Dothistroma needle blight is one of the most severe needle diseases of pines caused by two closely related species, Dothistroma septosporum and D. pini. The further spread and distribution of this disease were investigated in Slovakia, and new hosts and stand types were identified at the regional level. Dothistroma septosporum was recorded in a nat...

Lophodermium species are well known to be among the dominant endophytic fungi colonizing pine needles. The occurrence of two species with different life strategies on different Pinus trees across Slovakia was detected by PCR using species-specific primers. In general, the commensalistic species L. pinastri was more frequent than parasitic L. sediti...

Russula subgenus Compactae is a group of ectomycorrhizal basidiomycetes, usually with large pileate fruitbodies. European members of the group are characterised by the absence of bright colours on the surfaces of their pilei, the context turning grey to black after cutting, the abundance of short lamellulae in the hymenophore, and spores with an in...

Crepidotus applanatus is known as a common wood inhabiting fungus widely distributed throughout the Northern Hemisphere. There have been contrasting opinions about the delimitation and taxonomic treatment of the similar species C. malachius. Our phylogeny did not support the close relationship of these two morphologically similar species and the gr...

The Roseinae clade is a lineage of the genus Russula primarily composed of species of Russula subsect. Roseinae. Species in this morphologically distinct clade possess a white to pale cream spore print, mild taste, positive reaction to sulfovanillin, and primordial hyphae with acid-resistant crystals in the pileipellis. Here, we present a morpholog...

Phylogenetic reconstruction of Hodophilus species with a yellow colour on the stipe based on nrITS, nrLSU and rpb2 sequences revealed six European species. All these species correspond to the widely accepted European concept of a single species Hodophilus micaceus. Four of these species are described and illustrated. H. micaceus and H. phaeoxanthus...

Dothistroma needle blight (DNB) has been observed in Slovakia during the last two decades. Up until 2017, Dothistroma septosporum has only been detected and molecularly confirmed to cause DNB in Slovakia. Here, we report the detection of Dothistroma pini at six localities around Slovakia, representing different plantation types. Four pine species (...

Among 45 Russula species and infraspecific taxa described by J. Blum, only few are currently accepted. Here we present a case study on R. formosa nom. illeg. (homotypic synonym of R. blumiana), R. decipiens var. ochrospora nom. inval. and R. roseobrunnea. The study is based on sequences and morphological observations of authentic herbarium material...

Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to am...

In this paper, the authors present modern microscopical studies for 28 type specimens of Russula species described by C.H. Peck, thereby completing the revision of all 44 Russula taxa described by this author and for which type specimens were available. Our results suggest that with eventual exception of R. granulata var. lepiotoides (a likely syno...

Crepidotus stenocystis and C. brunnescens are morphologically similar species defined by globose to subglobose spores, the presence of clamp connections in all tissues and bottle-like or flask-like cheilocystidia. They are also similar in the pileal aspect which is hygrophanous, glabrous or white-fibrillose, at first white but becoming brownish wit...

Hodophilus atropunctus is traditionally defined as the only species of this genus with dark brown or black dots on the stipe. Multi-locus phylogenetic reconstruction recognised two distinct clades morphologically corresponding to this species concept. The limited morphological description in the protologue of H. atropunctus and absence of a type sp...

Russula is one of the most speciose genera of mushroom-forming fungi, but phylogenetic relationships among species and subgeneric groupings are poorly understood. Our multi-locus phylogenetic reconstruction places R. firmula, R. rubra, R. rutila and R. veternosa in a well-supported Rubrinae clade, belonging to the Integrae clade of the Crown clade...

Four European Hodophilus species with an odour similar to naphthalene, a strong unpleasant odour similar to that of mothballs, are recognized based on sequence and/or morphological data. The traditional concept defines Ho. foetens as the only Hodophilus species with a naphthalene odour in Europe. This name is now assigned to one of the studied spec...

Five North American Hodophilus species with naphthalene-like odours are now recognized based on sequence and (or) morphological data and molecular annotation of type collections. Two well-supported eastern North American species do not match any of the studied types and are described here as new: Hodophilus hesleri and Hodophilus smithii. The previ...

The current generally accepted concept of Russula maculata defines the species by yellow-brownish spots on the basidi-omata, an acrid taste, a yellow spore print and a red pileus. This concept was tested using collections originating from various geographical areas mainly in Europe. Analyses of the ITS region suggested that there were three species...

The genus Camarophyllopsis contains species with lamellate (agaricoid) basidiomes in the family Clavariaceae (Agaricales), a group otherwise dominated by club-like (clavarioid) or branched (coralloid) forms. Previous studies have suggested that species classified in Camarophyllopsis occur in two independent lineages. We reconstructed a multilocus p...

Species ofRussulasubsect.Xerampelinaeare notoriously difficult to identify and name and have not been subject to molecular study. A group of species, referred to here as theR. clavipescomplex, growing in association withSalix,BetulaandPopulusas well as coniferous tree species from temperate to arctic and alpine habitats, were examined. Analyses of...
