Baorangia duplicatopora is described as a new species from Hainan Province, a tropical region of China. It is morphologically characterized by large to very large basidiomata with a dull rose red, rose pink to purplish red pileus, compound pores, pileus context near hymenophore and stipe context staining blue when injured, a red stipe, and cheilocystidia wider than those of other Baorangia species. Phylogenetic analyses of DNA sequences from part of the 28S gene, the nuc rDNA internal transcribed spacer (ITS) region, and part of the translation elongation factor 1-α gene (TEF1) also confirmed that B. duplicatopora forms an independent lineage within Baorangia. Detailed descriptions, color photographs of fresh basidiomata, and line drawings of microscopic features of the new species are presented. A key to species of Baorangia in the world is also provided.

Lanmaoa rubriceps (Boletaceae, Boletales) is described as a new species from Hainan Province, a tropical region of China. It is morphologically characterized by a red, crimson to orange-red pileus, a hymenophore with stuffed pores when young, pores staining blue and then changing to red-brown when injured, stipe surface staining blue when injured, and a trichodermal pileipellis with uninflated hyphae. Phylogenetic analyses of DNA sequences from part of the 28S gene, the nuc rDNA internal transcribed spacer (ITS) region, and part of the translation elongation factor 1-α gene (tef1-α) also confirmed that L. rubriceps forms an independent lineage within Lanmaoa. Consequently, a detailed description, color photos of fresh basidiomata and line-drawings of microstructures are presented. It’s worth noting that L. rubriceps falls into the genus Lanmaoa phylogenetically but morphological features of the new species match the concept of the genus Cyanoboletus. The reason for the incongruence of molecular and morphological results is that the two most closely related genera share overlapping morphological features and the most important diagnostic feature of Lanmaoa is not constant. In light of these facts, lumping of Lanmaoa and Cyanoboletus into a single genus seems justified.

Buchwaldoboletus xylophilus and Phlebopus portentosus (Boletales) are two non-ectomycorrhizal boletes, which are widely reported in tropical Asia. However, there is little information available about the taxonomy of these two boletes. Here, B. xylophilus and P. portentosus are redescribed based on morphology and molecular phylogenetic analyses of DNA sequences from nuclear 28S rDNA (28S), nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS), translation elongation factor 1-α gene (TEF1) and the RNA polymerase II second largest subunit gene (RPB2). Detailed descriptions, color photos of fresh basidiomata, and line-drawings of microscopic features of the two taxa are presented.

The collections of Xanthoconium from tropical China are investigated on the basis of morphology and molecular phylogenetic analyses of DNA sequences from the nuc 28S rDNA D1-D2 domains (28S), the translation elongation factor 1-α gene (TEF1) and RNA polymerase II second largest subunit gene (RPB2). Two species are recognized in the region, one is the previously described taxon: X. sinensis, the other is described as new: X. fusciceps. Xanthoconium fusciceps is morphologically characterized by a dark brown pileus with a rugulose or pitted surface, non-staining hymenophore and context, golden yellow basidiospores, cystidia with pale yellowish brown, yellowish brown to golden brown pigments, and uninflated hyphae in the pileipellis. Detailed descriptions, color photos of fresh basidiomata and line-drawings of microstructures of the two taxa are presented.

Species of the genus Retiboletus in China were investigated based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU) and the translation elongation factor 1-α gene (TEF1-α). Nine species were recovered from China, including two new and seven known species. The new species, namely Retiboletus ater and R. sinogriseus, from southwestern and northeastern China respectively, are documented and illustrated in this paper. Retiboletus ater is morphologically characterized by its black to grayish black pileus, white to grayish hymenophore, black to blackish stipe and white to grayish white context. Retiboletus sinogriseus is morphologically characterized by its brown to grayish-brown pileus, yellow to grayish-yellow hymenophore, pale yellow to brownish stipe and yellow to brownish-yellow context. Descriptions and line drawings of these two novel species and their comparisons with allied taxa are presented.

Collections identified as “S. placidus” from the south of China, a subtropical/tropical region, were investigated using morphology and phylogenetic analyses of DNA sequences from nuc rDNA internal transcribed spacer (ITS). The results indicated that these specimens from subtropical/tropical China are not true S. placidus but represent a new species. Suillus huapi sp. nov. is characterized by a yellowish white to grayish yellow pileus when young, brown to dark brown when old, surface of pores and stipe usually beaded with droplets of milky liquid when young, a stipe without obvious granules, a pileipellis as an ixocutis, and an association with two-needled pines including P. caribaea, P. massoniana and P. yunnanensis.

Boletellus and Heimioporus, two genera of Boletaceae with ornamented basidiospores, are shown to be distinct genera on the basis of phylogenetic analyses of nuclear ribosomal large-subunit and translation elongation-factor 1α DNA sequences. Comparison of spore ornamentation type – longitudinally ribbed in Boletellus v. punctate, alveolate-reticulate in Heimioporus – are further evidence for distinction. Analyses of multiple accessions from the Americas, Asia and Australia support the monophyly of Heimioporus and a ‘core Boletellus’ clade, containing the type species, B. ananas (M.A.Curt.) Murrill, and approximately seven additional species. Tests of alternative phylogenetic topologies could not reject monophyly of a more inclusive group containing the core Boletellus clade and six other species. Heimioporus australis Fechner & Halling, H. cooloolae Fechner & Halling, Boletellus deceptivus Halling & Fechner, B. reminiscens Halling & Fechner and B. sinapipes Fechner, K.Syme, R.Rob. & Halling are described as new species. Phylogenetic analyses also support the following new combinations: Aureoboletus projectellus (Murrill) Halling, A. mirabilis (Murrill) Halling, Hemileccinum subglabripes (Peck) Halling and the new name, Xerocomus tenax Nuhn & Halling.

Cylindrocarpon-like asexual morphs infect herbaceous and woody plants, mainly in agricultural scenarios, but also in forestry systems. The aim of the present study was to characterize a collection of Cylindrocarpon-like isolates recovered from the roots of a broad range of forest hosts from nurseries showing decline by morphological and molecular studies. Between 2009 and 2012, 17 forest nurseries in Spain were surveyed and a total of 103 Cylindrocarpon-like isolates were obtained. Isolates were identified based on DNA sequences of the partial gene regions histone H3 (his3). For the new species, the internal transcribed spacer and intervening 5.8S nrRNA gene (ITS) region, β-tubulin (tub2), and translation elongation factor 1-α (tef1) were also used to determine their phylogenetic position. Twelve species belonging to the genera Cylindrodendrum, Dactylonectria, and Ilyonectria were identified from damaged roots of 15 different host genera. The species C. alicantinum, D. macrodidyma, D. novozelandica, D. pauciseptata, D. pinicola, D. torresensis, I. capensis, I. cyclaminicola, I. liriodendri, I. pseudodestructans, I. robusta, and I. rufa were identified. In addition, two Dactylonectria species (D. hispanica sp. nov. and D. valentina sp. nov.), one Ilyonectria species (I. ilicicola sp. nov.), and one Neonectria species (N. quercicola sp. nov.) are newly described. The present study demonstrates the prevalence of this fungal group associated with seedlings of diverse hosts showing decline symptoms in forest nurseries in Spain.
