this family pending further studies.
