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. Comments on the ecology and conservation status of both species, and a revised key to the foliicolous Strigula species of New Zealand are provided.

A New Species

During the study of Usnea from China, we identified and illustrated a new species, Usnea sulphuridiscoidea S. Y. Guo & L. F. Han from the Ailaoshan Mountain of Southwest China, based on morphological characteristics and nrDNA ITS sequence data. This new species can be distinguished morphologically from other apotheciate members of Usnea by the special lateral apothecia with sulphur disc, the inflated branches with glossy surface and numerous papillae as well as many fibrils, meanwhile lacking pseudocyphellae and soralia. The nrDNA ITS sequence data supported the recognition of the new species.

Type Studies

AbstractSection Anomali is a species-rich group in North America belonging to Cortinarius, the most diverse genus in the Agaricales. This study is based on extensive morphological investigations and molecular methods using 191 nrDNA ITS sequence data and recovered 43 phylogenetic species from which 14 are described here as new to science. We sequenced ten type materials which belonged to eight species. The synonymy of C. caesiellus with C. albidipes and C. copakensis with C. albocyaneus is proposed here. The North American occurrence of four species (C. albocyaneus, C. anomalus, C. caninus, and C. tabularis), so far known only from Europe, was confirmed. Thirteen species were not formally described here due to lack of relevant information. An identification key to the known Anomali species in North America is provided.

Expanded Concept

Phylogenetic hypotheses are presented for Pultenaea based on cpDNA (trnL–F and ndhF) and nrDNA (ITS) sequence data. Pultenaea, as it is currently circumscribed, comprises six strongly supported lineages whose relationships with each other and 18 closely related genera are weak or conflicting among datasets. The lack of resolution among the six Pultenaea clades and their relatives appears to be the result of a rapid radiation, which is evident in molecular data from both the chloroplast and nuclear genomes. The molecular data provide no support for the monophyly of Pultenaea as it currently stands. Given these results, Pultenaea could split into many smaller genera. We prefer the taxonomically stable alternative of subsuming all 19 genera currently recognised in Pultenaea sensu lato (= the Mirbelia group) into an expanded concept of Pultenaea that would comprise ~470 species.

A New Species

Russula buyckii, a new species of Russula (subgen. Incrustatula, sect. Lilaceinae and subsect. Lilaceinae) is described from Eastern Himalaya, India. Its macro- and micro-morphological features are described in detail and compared with those of similar species. Identification and categorization of R. buyckii was supported by the molecular phylogenetic analysis based on the nrDNA ITS sequence data.

Poaceae Family

Phylogenetic relationships of the whole Poaceae family inferred from the sequence data of rDNA (ITS) support the hypothesis that the arundinoids are monophyletic, not polyphyletic as previously proposed. The ITS sequence phylogeny of 42 arundinoid species demonstrates an early divergence of the Aristideae and three major groupings, corresponding loosely to the tribes Aristideae, Arundineae and Danthonieae. The Arundineae are resolved into two paraphyletic clades. In one clade, Arundo, Monachather, and Dregeochloa are the sister group to Amphipogon and Diplopogon. In the other clade, Phragmites, Molinia, Gynerium, Thysanolaena, Spartochloa, and Cyperochloa are the sister group to Eriachne and Micraira. Arundo is not closely related to Phragmites. The Danthonieae clade, including taxa from Africa, Australia, New Guinea, New Zealand, the South American Cortaderia, and the North American Danthonia, appears to be monophyletic. However, the genus Merxmuellera is polyphyletic.

A New Species

The new species, Tragopogon anatolicus A.Duran, B.Doğan & Coşkunç. sp. nov. (Asteraceae) is described and illustrated from Cilo Mt. (Hakkari), south-east Anatolia, Turkey. Tragopogon anatolicus is a local endemic, most similar to T. buphthalmoides (DC.) Boiss. Diagnostic morphological characters of these two closely related taxa are discussed. A phylogenetic analysis based on nrDNA ITS sequence data indicated that T. buphthalmoides is the sister species of the new taxon. Ecology, biogeography and conservation status of the new species are also presented.
