The order Asterinales comprises a single family, Asterinaceae. In this study, types or specimens of 41 genera of Asterinaceae are re-examined and re-described and illustrated by micrographs.

Asterinaceae are small obligately biotrophic pathogens growing superficially on living leaves of higher plants in tropical and subtropical regions worldwide. The species-rich but rarely studied ascomycete group has an uncertain placement within the Dothideomycetes because molecular data are missing completely up to now. Based on nuclear DNA from fresh material of five Asterina spp. and a related anamorphic stage from Panama, we present the first molecular phylogenetic hypothesis of the Asterinaceae within the Dothideomycetes. A combined SSU and LSU rDNA phylogenetic analysis shows that species of Asterina and its anamorphs form a well supported monophyletic clade within the Dothideomycetes with Venturiaceae as sistergroup. Three Asterina spp. included in the molecular study are new records for Panama and Central America with new records of host plant species: A. cestricola on Cestrum rugulosum (Solanaceae), A. weinmanniae on Weinmannia pinnata (Cunoniaceae) and A. zanthoxyli on Zanthoxylum scheryi (Rutaceae). A. cestricola and A. weinmanniae are illustrated here for the first time.

Five new species belonging to Hermatomyces (Hermatomycetaceae, Pleosporales) are described based on morphological investigations of specimens collected on rotten twigs and stems of various plants in Panama as well as phylogenetic analyses of sequence data of nuclear ribosomal and protein coding genes (EF1-α, RPB2, β-TUB). The new species are described as: Hermatomyces bifurcatus, H. constrictus, H. megasporus, H. sphaericoides, and H. verrucosus spp. nov. Previously described species such as H. sphaericus and H. tucumanensis were identified among the studied specimens. The new combination, H. reticulatus, is made for Subicularium reticulatum based on examination of the holotype and fresh collections. Hermatomyces subiculosus, originally described from Thailand, is reduced to synonymy with H. reticulatus; H. tectonae is synonymized under H. sphaericus based on morphological and molecular evidence; and H. chiangmaiensis and H. thailandicus are considered later synonyms of H. krabiensis and H. indicus, respectively. The type material of Scyphostroma mirum was found to be conspecific with H. tucumanensis and, therefore, the generic name Hermatomyces should be conserved or protected against the older name Scyphostroma and the binomial H. tucumanensis against S. mirum. Sixteen species of Hermatomyces are recognized, their distinctive characteristics are highlighted in line drawings and a key is provided for their identification. The peculiar morphology and consistent phylogeny of new and previously known Hermatomyces species supports the recognition of the recently introduced monotypic family Hermatomycetaceae as a well delimited monophyletic taxon within the order Pleosporales.
