The Russulales is one of 12 major lineages recently elucidated by molecular sequence data in the homobasidiomycetes. [] Key Result Two large sister groups encompassing 11-13 major clades have been recovered within the Russulales. Based on molecular and morphological data 12 families and approximately 80 genera have been identified, although placement of many taxa has not yet been determined.

A multi-gene phylogeny of Lactifluus (Basidiomycota, Russulales) translated into a new infrageneric classification of the genus

An extensive dataset of the genetically diverse milkcap genus Lactifluus is assembled, comprising 80 % of all known species and 30 % of the type collections, and shows that the five featured characteristics are important at different evolutionary levels, but further characteristics need to be studied to find morphological support for each clade.

Four new species of sequestrate Inocybe from Chilean Nothofagaceae forests

Results of the phylogenetic analysis resolved the four new species of Inocybe as distinct species-level clades with strong support, suggesting that these fungi have convergently evolved sequestrate forms independently.

Two new species of Russula (Russulales) from India

Two species: Russula shingbaensis and R. thindii are proposed here as new to science based on their morphological features and ITS-based phylogenetic tree and their relationship with allied taxa are discussed in the present paper.

Ectomycorrhizal iconoclasts: the ITS rDNA diversity and nitrophilic tendencies of fetid Russula

A phylogenetic analysis of ITS rDNA sequences and a meta-analysis of studies that examine ectomycorrhizal fungi response to nitrogen increase show that nitrophilic tendencies appear throughout fetid Russulas suggesting that this character is not an isolated trait within this subgenus but instead is a more general feature of the group overall.

Two new taxa of the Auriscalpium vulgare species complex with substrate preferences

Three species, having distinct substrate preferences, are documented here, namely the well-known A. vulgare, and the newly described species A. orientale and A. microsporum, which are known mainly from subtropical East Asia and northeastern India to date.

Mystery unveiled: Diacanthodes Singer – a lineage within the core polyporoid clade

This study revealed Diacanthodes as a member of the ‘core polyporoid’ clade within the Polyporales, and two new species from South America and Africa are revealed.

Comprehensive taxon sampling reveals unaccounted diversity and morphological plasticity in a group of dimitic polypores (Polyporales, Basidiomycota)

The phylogeny of the poroid and hydnoid genera Antrodiella, Junghuhnia, and Steccherinum was studied utilizing sequences of the gene regions ITS, nLSU, mtSSU, atp6, rpb2, and tef1 to show that most species of these genera form a well supported clade in the Polyporales.

Characterization and identification of Russula firmula and Russula postiana from Himalayan moist temperate forests of Kashmir

Two ectomycorrhizal species of genus Russula: Russula postiana and Russula firmula have been characterized and identified from Kashmir Himalaya using morpho-anatomical and molecular methods targeting its rDNA, and both species distinctly clustered with their respective groups.

Biodiversity and molecular ecology of Russula and Lactarius in Alaska based on soil and sporocarp DNA sequences

The results demonstrate high diversity and strong ecological partitioning in two important ectomycorrhizal genera within a relatively small geographic region, but with implications to the expansive boreal forests.



Phylogenetic relationships of russuloid basidiomycetes with emphasis on aphyllophoralean taxa

Phylogenetic relationships among russuloid basidiomycetes were investigated using sequence data from the nuclear 5.8S, ITS2 and large-subunit rDNA genes and results suggest that gloeocystidia are a synapomorphy for taxa within the rRussuloid clade while the amyloidity of spores is inconsistent.

Molecular phylogeny of the genus Russula in Europe with a comparison of modern infrageneric classifications

Mapping of characters such as spore print colour, taste, and presence of acid resistant incrustations, which have been used to define infrageneric taxa in Russula, onto the phylogeny identified interesting patterns consistent with hypotheses regarding plesiomorphic and apomorphic characters.

High phylogenetic diversity among corticioid homobasidiomycetes.

It is concluded that corticioid fungi hold a considerable share of the phylogenetic diversity displayed by homobasidiomycetes, and should always be considered when phylogenetic studies of larger basidiomyCetes are designed.

A molecular phylogeny of the Russulales including agaricoid, gasteroid and pleurotoid taxa

Analysis of the n-LSU region suggested that synonomy of gasteroid genera into Russula and Lactarius is justifiable, and agaricoid and hypogeous gasteroids genera appear to be polyphyletic.

Systematics of pleurotoid Russulaceae from Guyana and Japan, with notes on their ectomycorrhizal status.

Three species of pleurotoid, putatively lig- nicolous basidiomycetes previously described in the genus Lactarius sect Panuoidei were redescribed from fresh material collected in Guyana and Japan, confirming that these fungi are ectomycorrhizal and that their fruiting habit on organic deposits and well rotted wood at elevated positions is not due to sap- rotrophy, as previously assumed.

A sequence database for the identification of ectomycorrhizal basidiomycetes by phylogenetic analysis

A sequence database for 80 genera of Basidiomycota from the Hymenomycete lineage for a small region of the mitochondrial large subunit rRNA gene is assembled, and two interesting patterns emerge: the switch between ectomycorrhizae and saprobic lifestyles appears to have happened convergently several and perhaps many times.

Higher-level phylogenetic relationships of Homobasidiomycetes (mushroom-forming fungi) inferred from four rDNA regions.

Parsimony and maximum-likelihood analyses support the monophyly of the eight major clades recognized by Hibbett and Thorn, and most groups are strongly supported in bootstrapped parsimony analyses, but the polyporoid clade remains weakly supported.

Progress toward a phylogenetic classification of the Polyporaceae through parsimony analysis of mitochondrial ribosomal DNA sequences

Seven groups of species are generally well supported (as measured by bootstrapping) or are congruent with previous taxonomic hypotheses, and Parsimony analyses of these sequences suggest that the Polyporaceae are polyphyletic.

Small genets of Lactarius xanthogalactus, Russula cremoricolor and Amanita francheti in late‐stage ectomycorrhizal successions

The results suggest that spore propagation plays a much more important role in the life history of the Russulaceae in undisturbed forest settings than previously recognized.

The phylogenetic distribution of resupinate forms across the major clades of mushroom‐forming fungi (Homobasidiomycetes)

Phylogenetic relationships of resupinate Homobasidiomycetes (Corticiaceae s. lat. and others) were studied using ribosomal DNA sequences from a broad sample of res upinate and nonresupinate taxa to support monophyly of the eight major clades of Homob as well as independent lineages corresponding to the Gloeophyllum clade, corticioid clade and Jaapia argillacea.
