Type species – Setoarthopyrenia chromolaenae Mapook & K.D. Hyde, Fungal Divers 101: 92 (2020).
Notes – A monotypic genus Setoarthopyrenia was introduced by Mapook et al. (2020) to accommodate the sexual morph taxon forming solitary, semi-immersed, globose to subglobose, ascomata, with setae near the papilla, bitunicate, cylindric-clavate to obclavate asci and hyaline, fusiform, 1-septate ascospores. The genus was found as a saprobe on dead stem of Chromolaena odorata (Asteraceae) in Thailand. The asexual morph of Setoarthopyrenia is unkown. Multi-gene phylogenetic analyses showed that the genus is closely related to Arthopyrenia sp. strain UTHSC: DI16-362 in Roussoellaceae (Mapook et al. 2020).
