Decaying Wood

Asexual morph members of Tetraplosphaeriaceae (Pleosporales, Dothideomycetes) are generally hyphomycetes and usually found as saprobes occurring on various hosts in lentic habitats. Two isolates of a novel species, Tetraploa aquatica sp. nov., was collected from submerged decaying wood in Dulong river and a stream of Gaoligongshan mountain in Yunnan Province, China. The new species is characterized by short-cylindrical conidia, composed of 4-euseptate, short-cylindrical vertical columns which are verrucose at the base and with 4-setose vertical septate appendages. Tetraploa aquatica can be easily distinguished from other Tetraploa species by their columns which are 2–3-septate, aguttulate, vertical, setose appendaged which tend to remain parallel to one another apically. Phylogenetic analyses of combined LSU, ITS and SSU sequence data support its natural placement in Tetraploa. Detailed description and illustrations of this species and comparisons with other morphologically similar taxa in Tetraploa are provided.

Distinct Lineage

Lasiodiplodia species are commonly as endophytes, saprobes and pathogens in tropics and subtropics. During an investigation of Botryosphaeriaceae in Thailand, two Lasiodiplodia taxa were isolated. Morphological characteristics and phylogenetic analyses based on combined ITS, tef and tub2 sequence data support the establishment of a novel species, Lasiodiplodia chiangraiensis, isolated from woody hosts. Lasiodiplodia chiangraiensis is phylogenetically close to L. iraniensis and L. thailandica, but represents a distinct lineage. The new species could be distinguished from extant Lasiodiplodia species by its mature conidial dimensions. A detailed description and illustration are provided, as well as an updated phylogenetic tree (ITS, tef and tub2) including all species (with available molecular data) of Lasiodiplodia. In addition, the accepted genera in Botryosphaeriaceae based on recent studies are given.

Lentithecium cangshanense sp. nov. (Lentitheciaceae, Dothideomycetes), was found on submerged decaying wood in a freshwater stream in Yunnan Province, China. The species is characterized by its black, semi-immersed to superficial, globose ascomata, cylindrical or obclavate, short pedicellate, bitunicate asci and bi-seriate, fusiform, 1-septate, yellowish to brown ascospores. Phylogenetic analyses of combined LSU, SSU and RPB2 sequence data show that L. cangshanense belongs in the family Lentitheciaceae, order Pleosporales and is a distinct species in the genus. The new species is introduced with an illustrated account and compared with morphologically and phylogenetically similar species.

During a survey on diversity of freshwater fungi along a north-south latitudinal gradient in Asia, three fresh specimens of Minimelanolocus were collected from submerged wood in streams in northwestern Yunnan Province, China. Based on their distinct morphological features and phylogenetic analyses of combined ITS, LSU and SSU sequence data, Minimelanolocus nujiangensis and M. clavatus are described as new species and M. submersus was recollected from Yunnan, China. Illustrations and descriptions with notes of the three species are provided. This study increases the known diversity of Minimelanolocus and enriches freshwater fungal resources.

A New Species

A new species of the genus Gonyosoma Wagler is described from Yunnan Province, China. The new species closely resembles G. prasinum (Blyth), but it is differentiated from the latter species by the following characters: precloacal plate divided, iris blue and inside of mouth greyish-white in life. Based on phylogenetic analyses of mitochondrial cytochrome b sequence data, the new species is recovered as the sister species to G. prasinum by Bayesian Inference and Maximum Likelihood analyses. The uncorrected pairwise distance between the new species and other species of the genus Gonyosoma ranged from 11.78% to 17.07% calculated using the mitochondrial cytochrome b sequence. This discovery increases the number of Gonyosoma species to seven.

A New Species

A new orchid species, Cymbidium yunnanensis (Orchidaceae; Epidendroideae; Cymbidieae), from Yunnan Province, China, is described and illustrated. Based on morphological and molecular analyses, we demonstrate that this new species is similar to C. floribundum, but it differs in its smaller size, leaves 5–15 cm, shorter scape, white flowers with pale purplish markings on its sepals and petals, lip with purplish red blotch, petals narrowly falcate oblong and lip midlobe nearly round with column foot 1.5–2.0 mm long. Phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) DNA sequence data support C. yunnanensis as a new species.

In this study, five aquatic hyphomycetous taxa were collected and isolated from submerged wood in Lancang River located in the northwestern Yunnan Province of China. Phylogenetic analyses based on combined LSU, ITS, tef1α and rpb2 sequence matrix indicated that those five taxa belonging to Distoseptispora (Distoseptisporaceae), and they can be recognized as four species which two are introduced as new species (Distoseptispora euseptatensis and D. yunnanensis) and two are identified as D. aquatica and D. tectonae. Two isolates of the new species Distoseptispora euseptatensis formed a distinct clade among Distoseptispora species (basal to D. suoluoensis and D. bambusae) with good support (ML 100%, MP 100%, BI 1.00 PP). Distoseptispora yunnanensis clustered together with D. euseptatensis, but they are difference in the size of conidiophore and conidia. Corresponding illustrations, descriptions and phylogenetic evidences are provided to justify the placement of our newly collected Distoseptispora taxa.

During a survey of keratinolytic fungi in China, three Cunninghamella strains were isolated. Phylogenetic analyses of ITS and ITS+LSU+EF-1α sequence data showed that these strains constitute a new species related to C. blakesleeana, C. bigelovii, C. multiverticillata and C. phaeospora. The new species differs from C. multiverticillata and C. phaeospora in the shape and size of its teminal and lateral vesicles and can be distinguished from C. blakesleeana and C. bigelovii by the absent of zygosporangia, and the shape and size of it sporangioles. The results of phylogenetic and morphological analyses indicate that the three strains are a new species of Cunninghamella. Descriptions and illustrations of this novel species are provided in this paper.

This study embodies description of a novel Monochaetia species, from dead leaf of a Quercus sp. collected from Lijiang in Yunnan Province, China. Morphologically, it conforms to the characters of Monochaetia by presence of single apical and basal appendage on the conidia. The new species forms a sister clade to M. ilexae in the combined LSU-ITS and TUB2 sequence data based phylogenetic analyses and remain distinct from the latter species in having larger conidia, long apical appendage, long basal appendage and long conidiogenous cells. Therefore, we introduce Monochaetia sinensis as a novel taxon with a comprehensive description and illustration.

Conioscypha is an asexual morph genus placed in the family Conioscyphaceae. During our study of brown-spored hyphomycetes, a new taxon C. tenebrosa was found on decaying wood collected in Guizhou Province, China. The new species is characterized by having micronematous, hyaline conidiophores which are often reduced to conidiogenous cells, with a cup-shaped, percurrently developed, multi-collaretted phialide, and globose to subglobose, obovoid conidia with broadly rounded apex and subtruncate base. The phylogenetic analysis of combined LSU, SSU, ITS and RPB2 sequence data showed that isolates of C. tenebrosa are phylogenetically distinct from other species. Conioscypha tenebrosa sp. nov. is therefore introduced here with a description and morphological illustration. Taxonomic notes and a morphological comparison of Conioscypha species are provided.
