Fungal Diversity | Year: 2013

Dothideomycetes comprise a highly diverse range of fungi characterized mainly by asci with two wall layers (bitunicate asci) and often with fissitunicate dehiscence. Many species are saprobes, with many asexual states comprising important plant pathogens. They are also endophytes, epiphytes, fungicolous, lichenized, or lichenicolous fungi. They occur in terrestrial, freshwater and marine habitats in almost every part of the world. We accept 105 families in Dothideomycetes with the new families Anteagloniaceae, Bambusicolaceae, Biatriosporaceae, Lichenoconiaceae, Muyocopronaceae, Paranectriellaceae, Roussoellaceae, Salsugineaceae, Seynesiopeltidaceae and Thyridariaceae introduced in this paper. Each family is provided with a description and notes, including asexual and asexual states, and if more than one genus is included, the type genus is also characterized. Each family is provided with at least one figure-plate, usually illustrating the type genus, a list of accepted genera, including asexual genera, and a key to these genera. A phylogenetic tree based on four gene combined analysis add support for 64 of the families and 22 orders, including the novel orders, Dyfrolomycetales, Lichenoconiales, Lichenotheliales, Monoblastiales, Natipusillales, Phaeotrichales and Strigulales. The paper is expected to provide a working document on Dothideomycetes which can be modified as new data comes to light. It is hoped that by illustrating types we provide stimulation and interest so that more work is carried out in this remarkable group of fungi. © 2013 Mushroom Research Foundation.

Article 59.1, of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code), which addresses the nomenclature of pleomorphic fungi, became effective from 30 July 2011. Since that date, each fungal species can have one nomenclaturally correct name in a particular classification. All other previously used names for this species will be considered as synonyms. The older generic epithet takes priority over the younger name. Any widely used younger names proposed for use, must comply with Art. 57.2 and their usage should be approved by the Nomenclature Committee for Fungi (NCF). In this paper, we list all genera currently accepted by us in Dothideomycetes (belonging to 23 orders and 110 families), including pleomorphic and non-pleomorphic genera. In the case of pleomorphic genera, we follow the rulings of the current ICN and propose single generic names for future usage. The taxonomic placements of 1261 genera are listed as an outline. Protected names and suppressed names for 34 pleomorphic genera are listed separately. Notes and justifications are provided for possible proposed names after the list of genera. Notes are also provided on recent advances in our understanding of asexual and sexual morph linkages in Dothideomycetes. A phylogenetic tree based on four gene analyses supported 23 orders and 75 families, while 35 families still lack molecular data. © 2014, School of Science.

Scolicosporium minkeviciusii, was newly collected in Italy, and subjected to morpho-molecular analyses. Morphological characters clearly indicate that this species is a coelomycete. Combined maximum-likelihood and maximum-parsimony analyses of LSU and SSU gene sequence data of S. minkeviciusii grouped it in Phaeosphaeriaceae with Phaeosphaeria nodorum, P. oryzcie and Stagonospora foliicola, although the type species of Scolicosporium, S. macrosporium, which has not been sequenced, is considered to belong in the family Pleomassariaceae. In this study, we designate an epitype for Scolicosporium minkeviciusii. The placement of S. macrosporium and Scolicosporium sensu stricto remains uncertain and further morpho-molecular studies are necessary to confirm the taxonomic placement of this type species and to delimit this genus. © 2013 Adac.

An experiment was conducted to determine how photosynthesis was affected in Zizania latifolia Turcz. plants by infection of the endophytic smut fungus Ustilago esculenta. The results showed that U.esculenta infection induced a decreased plant height, but significantly increased above-ground biomass production as compared to control plants. Infected plants also exhibited higher Pn and chlorophyll content. In U.esculenta mycelia-sporidial infected plants, Pn, Gs and E generally were higher than those in sporidial infected plants. Compared to control plants, infected plants showed a higher light saturation point (LSP), apparent quantum yield (AQY) but a lower light compensation point (LCP). All leaves at different positions in infected plants showed higher Pn than control plants. The highest Pn was observed in the 4th leaf of infected plants, while it was the 3rd leaf in control plants. Infected plants generally showed relatively higher chlorophyll a fluorescence parameters in ΦPSII, ETR and qP than control plants. Maximum carboxylation rate of Rubisco (Vc, max) and maximum rate of RuBP regeneration (Jmax) were also elevated during U.esculenta infection. Our results revealed that promotion of photosynthetic efficiency was therefore probably mainly due to effects on non-stomatal processes by U.esculenta infection. © 2013 Elsevier Ltd.

