Mycosphere notes 51-101. Revision of genera in Perisporiopsidaceae and Pseudoperisporiaceae and other Ascomycota genera incertae sedis

Abstract

This is the second in a series, Mycosphere notes, wherein we provide notes on various fungal genera. In this set of notes we deal with genera of the families Perisporiopsidaceae and Pseudoperisporiaceae. These families have traditionally accommodated taxa associated with dead and living leaves of mostly tropical plants and comprised pathogens, saprobes or epiphytes. Most genera are poorly understood with only brief Latin descriptions, but molecular sequence data are needed to establish their taxonomic placements. In this study, 50 genera and 51 taxa are reexamined and their placements at the family level discussed. Thirteen new families Alinaceae, Balladynaceae, Cleistosphaeraceae, Dysrhynchisceae, Hyalomeliolinaceae, Lizoniaceae, Nematotheciaceae, Neoparodiaceae, Phaeodimeriellaceae, Pododimeriaceae, Polyclypeolinaceae, Stomatogeneceae and Toroaceae are introduced and Dimeriaceae is reinstated in this paper. One new species, Phaeostigme alchorneae is introduced. Nine genera are transferred to other families. However, fresh collections, epitypification or reference specimens including DNA sequence data, are required to confirm their phylogenetic placements.

Refined families of Dothideomycetes: orders and families incertae sedis in Dothideomycetes

“…Alina is similar to Tretospora (the asexual morph of Balladynopsis) based on some hyphomycetous conidial structures found on the ex-isotype of Alina jasmini (Sivanesan 1981). By re-examining the same specimen, Boonmee et al (2017) reported that they were unable to find some structures e.g. setae, hyphopodia-like structures or even conidia as previously shown in Raciborski (1909) and Sivanesan (1981).…”

“…setae, hyphopodia-like structures or even conidia as previously shown in Raciborski (1909) and Sivanesan (1981). They concluded that Alina has unique characters and could not be placed in any families in Dothideomycetes (Boonmee et al 2017). Thus, they established Alinaceae to accommodate this genus.…”

“…Type: Coccoidea Henn. Notes: Coccoideaceae includes Coccoidea, Coccoidella and Englerodothis, and is treated in Dothideomycetes as family incertae sedis (Hyde et al 2013;Boonmee et al 2017;Wijayawardene et al 2018;Pem et al 2019c). The characteristic feature of the family is ascostromata which are formed as circular to discoid or cushion-like with dark pigment, which is rather unique of its members.…”

“…The characteristic feature of the family is ascostromata which are formed as circular to discoid or cushion-like with dark pigment, which is rather unique of its members. Boonmee et al (2017) revisited Coccoidella and provided a description and illustration of type species C. scutula and accepted this genus in Coccoideaceae. Pem et al (2019c) included Englerodothis in Coccoideaceae.…”
