Paris variabilis, a new species from the Wumengshan Mountains, southwestern China, is described and illustrated. The new species is placed in Paris section Euthyra. The new taxon was determined to be most morphologically similar to P. vietnamensis but differs in its oblong leaf blades with an acute apex, stamens 2–4 × petal number, greenish yellow filaments and an enlarged, purplish red style base. The phylogenetic placement of this species was assessed based on nuclear ribosomal ITS DNA sequences data. The results of morphological and phylogenetic analyses support the status of the taxon as a new species.

A new species, Strigula oleistrata, segregated from S. novae-zelandiae is described. The new species is widely sympatric with Strigula novae-zelandiae from which it is separated by a range of morphological characters and also by its nrDNA ITS sequence. As a result of this segregation, a new circumscription of S. novae-zelandiae is also provided.

A New Species

Agaricus is a monophyletic genus with a worldwide distribution and more than 400 described species. The genus grows on soil and can be easily recognized by the presence of an annulus on the stipe and free lamellae which become dark brown with spore maturation. Although Agaricus is easily recognized in the field because of its macroscopic characters, identification at the species level is difficult. Based on specimens collected in the states of Paraná and Santa Catarina, in the south of Brazil, we propose a new species Agaricus globocystidiatus. The new taxon is distinguished mainly by the presence of pleurocystidia, a rare morphological character in Agaricus. Molecular analyses based on nuc rITS1-5.8-ITS2 (ITS) barcode sequences show that A. globocystidiatus belongs to Agaricus subg. Minoriopsis.

Aim. To obtain new data on the species diversity, phylogenetic structure, and ecological characteristics of thelephoroid fungi (Thelephorales, Basidiomycota) in the Republic of Dagestan.Material and Methods. Both micromorphological and molecular analyses were used for studying of the fungal specimens collected by the authors in 2018-2019 in the Gunibsky and Magaramkentsky Districts of Dagestan. Additional specimens from the Mycological Herbarium of the Komarov Botanical Institute of the Russian Academy of Sciences (LE) were studied. The ITS region of nrDNA was amplified with two pairs of primers, ITS1F/ITS4 and ITS5/ITS4.Results. Sixteen ITS sequences belonging to eight species were obtained from the studied material. Of them, 14 sequences clustered in the Tomentella clade and two sequences nested within the Odontia clade. Four species – Odontia duemmeri, Tomentella lapida, T. radiosa, T. terrestris – were registered for the first time for Dagestan. Detailed information on the specimens studied is presented. Species identification of Odontia fibrosa, Tomentella badia, T. ferruginea, and T. stuposa was confirmed by ITS nrDNA analysis.Conclusion. Data on the species richness of the genera Odontia and Tomentella in Dagestan is updated, and the species T. lilacinogrisea is excluded from the regional funga. To date the genera Odontia and Tomentella in the Republic of Dagestan are represented by three and fifteen species, respectively.

We rediscovered two species of toads, Bufo stomaticus peninsularis and Bufo brevirostris, which were described from Peninsular India 84 and 101 years ago, respectively, but have not been reported since. Because the name-bearing types of both species are either damaged or lost, we provide detailed redescriptions, morphological comparisons, and insights into phylogenetic relationships with closely related members of the genus Duttaphrynus sensu lato, based on new material from the type locality of each species. We clarify and validate the identity of D. brevirostris, which was rediscovered from multiple localities in the Malenadu and adjoining coastal regions of Karnataka. We also demonstrate that Bufo stomaticus peninsularis, which was considered a synonym of Duttaphrynus scaber, is a distinct species. Bufo stomaticus peninsularis differs from Duttaphrynus scaber morphologically and genetically, and is more closely related to members of the Duttaphrynus stomaticus group. We also clarify the identity of the namesake species of the Duttaphrynus stomaticus group, which is reported widely in India and neighbouring countries, but lacks sufficient taxonomic information due to its brief original description and reportedly untraceable type material. We located and studied the complete syntype series of D. stomaticus, probably for the first time in over a century, and we report on the status of available specimens, provide detailed description of a potential type, compare it to related species, and clarify the species’ geographical range. Our molecular analyses suggest that D. stomaticus is minimally divergent from, and possibly conspecific with, D. olivaceus. Our analyses also clarify its relationship to the closely-related D. peninsulariscomb. nov., with which it was previously confused. Finally, our study provides other insights into the phylogenetic relationships and genetic differentiation among various species of Duttaphrynus toads.

Abstract Two new species of ryocalanoid copepods (Crustacea: Calanoida), Ryocalanus squamatus sp. nov. and Yrocalanus kurilensis sp. nov. are described together with a female of Ryocalanus infelix Tanaka, 1956, type species for the genus Ryocalanus Tanaka, 1956, from abyssal depths in the Kurile-Kamchatka trench. The new species can be assigned to the superfamily Ryocalanoidea based on the segmentation and armature of the swimming legs and the modification of the male right antennule. A new interpretation of the fusions of segments in the male right antennule of Ryocalanus shows the marked differences between the ryocalanoidean genera. The status of Ryocalanoidea within the Calanoida is discussed based on morphology and a first molecular multi-gene analysis with cytochrome oxidase subunit I, cytochrome b, nuclear ribosomal 18S and 28S rDNA and internal transcribed spacer 2. This analysis supports the close interrelationship between Ryocalanoidea and Spinocalanoidea. The monophyletic status of Ryocalanoidea could not be retrieved in the phylogenetic analysis, as specimens of Yrocalanus formed a clade within Spinocalanoidea. The inconclusive results between morphological and molecular analyses are discussed with a proposition to keep the current system until more males of taxa belonging to the Spinocalanoidea are discovered, as the male antennule plays a crucial role in the interpretation of relationships between Ryocalanoidea and Spinocalanoidea.

New Variety

Phytolacca americana var. huadongensis is described and illustrated as a new taxon from eastern China. This new variety differs from P. americana var. americana and var. rigida by the pendulous or arciform thyrsoid inflorescences and infructescences. This new taxon is also morphologically similar to P. sanguinea and P. thyrsiflora, from which can be distinguished by both the pendulous inflorescence (P. sanguinea and P. thyrsiflora have erect thyrsoid inflorescences), and the 10(11)-carpellate gynoecia (vs. 9-carpellate gynoecia in P. sanguinea and 6–9-carpellate gynoecia in P. thyrsiflora).
