Five new species of Inosperma from China: Morphological characteristics, phylogenetic analyses, and toxin detection

Sai-Nan Li et al.

Summary: This study identified five new Inosperma species from China and conducted morphological and molecular phylogenetic analyses. The neurotoxin content in these five species was investigated using ultrahigh-performance liquid chromatography-tandem mass spectrometry, revealing variations in neurotoxin contents.

Foodborne illness caused by muscarine-containing mushrooms and identification of mushroom remnants using phylogenetics and LC-MS/MS

Sittiporn Parnmen et al.

Summary: The 9-year analysis of wild mushroom consumption in Thailand from 2010 to 2018 identified 61 patients from 14 cases showing mushroom poisoning, mainly from foraged mushrooms in the family Inocybaceae. Multi-locus sequence data revealed that the 26 clinical samples of mushrooms belonged to Inocybe, Inosperma and Pseudosperma, with LC-MS/MS detection confirming the presence of muscarine alkaloids in Inosperma and Pseudosperma. Ingestion of muscarine-containing mushrooms resulted in muscarinic symptoms, while Inocybe consumption led to gastrointestinal irritant effects.

Chemistry and Toxicology of Major Bioactive Substances in Inocybe Mushrooms

Jiri Patocka et al.

Summary: Mushroom poisoning is a serious threat to human health, attracting attention of researchers to study the toxin composition and toxic effects. Inocybe mushrooms contain various toxic substances such as muscarine, psilocybin, and psilocin. Understanding the toxic effects and mechanisms of these substances, as well as their potential medical applications, is crucial for preventing and treating mushroom poisoning.

Three new species of Inosperma (Agaricales, Inocybaceae) from Tropical Africa

Hyppolite L. Aignon et al.

Summary: Three new species of Inosperma from Tropical Africa were described, with morphological and molecular data confirming their novelty. Phylogenetic placements of these species were inferred based on molecular evidence, alongside interspecific variation analysis using ITS dataset. Complete descriptions, illustrations, and a new combination proposal were provided for each species.

Fungal Biodiversity Profiles 101-110

Bart Buyck et al.

Summary: In this new series of Fungal Biodiversity Profiles, the authors describe a new species of Rachomyces Thaxt. and several Basidiomycota, as well as illustrated type studies for older species of Cantharellus Adans. ex Fr. and newly described species of Inosperma and Rhodophana. The study also provides sequence data and phylogenetic analyses to support the new species in Basidiomycota.

Two new Inosperma (Inocybaceae) species with unexpected muscarine contents from tropical China

Lun-Sha Deng et al.

Summary: Accurate identification and confirmation of toxins in poisonous mushrooms are crucial in treating mushroom poisoning incidents. This study proposed two new Inosperma species, I. muscarium and I. hainanense, from tropical Asia, with high levels of muscarine detected in both species.
