First Time

Hericium cirrhatum, a widespread but locally rare tooth fungus is reported for the first time from Pakistan. This species is characterized by white to cream semicircular basidiomata (usually arranged in tiers) with a granular to slightly spiny sterile upper surface, a fertile under surface with 10–15 mm long pointed spines, and ellipsoid to subglobose basidiospores. Morphological characters and DNA sequence analyses inferred from the nuclear ribosomal internal transcribed spacer region (nrITS) confirm the identity of the taxon.

Three New Species

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.

First Time

Recent studies in grape-growing areas including Australia, California, and Spain have revealed an extensive diversity of Diatrypaceae species on grapevines showing dieback symptoms and cankers. However, in South Africa, little is known regarding the diversity of these species in vineyards. The aim of this study was, therefore, to identify and characterize Diatrypaceae species associated with dieback symptoms of grapevine in South Africa. Isolates were collected from dying spurs of grapevines aged 4 to 8 years old, grapevine wood showing wedge-shaped necrosis when cut in cross section as well as from perithecia on dead grapevine wood. The collected isolates were identified based on morphological characters and phylogenetic analyses of the internal transcribed spacer region (ITS) and β-tubulin gene. Seven Diatrypaceae species were identified on grapevine, namely Cryptovalsa ampelina, C. rabenhorstii, Eutypa consobrina, E. lata, E. cremea sp. nov., Eutypella citricola, and E. microtheca. The dying spurs yielded the highest diversity of species when compared with the wedge-shaped necrosis and/or perithecia. C. ampelina was the dominant species in the dying spurs, followed by E. citricola, whereas E. lata was the dominant species isolated from the wedge-shaped necroses and perithecia. These results confirm E. lata as an important grapevine canker pathogen in South Africa, but the frequent association of C. ampelina with spur dieback suggests that this pathogen plays a more prominent role in dieback than previously assumed. In some cases, more than one species were isolated from a single symptom, which suggests that interactions may be occurring leading to decline of grapevines. C. rabenhorstii, E. consobrina, E. citricola, E. microtheca, and E. cremea are reported for the first time on grapevine in South Africa.

Three dictyostelid isolates were found in Spain and Argentina that are morphologically different from known species. These isolates have some features similar to Dictyostelium sphaerocephalum (Oudem.) Sacc., Marchal & É.J. Marchal, but differ in size and sorocarp branching pattern. We sequenced the nuclear ribosomal internal transcribed spacer region to explore phylogenetic relationships among this group of species, including the three new isolates and their closest relatives. In all phylogenetic analyses performed, sequences of all three isolates group together with sequences from “typical” D. sphaerocephalum samples. This result supports previous observations of the morphological plasticity in dictyostelids, especially D. sphaerocephalum, leading us to broaden the classical concept of this species.

Molecular Phylogenetic Data

A new species, Amanita glarea, is described and illustrated from Pakistan. Molecular phylogenetic data derived from internal transcribed spacer (ITS) and nuclear ribosomal large subunit (LSU) regions along with morphological characters make it distinct from other currently known Amanita species. Amanita glarea is characterized by a grayish brown, slightly umbonate, pileus having universal veil remnants and striate margins, a long ringless stipe with a saccate volva bearing yellowish brown patches on the verrucose surface, inamyloid globose to subglobose basidiospores, and a filamentous pileipellis with some inflated round to elongated cells. Phylogenetic analysis of nuclear ribosomal ITS and LSU nucleotide sequences resolve A. glarea with other taxa in Amanita section Vaginatae.

A New Species

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.
