Three new fungal species in the (, ) associated with plants were collected in Thailand. Morphological characterisation and phylogenetic analyses based on multi-locus sequences of LSU, and showed that two species belong to and occupies a unique clade and is proposed as a novel genus in and share the morphological characteristic of having cylindrical to clavate stromata arising from seeds. produces perithecial plates and occurs on a leaf sheath of an unknown panicoid grass.

Fungal pathogens occurring on in Thailand.

Two new fungal genera and six species occurring on insects in the orders Orthoptera and Phasmatodea (superorder Orthopterida) were discovered that are distributed across three families in the . Sixty-seven sequences generated in this study were used in a multi-locus phylogenetic study comprising SSU, LSU, , and together with the nuclear intergenic region (IGR). These new taxa are introduced as , , , , and .

Revisiting and the description of new species from Thailand.

Over the last two decades the molecular phylogeny and classification of has been widely studied. Despite these efforts to understand this enigmatic genus, the basal lineages in are still poorly resolved. In this study, a phylogenetic framework is reconstructed for the focusing on through increased taxon-sampling using five genomic loci (SSU, LSU, 2) and the barcode marker ITS rDNA.

Diversity of on moths (Lepidoptera) in Thailand.

is a genus of invertebrate-pathogenic fungi from the family Cordycipitaceae (Ascomycota, Hypocreales). Its species occurs on two different types of hosts, spiders and insects, and in the latter case specifically Lepidoptera adults. Three new species of , , , and occurring on adult moths from Thailand are proposed based on the differences of their morphological characteristics and molecular data.

Novel and interesting spp. (, ) with superficial perithecia from Thailand.

is a heterogeneous, species-rich genus in the order (, ) that includes invertebrate-pathogenic taxa. In this study, seven new species in producing superficial perithecia infecting various insect hosts (Lepidoptera, Hemiptera) are described from Thailand - and . Phylogenetic analyses based on multigene loci comprising the large subunit of the ribosomal DNA (LSU), partial sequences of elongation factor 1-alpha (TEF) and the largest and second largest subunit of the RNA polymerase (RPB1, PRB2) strongly support these new species of in the .

Disentangling cryptic species with isaria-like morphs in Cordycipitaceae.

A new genus and eight new species, all with isaria-like phialides, are described in Cordycipitaceae from Thailand. The new genus, Samsoniella, is segregated from Akanthomyces based on morphological and molecular evidence. Samsoniella differs from Akanthomyces in producing orange cylindrical to clavate stromata with superficial perithecia and orange conidiophores with isaria-like phialides and white to cream conidia.

Cordybislactone, a stereoisomer of the 14-membered bislactone clonostachydiol, from the hopper pathogenic fungus Cordyceps sp. BCC 49294: revision of the absolute configuration of clonostachydiol.

Cordybislactone (3), a new stereoisomer of the 14-membered bislactone clonostachydiol, together with its open ring analog (4), was isolated from the hopper pathogenic fungus Cordyceps sp. BCC 49294. The relative and absolute configurations of 3 were determined by chemical derivatizations, including the modified Mosher's method.

New species of Ophiocordyceps unilateralis, an ubiquitous pathogen of ants from Thailand.

Torrubiellone E (1), a new N-hydroxypyridone alkaloid, was isolated from the spider pathogenic fungus Torrubiella longissima BCC 2022, together with the known compounds, torrubiellones A (2) and B (3), and JBIR-130 (4). Compound 1 exhibited antimalarial activity against Plasmodium falciparum K1 with an IC5 value of 3.2 microg/mL, while it also showed weak cytotoxic activities.

Molecular phylogenies reveal host-specific divergence of Ophiocordyceps unilateralis sensu lato following its host ants.

Ophiocordyceps unilateralis (Hypocreales, Ascomycetes) is an entomopathogenic fungus specific to formicine ants (Formicinae, Hymenoptera). Previous works have shown that the carpenter ant Camponotus leonardi acts as the principal host with occasional infections of ants from the genus Polyrhachis (sister genus of Camponotus). Observations were made on the permanent plots of Mo Singto, Khao Yai National Park of Thailand according to which O.

Ophiocordyceps halabalaensis: a new species of Ophiocordyceps pathogenic to Camponotus gigas in Hala Bala Wildlife Sanctuary, Southern Thailand.

Several fungal pathogens of ants have been reported as members of the family Ophiocordycipitaceae in the order Hypocreales. Surveys in the south of Thailand have shown specimens showing characteristics that are morphologically similar to Ophiocordyceps unilateralis, a very common ant pathogen, by producing a lateral pad on one side of the stroma and producing whole ascospores.
