During the survey of pathogenic fungi on medicinal plant leaves in Yunnan Province, China, two Cladosporium-like taxa were isolated from leaf spots of Paris polyphylla. Based on morphological characteristics and phylogenetic analysis of combined ITS, TEF1-α and ACT genes, two new species were discovered. Two new species Cladosporium yunnanensis and C. paris are introduced, the detailed descriptions and illustrations are provided. Morphology of the two new species is compared with other related Cladosporium species. This study widens the host diversity of the genus Cladosporium.

Dendrocalamus Membranaceus

The genus Phyllachora is the largest genus in the family Phyllachoraceae. Phyllachora species are obligate biotrophic fungi with a tropical distribution. During our field surveys in Yunnan province of China, fifteen graminicolous Phyllachora species were collected. Multi-locus phylogenetic analyses of ITS and LSU together with morphological characteristics, two new species, Phyllachora dendrocalami-membranacei sp. nov. on Dendrocalamus membranaceus and P. dendrocalami-hamiltonii sp. nov. on D. hamiltonii are described and illustrated. Phyllachora dendrocalami-membranacei is characterized by its dump-bell to ellipsoidal to ovoid ascospores (15–25 × 5–11 μm) while P. dendrocalami-hamiltoniicola is distinguished by its dump-bell to ellipsoidal ascospores (15–30 × 8–12 μm).

Small Genus

Acervus is a small genus in Pyronemataceae. Most of the species in this genus have been recorded from China. In the present study, two species of Acervus from Yunnan Province, in southwestern China, were investigated by using morphology and DNA sequence data. This paper introduces two new species A. stipitatus and A. globulosus, with morphological descriptions, and compares them with morphologically similar taxa. Multi-gene phylogenetic analyses inferred from 28S, TEF1 and RPB2 sequence data strongly support the lineages for taxa of Acervus, corresponding to morphological features. We also provide a summarized comparison of the important morphological characteristics of Acervus species.

Two new species of the ant genus Myrmecina Curtis, 1829 are described and illustrated based on the worker and queen castes collected in Sumatra, Indonesia under the names M. andalas sp. nov. and M. nitidiuscula sp. nov. Each species displays unique morphological characteristics. Myrmecina andalas sp. nov. is characterized by a combination of the following characteristics: head dorsally sculptured, with the ventrolateral area smooth and shiny; propodeal spine short, triangular, pointing dorsad and with a broad base; propodeal declivity vertical, with the posterodorsal angle almost 90°. Myrmecina nitidiuscula sp. nov. is characterized by a combination of the following characteristics: head dorsum largely smooth and shiny; propodeal spine triangular and pointing posteriad, with a very broad base. Updated key to Myrmecina species of Sumatra is given.

Two new species belonging to the precious coral genus Corallium were collected during a series of exploratory cruises to the New England and Corner Rise Seamounts in 2003–2005. One red species, Corallium bathyrubrum sp. nov., and one white species, C. bayeri sp. nov., are described. Corallium bathyrubrum is the first red Corallium to be reported from the western Atlantic. An additional species, C. niobe Bayer, 1964 originally described from the Straits of Florida, was also collected and its description augmented.

Twenty-one strains of Arthrinium were cultured from leaf samples of ten medicinal plant hosts in Yunnan Province, China. Morphological and multi-locus ITS+TUB+TEF1 sequence analyses revealed that the strains represented two previously described species (A. paraphaeospermum and A. rasikravindrae) and two new species: Arthrinium cordylines, which produces subglobose conidia that are shorter and wider than A. aureum but larger than A. hydei, and Arthrinium pseudomarii, which produces subglobose to ellipsoid conidia narrower than A. hispanicum, A. marii, and A. mediterranei.

Summary Two new Neomisticius species, typologically and phylogenetically close to each other, are described and illustrated from dead Quercus trees and an ambrosia beetle, Platypus quercivorus. The two species share some stylet morphological characteristics, namely, they both possess a long conus occupying more than half of the total stylet length, a long crustaformeria composed of more than 160 cells (eight rows of more than 20 cells each), and a short and broad female tail with a digitate tip. They are distinguished from each other by N. variabilis n. sp. having a wide, spindle-shaped male bursa with a blunt terminus and N. platypi n. sp. having an oval bursa with a rounded terminus. In addition, the males and females of both species have three large rectal glands and the posterior end of the male testis (distal end of the vas deferens) bears three cells that seemingly function as a valve between the vas deferens and the cloacal tube. These characteristics have not been reported in other tylenchids. Currently, the genus contains only three species: the two new species and N. rhizomorphoides, which has a normal stylet with a short conus, a short crustaformeria, and lacks rectal glands and valve cells in the vas deferens. Therefore, the two new species are readily distinguished from N. rhizomorphoides and, based on the previous definition, may even represent a new genus. However, considering their phylogenetic closeness and biological similarities (e.g., association with ambrosia beetles), the generic definition of Neomisticius was emended to include these new species.
