Classification: Incertae sedis, Incertae sedis, Incertae sedis, Pezizomycetes, Pezizomycotina, Ascomycota, Fungi
Ascomata apothecial, gregarious, discoid to pulvinate, sessile. Ectal excipulum composed of subangularis to globose cells, which are pigmented with carotenoid (yellowish to orangish) pigments. Medullary excipulum composed of cells of textura intricata. Paraphyses filiform, septate, branched, apically curved. Asci operculate to suboperculate, non-amyloid, cylindrical, with or without croziers, 8-spored. Ascospores globose to ellipsoid, guttulate, hyaline, uniseriate.
Genera included: Pulvinulaa,b, Lazuardiaa,b, Pseudobouboviaa,b (aOperculate asci, bmolecular data available) Notes: Hansen et al. (2013) suggested separating the Pulvinula-Lazuardia lineage from Pyronemataceae. According to our phylogenetic analysis Pulvinula, Lazuardia, Pseudoboubovia formed a separate clade close to Ascodesmidaceae. Therefore, here we introduce the Pulvinula-Lazuardia clade as a new family Pulvinulaceae.
Type species: Pulvinula convexella (P. Karst.) Pfister, Occ. Pap. Farlow Herb. Crypt. Bot. 9: 9 (1976)
