The genus Ramularia includes numerous phytopathogenic species, several of which are economically important. Ramularia eucalypti is currently the only species of this genus known to infect Eucalyptus by causing severe leaf-spotting symptoms on this host. However, several isolates identified as R. eucalypti based on morphology and on nrDNA sequence data of the ITS region have recently been isolated from other plant hosts, from environmental samples and also from human clinical specimens. Identification of closely related species based on morphology is often difficult and the ITS region has previously been shown to be unreliable for species level identification in several genera. In this study we aimed to resolve this species-complex by applying a polyphasic...

The genus Melanoleuca (Pat.) Pat. is divided in three subgenera based on the morphology of the cystidia, viz. (i) subgen. Macrocystis, consisting of the sections Alboflavidae, Cognatae and Strictipedes, (ii) subgen. Melanoleuca and (iii) subgen. Urticocystis comprising two sections, viz. Grammopodiae and Humiles. Melanoleuca brevipes, M. cognata, M. exscissa, M. grammopodia, M. melaleuca, M. polioleuca, M. politoinaequalipes, M. rasilis, and M. turrita are redescribed.

Nineteen species of Stereocaulon are treated from the northern Andes, mainly from Colombia. Descriptions and keys are given, with notes on the north-Andean distribution and ecology. Seven species are new for the Colombian flora, viz. St. atlanticum, St. claviceps, St. corticatulum (chem. strain with atranorin and perlatolic acid), St. delisei, St. microcarpum, St. pachycephalum and St. pomiferum. St. crambidiocephalum is reported for the first time from Costa Rica, as is St. didymicum from Venezuela, and St. delisei is reported for the first time from the New World (Colombia and Costa Rica). St. cornutum Müll. Arg. is reduced to synonymy under St. pityrizans Nyl.

The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional to ITS rDNA as primary barcode. Ampliﬁcation efﬁciencies of 14 (partially) universal primer pairs targeting eight genetic markers were tested across > 1 500 species (1 931 strains or specimens) and the outcomes of almost twenty thousand (19 577) polymerase chain reactions were evaluated. We tested several well-known primer pairs that amplify: i) sections of the nuclear ribosomal RNA gene large subunit (D1–D2 domains of 26/28S); ii) the complete internal transcribed spacer region (ITS1/2); iii) partial β-tubulin II (TUB2); iv) γ-actin (ACT); v) translation elongation factor 1-α (TEF1α);...

Boekhout, T.; Bas, C..

The generic separation of Oudemansiella and Xerula is discussed and accepted as proposed by Dörfelt. Xerula caussei and X. kuehneri are redescribed and illustrated. Xerula nigra and X. renatii are considered conspecific with X. caussei. Dactylosporina is reduced to the synonymy of Xerula. The new combinations X. steffenii and X. macracantha are introduced.

Moniliellomycetes and Malasseziomycetes, two new classes in Ustilaginomycotina

Wang, Q.-M.; Theelen, B.; Groenewald, M.; Bai, F.-Y.; Boekhout, T..

Ustilaginomycotina (Basidiomycota, Fungi) has been reclassiﬁed recently based on multiple gene sequence analyses. However, the phylogenetic placement of two yeast-like genera Malassezia and Moniliella in the subphylum remains unclear. Phylogenetic analyses using different algorithms based on the sequences of six genes, including the small subunit (18S) ribosomal DNA (rDNA), the large subunit (26S) rDNA D1/D2 domains, the internal transcribed spacer regions (ITS 1 and 2) including 5.8S rDNA, the two subunits of RNA polymerase II (RPB1 and RPB2) and the translation elongation factor 1-α (EF1-α), were performed to address their phylogenetic positions. Our analyses indicated that Malassezia and Moniliella represented two deeply rooted lineages within...

Characters used in current taxonomy of the genus Volvariella are discussed. Spore dimensions are a good additional character for distinguishing species. Volvariella caesiotincta, V. hypopithys, V. murinella, and V. pusilla are redescribed. Volvariella murinella f. brevispora is described and V. taylori is reduced to a variety of V. pusilla.
