MycoBank number: MB 3270; Index Fungorum number: IF 3270; Facesoffungi number: FoF 07612, 26 morphological species (Species Fungorum 2020), 2 species with molecular data.
Type species: Morenoina antarctica (Speg.) Theiss.
Notes: Morenoina was placed in Leptopeltidaceae and Asterinaceae (von Arx and Müller 1975; Lumbsch and Huhndorf 2010). Hongsanan et al. (2014b) designated an epitype and placed this genus in Aulographaceae as Morenoina did not have free hyphae with appressoria as other members of Asterinaeceae and it has different ascus form from members of Leptopeltidaceae. Morenoina resembles Aulographum and differs only in the morphology of the scutellum which comprises inordinately arranged cells and a hypostroma of subcuticular hyphae beneath the thyriothecium, which is lacking in Morenoina (Ellis 1980). Phylogenetic placement of Aulographaceae is uncertain due to lack of sequence data. Sequence data of Aulographum hederae (type species) formed an unstable clade, while two species of Morenoina form a distinct clade within Asterinales (Fig. 5). Therefore, we place Morenoina in the new family Morenoinaceae.
Fig. 5 Phylogram generated from maximum likelihood analysis (RAxML) of Asterinales based on LSU sequence data. Maximum likelihood bootstrap values equal to or greater than 70%, Bayesian posterior probabilities equal to or greater than 0.90 (MLBS/PP) are given at the nodes. Isolate numbers are noted after each species name. The tree is rooted to Venturia inaequalis (ATCC 60070) and Venturia populina (CBS 256.38). Newly sequence data generated in this study are in blue. Ex-types are indicated in bold. Hyphen (-) represents sup- port values less than 70% MLBS and 0.90 PP
