Additions and update to the knowledge of the genus Hysterographium (Ascomycota, Hysteriaceae) in southern South America Darwiniana
Lorenzo,Laura E; Messuti,María I.
The present contribution is the second part of the taxonomic studies about the genus Hysterographium from South America. During the revision of Spegazzini´s type specimens, three valid species (H. andicola, H. australe and H. praeandinum), two doubtful species (H. cumingii and H. cuyanum), and one synonym of H. mori (H. bonaerense) were confirmed. Hysterographium subfuscum is not a valid species. Lectotypes for H. andicola and H. praeandinum were designated. A key to species of Hysterographium recorded from Argentina, Chile and Paraguay is presented.

Asperisporium and Pantospora (Mycosphaerellaceae): epitypifications and phylogenetic placement Naturalis
Minnis, A.M.; Kennedy, A.H.; Grenier, D.B.; Rehner, S.A.; Bischoff, J.F..
The species-rich family Mycosphaerellaceae contains considerable morphological diversity and includes numerous anamorphic genera, many of which are economically important plant pathogens. Recent revisions and phylogenetic research have resulted in taxonomic instability. Ameliorating this problem requires phylogenetic placement of type species of key genera. We present an examination of the type species of the anamorphic Asperisporium and Pantospora. Cultures isolated from recent port interceptions were studied and described, and morphological studies were made of historical and new herbarium specimens. DNA sequence data from the ITS region and n LSU were generated from these type species, analysed phylogenetically, placed into an evolutionary context...

Cymadothea trifolii, an obligate biotrophic leaf parasite of Trifolium, belongs to Mycosphaerellaceae as shown by nuclear ribosomal DNA analyses Naturalis
Simon, U.K.; Groenewald, J.Z.; Crous, P.W..
The ascomycete Cymadothea trifolii, a member of the Dothideomycetes, is unique among obligate biotrophic fungi in its capability to only partially degrade the host cell wall and in forming an astonishingly intricate interaction apparatus (IA) in its own hyphae, while the attacked host plant cell is triggered to produce a membranous bubble opposite the IA. However, no sequence data are currently available for this species. Based on molecular phylogenetic results obtained from complete SSU and partial LSU data, we show that the genus Cymadothea belongs to the Mycosphaerellaceae (Capnodiales, Dothideomycetes). This is the first report of sequences obtained for an obligate biotrophic member of Mycosphaerellaceae.

Dark septate endophytic pleosporalean genera from semiarid areas Naturalis
Knapp, D.G.; Kovács, G.M.; Zajta, E.; Groenwald, J.Z.; Crous, P.W..
Dark septate endophytes (DSE) are distributed worldwide as root-colonising fungi, and frequent in environments with strong abiotic stress. DSE is not a taxon, but constitutes numerous fungal taxa belonging to several orders of Ascomycota. In this study we investigate three unidentified DSE lineages belonging to Pleosporales that were found previously in semiarid sandy grasslands. For molecular phylogenetic studies seven loci (ITS, partial 18S nrRNA, 28S nrRNA, actin, calmodulin, transcription-elongation factor 1-α and ß-tubulin genes) were amplified and sequenced. Based on morphology and the resulting molecular phylogeny these isolates were found to represent three novel genera within the Pleosporales, namely Aquilomyces, Flavomyces and Darksidea, with eight...

Exploring fungal mega-diversity: Pseudocercospora from Brazil Naturalis
Silva, M.; Barreto, R.W.; Pereira, O.L.; Freitas, N.M.; Groenewald, J.Z.; Crous, P.W..
Although the genus Pseudocercospora has a worldwide distribution, it is especially diverse in tropical and subtropical countries. Species of this genus are associated with a wide range of plant species, including several economically relevant hosts. Preliminary studies of cercosporoid fungi from Brazil allocated most taxa to Cercospora, but with the progressive refinement of the taxonomy of cercosporoid fungi, many species were relocated to or described in Pseudocercospora. Initially, species identification relied mostly on morphological features, and thus no cultures were preserved for later phylogenetic comparisons. In this study, a total of 27 Pseudocercospora spp. were collected, cultured, and subjected to a multigene analysis. Four genomic regions...

High diversity and morphological convergence among melanised fungi from rock formations in the Central Mountain System of Spain Naturalis
Ruibal, C.; Platas, G.; Bills, G.F..
Melanised fungi were isolated from rock surfaces in the Central Mountain System of Spain. Two hundred sixty six isolates were recovered from four geologically and topographically distinct sites. Microsatellite-primed PCR techniques were used to group isolates into genotypes assumed to represent species. One hundred and sixty three genotypes were characterised from the four sites. Only five genotypes were common to two or more sites. Morphological and molecular data were used to characterise and identify representative strains, but morphology rarely provided a definitive identification due to the scarce differentiation of the fungal structures or the apparent novelty of the isolates. Vegetative states of fungi prevailed in culture and in many cases could...

