The butter boletes (Boletus s.l. sect. Appendiculati) are an economically important group of ectomycorrhizal fungi whose basidiocarps have a yellow tube layer that often bruises blue, yellow reticulate stipe, mild flavor and firm yellow-tinged flesh that may or may not turn blue when exposed. Morphological characters and molecular data (ITS and LSU) place this group in a separate phylogenetic clade from Boletus sensu stricto. Here we establish a new genus, Butyriboletus, to accommodate 14… 

Cacaoporus, a new Boletaceae genus, with two new species from Thailand

Abstract We introduce a new genus, Cacaoporus, characterised by chocolate brown to dark brown basidiomata and hymenophore, tubes not separable from the pileus context, white to off-white basal

A new genus, Rubroboletus, to accommodate Boletus sinicus and its allies

The phylogenetic analyses based on five gene markers recognized eight species in the genus Rubroboletus, including one new species and seven new combinations, a key to the eight species is provided.

Rubinosporusauriporus gen. et sp. nov. (Boletaceae: Xerocomoideae) from Tropical Forests of Thailand, Producing Unusual Dark Ruby Spore Deposits

The Boletaceae-wide and Xerocomoideae-wide phylogenetic analyses based on four-gene data sets support Rubinosporus as monophyletic and places it in Bolet Families subfamily Xerocomeideae.

Molecular phylogeny of Caloboletus (Boletaceae) and a new species in East Asia

A new species was described and a key to the six species of Caloboletus is provided, characterized by the combination of the yellow hymenophore, smooth spores that are olive-brown in deposit, an interwoven pileipellis and a distinctly bitter taste of the context.

Exploring the Relationships between Four New Species of Boletoid Fungi from Northern China and Their Related Species

Four new species of boletoid fungi are introduced in northern China based on the study of their morphology and phylogeny and the evidence and analyses indicated the new species’ relationships with other species within their genera.

Neoboletusantillanus sp. nov. (Boletaceae), first report of a red-pored bolete from the Dominican Republic and insights on the genus Neoboletus

Three genomic regions have been sequenced in order to reinforce the recognition of the new species and to elucidate its taxonomic affiliation within Neoboletus.

First records of Exsudoporus permagnificus and Pulchroboletus roseoalbidus (Boletales) in association with non-native Fagaceae, with taxonomic remarks

These are the first records of Exsudoporus and Pulchroboletus species with this host-tree and another character for setting apart E. permagnificus from the members of the genus Butyriboletus, an earlier suggested affinity.

Reappraisal of the Genus Exsudoporus (Boletaceae) Worldwide Based on Multi-Gene Phylogeny, Morphology and Biogeography, and Insights on Amoenoboletus

Outcomes from a multilocus phylogenetic analysis clearly resolve Exsudoporus as a monophyletic, homogenous and independent genus that is sister to Butyriboletus.

Indoporus shoreae gen. et sp. nov. (Boletaceae) from Tropical India

Tropical dry deciduous Shorea dominated forests in Jharkhand (India) harbour diverse groups of ectomycorrhizal macrofungi, including boletes, which uncovered a novel genus in the family Boletaceae subfamily Boletoideae.



Boletus roseoflavus, a new species of Boletus in section Appendiculati from China

Phylogenetic analyses based on ribosomal DNA internal transcribed spacer regions and nuclear large subunit ribosome RNA indicate that B. roseoflavus belongs to Boletus section Appendiculati.

Retiboletus, a new genus for a species-complex in the Boletaceae producing retipolides

The phylogenetic analysis using maximum likelihood suggests that both species are differently distributed, and the results are supported by a previous study of Hellwig (1999), separating three groups in the B. retipes/ornatipes -complex based on chemotaxonomical characters.

Revision of Boletus section Appendiculati (Boletaceae) in Bulgaria with a key to the Balkan species

The paper presents the results from the taxonomic revision of Boletus section Appendiculati in Bulgaria, and a dichotomous key for the determination of members is also included.
