“…Barreto) were reported on ferns (Polypodiaceae J. Presl & C. Presl) (Guatimosim et al 2014a). Inocyclus angularis has conidiomata intermixed with the ascomata, occupying the same stromata located in the central region of the colonies and hyaline, aseptate, fusiform to clavate conidia reported by Guatimosim et al (2014a). However, the asexual morph of generic type is undetermined.…”

The family Parmulariaceae comprises three polyphyletic genera, but with very little data in GenBank and is presently placed in the order Asterinales. In this study, we re-analyze the available sequence data for taxa of the family and re-examine the type species of Hemigrapha, Inocyclus and Parmularia. The phylogenetic tree generated from maximum likelihood and Bayesian analyses of combined LSU-SSU sequence data demonstrate the relationships among Hemigrapha, Inocyclus and Parmularia species, and the relations of Buelliella, Karschia, Labrocarpon, Lembosia, Melaspileella, Melaspileopsis and Stictographa. We introduce Parmulariales ord. nov. to accommodate Parmulariaceae and the order Asterinales accommodates Asterinaceae, Asterotexaceae, Hemigraphaceae fam. nov., Melaspileellaceae fam. nov. and Stictographaceae fam. nov. Notes for each new order and families are provided. We confirm that Asterinaceae sensu lato is distant from Asterinaceae sensu stricto in the phylogenic analysis. The classification presented here is provisional, as more species are needed to re-collected and sequenced. We expect further support for our ordinal and familial lineages, as well as further novel lineages.

“…Early results of the survey for plant pathogenic fungi occurring on ferns in Brazil indicated a plethora of novel taxa to exist in this niche. Two of the preliminary findings, namely two taxa in the Parmulariaceae , have already been published: the new genus Rhagadolobiopsis ( Guatimosim et al 2014a ) and the new species Inocyclus angularis ( Guatimosim et al 2014b ). Similarly, another research group in Asia has been studying fungi on ferns and have recently described the new species Venustosynnema reniformisporum and Zasmidium dicranopteridis ( Kirschner & Liu 2014 ).…”

The fern flora of the world (Pteridophyta) has direct evolutionary links with the earliest vascular plants that appeared in the late Devonian. Knowing the mycobiota associated to this group of plants is critical for a full understanding of the Fungi. Nevertheless, perhaps because of the minor economic significance of ferns, this niche remains relatively neglected by mycologists. Cercosporoid fungi represent a large assemblage of fungi belonging to the Mycosphaerellaceae and Teratosphaeriaceae (Ascomycota) having cercospora-like asexual morphs. They are well-known pathogens of many important crops, occurring on a wide host range. Here, the results of a taxonomic study of cercosporoid fungi collected on ferns in Brazil are presented. Specimens were obtained from most Brazilian regions and collected over a 7-yr period (2009–2015). Forty-three isolates of cercosporoid and mycosphaerella-like species, collected from 18 host species, representing 201 localities, were studied. This resulted in a total of 21 frond-spotting taxa, which were identified based on morphology, ecology and sequence data of five genomic loci (actin, calmodulin, ITS, LSU and partial translation elongation factor 1-α). One novel genus (Clypeosphaerella) and 15 novel species (Cercospora samambaiae, Clypeosphaerella sticheri, Neoceratosperma alsophilae, N. cyatheae, Paramycosphaerella blechni, Pa. cyatheae, Pa. dicranopteridis-flexuosae, Pa. sticheri, Phaeophleospora pteridivora, Pseudocercospora brackenicola, Ps. paranaensis, Ps. serpocaulonicola, Ps. trichogena, Xenomycosphaerella diplazii and Zasmidium cyatheae) are introduced. Furthermore, 11 new combinations (Clypeosphaerella quasiparkii, Neoceratosperma yunnanensis, Paramycosphaerella aerohyalinosporum, Pa. dicranopteridis, Pa. gleicheniae, Pa. irregularis, Pa. madeirensis, Pa. nabiacense, Pa. parkii, Pa. pseudomarksii and Pa. vietnamensis) are proposed. Finally, nine new host associations are recorded for the following known fungal species: Cercospora coniogrammes, Cercospora sp. Q, Ps. abacopteridicola, Ps. lygodiicola and Ps. thelypteridis.

“…The latest publication mentioning this family (Hyde et al 2013) added Antoniomyces and excluded four genera ( Coccodothis , Dothidasteroma , Englerodothis and Perischizon ) from the Parmulariaceae based on the shape of the ascomata, reducing the total number to 31 genera. Now, with the addition of the recently described genus Rhagadolobiopsis ( Guatimosim et al 2014a ), the Parmulariaceae include 32 genera and 114 synonyms ( Inácio & Cannon 2008 , Lumbsch & Huhndorf 2010 , Inácio et al 2012b , Hyde et al 2013 , Guatimosim et al 2014a , b ).…”

Towards a phylogenetic reappraisal of Parmulariaceae and Asterinaceae (Dothideomycetes)

et al. 2015

Members of the Asterinaceae and Parmulariaceae are obligate biotrophic fungi with a pantropical distribution that grow in direct association with living plant tissues and produce external ascomata and bitunicate asci. These fungi are poorly known, with limited information about their taxonomic position in the Dothideomycetes. Much of what is known is conjectural and based on observation of morphological characters. An assessment of the phylogenetic position of the Asterinaceae and Parmulariaceae is provided based on a phylogenetic analysis of the nrDNA operon (ITS) and the large subunit rDNA (LSU) sequence data obtained from fresh material of selected species collected in Brazil. Three key species were included and epitypified, namely Asterina melastomatis, which is the type species for the type genus of the Asterinaceae; Prillieuxina baccharidincola (Asterinaceae); and Parmularia styracis, which is the type species for the type genus of the Parmulariaceae. An LSU rDNA phylogenetic analysis was performed indicating the correct phylogenetic placement of the Asterinales within the Dothideomycetes. From this initial analysis it is clear that the Parmulariaceae as currently circumscribed is polyphyletic, and that the Asterinaceae and Parmulariaceae are related, which justifies the maintenance of the order Asterinales. Asterotexis cucurbitacearum is recognised as distinct from other Dothideomycetes and placed in the newly proposed family and order (Asterotexiaceae, Asterotexiales), while the higher order phylogeny of Inocyclus angularis remains unresolved. Additionally, Lembosia abaxialis is introduced as a novel species and the phylogenetic placement of the genera Batistinula and Prillieuxina is clarified.
