Dead leaves of Musa sp. (banana) were collected in northern Thailand during an investigation of saprobic fungi. Preliminary morphological observations revealed that three specimens belong to Dictyoarthrinium. Phylogenetic analyses of combined SSU, LSU, ITS and tef1-α sequence data revealed that Dictyoarthrinium forms a clade in Didymosphaeriaceae (Massarineae, Pleosporales, Dothideomycetes) sister to Spegazzinia. Based on contrasting morphological features with the extant taxa of Dictyoarthrinium, coupled with the multigene analyses, Dictyoarthrinium musae sp. nov. is introduced herein. Our study provides the first detailed molecular investigation for Dictyoarthrinium and supports its placement in Didymosphaeriaceae (Massarineae, Pleosporales, Dothideomycetes). Previously, Dictyoarthrinium was classified in Apiosporaceae (Xylariales, Sordariomycetes).

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.

A New Species

Poaceascoma aquaticum sp. nov. (Lentitheciaceae) was found on decaying bamboo submerged in a freshwater stream in northern Thailand. The new species is introduced based on its unique morphology and phylogeny. Poaceascoma aquaticum is characterized by black, semi-immersed or erumpent, papillate ascomata, bitunicate, cylindrical to cylindric-clavate, short pedicellate asci and filiform, pale brown to brown ascospores. Phylogenetic analyses of combined LSU, SSU and RPB2 sequence data shows that Poaceascoma aquaticum forms a robust clade with P. helicoides in the family Lentitheciaceae (Pleosporales). Poaceascoma aquaticum is described, illustrated and compared with related taxa.

First Time

Endophytes are fungi associated with plants without causing symptoms, and they are quite diverse and have enormous potential for production of important secondary metabolites for the pharmaceutical industry. In this study, we report for the first time fungi (both endophytes and saprobes) from Antidesma madagascariense, a medicinal plant in Mauritius, in view of identifying potential candidates for screening of fungi for pharmaceutical importance. In addition the phylogenetic placement of fungi recovered from leaves samples was investigated based on rDNA sequence analysis. Most commonly isolated fungi were related to Aspergillus, Guignardia, Fusarium, Penicillium, Pestalotiopsis, and Trichoderma. Phylogenetic analyses revealed that fungi recovered belong to 5 different fungal lineages (Hypocreaceae, Trichocomaceae, Nectriaceae, Xylariaceae, and Botryosphaeriaceae). DNA data from the ITS regions were reliable in classification of all recovered isolates up to genus level, but identification to an exact species name was not possible at this stage. Despite criticisms pertaining to the use of ITS sequence data in molecular systematics, our approach here provides an opportunity to justify the reliability of ITS sequence data for possible identification and discovering of evolutionary scenarios among isolates that do not sporulate under cultural conditions.

A new record of Crambionella stuhlmanni is reported from the east coast of South Africa. The material is described using quantitative morphological data, and mitochondrial (CO1) and nuclear (ITS-1) sequence data. The species can be diagnosed by a combination of morphological features including the presence of conical projections on velar lappets, the absence of orbicular appendages among mouthlets and the short length of the terminal club on the oral arm. Mitochondrial sequence data unambiguously delineate C. stuhlmanni as a separate species from C. orsini, and phylogenetic analyses support its placement within the monophyletic genus, Crambionella.

A new fungus, Muyocopron thailandica, collected from a dead plant sample in northern Thailand, is described and compared with other described species of Muyocopron. Multi-gene phylogenetic analyses based on LSU and ITS sequence data indicated that M. thailandica forms a distinct lineage within the genus Muyocopron, and is closely related to M. castanopsis and M. lithocarpi. Muyocopron thailandica differs from these two species in having ellipsoid to subcylindrical asci, with a very short and thin pedicel and oval to obovoid ascospores. Asci and ascospores of M. thailandica are larger than those of M. castanopsis and M. lithocarpi. Morphological description and a detailed illustration of the new species are provided.

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.

During our survey of the diversity of woody litter fungi in China and Thailand, three Hermatomyces species were collected from dead woody twigs of Dipterocarpus sp. (Dipterocarpaceae) and Ehretia acuminata (Boraginaceae). Both morphology and multigene analyses revealed two taxa as new species (Hermatomyces turbinatus and H. jinghaensis) and the remaining collections as new records of H. sphaericus. Hermatomyces turbinatus is characterized by 1) dimorphic conidia, having circular to oval lenticular conidia and 2) turbinate conidia consisting of two columns with two septa composed of 2–3 cells in each column. Hermatomyces jinghaensis is characterized by dimorphic conidia, having circular to oval lenticular conidia and clavate or subcylindrical to cylindrical conidia and consisting of one or two columns with 6–8 cells in each column. Phylogenetic analyses of combined LSU, ITS, tub2, tef1-α and rpb2 sequence data supports the placement of these new taxa within Hermatomycetaceae with high statistical support.

A non-lichenized Trypetheliaceae species was collected and isolated from dead bark of Pandanus tectorius in Chanthaburi, Thailand. Morphological features of the fungus places it in the genus Novomicrothelia. Phylogenetic analyses of LSU sequence data showed that the fungus clustered together with Novomicrothelia oleosa and formed a well-supported basal clade in the family Trypetheliaceae. The fungus is phylogenetically distinct from the type species N. oleosa, and herein we introduce this taxon as Novomicrothelia pandanicola sp. nov. The new species shares similar ascomatal morphology and trabeculate pseudoparaphyses with N. oleosa, but differs in its muriform ascospores with a gelatinous sheath. Novomicrothelia pandanicola is described, illustrated and notes on its phylogenetic placement are provided.

Lophiostoma vaginatispora comb. nov. was collected from submerged wood in a stream in Northern Thailand. The species is characteristic by immersed to erumpent ascomata, with slot-like ostioles, with long, branched and numerous periphyses, an unequally thick peridium where the upper part is narrower than the lower part, and 1-septate, narrowly fusiform ascospores with a thick surrounding papilionaceous sheath. The placement of this species in Lophiostoma is based on morphological characters and phylogenetic analyses of the partial nuclear ribosomal 18S small subunit and 28S large subunit DNA sequence data. Lophiostoma vaginatispora is distinguished from other Lophiostoma species in possessing a wide papilionaceous sheath.
