Scleroramularia is a genus that includes species of the sooty blotch and flyspeck (SBFS) fungal complex that blemishes the surface of apple, pawpaw, and other fruit. In a survey of SBFS on banana (Musa basjoo), an isolate associated with the flyspeck mycelial type of SBFS was obtained from Zhanjiang, Guangdong, China. Based on analysis of morphology and phylogeny (the nuclear ribosomal internal transcribed space region and translation elongation factor 1-alpha), it was delimited as a new species of Scleroramularia, described here as S. musae. Conidia of S. musae have more septa than other species presently known in the genus.

A new species, Amanita griseofusca in section Vaginatae is described and illustrated here from Pakistan. Distinguishing characters of the new species include medium-sized basidiomata, greyish brown pileus surface with white to beige, membranous volval remnants present as one (large) to a few (small) warts, close lamellae which are cream colored with a pink tone, striations one third of the total pileus radius, broadly ellipsoidal to ellipsoidal basidiospores and white loose saccate volva turning beige at maturity. Molecular data inferred from partial nuc rDNA internal transcribed spacer region (ITS), partial nuc rDNA larger subunit region (LSU) and partial translation elongation factor 1-alpha (tef1) confirms the novelty of the present taxon.

Heimioporus sinensis, collected from tropical and subtropical areas of China, is introduced as a new species based on both morphological characters and molecular data. The species is characterized by the purplish red to deep magenta pileus, the reticulated stipe, the irregularly reticulate to reticulate-alveolate basidiospores 11.5–13.5 × 8–9.5 μm, and a trichodermal to intricately trichodermal pileipellis. Phylogenetic analyses based on the nuc 28S rDNA D1-D2 domains (28S) and the translation elongation factor 1-α gene (tef1-α) showed that H. sinensis is a distinct member of the genus Heimioporus in the subfamily Xerocomoideae.

In this paper we describe a new species of cave fungus belonging to Sporocadaceae (Amphisphaeriales), collected from Gem Cave, Fumin County, Yunnan Province, China. Initial morphological observations confirmed that our fungal collection is a pestalotioid species. Phylogenetic analyses of combined internal transcribed spacer (ITS), β-tubulin (TUB) and translation elongation factor 1-alpha (TEF1α) gene sequence dataset confirmed that our fungus forms an independent branch within Neopestalotiopsis. Thus, we describe our fungus as a new species of Neopestalotiopsis based on both morphology and multigene phylogeny. This is the first-ever report of Neopestalotiopsis from a cave habitat. A full description, micrographs and a phylogenetic tree showing the placement of the new species are provided.

A new species, Cantharellus albus, was collected from southwestern China and described with both morphological and molecular characters. It differs from other species of Cantharellus by its smooth white pileus, white hymenophore, and white stipe, the latter turning yellow after bruising. The phylogenetic tree inferred from the combined dataset of three DNA fragments, namely large subunit ribosomal RNA gene (LSU), RNA polymerase II second largest subunit (rpb2), and translation elongation factor 1-alpha gene (tef1), indicated that the new species is distinct from other species of Cantharellus and is a member of sect. Flavobrunnei within the subgenus Parvocantharellus.

A new Botryosphaeria species (B. sinensia) is described and illustrated from China. It is characterized by erumpent, botryose clustered ascostromata, ostiolate ascomata, bitunicate, 8-spored and clavate asci, filiform, rarely branched pseudoparaphyses, hyaline, 1-celled, fusiform ascospores, and a Fusicoccum asexual morph. The hyaline old and discharged conidia with 1–2 septa, broader spermatia formed in the culture and smaller ascostroma readily distinguished it from B. dothidea and other species in Botryosphaeria. The intergenic spacer (ITS)  and translation elongation factor 1-alpha (EF1) DNA sequence analysis results also support its separation from other Botryosphaeria species. Its relationships with other species of Botryosphaeria are also discussed based on morphology and DNA sequence comparisons.

Abstract The genus Neoconidiobolus was recently established to accommodate all members of the Conidiobolus subgenus Conidiobolus. Based on mitochondrial small subunit (mtSSU), nuclear large subunit (nucLSU) of rDNA and translation elongation factor 1-alpha (TEF1), this study further resolved the genus Neoconidiobolus into three clades, with three new taxa being added. They are N. kunyushanensis B. Huang & Y. Nie, sp. nov., N. lamprauges (Drechsler) B. Huang & Y. Nie, comb. nov., and N. nanodes (Drechsler) B. Huang & Y. Nie, comb. nov. Meanwhile, a morphologial comparison among species in the three clades and a key to the species of the genus Neoconidiobolus are provided herein.

Diaporthe species include important plant pathogenic fungi with extensive host ranges and geographic distributions. In the present study, two new species of Diaporthe causing diebacks from southern China are described and illustrated. Isolates were characterized morphologically and assigned to species based on multigene sequence analyses. Phylogenetic analysis based on the internal transcribed spacer (ITS) region, calmodulin (CAL), histone H3 (HIS), translation elongation factor 1-alpha (TEF1-α) and beta-tubulin (TUB) region grouped isolates into two distinct lineages. Within each linage these species appear to be unique and are described as D. sennae sp. nov and D. sennicola sp. nov, and their relationships with other species in the genus are indicated.

During a biodiversity survey of Alternaria associated with leaf spot and blight of Solanaceae, a large collection of strains was obtained from samples collected in north-western regions of Algeria in 2013–2018 growing seasons. Amongst these strains, three isolates recovered from tomato and potato had morphological traits different from that usually observed for Alternaria species previously reported on Solanaceae. Based on analysis of a sequence dataset corresponding to portions of the glyceraldehyde-3-phosphate dehydrogenase (gpd), translation elongation factor 1-alpha (tef1) and RNA polymerase second largest subunit (rpb2) genes along with morphological observations, isolates were identified as a new species in the section Japonicae. This novel species, described here as Alternaria telliensis, is phylogenetically and morphologically distinct from A. japonica and A. nepalensis in this section. Pathogenicity tests were performed and isolates were found to be weakly pathogenic to tomato and potato (Solanaceae) while highly aggressive on radish, cabbage and turnip (Brassicaceae) plants.

Four new species of Aleurodiscus sensu lato with echinulate basidiospores are described from East Asia: A.alpinus, A.pinicola, A.senticosus, and A.sichuanensis. Aleurodiscusalpinus is from northwest Yunnan of China where it occurs on Rhododendron in montane habitats. Aleurodiscuspinicola occurs on Pinus in montane settings in Taiwan and northwest Yunnan. Aleurodiscussenticosus is from subtropical Taiwan, where it occurs on angiosperms. Aleurodiscussichuanensis is reported from southwest China on angiosperms in montane environments. Phylogenetic relationships of these four new species were inferred from analyses of a combined dataset consisting of three genetic markers, viz. 28S, nuc rDNA ITS1-5.8S-ITS2 (ITS), and a portion of the translation elongation factor 1-alpha gene, TEF1.

Fungi belonging to the genus Cladosporium are cosmopolitan and occur in various substrates and hosts. Nevertheless, this is the first time that we have described this genus colonizing leaf litter submerged in water. We surveyed Cladosporium spp. associated with submerged leaf litter, from three localities belonging to the Atlantic Forest biome in the State of Minas Gerais, Brazil. A multilocus DNA sequence typing approach employing ITS, Actin, and Translation elongation factor 1-α region/genes associated with morphological and cultural analyses were used to identify these species. The species C. angulosum and C. anthropophilum are reported for the first time in Brazil, and a new species for the genus is described here as C. puris.
