In total, seven specimens exhibited distinctive morphological traits that, when compared with historical records, confirm their identification as A. ampullifer-particularly noted for its affinity to dipteran hosts.

This overlooked fungus is phylogenetically most closely related to the species A. pyralidarum, A. laosensis, and some other species mostly associated with adult moths. It demonstrates a unique morphological signature with monoblastic phialides forming a layer on the surface of synnemata and produces long, cylindrical, chain-forming conidia.

Although 18S-ITS-28S nuc rDNA sequences obtained from these sporocarps showed high sequence variability, phylogenetic analyses based on 18S-ITS-28S, the largest subunit of the RNA polymerase II (rpb1) gene, and concatenated sequences of the two loci convincingly demonstrated the identity of these sporocarps to E. japonicum. Importantly, the 18S-ITS-28S+rpb1 analyses highlighted the key role of rpb1 sequences in reconstructing the phylogenies of Glomeromycota taxa with strongly divergent rDNA sequences. Upon inoculation with sporocarpic spores, E. japonicum formed mycorrhiza with arbuscules and vesicles, which was not confirmed in the original description of the species. Comparisons of E. japonicum 18S sequences with Glomeromycota DNA sequences available in a public database indicated that E. japonicum is a cosmopolitan species and is mainly associated with plants in natural habitats such as grasslands, shrublands, and forests. Phylogenetic analyses also confirmed the autonomy of E. crypticum, another known species of the genus Epigeocarpum whose sporocarps were originally found in Brazil.","PeriodicalId":18780,"journal":{"name":"Mycoscience","volume":"65 6","pages":"270-277"},"PeriodicalIF":1.5,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12120553/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199641","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}

Currently, mainstream artificial cultivation methods for this mushroom typically use synthetic logs. However, browning of the stem’s interior (stem browning) has been observed during the cultivation in some L. edodes strains. Although browning does not affect the taste or other qualities of the mushroom, it gives consumers a perception of “poor quality”, and is a major challenge for producers. To identify the genes responsible for stem browning in this mushroom, we performed differential gene expression analysis during stem browning development and quantified it using real-time PCR. Our results indicated that certain oxidoreductases, such as tyrosinase and laccase, were significantly upregulated during the progression of stem browning.
