Zeloasperisporiales Hongsanan & K.D. Hyde.
MycoBank number: MB 551336; Index Fungorum number: IF 551336; Facesoffungi number: FoF 551336.
The order was established by Hongsanan et al. (2015b) to accommodate Zeloasperisporiaceae. Previous phylogenetic analyses using LSU and SSU sequence data indicated that this order is a distinct lineage from Microthyriales within Dothideomycetes, and formed as a sister clade to freshwater order Natipusillales. Morphologically, this order is very different from Natipusillales. Therefore, the order status of Zeloasperisporiales is strongly supported by both phylogeny and morphology (Figs. 93 and 94). The divergence time for Zeloasperisporiales is estimated as 180 MYA (stem age, Hongsanan et al. 2020).
Accepted families: Zeloasperisporiaceae.
Fig. 93 Phylogram generated from maximum likelihood analysis (RAxML) of genera in Zeloasperisporiales based on LSU and SSU sequence data. Maximum likelihood bootstrap values equal or above 70%, Bayesian posterior probabilities equal or above 0.90 (MLBS/ PP) are given at the nodes. An original isolate number is noted after the species name. The tree is rooted to Venturia inaequalis (CBS 594.70, CBS 815.69). The ex-type strains are indicated in bold. Hyphen (-) represents support values below 70% MLBS and 0.90 PP
