“…The current classification of the genus Amanita is based on combined data on their morphological characteristics and molecular data. Moreover, multi-gene molecular phylogeny has provided researchers with a powerful tool for the identification of the Amanita species [ 4 , 14 , 36 , 52 , 53 , 54 , 58 ]. In this present study, specimens of the edible Amanita species collected in northern Thailand were identified as A. hemibapha, A. pseudoprinceps, A. rubromarginata, and A. subhemibapha based on morphological characteristics and multi-gene phylogenetic analyses.…”

Edible wild mushrooms are extremely popular among consumers and are highly valued for their potential economic benefits in northern Thailand. In this present study, a total of 19 specimens of edible Amanita were collected during investigations of wild edible mushrooms in northern Thailand during the period from 2019 to 2022. Their morphological characteristics and the phylogenetic analyses of the internal transcribed spacer (ITS) and partial large subunit (nrLSU) of ribosomal RNA, RNA polymerase II second-largest subunit (rpb2) and partial translation elongation factor 1-alpha (tef-1) indicated that the collected specimens belonged to A. hemibapha, A. pseudoprinceps, A. rubromarginata, A. subhemibapha, and Amanita section Caesareae. This is the first report of A. pseudoprinceps and A. subhemibapha from Thailand. Full descriptions, illustrations and a phylogenetic placement of all specimens collected in this study are provided. Subsequently, the nutritional composition and total phenolic content, as well as the antioxidant and α-glucosidase inhibitory activities, of each species were investigated. The results indicate that the protein contents in both A. pseudoprinceps and A. subhemibapha were significantly higher than in A. hemibapha and A. rubromarginata. The highest total phenolic content was found in the extract of A. pseudoprinceps. In terms of antioxidant properties, the extract of A. pseudoprinceps also exhibited significantly high antioxidant activity by 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays. However, the extract of A. rubromarginata had the lowest total phenolic content and level of antioxidant activity. Additionally, α-glucosidase inhibitory activity varied for different Amanita species and the highest level of α-glucosidase inhibitory activity was found in the extract of A. pseudoprinceps. This study provides valuable information on the nutrient content, phenolic content and the antioxidant and α-glucosidase inhibitory potential of edible Amanita species found in northern Thailand.

“…They are ecologically relevant because the majority of them form ectomycorrhizal associations with vascular plants and play important roles in ecosystems and forest development (Yang, 1997). Taxonomic studies of Amanita from Asia have largely focused on China, India, and Japan (Nagasawa and Hongo, 1984;Yang, 1997;Oda et al, 1999;Moncalvo et al, 2000;Tulloss et al, 2001;Chen et al, 2001;Yang, 2001Yang, , 2002Oda et al, 2002;Yang, 2004;Jie et al, 2009;Zhang et al, 2010;Chen, 2014;Deng et al, 2014;Zhang et al, 2015;Yang, 2015;Endo et al, 2017;Cui et al, 2018;Yang et al, 2018). About 60 species of Amanita have been reported from various parts of India, and more than 160 species have been reported from China (Yang, 1997(Yang, , 2000Semwal et al, 2014;Singh and Kaur, 2016;Cui et al, 2018;Yang et al, 2018).…”

Two new species found in Northwestern Pakistan in the mushroom genus Amanita are described and illustrated. Phylogenetic data derived from nuclear ribosomal ITS and LSU regions along with morphological characterizations indicate that these species are novel. Amanita cinis is a member of section Roanokenses, while A. olivovaginata is representative of the section Vaginatae. Amanita emodotrygon, recently described from the state of Uttarakhand, India, is new to Pakistan.

Amanita caesareoides Lj.N. Vassiljeva, belonging to the section Caesareae, is associated with Pinaceae and Fagaceae trees as an ectomycorrhizal symbiont (Endo, 2015;Endo et al., 2013). Several species in the sect. Caesareae ("Caesar's mushrooms") are edible mushrooms and are consumed globally. The sect. Caesareae is estimated to have originated around 60 Mya (Paleocene) in the Africa, and then expanded to Europe, Australia, and North and Central America through southwest of Laurasia (present southeast Asia) (Sánchez-Ramírez et al., 2015a). In Japan and the surrounding Far East Asian region, the reddish-pileus Caesar's mushrooms, repre-sented by A. caesareoides, are estimated to have expanded from the ancestral clade around 8-6 Mya (late Miocene; Tortonian-Messinian) (Sánchez-Ramírez et al., 2015a).Amanita caesareoides was first described from the Kamchatka Peninsula, Russia (Vassiljeva, 1950) but treated as A. caesarea (Scop.
