Abstract Only two Coccoloba -associated xerocomoid boletes with smooth basidiospores are currently known from the Dominican Republic, namely Boletus ruborculus and Xerocomus coccolobae . A multilocus phylogenetic analysis of four gene markers (ITS, LSU, RPB2 , TEF1 ) reveals that B forms an autonomous clade in Boletaceae corresponding to a novel genus, which is introduced here as Tropicoboletus...

Fungal species with a broad distribution may exhibit considerable genetic variation over their geographic ranges. Variation may develop among populations based on geographic isolation, lack of migration, and genetic drift, though this genetic variation may not always be evident when examining phenotypic characters. Fomitopsis pinicola is an abundant saprotrophic fungus found on decaying logs th...

BACKGROUND Predictable control of gene expression is necessary for the rational design and optimization of cell factories. In the yeast Saccharomyces cerevisiae, the promoter is one of the most important tools available for controlling gene expression. However, the complex expression patterns of yeast promoters have not been fully characterised and compared on different carbon sources (glucose,...

Following the abolishment of dual nomenclature, Stilbospora is recognised as having priority over Prosthecium. The type species of Stilbospora, S. macrosperma, is the correct name for P. ellipsosporum, the type species of Prosthecium. The closely related genus Stegonsporium is maintained as distinct from Stilbospora based on molecular phylogeny, morphology and host range. Stilbospora longicornu...

Specimens of Paxillus cuprinus, a species recently described from P. involutus complex and characterized by less massive, dully coloured basidiomes with more slender stipes, as well longer basidiospores, were collected authors during an expedition to the Southern Urals (Republic Bashkortostan). The studied collection represents first record in Russia based on basidiomes. identity was confirmed ...

In this study we reassess the taxonomic reference of the previously described holomorphic alkaliphilic fungus Heleococcum alkalinum isolated from soda soils in Russia, Mongolia and Tanzania. We show that it is not an actual member of the genus Heleococcum (order Hypocreales) as stated before and should, therefore, be excluded from it and renamed. Multi-locus gene phylogeny analyses (based on nu...

Armillaria altimontana, previously considered North American biological species (NABS) X, is described as new. To date, it appears that A. altimontana prefers higher-elevation, mesic sites within the dry, conifer forest zone of western interior North America. This species has been found on hardwoods and conifers and is associated most commonly with Abies-dominated forest types in southern Briti...

The generic and sub-generic relationships in the Boletineae (Boletales) were studied using nuclear large subunit (nuc-lsu), translation elongation factor 1-alpha (tef1), and DNA directed RNA polymerase largest subunit (RPB1). The Boletineae, with the exclusion of Hydnomerulius pinastri, was strongly supported and the status of the families Boletaceae and Paxillaceae is discussed. Members of the...

Atheliales (Agaricomycetes, Basidiomycota) is an order mostly composed of corticioid fungi, containing roughly 100 described species in 20 genera. Members exhibit remarkable ecological diversity, including saprotrophs, ectomycorrhizal symbionts, facultative parasites plants or lichens, and symbionts termites. Ectomycorrhizal members are well known because they often form a major part boreal tem...

Abstract Taxonomy of Basidiodendron caesiocinereum complex is revised based on morphological and molecular methods (with the use nc LSU rDNA, ITS TEF1 regions). The basidiospore ornamentation justified as a key character for species recognition in group. As redefined here, B. an angiosperm-dwelling with smooth basidiospores. Bourdotia cinerella var. trachyspora are proved to represent separate ...
