Arundinella stenostachya, a new species, is described and illustrated. It is morphologically similar to A. decempedalis and A. bengalensis, but differs from the former species by the length of panicle branches, type of trichome on nodes and pedicels length, and from the latter in height and diameter of culms, the length and width of leaf blades, pedicels length, and the length of panicles and branches.

In this study, a new species, P. nana, from northeast Chongqing in the north of the Yangtze River is described and illustrated. Bayesian inference and maximum likelihood analyses based on two nuclear ribosomal DNA regions (ITS and ETS) and three plastid DNA markers (rpl32-trnL, rps16, and trnL-trnF) were carried out to explore the phylogenetic position of the new species within Paraphlomis.

With the aim of clarifying the number of Tulostoma species in Macedonia, and to verify some previous collections, molecular analyses were carried out on four morphologically identified species collected in different habitats (at the edges of oak or juniper forests, pine plantations, meadows, rocky places, roadsides). Sixty-two new sequences were generated and compared with recently published sequences included in public databases. According to the barcoding sequences fourteen Tulostoma species are identified in Macedonia and ten of them were assigned to known species: Tulostoma brumale, T.

Two new species found in Northwestern Pakistan in the mushroom genus Amanita are described and illustrated. Phylogenetic data derived from nuclear ribosomal ITS and LSU regions along with morphological characterizations indicate that these species are novel. Amanita cinis is a member of section Roanokenses, while A. olivovaginata is representative of the section Vaginatae. Amanita emodotrygon, recently described from the state of Uttarakhand, India, is new to Pakistan.

A new species in the genus Russula from the mixed coniferous forest of District Shangla, Khyber Pakhtunkhwa, Pakistan is described and illustrated. Phylogenetic data derived from DNA sequences of nuclear ribosomal internal transcribed spacer (ITS), along with morphological characterizations, indicate the species is novel. Russula shanglaensis sp. nov. is distinct from other known species in subsect. Virescentinae.

A new species of Pseudocercospora is described causing leaf spot disease on Crotalaria assamica from India. The identity of isolate was based on asexual morphs, cultural characteristics and phylogenetic analyses of partial nuclear ribosomal 28S large subunit and complete internal transcribed spacer rDNA sequence data with high statistical support value. Morphologically this species has characters similar to allied species in genus Pseudocercospora but differs in having catenate and branched conidia.

The genus Sechium includes 11 species, which are highly related to the genus Sicyos. Sechium is native to Mesoamerica, but only S. edule and S. tacaco have been domesticated. Sechium edule is the most exploited species of the genus due to its broad phenotypic variability. A total of 68 samples from the species S. chinantlense, S. compositum, S. hintonii and S. edule were evaluated, as well as their respective varietal complexes (albus, nigrum and virens groups), thereby amplifying the loci of mitochondrial DNA (CoxIII), chloroplast DNA (rbcL) and the nuclear ribosomal ITS1-5.8S-ITS2 region.

Huyen-sam (Vietnamese name) which belongs to Scrophularia L. genus is a valuable herb. This medicinal plant is classified as Scrophularia ningpoensis Hemsl. Huyen-sam roots, which contain a large amount of bioactive compounds, have a similar morphology to its relatives. DNA barcodes promise to be a precise and reliable tool for distinguishing the processed Huyen-sam materials from their counterfeits. However, studies about using DNA barcodes for classification of Scrophularia L. in Vietnam are not available. Here, we conducted a taxonomic analysis of eight Scrophularia L.

Five species of Comesomatidae: Dorylaimopsis halongensis, Hopperia dolichurus, Paracomesoma lissum, Sabatieria doancanhi and Sabatieria praedatrix were identified based on morphological characters of males. To expose the systematic position of these comesomatids, we obtained nucleotide sequences of nuclear ribosomal DNA (D2/D3 and ITS region). The results showed the clear molecular differences between species in the Comesomatidae that proved to the morphology data.

Primula × uzungolensis Terzioğlu & Coşkunçelebi, a natural hybrid from north-eastern Anatolia, is described and illustrated with its parents. Based on its morphology and molecular characteristics, we conclude that P. × uzungolensis is a new natural hybrid between P. acaulis (L.) Hill subsp. rubra (Sm.) Greuter & Burdet and P. veris L. subsp. columnae (Ten.) Maire & Petitmengin.