The order Meliolales comprises the families Armatellaceae and Meliolaceae. These are black mildews that grow on the surface of host plants, often regarded as minor plant pathogens. In this study, types or specimens of 17 genera of Armatellaceae and Meliolaceae were borrowed from herbaria and re-examined. Armatella is accepted in Armatellaceae and Amazonia, Appendiculella, Asteridiella, Cryptomeliola, Endomeliola, Irenopsis and Meliola are accepted in the family Meliolaceae. Laeviomeliola is synonymized under Meliola. Ceratospermopsis, Ectendomeliola, Haraea, Hypasteridium, Leptascospora, Metasteridium, Ophiociliomyces, Ophioirenina, Ophiomeliola, Parasteridium, Pauahia, Pleomeliola, Pleomerium, Prataprajella, Ticomyces, Urupe and Xenostigme are excluded from Meliolaceae, and are treated as doubtful genera or placed in ascomycetes genera incertae sedis. The type species of each genus is re-described and illustrated with photomicrographs. Notes are provided and comparisons made. Two new species of Meliola and one new species of Irenopsis are also introduced with molecular data and we provide the most populated phylogenetic tree of Meliolomycetidae to date. Meliola thailandicum was found on Dimocarpus longan (Sapindales) and Acacia auriculiformis (Fabales) and confirmed to be the same species in the molecular analyses. This has important implications as the several hundred Meliola species are recognized based on host associations. Thus the same species being recorded from two unrelated hosts sheds doubt on Meliola species being host-specific. © 2015, School of Science.

Dothideomycetes with muriform ascospores, were previously placed in family Pleosporaceae, but they are not a monophyletic group, and can be placed across a range of orders and families. In this study an interesting saprobic ascomycete was isolated from Clematis vitalba which was collected in Italy. The species has unique characters and we introduced the taxon as a new genus and species within Lentitheciaceae, The conclusions are drawn from morphology and, LSU, SSU, EF1-α and RPB2 combined sequence analyses. Maximum parsimony (MP), maximum likelihood (ML) and Mr Bayes phylogenetic analysis all support this being a distinct genus within the Lentitheciaceae. It is distinguished from other genera of this family in having muriform ascospores whose central cells have longitudinal septa and light end cells, and ascomata with a thick peridium and a short neck. The new genus is compared with similar genera in the Lentitheciaceae and a comprehensive description, and micrographs are provided. The cultures were obtained via single ascospore isolation, and the asexual state was also established. © 2014 Adac. Tous droits réservés.

The order Asterinales comprises a single family, Asterinaceae. In this study, types or specimens of 41 genera of Asterinaceae are re-examined and re-described and illustrated by micrographs. Seventeen genera, namely Asterina (type genus), Asterinella, Asterotexis, Batistinula, Cirsosia, Echidnodella, Halbania, Lembosia, Meliolaster, Parasterinopsis, Platypeltella, Prillieuxina, Schenckiella (=Allothyrium), Trichasterina, Trichopeltospora, Uleothyrium and Vizellopsis, are maintained within Asterinaceae. Echidnodes, Lembosiella, Lembosina, Morenoina, and Thyriopsis are transferred to Aulographaceae based on morphological and molecular characteristics. Anariste is transferred to Micropeltidaceae, while Lembosiopsis is transferred to Mycosphaerellaceae. Placoasterella and Placosoma are morphologically close to taxa in Parmulariaceae, where they are transferred. Aulographina is placed in Teratosphaeriaceae, while Asterodothis, Asterinema, Dothidasteromella, Leveillella, Petrakina and Stephanotheca are transferred to Dothideomycetes, genera incertae sedis. Eupelte, Macowaniella, Maheshwaramyces, Parasterinella, and Vishnumyces are treated as doubtful genera, because of lack of morphological and molecular data. Aphanopeltis, Asterolibertia, Neostomella, Placoasterina, and Symphaster are synonyms of Asterina based on morphology, while Trichamelia, Viegasia, and Yamamotoa are synonyms of Lembosia. The characteristics of each family are discussed and a phylogenetic tree is included. © 2014, School of Science.

The type specimens or representative specimens of the potentially dothidealean genera Bagnisiella, Botryochora, Coccostromella, Columnosphaeria, Delphinella, Dictyodothis, Discosphaerina, Dothidea, Dothiora, Endodothiora, Jaffuela, Mycoporis, Omphalospora, Pachysacca, Plowrightia, Saccothecium, Stylodothis, Sydowia and Yoshinagaia were examined while, fresh specimens of Aureobasidium pullulans, Dothidea insculpta, Plowrightia ribesia and Saccothecium sepincola were made from Italy and Thailand. An introduction and the history of these genera, their family placement, morphology, and molecular phylogeny are provided. Morphology plus GenBank data are used to provide a systematic treatment of Dothideales. Phylogenetic analysis of LSU, SSU and ITS gene regions was carried out and in the resulting phylogenetic tree the taxa cluster in two clades with high bootstrap support. Clade A comprises Dothideaceae, the family type of Dothideales. The family Dothioraceae is not recognized as a distinct family and is synonymized under Dothideaceae. Neocylindroseptoria is introduced to accommodate Cylindroseptoria pistaciae as it forms a well-supported distinct clade in Dothideaceae. Clade B comprises Aureobasidium, Kabatiella, Pseudoseptoria, Saccothecium and Selenophoma species and Columnosphaeria fagi, for which we propose a new family, Aureobasidiaceae. The recently introduced Sydowia eucalypti also clustered within Clade B and therefore based on morphology and molecular phylogeny a new genus Pseudosydowia is introduced for Sydowia eucalypti. Celosporium laricicola is separated in a distinct clade, and therefore it is placed in Dothideales, genera, incertae sedis. The genera Bagnisiella, Botryochora, Coccostromella, Jaffuela, Lucidascocarpa, Mycoporis, Omphalospora, Pachysacca and Yoshinagaia are excluded from Dothideales and their placements are discussed. © 2014, School of Science.
