A New Species

A new species, Melanoleuca juliannae is described from Hungary. Its most outstanding character is the presence of a violaceous-blue colour in the stipe base. Sequence comparisons with other Melanoleuca species revealed highly similar but decolourate members of the species, lacking the remarkable colour of the stipe. These specimens are described as Melanoleuca juliannae var. decolorans based on three collections from the Czech Republic and Italy. Detailed macro- and microscopic descriptions of the new species are given. The position of M. juliannae within subgen. Urticocystis was confirmed by DNA sequence data of the ITS region of the nuclear ribosomal RNA gene cluster and translation elongation factor 1-alpha (tef1). Although intra-individual heterogeneity in ITS region was revealed in some specimens of the type variety, the tef1 sequences lack a similar heterogeneity.

Thirty-four Lycoperdon specimens from Korea were examined with the internal transcribed spacer (ITS) region of ribosomal DNA sequence data. The result of the ITS sequences phylogenetic analysis indicated that the Korean specimens represented nine different species. To confirm the taxonomic position of these species, we conducted an intensive morphological investigation, and additional phylogenetic investigation of the protein coding regions RNA polymerase subunit II (RPB2) and translation elongation factor 1-alpha (TEF1). We discovered two new species (L. albiperidium and L. subperlatum) and one (L. ericaeum) newly discovered in Korea. Lycoperdon albiperidium is closely related to L. ericaeum based on ITS, RPB2 and TEF1 sequence data, but these species were distinguishable by morphological characteristics, especially the shape of the basidiocarps, the diameter of the eucapillitial threads and the size of the basidospores. Lycoperdon subperlatum is quite similar to the European and American L. perlatum based on morphological characteristics. However, L. subperlatum is clearly distinct from European and American L. perlatum based on ITS, RPB2 and TEF1 sequence data, and somewhat differs from them in macro- and microscopic characteristics. Based on morphological characteristics, L. ericaeum is related to L. subumbrinum and L. lividum but it is distinguishable by the presence of fragile, eucapillitial threads, the diameters of the threads and ITS sequences. Here, we describe four Lycoperdon species collected in Korea.

A New Species

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.

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.

A New Species

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.

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

Pilea nonggangensis Y. G. Wei, L. F. Fu & A. K. Monro, a new species from Guangxi, China is described and illustrated. The new species is morphologically most similar to P. basicordata from which it differs by being dioecious, having peltate leaf blades, membranous stipules, paired inflorescences and larger bracts. Nuclear ribosomal internal transcribed spacer (ITS) region and plastid trnL-F intron spacer (trnL-F) DNA sequence data from the new species and 20 local congeneric species are used to resolve the systematic position of the new species within Pilea. Despite vastly different morphology the molecular evidence suggests that P. nonggangensis is most closely related to P. pseudonotata. A Global Species Conservation Assessment classifies P. nonggangensis as Vulnerable (VU).

Fungal Colony

During June 2018, several symptomatic fig (Ficus carica) cuttings, showing twig blight, subcortical discolouration and apical dieback were collected from a nursery in Catania province, Sicily (Italy). Isolations from diseased tissue consistently showed the presence of the same fungal colony. Morphology of the fungal isolates together with sequence data of the nuclear rDNA internal transcriber spacer (ITS) region, translation elongation factor 1-alpha (tef1) gene and partial beta-tubulin (tub2) gene of representatives isolates revealed the presence of the fungus Neofusicoccum parvum. Pathogenicity tests were conducted by inoculating fig cuttings with mycelial plugs. After 10 days, the inoculated plants developed cankers similar to those observed in the greenhouse and after 26 days all inoculated plants were dead. To the best of our knowledge, this is the first report worldwide of N. parvum causing disease on this host.

A New Species

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.

The grass Ammophila breviligulata (American beachgrass) is known to host an endophyte of the genus Epichloë. Based on morphological characteristics it was originally identified as Acremonium typhinum var. ammophilae and is currently designated as Epichloë typhina var. ammophilae. However, the Epichloë species has not previously been identified based on DNA sequence data. Based on phylogenetic placement of beta-tubulin and translation elongation factor 1-alpha DNA sequences the endophyte is identified as a member of E. amarillans rather than E. typhina.
