Soil is one of the main reservoirs of fungi. The aim of this study was to study the richness of ascomycetes in a set of soil samples from Mexico and Spain. Fungi were isolated after 2% w/v phenol treatment of samples. In that way, several strains of the genus Penicillium were recovered. A phylogenetic analysis based on internal transcribed spacer (ITS), beta-tubulin (BenA), calmodulin (CaM), and RNA polymerase II subunit 2 gene (rpb2) sequences showed that four of these strains had not been described before. Penicillium melanosporum produces monoverticillate conidiophores and brownish conidia covered by an ornate brown sheath. Penicillium michoacanense and Penicillium siccitolerans produce sclerotia, and their asexual morph is similar to species in the section Aspergilloides (despite all of them pertaining to section Lanata-Divaricata). P. michoacanense differs from P. siccitolerans in having thick-walled peridial cells (thin-walled in P. siccitolerans). Penicillium sexuale differs from Penicillium cryptum in the section Crypta because it does not produce an asexual morph. Its ascostromata have a peridium composed of thick-walled polygonal cells, and its ascospores are broadly lenticular with two equatorial ridges widely separated by a furrow. All four new species are xerophilic. Despite the genus Penicillium containing more than 480 known species, they are rarely reported as xerophilic.

Acrophialophora liboensis, a new fungus from soil samples in Libo County, Guizhou Province, China, is illustrated and described on the basis of morphological and molecular sequences data. Phylogenetic analysis based on internal transcribed spacer (ITS) and β-tubulin sequences demonstrated that A. liboensis is a distinct species closely related to A. cinerea and A. furcata. Morphologically, A. liboensis is characterized by solitary and lateral phialides tapering into thin necks and long chains of ellipsoidal or oval conidia. The ex-type living culture has been deposited in CGMCC, Beijing City, China.

Inocybe griseorubida sp. nov. is described from Kerala State, India. A comprehensive description, photographs, and comparisons with phenetically similar species are provided. The nuclear ribosomal internal transcribed spacer region (ITS), a portion of the nuclear ribosomal large subunit (nLSU) and a portion of the nuclear second-largest subunit of RNA polymerase II (rpb2) gene of this species were sequenced and analyzed. Phylogenetic analysis of rpb2 sequences confirmed both the novelty of the species and its placement within the Pseudosperma clade.

A survey of Penicillium in the fynbos biome from South Africa resulted in the isolation of 61 species of which 29 were found to be new. In this study we focus on Penicillium section Canescentia, providing a phylogenetic re-evaluation based on the analysis of partial beta-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2) sequence data. Based on phylogenies we show that five fynbos species are new and several previously assigned synonyms of P. canescens and P. janczewskii should be considered as distinct species. As such, we provide descriptions for the five new species and introduce the new name P. elizabethiae for the illegitimate P. echinatum. We also update the accepted species list and synonymies of section Canescentia species and provide a review of extrolites produced by these species.

Three species of Entoloma with white basidioma in subgenus Alboleptonia from China are reported in this paper. Entoloma crocotillum is described as new to science from high altitudes in southwestern China. It is characterized by the small, white to pinkish pileus covered with matted-appressed fibrils, relatively large basidiospores with 5–6 angles, and the common presence of clamp-connections. Entoloma sulcatum, a new Chinese record, and E. stylophorum are documented based on new collections. Additionally, ITS (internal transcribed spacer region), nLSU (nuclear large subunit), and RPB2 (RNA polymerase II second largest subunit) sequences of E. crocotillum were successfully generated, and the phylogenetic positions of the three species among Alboleptonia species and other entolomatoid groups are preliminarily analyzed based on the combined nLSU and RPB2 dataset. The phylogenetic analysis showed that E. crocotillum is most closely related to E. sericellum and that Alboleptonia is not a monophyletic group.

Inocybe distincta sp. nov. is described from Kerala State, India. A comprehensive description, photographs, line drawings and comments are provided. The nuclear ribosomal internal transcribed spacer region (ITS), a portion of the nuclear ribosomal large subunit (nrLSU) and a portion of the nuclear second-largest subunit of RNA polymerase II (RPB2) gene of this species were sequenced and analyzed. BLASTn searches using nrLSU and RPB2 sequences and subsequent ML phylogenetic analysis of combined nrLSU and RPB2 sequences confirmed that Inocybe distincta is a representative of the Nothocybe lineage. As the Nothocybe lineage is assumed to have affinities to I. cutifracta, and as there are different interpretations of that species, we examined the holotype of I. cutifracta collected by T. Petch and another collection from Sri Lanka identified as I. cutifracta by D. N. Pegler, and we present here our observations on these collections.

During survey on rock-inhabiting fungi from karst habitats in Guizhou, China, two new species in Cyphellophora were discovered and identified. Phylogenetic analysis based on combined sequences of the nuclear large subunit (nucLSU) and internal transcribed spacer (ITS) region of ribosomal DNA revealed that the tested isolates, clustered into two clades that well affiliated in the genus of Cyphellophora. Morphological characteristics were also supported the estabolishment of the new species. Herewith Cyphellophora botryose sp. nov. and Cyphellophora guizhouensis sp. nov. were described and their differences from closely related species were discussed.

A new polypore, Ceriporia albomellea, collected from tropical China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported C. albomellea as a distinctive species belonging to Ceriporia.

Roussoella guttulata sp. nov. (Roussoellaceae) was found on bamboo culms collected in the northeast of Thailand. Roussoella guttulata differs from other species in having immersed, gregarious, black pseudoascostromata, single and central ostiole with periphyses, thin-walled peridium composed of cells of textura angularis to textura prismatica and yellowish brown ascospores. The multigene phylogenetic analysis shows that the new species forms a distinct lineage basal to R. hysterioides, R. japanensis, R. scabrispora and R. verrucispora. The new species is compared with closely related Roussoella species. A full description, color photo plates and a phylogenetic tree to show the placement of the new species are provided.

Three new species of Russula collected from southern China are proposed based on morphological characters and phylogenetic analysis of internal transcribed spacer (ITS) sequences. Russula bubalina sp. nov. is characterized by cinnamon buff to pink pileus with striate margin, interveined and forked lamellae, basidiospores with warty ornamentations not forming reticulum, hymenial cystidia becoming brown in sulphovanillin (SV) and slender terminal cells in suprapellis. R. pseudobubalina sp. nov. is closely related to Russula bubalina in macro-morphology, but it can be recognized by its unforked lamellae, shorter cheilocystidia, bigger basidia and basidiospores with lower ornamentations. Russula subatropurpurea sp. nov. can be recognized by the purplish brown pileus, mild-tasted and white context changing to light purplish red with FeSO4, white and forking lamellae without lamellulae, long hymenial cystidia becoming brown in SV. Both morphological and phylogenetic analysis consistently confirmed the distinct positions of three new species in subg. Heterophyllidia subsection Heterophyllinae.
