<em>Cyanoboletus macroporus</em> belonging to <em>C. pulverulentus</em> species complex is designated as a new species from the moist temperate and sub-alpine oak forests of Pakistan after in depth macroscopic, microscopic and phylogenetic analyses using the ITS region of nrDNA as well as comparison with allied taxa. This species belonging to Boletoid group is morphologically distinguished from allied taxa (<em>Cyanoboletus flavosanguineus</em>, <em>C. hymenoglutinosus</em>, <em>C. pulverulentus</em>, <em>C. rainisii</em>, and <em>C. sinopulverulentus</em>) by wider openings of pores. <em>C. macroporus</em> is also phylogenetically distinct from <em>C. sinopulverulentus</em> and <em>C. pulverulentus</em>, the most closely related species. Phylogenetic analysis outlined the existence of previously unknown species of this genus. Field photographs of fresh basidocarps and line drawings of micro-characters are provided along with a phylogenetic tree as well as a comparison table and a key of distinctive features of all the species in this genus. This is the first authentic species belonging to <em>Cyanoboletus</em> from Pakistan. Previously, only <em>C. pulverulentus</em> has been mentioned in literature, but no morphological data is available regarding this report. With the addition of this taxon, species number of <em>Cyanoboletus</em> will increase to eight. From Pakistan, despite of the fact that there is great diversity of mushrooms in moist temperate areas (Yousaf et al. 2012), this is the first study that describes a species belonging to <em>Cyanoboletus</em> genus. Previously only one ambiguous species, <em>Cyanoboletus pulverulentus</em>, has been mentioned in literature (Iqbal & Khalid 1996), but with no available materials that could confirm this finding. In this study, <em>Cyanoboletus macroporus</em> is described as a new to science and increase the current species number of <em>Cyanoboletus</em> to eight.

Xylodon (Hymenochaetales, Basidiomycota) is the largest segregate genus of Hyphodontia s.l. Based on molecular and morphological data, 77 species are accepted in Xylodon to date. Phylogenetic analyses of ITS and 28S sequences, including 38 new ITS and 20 28S sequences of Xylodon species, revealed four species new to science. The new taxa X.exilis, X.filicinus, X.follis and X.pseudolanatus from Taiwan, Nepal, Réunion, Belize, and USA are described and illustrated. In addition, species concepts for Odontiavesiculosa from New Zealand and Xylodonlanatus from U.S.A. are revised and the new name X.vesiculosus is proposed. Phylogenetic analyses of the ITS region placed X.spathulatus, X.bubalinus and X.chinensis in a strongly supported clade and demonstrated that they are conspecific. Palifer and Odontiopsis are synonymised under Xylodon based on morphological and sequence data. The following new combinations are proposed: X.erikssonii, X.gamundiae, X.hjortstamii, X.hyphodontinus, X.septocystidiatus and X.verecundus. Line drawings of X.cystidiatus, X.hyphodontinus, X.lanatus and X.vesiculosus, as well as photographs of X.raduloides basidiomata, are provided. A key to X.lanatus and similar species is presented.

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.

Fungal communities associated with macroalgae remain largely unexplored. To characterize algicolous fungal communities using culture dependent methods, macroalgae were collected from different sampling sites in the Ria de Aveiro estuary, Portugal. From a collection of 486 isolates that were obtained, 213 representative isolates were selected through microsatellite-primed PCR (MSP-PCR) fingerprinting analysis. The collection yielded 33 different genera, which were identified using the ITS region of the rDNA. The results revealed that the most abundant taxa in all collections were Acremonium-like species: Alternaria, Cladosporium, Leptobacillium and Penicillium. The fungal community composition varied with macroalgae species. Through multilocus phylogenetic analyses based on ITS, tub2, tef1-α and actA sequences, in addition to detailed morphological data, we propose Cladosporium rubrum sp. nov. (type strain=CMG 28=MUM 19.39) and Hypoxylon aveirense sp. nov. (type strain=CMG 29=MUM 19.40) as novel species.

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.

ABSTRACTAmong many convergently evolved sequestrate fungal genera in Boletaceae (Boletales, Basidiomycota), the genus Octaviania is the most diverse. We recently collected many specimens of Octaviania subg. Octaviania, including several undescribed taxa, from Japan and the Americas. Here we describe two new species in subgenus Octaviania, O. tenuipes and O. tomentosa, from temperate to subtropical evergreen Fagaceae forests in Japan based on morphological observation and robust multilocus phylogenetic analyses (nrDNA ITS and partial large subunit [LSU], translation elongation factor 1-α gene [TEF1] and the largest subunit of RNA polymerase II gene [RPB1]). Based on specimens from the Americas as well as studies of the holotype, we also taxonomically re-evaluate O. asterosperma var. potteri. Our analysis suggests that O. asterosperma var. potteri is a distinct taxon within the subgenus Octaviania so we recognize this as O. potteri stat. nov. We unexpectedly collected O. potteri specimens from geographically widespread sites in the USA, Japan and Colombia. This is the first verified report of Octaviania from the South American continent. Our molecular analyses also revealed that the RPB1 sequence of one O. tenuipes specimen was identical to that of a closely related species, O. japonimontana, and that one O. potteri specimen from Minnesota had an RPB1 sequence of an unknown species of O. subg. Octaviania. Additionally, one O. japonimontana specimen had an unusually divergent TEF1 sequence. Gene-tree comparison and phylogenetic network analysis of the multilocus dataset suggest that these heterogenous sequences are most likely the result of previous inter- and intra-specific hybridization. We hypothesize that frequent hybridization events in Octaviania may have promoted the high genetic and species diversity found within the genus.

AbstractThe eastern Mediterranean basin hosts a remarkably high plant diversity. Historical connections between currently isolated areas across the Aegean region and long-distance dispersal events have been invoked to explain current distribution patterns of species. According to most recent treatments, at least two Cymbalaria species occur in this area, Cymbalaria microcalyx and C. longipes. The former comprises several intraspecific taxa, treated at different ranks by different authors based on morphological data, evidencing the need of a taxonomic revision. Additionally, some populations of C. microcalyx show exclusive morphological characters that do not match any described taxon. Here, we aim to shed light on the systematics of eastern Mediterranean Cymbalaria and to propose a classification informed by various sources of evidence. We performed molecular phylogenetic analyses using ITS, 3’ETS, ndhF and rpl32-trnL sequences and estimated the ploidy level of some taxa performing relative genome size measures. Molecular data combined with morphology support the division of traditionally delimited C. microcalyx into C. acutiloba, C. microcalyx and C. minor, corresponding to well-delimited nrDNA lineages. Furthermore, we propose to combine C. microcalyx subsp. paradoxa at the species level. A group of specimens previously thought to belong to Cymbalaria microcalyx constitute a well-defined phylogenetic and morphological entity and are described here as a new species, Cymbalaria spetae. Cymbalaria longipes is non-monophyletic, but characterized by being glabrous and diploid, unlike other eastern species. The nrDNA data suggest at least two dispersals from the mainland to the Aegean Islands, potentially facilitated by marine regressions.
