“…Section Amanita is distinguished by basidioma with agarose; a pileus with persistent volval remnants, a pileal margin striate; truncated lamellae; presence of a basal bulb; and inamyloid basidiospores (Cui et al, 2018). Many species in this section produced neuropsychotoxins (Wieland, 1973;Yang, 2005;Chen et al, 2016). Studies have identified 27 taxa, comprising 23 species, 2 varieties, and 2 forms, in China (Cui et al, 2018;Su et al, 2022).…”

Globally, the species of Amanita are key components of ectomycorrhizal ecosystems. Some of them are widely known as poisonous or edible fungi. Although many new Amanita species from China have been described, the species diversity of Yanshan Mountains remains unknown. We here describe three new species, namely, A. borealis sp. nov. (Sect. Amanita), A. brunneola sp. nov. (Sect. Caesareae), and A. yanshanensis sp. nov. (Sect. Validae), based on morphological observations and molecular phylogenetic analyses. In addition, nine known species, namely, A. caesareoides (Sect. Caesareae), A. chiui (Sect. Vaginatae), A. muscaria (Sect. Amanita), A. oberwinklerana (Sect. Roanokenses), A. ovalispora (Sect. Vaginatae), A. subglobosa (Sect. Amanita), A. subjunquillea (Sect. phalloideae), A. vaginata var. vaginata (Sect. Vaginatae), and A. virosa (Sect. phalloideae), were reported from Yanshan Mountains for the first time. Our results emphasize that China has a high diversity of Amanita species and that additional studies are required to understand the exact species number. These findings play a crucial role in Amanita toxin research and ecological conservation. This study investigated the areas where Amanita species-related research is lacking. The study also attempted to better understand Amanita distribution and thus contribute to related research. This study enriches the species diversity of Amanita in Yanshan Mountains and offers additional data supporting the macrofungal systematics, toxin research, and diversity and ecological studies of Amanita in future studies.

Eingegangen am 16. Mai 1966y-Amanitin wird nach mehrstufiger chromatographischer Anreicherung, zuletzt zur Abtrennung farbiger Verunreinigungen an Sephadex G-25, kristallin erhalten. Das Gift (LD5o = 0.2 mg/kg weil3e Maus, langsam wirkend) zeigt in seiner Zusammensetzung groRe Ahnlichkeit mit a-Amanitin bis auf eine y-Hydroxyaminosaure, der -wie sich spater herausstellte, irrtumlich -die Struktur P-Methyl-y-hydroxy-Ieucin zugeschrieben wurde.
