The new taxon, Begonia xenos C.W.Lin, Phonep. & Rahm is similar to B. sinofloribunda Dorr in habit and leaf shape, but the new species differs in its staminate flowers having 4 tepals (vs. 2) with slightly crenulate (vs. entire) margins, pistillate flowers with 5 tepals (vs. 2 or 3) and a 2-locular (vs. 3-locular) ovary.
查看更多>>摘要：Commiphora omundomba, described here as a new species, is known only from the Kaokoveld Centre of Endemism, a biogeographical region in southwestern Angola and Northwestern Namibia. It has hitherto been confused with C. dinteri from west-central Namibia, but both morphological and molecular evidence support a distinction between the two species. Phylogenetic analysis of DNA sequence data indicates that C. omundomba shares most-recent common ancestry with C. buruxa, a species limited to the Gariep Centre of Endemism in southwestern Namibia. Diagnostic morphological characters for C. omundomba include the white, viscous exudate, smooth bark and glabrous, trifoliolate leaves. Photographs of the plant and a distribution map are provided. The new species is mainly confined to near the Atlantic coast of the northern Namib Desert, and is widespread and locally common between Santa Maria in Angola and Puros in Namibia.
查看更多>>摘要：Euploca riochiquensis is described and illustrated as a species new to science endemic to the Rio Chico valley in Chuquisaca, Bolivia. Morphologically it resembles E. lagoense in its solitary axillary flowers but differs conspicuously in its shrubby habit. Its phylogenetic position, conservation status and distribution are discussed.

Phylogenetic analyses based on ITS, LSU, tef1-alpha and tub2 DNA sequence data revealed this new species with a distinct asexual morph belongs to the family Pseudoplagiostomataceae. Pseudoplagiostoma dipterocarpicola is closely related to P. mangiferae but differs in the thick wall present at near the base of the conidiomata, with two types of conidiogenous cells, these ranging from cylindrical with an elongated slimy neck to ampulliform and having a wider base, and lacking paraphyses. The morphology of this new species is described and illustrated.

During surveys of fungi occurring on coffee plants, we collected a species of Neohendersoniaceae on dead twigs of an Arabica coffee plant in Pu'er, Yunnan Province, China. Phylogenetic analyses of combined SSU, LSU, ITS, rpb2, and tef gene sequences confirmed that our fungus is a distinct new species within Crassiparies. Morphological characteristics also support this taxon to be a novel species in Crassiparies. Full description, photo plate, and a phylogenetic tree to show the placement of the new species in Crassiparies are provided.

查看更多>>摘要：A study based on morphological and molecular (ITS/ETS nrDNA) data presents a taxonomic revision of the genus Elwendia in Tajikistan and neighbouring countries with a special attention to the E. kuhitangi ??? E. salsa complex. As a result, three new species of Elwendia from Tajikistan are described: E. darwasica, E. schistosa, and E. varsobica. Elwendia varsobica differs from all of these species by broad ovate-lanceolate sheaths of stem leaves and dorsally compressed mericarps. Elwendia darwasica and E. schistosa differ from E. kuhitangi and E. salsa by erect or slightly spreading styles of fruits. Improved morphological descriptions of E. kuhitangi and E. lindbergii as well as a new identification key for all Elwendia species known from Tajikistan and adjacent regions are provided. The distribution of E. lindbergii and E. capusii is expanded: E. lindbergii is reported for the first time from Tajikistan and E. capusii from Afghanistan.
查看更多>>摘要：Two coelomycetous strains with appendage-bearing conidia were collected from diseased leaves of Celtis sinensis (Urticales, Ulmaceae) and Indocalamus tessellatus (Poales, Poaceae) in Yunnan and Hainan provinces, southern China. Both strains produced 4-septate conidia with concolourous median cells, which were similar to Pestalotiopsis and Pseudopestalotiopsis. Based on the comprehensive morphological comparison and multi-gene (ITS, tub2, tef1) phylogenetic analyses, the strains were found to belong to Pseudopestalotiopsis. They represent two novel taxa and are described as Pseudopestalotiopsis
查看更多>>摘要：A new poroid fungus in the family Steccherinaceae, Antella tibetica sp. nov., is described from southwest China based on morphology, and phylogenetic analysis. The species was found in the Tibet Autonomous Region of southwest China, growing on angiosperm wood of a low decay stage. It is characterized by an annual growth habit, resupinate basidiocarps with buff yellow to yellowish brown pores, 0.5???1.5 per mm, a dimitic hyphal system composed of clamped generative hyphae and subicular skeletal hyphae encrusted with fine crystals, abundant gloeocystidia that are variable in shape, and oblong-ellipsoid basidiospores. The phylogenetic analysis based on ITS + nLSU rDNA sequences shows that A. tibetica nests in Antella, forming a monophyletic lineage with strong support (100 % BS, 100 % BP, 1.00 BPP). The differences between A. tibetica and other members of the genus are discussed. A key to accepted species of Antella is provided.
