During a survey of culturable fungi in the coastal areas of China, three new species of sect. were discovered and studied with a polyphasic taxonomic approach, and then named as sp. nov. (ex-type AS3.15900 = LN5H1-4), sp. nov. (ex-type AS3.16039 = TT2-4X3, AS3.16040 = TT2-6X3) and sp. nov. (ex-type AS3.16038 = 0801H2-2, AS3.16207 = ZZ2-9-3). In morphology, is unique in showing light yellow sclerotia and mycelium, sparse sporulation, restricted growth at 37 °C, irregular conidiophores, intercalary phialides and metulae, and pyriform to subspherical conidia. is distinguished by the fast growth on CYA and YES and slow growth on MEA at 25 °C, weak or absence of growth at 37 °C, biverticillate and monoverticillate penicilli, and ellipsoidal conidia. is characterized by abundant grayish-green conidia and moderate growth at 37 °C, the appressed biverticillate penicilli and fusiform, smooth-walled conidia. These three novelties were further confirmed by the phylogenetic analyses based on either the combined or the individual , , and internal transcribed spacer (ITS) sequences.

sp. nov., a novel basidiomycetous yeast species isolated from pine tree bark in Gyeongju, South Korea.

Int J Syst Evol Microbiol

Department of Food Science and Biotechnology, Kyung Hee University, Yongin 17104, Republic of Korea.

A novel yeast species, isolated from the bark of pine trees in Gyeongju, South Korea, and designated as KCTC 37304 (ex-type KACC 410729), is characterized by its genetic, morphological and physiological properties. Molecular phylogenetic analysis involving the D1/D2 domain of the 26S LSU rRNA gene and the internal transcribed spacer (ITS) region confirms that it belongs to the genus . In comparison to CBS:10065, the type strain of its closest relative, KCTC 37304 exhibits 8 nucleotide substitutions (~2.

Six strains (DMKU-SG26, DMKU-SG42, DMKU-SYM22, DMKU-RG41, DMKU-RX317 and DMKU-RGM25) representing a novel basidiomycetous yeast species were isolated from leaf surfaces of mangrove plants collected in Thailand. Pairwise sequence analysis indicated that the six strains either had identical nucleotide substitution in the D1/D2 domains of the large subunit (LSU) rRNA gene sequences or differed by one to three nucleotide(s). They also had identical or differed by one to five nucleotide substitution(s) in the internal transcribed spacer (ITS) regions.

Species classified in () include multiple entomopathogenic fungi. Numerous changes have recently occurred in the nomenclature of cordycipitaceous fungi due to the single naming system proposed for pleomorphic fungi in 2011. Species of are widely applied as herbal medicines, especially in Asian cultures.

Article Synopsis
  • The study investigates the phylogenetic relationships of two morphologically similar fungal genera within the Sordariomycetes, confirming they are congeneric and proposing new combinations for their classification.
  • New species were identified through molecular data, particularly using specific gene markers, as traditional morphology was insufficient for distinguishing them.
  • The research highlights the importance of the ascogenous system for genus identification and discusses the global diversity and biogeography of the genera, including the publication of whole-genome analyses to improve taxonomic standards.

Procedures, appointments and outcomes of the Fungal Nomenclature Session (FNS) of the XII International Mycological Congress (IMC12) are summarized, including the composition of the Fungal Nomenclature Bureau and the Nominating Committee of the IMC. Between 124 and 322 mycologists attended the three sessions of the FNS, at which formal proposals to amend Chapter F of the International Code of Nomenclature for algae, fungi, and plants were debated. The 15 proposals considered included eight "from the floor", five of which were withdrawn prior to the FNS.
