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.

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.

A New Species

Xanthagaricus siamensis, a new species in the family Agaricaceae, was discovered in northern Thailand and is here introduced based on its morphological features and molecular data. It is characterized by small to medium-sized basidiomata, a convex to plano-convex with depressed center pileus when mature, the presence of greyish orange to violet-brown fibrillose squamules on the pileus, lamellae that start out white, change to pinkish white when damaged, then change to dull green with age. Additionally, the annulus is fugacious, and the pileipellis is recognized as a cutis which morphologically distinguishes it from all other known Xanthagaricus. Phylogenetic analysis of the internal transcribed spacer region (ITS) and the large subunit of the nuclear ribosomal DNA (nrLSU) sequence data indicated that the three specimens of X. siamensis form a distinct lineage within Xanthagaricus, and they formed a well-supported clade representing the genus Xanthagaricus. Detailed illustrations of macro- and micro-morphological characteristics and descriptions are provided, as well as other relevant molecular evidence.

A New Species

Obba thailandica sp. nov. is described and illustrated from northern Thailand based on evidence from morphological characteristics and molecular data. The species produces annual, resupinate, white and waxy fresh basidiocarps, which become bone hard when dry, and has a very thin subiculum (< 0.1 mm), tomentose tube openings, weakly dextrinoid hyphae, variably shaped cystidioles, thin-walled and subglobose to globose basidiospores (4.8–5.8 × 4–4.9 μm) mostly with a large guttule and grows on charred pine wood. The new taxon is rather similar to O. rivulosa in both morphology and ecology, but O. rivulosa has fragile tubes when dry, a thick subiculum (up to 1 mm wide), smooth tube openings, indextrinoid hyphae, rhomboidal to irregular rosettes crystals on the tramal hyphae and long basidia (16–27 × 6–9.5 µm). In the phylogeny inferred from an ITS dataset, the new species forms a distinct lineage in the Obba clade and is closely related to O. rivulosa.

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.

Ganoderma is a cosmopolitan genus of mushrooms, which can cause root and butt rot diseases on many tree species. Members of this genus are particularly diverse in tropical regions. Some Ganoderma spp. are medicinally active and therefore are used to treat human diseases or as a dietary supplement. In this study, three Ganoderma strains were collected in tropical southern Thailand. Phylogenetic analyses of combined ITS, LSU, TEF1α and RPB2 sequence data indicated that the three strains grouped in a distinct lineage within laccate Ganoderma. One strain was collected from Surat Thani Province clustered in the G. casuarinicola clade with high statistical support (MLBS = 100% / MPBS = 98% / PP = 0.96), while the other two strains of Ganoderma, collected from Nakhon Si Thammarat Province, formed a distinct well-supported clade (MLBS = 100% / MPBS = 100% / PP = 1.00) and are described here as a new species. Ganoderma casuarinicola is reported here as a new record to Thailand. Morphological differences of the two taxa and their closely related taxa are discussed. Colour photographs of macro and micro morphological characteristics and a phylogenetic tree to show the placement of the new record and new species are provided.

In this paper, we report a new asexual-morph taxon belonging to the family Cordycipitaceae (Hypocreales), which is associated with a sexual morph of an ophioceras-like taxon on submerged wood collected from Baoshan, Yunnan, China. Morphologically, this new taxon is similar to known asexual morphs of Lecanicillium and characterized by conidiophores arising from hyaline hyphae, with gregarious, ellipsoid to ovoid, aseptate conidia. Phylogenetic analyses of a combined LSU, SSU, tef1-α and ITS sequence dataset positions our taxon in Cordycipitaceae and close to Lecanicillium sp. (CBS 639.85) and L. primulinum. Lecanicillium subprimulinum is introduced as a new species with support from molecular data.

Amanita submelleialba sp. nov. in section Amanita, is described from northern Thailand based on both multi-gene phylogenetic analysis and morphological evidences. It is characterized by having small to medium-sized basidiomata; a yellow to yellowish pale pileus covering pyramidal to subconical, white to yellow white volval remnants; globose stipe base covered conical, white to yellow white volval remnants; fugacious subapical annulus; and absent clamps. Multi-gene phylogenetic analyses based on partial nuclear rDNA internal transcribed spacer region (ITS), partial nuclear rDNA larger subunit region (nrLSU), RNA polymerase II second largest subunit (RPB2), partial translation elongation factor 1-alpha (TEF1-α) and beta-tubulin gene (TUB) indicated that A. submelleialba clustered together with A. elata and A. mira, but represented as a distinct lineage from other extant species in section Amanita. The detailed morphological characteristics, line-drawing illustration and comparisons with morphologically similar taxa are provided.
