A New Species

Ant-pathogenic fungi are mainly found in the Ophiocordycipitaceae, rarely in the Cordycipitaceae. During a survey of entomopathogenetic fungi from Southwest China, a new species, Cordyceps yinjiangensis, was isolated from the ponerine. It differs from other Cordyceps species by its ant host, shorter phialides, and smaller septate conidia formed in an imbricate chain. Phylogenetic analyses based on the combined datasets of (LSU+RPB2+TEF) and (ITS+TEF) confirmed that C. yinjiangensis is distinct from other species. The new species is formally described and illustrated, and compared to similar species.

During a survey of entomopathogenetic fungi from Southwest China, a new species, Paracremonium lepidopterorum was isolated from a pupa. It differs from other Paracremonium species by its shorter cylindrical phialides and absence of slimy head of conidia and chlamydospores. Phylogenetic analyses based on the combined datasets of ITS+LSU+TUB confirmed that P. lepidopterorum is distinct from other species. The new species is formally described and illustrated, and compared to similar species.

A New Species

In northern South America, amphisbaenians are rarely seen among the herpetofauna.Thus, general knowledge about them is very poor. During a herpetological survey in 2012 at Casanare, Colombia, we found two specimens of an unusual Amphisbaena. A third specimen sharing the same morphotype labeled Amphisbaena sp. from Vichada department was found deposided in an Colombian reptile collection. Based on morphological analyses together with phylogenetic analyses of 1029 base pairs of the mitochondrial DNA (mtDNA), we describe a new species of Amphisbaena that inhabits in the Orinoquian region of Colombia. The new species is part of a phylogenetic clade together with A. mertensii and A. cunhai (central-southern Brazil), exhibiting a great genetic distance (26.1–28.9%) between the newly identified lineage versus those taxa, and versus the sympatric taxa A. alba and A. fuliginosa. Morphologically, this new Amphisbaena can be distinguished from their congeners by characters combination of number of preocloacal pores, absence of malar scale, postgenial scales and body and caudal annuli counts. Amphisbaena gracilis is on morphology grounds the most similar species. However, the new species can be distinguished from it by having higher body annuli counts, angulus ories aliegned with the edges of the ocular scales and center of frontal scales, less number of large middorsal segments of the first and second body annulus, and rostral scale visible from above. The description of this new Amphisbaena species points out the urgent need to increase the knowledge of worm lizards in Colombia

This study presents one telamonioid species new to science based on morphological characteristics and molecular phylogenetic analyses. Cortinarius khinganensis was collected from the Greater Khingan Mountains, Northeast China and it is characterized by hygrophanous, vivid brownish red and striate pileus, white universal veil, and subglobose spores. According to phylogenetic analyses results, C. khinganensis belongs to the section Illumini, which is a lineage distantly related from subgenus Telamonia sensu stricto. Detailed descriptions of the new species and the comparisons with morphologically similar species are provided. The phylogenetic relationships within the section Illumini are also discussed.

A new species of Gymnopus sect. Androsacei, namely, G. pallipes is described and illustrated based on morphological and molecular phylogenetic evidence. It is characterized by marasmioid basidiomata, a dark brown to reddish brown pileus becoming dull white to yellowish grey with age, whitish to pale yellow stipe and presence of rhizomorphs. Phylogenetic analyses support it as a new species within Gymnopus sect. Androsacei. The detailed morphological description, colour photos of basidiomata, and line drawings of microcharacters are presented and delimitation characters from similar species are discussed. A key to the known species of Gymnopus s. str. from China is also provided.

Euphorbia motuogensis M. T. Li, X. Z. Lan, H. P. Deng & W. L. Zheng, sp. nov., a new species from Motuo, Tibet, China, is described and illustrated here. It is closely similar to Euphorbia sikkimensis in having terete root, alternate leaves, well-developed pseudoumbellate inflorescence, cyathium, smooth and glaborus capsule, but Euphorbia motuogensis is clealy distinguishable by its pilose stems, involucral leaves color, secondary involucral leaves absent, cyathophylls number and color, and five similar glands. Furthermore, molecular phylogenetic analyses of sequences from both nuclear ribosomal ITS confirm that this species is distinct from morphologically similar species in this subgenus.

Ophiocordyceps is entomopathogenic and the largest studied genus in the family Ophiocordycipitaceae. Many species in this genus have been reported from Thailand. The first new species introduced in this paper, Ophiocordycepsglobiceps, differs from other species based on its smaller perithecia, shorter asci and secondary ascospores and additionally, in parasitising fly species. Phylogenetic analyses of combined LSU, SSU, ITS, TEF1α and RPB1 sequence data indicate that O.globiceps forms a distinct lineage within the genus Ophiocordyceps as a new species. The second new species, Ophiocordycepssporangifera, is distinguished from closely related species by infecting larvae of insects (Coleoptera, Elateridae) and by producing white to brown sporangia, longer secondary synnemata and shorter primary and secondary phialides. We introduce O.sporangifera based on its significant morphological differences from other similar species, even though phylogenetic distinction is not well-supported.

Amana baohuaensis is described and illustrated as a new species from Jurong City, Jiangsu Province, East China. The new species is morphologically similar to A. edulis, but differs from the latter by having three verticillate linear bracts, white or purple-red solitary flowers, and purplish-brown anthers. Phylogenetic analyses based on nuclear ITS, chloroplast matK and rps16 intron sequences confirmed that this new species is distinct from morphologically similar species.

Cornus sunhangii, a new species from Bari, at an elevation of 1988 m, in north Mêdog County, Tibet, China, is described. It is morphologically similar to C. capitata, but differs in the infructescence size, the length of the peduncle, the number of trichomes. The status of C. sunhangii, which is the earliest divergent in Cornus subg. Syncarpea, was confirmed by phylogenetic analyses using four chloroplast markers (atpB, rbcL, matK and ndhF). It has potential economic benefits, since similar species of Cornus have been used as food, oil, wood production and ornament.

Abstract— Plants from Brazilian campos rupestres usually present morphological strategies that allow them to survive in extreme environments. However, in Chamaecrista (Leguminosae, Caesalpinioideae), one of the most diverse genera in the campos rupestres, needle-like leaflets are rare. Reviewing the species that present such leaf morphology, we describe Chamaecrista acicularis, a new species from the Canastra Range, in the southwestern region of the state of Minas Gerais, Brazil. Phylogenetic analyses revealed that C. acicularis is not closely related to other quite similar needle-like leafleted species and that this trait evolved convergently. We also present comments on the phylogenetic relationships of needle-like leafleted species as well as the evolution of the leaflet amplitude, and a detailed description of C. acicularis alongside illustrations, photos, geographical distribution, a key to the needle-like leafleted species and taxonomic notes on similar species. Additionally, we expand the description of Chamaecrista strictifolia and present an informal conservation status for all needle-like leafleted species.

A New Species

During a survey of spider-pathogenic fungi from Southwest China, a new araneogenous species was found. The new species, Akanthomyces araneicola, differs from other species based on mostly smaller fusiform conidia (2.5–5.0 × 1.3–1.9 μm), mononematous conidiophores and, additionally, in parasitising a spider. Both the morphological identification and phylogenetic analysis of combined ITS, LSU, RPB1, RPB2 and TEF sequence data support A. araneicola as a new species in the genus Akanthomyces.
