Blastacervulus H.J. Swart, Trans. Br. mycol. Soc. 90(2): 289 (1988).
MycoBank number: MB 11029; Index Fungorum number: IF 11029; Facesoffungi number: FoF 06733; – 4 morphological species (Species Fungo rum 2020), 3 species with molecular data.
Type species: Blastacervulus eucalypti H.J. Swart, Trans. Br. mycol. Soc. 90(2): 289 (1988).
Notes: Blastacervulus is a coelomycetous genus characterised by acervular conidiomata and thallic, 1-septate conidia with truncate, flat hila. Wijayawardene et al. (2016) showed that B. eucalypti clustered in Planistromellaceae, however, it forms within the Thyrinulaceae in our analyses (Fig. 5).
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 support values less than 70% MLBS and 0.90 PP
