R. levyana, R. floridana and R. praerubriceps are three species described by W.A. Murrill that are traditionally interpreted as synonyms of R. xerampelina var. semirubra Singer. As such, these species have never been reported again since their original description. In this paper the authors re-examine and illustrate the type-specimens of these spec...

Cantharellus quercophilus. is described and illustrated from a post-oak savannah in Texas, USA. Morphological differences with other, small yellowish brown American Cantharellus species are discussed, mainly C.tabernensis, C.appalachiensis, C.septentrionalis and C.minor. The type specimens for all these Cantharellus have been reexamined to verify t...

Guidelines are provided for collecting a group of organisms that has often been overlooked in earlier inventories: the kingdom Fungi and other groups that are traditionally collected by mycologists such as slime molds. After a short introduction on fungi and the feasibility of an 'all fungal taxa' inventory, the authors divide the fungi in six 'pra...

Formal proposals to conserve or protect fungal names as well as proposals to amend the International Code of Nomenclature of immediate interest to mycologists are now published concurrently in Mycotaxon and Taxon. Conservation proposals include Prop. 1918 (to conserve the name Dermatocarpon bucekii against Placidium steineri), Prop. 1919 (to conser...

Aim The ectomycorrhizal (ECM) mushroom family Inocybaceae is widespread in north temperate regions, but more than 150 species are encountered in the tropics and the Southern Hemisphere. The relative roles of recent and ancient biogeographical processes, relationships with plant hosts, and the timing of divergences that have shaped the current geogr...

Russula texensis sp. nov. is described from Newton Co, Texas, as a new typical member of sect. Xerampelinae. It is a very rare species that can be defined by the combination of characters of spores and those of hyphal terminations and dermatocystidia in the pileus.

Cantharellus fistulosus sp. nov from Tanzania is described as a close relative to C. schmitzii from tropical miombo woodland dominated by tree species in Brachystegia, Julbernardia and Isoberlinia. The species is characterised by having a hollow, smooth stipe and a pink hymenium that contrasts with the yellowish brown stipe and cap surface.

GenBank, the public repository for nucleotide and protein sequences, is a critical resource for molecular biology, evolutionary biology, and ecology. While some attention has been drawn to sequence errors ([1][1]), common annotation errors also reduce the value of this database. In fact, for

This paper questions the validity of the traditional features used to delimit genera in the order Russulales. Molecular phylogenetic analyses of ribosomal genes (ITS-nucLSU) and part of a protein-coding gene (RPB2) indicate that four phylogenetically distinct clades are identified within Russulaceae. In the light of molecular and morphological evid...

Cantharellus conspicuus sp. nov. is described from collections made in Zimbabwean woodlands (Central Africa) and is also reported from Benin. This taxon is well characterised by its resemblance to some species of Craterellus.

Species in the large mushroom genus Russula are important ecologically as ectomycorrhizal fungi and economically as comestibles. Most infrageneric classification schemes of this genus have originated in Europe, but because of nomenclatural history and an evolving suite of characters these systems remain largely incongruent. Using ribosomal DNA sequ...
