However, based on cultural and morphological characteristics strain KNUF-23-236 differs from S. aurantiacum and S. album by having white-to-yellow colonies without reddish pigmentation, smaller hyphae (1.4-3.4 μm vs. 1.6-4.8 μm and 3.2-8.0 μm, respectively), arthrospores that transition from hyaline to brown rather than remaining consistently hyaline, and oval, septate chlamydospores that form singly or in chains, without branching. Furthermore, the phylogenetic trees constructed using the ITS sequence alone, the concatenated ITS and LSU sequences, and the combined sequences of three loci (ITS, SSU, and RPB2) confirmed a distinct phylogenetic position of KNUF-23-236 within the genus Scytalidium. Based on a combination of phylogenetic and morphological evidence, strain KNUF-23-236 is identified as a novel species of the genus, for which the name Scytalidium terrigenum sp. nov. is proposed.","PeriodicalId":18825,"journal":{"name":"Mycobiology","volume":"53 3","pages":"295-304"},"PeriodicalIF":1.6,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11956102/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the fungi was found to produce a mycotoxin called zearalenone, which is known to be a reproductive system disruptor. The presence of zearalenone was further confirmed using an authentic standard and a series of tandem mass spectrometry approaches. ITS sequencing identified the zearalenone-producing endophytic fungus as Talaromyces, showing sequence similarity to various species within this genus.

The strain KNUF-22-094T stands out among other Microascus species due to its distinctive conidiogenous cells and conidial size ranges. The conidiogenous cells of KNUF-22-094T measured 2.3-4.3 × 2.0-3.6 µm, notably smaller than those of M. rothbergiorum (7.5-11.5 × 2.5-4.5 µm), M. sparsimycelialis (5.0-10.0 × 3.0-5.0 µm), which is considerably larger in both dimensions. For the conidial structures, conidia measured 2.6-4.8 × 2.6-4.4 µm, falling within a distinct range that is smaller than those of M. rothbergiorum (4.0-5.5 × 3.5-4.5 µm), M. verrucosus (5.0-7.0 × 4.5-6.0 µm), and M. restrictus (4.5-6.0 × 4.0-5.5 µm), but comparable in size to M. murinus, which tends to be more elongated (4.0-6.0 × 1.5-1.9 µm). The phialides of KNUF-23-321CT are globose, with a notably broad length range of 3.7-22.5 µm and a width of 0.9-1.5 µm, making it one of the most variable in length compared to species like T. album (3.5-10 µm) and T. endophyticum (1.3 ± 0.2 µm, 4.1 µm on average).

The infrageneric classification of the genus Penicillium has been studied with comparison of morphological and phylogenetical features, derived into two subgenus, 32 sections, and 89 series. In this study, 11 fungal strains were isolated from freshwater environments, plant litter, and nearby substrates in Korea and were identified as previously unreported species. The internal transcribed spacer (ITS) regions, β-tubulin (BenA), calmodulin (CaM), and RNA polymerase II subunit (RPB2) genes were analyzed for phylogenetic analyses. A neighbor-joining tree was then constructed using the concatenated DNA sequences, and the strains were compared with closely related species of the genus Penicillium.

Recent comprehensive studies on Helvella have revealed that some Helvella species exhibit endemic traits and that many morphologically similar, cryptic species are phylogenetically distant. In this study, 202 Korean Helvella specimens collected between 1986 and 2023 were reevaluated through morphological analysis and phylogenetic characterization using barcode sequences, including nrLSU (nuclear Large Subunit Ribosomal DNA), hsp90 (Heat Shock Protein 90), and ITS (Internal Transcribed Spacer). The investigation confirmed the presence of at least 35 phylogenetic species in Korea. Among these, eight species (H. atroides, H. fistulosa, H. liquii, H. lobata, H. rugosa, H. subglabroides, H. sublactea, H. varia) were identified as previously unrecorded species in Korea, and seven new species (H. densipila, H. flavopus, H. macrospora, H. griseobrunnea, H. pseudolobata, H. parviflava, H. suborentitomentosa) were discovered. Of the 13 previously recorded Korean Helvella species, only three (H. ephippioides, H. macropus, H. orienticripsa) were confirmed, while the remaining ten species (H. acetabulum, H. atra, H. compressa, H. costifera, H. crispa, H. elastica, H. sublicia, H. fibrosa, H. lacunosa, H. pezizoides) were not detected in the samples studied.