Multilocus DNA sequencing of the whiskey fungus reveals a continental‐scale speciation pattern Naturalis
Scott, J.A.; Ewaze, J.O.; Summerbell , R.C.; Arocha-Rosete, Y.; Maharaj, A.; Guardiola, Y.; Saleh, M.; Wong, B.; Bogale, M.; Hara, M.J. O’; Untereiner, W.A..
Baudoinia was described to accommodate a single species, B. compniacensis. Known as the ‘whiskey fungus’, this species is the predominant member of a ubiquitous microbial community known colloquially as ‘warehouse staining’ that develops on outdoor surfaces subject to periodic exposure to ethanolic vapours near distilleries and bakeries. Here we examine 19 strains recovered from environmental samples near industrial settings in North America, South America, the Caribbean, Europe and the Far East. Molecular phylogenetic analysis of a portion of the nucLSU rRNA gene confirms that Baudoinia is a monophyletic lineage within the Teratosphaeriaceae (Capnodiales). Multilocus phylogenetic analysis of nucITS rRNA (ITS1-5.8S-ITS2) and partial nucLSU rRNA,...

New species of Cladosporium associated with human and animal infections Naturalis
Sandoval-Denis, M.; Gené, J.; Sutton, N.P. Wiederhold, J.F. Cano-Lira, J. Guarro, D.A.; Wiederhold , N.P.; Cano-Lira, J.F.; Guarro, J..
Cladosporium is mainly known as a ubiquitous environmental saprobic fungus or plant endophyte, and to date, just a few species have been documented as etiologic agents in vertebrate hosts, including humans. In the present study, 10 new species of the genus were isolated from human and animal clinical specimens from the USA. They are proposed and characterized on the basis of their morphology and a molecular phylogenetic analysis using DNA sequences from three loci (the ITS region of the rDNA, and partial fragments of the translation elongation factor 1-alpha and actin genes). Six of those species belong to the C. cladosporioides species complex, i.e., C. alboflavescens, C. angulosum, C. anthropophilum, C. crousii, C. flavovirens and C. xantochromaticum,...

Phylogeny and taxonomic revision of the Planistromellaceae including its coelomycetous anamorphs: contributions towards a monograph of the genus Kellermania Naturalis
Minnis, A.M.; Kennedy, A.H.; Grenier, D.B.; Palm, M.E.; Rossman, A.Y..
The core species of the family Planistromellaceae are included in the teleomorphic genera Planistroma and Planistromella and the connected anamorphic, coelomycetous genera Alpakesa, Kellermania, and Piptarthron. These genera have been defined primarily on the basis of ascospore septation or number of conidial appendages. Due to a lack of DNA sequence data, phylogenetic placement of these genera within the Dothideomycetes, evaluation of monophyly, and questions about generic boundaries could not be adequately addressed in the past. Isolates of nearly all of the known species in these genera were studied genetically and morphologically. DNA sequence data were generated for the nSSU, ITS, nLSU, and RPB1 markers and analysed phylogenetically. These results...

Resolution of morphology-based taxonomic delusions: Acrocordiella, Basiseptospora, Blogiascospora, Clypeosphaeria, Hymenopleella, Lepteutypa, Pseudapiospora, Requienella, Seiridium and Strickeria Naturalis
Jaklitsch, W.M.; Gardiennet, A.; Voglmayr, H..
Fresh material, type studies and molecular phylogeny were used to clarify phylogenetic relationships of the nine genera Acrocordiella, Blogiascospora, Clypeosphaeria, Hymenopleella, Lepteutypa, Pseudapiospora, Requienella, Seiridium and Strickeria. At first sight, some of these genera do not seem to have much in common, but all were found to belong to the Xylariales, based on their generic types. Thus, the most peculiar finding is the phylogenetic affinity of the genera Acrocordiella, Requienella and Strickeria, which had been classified in the Dothideomycetes or Eurotiomycetes, to the Xylariales. Acrocordiella and Requienella are closely related but distinct genera of the Requienellaceae. Although their ascospores are similar to those of Lepteutypa,...

Two new classes of Ascomycota: Xylobotryomycetes and Candelariomycetes Naturalis
Voglmayr, H.; Fournier, J.; Jaklitsch, W.M..
Phylogenetic analyses of a combined DNA data matrix containing nuclear small and large subunits (nSSU, nLSU) and mitochondrial small subunit (mtSSU) ribosomal RNA and the largest and second largest subunits of the RNA polymerase II (rpb1, rpb2) of representative Pezizomycotina revealed that the enigmatic genera Xylobotryum and Cirrosporium form an isolated, highly supported phylogenetic lineage within Leotiomyceta. Acknowledging their morphological and phylogenetic distinctness, we describe the new class Xylobotryomycetes, containing the new order Xylobotryales with the two new families Xylobotryaceae and Cirrosporiaceae. The two currently accepted species of Xylobotryum, X. andinum and X. portentosum, are described and illustrated by light and scanning...
