Amanita ballerina and A. brunneitoxicaria spp. nov. are introduced from Thailand. Amanita fuligineoides is also reported for the first time from Thailand, increasing the known distribution of this taxon. Together, those findings support our view that many taxa are yet to be discovered in the region. While both morphological characters and a multiple-gene phylogeny clearly place A. brunneitoxicaria and A. fuligineoides in sect. Phalloideae (Fr.) Quél., the placement of A. ballerina is problematic. On the one hand, the morphology of A. ballerina shows clear affinities with stirps Limbatula of sect. Lepidella. On the other hand, in a multiple-gene phylogeny including taxa of all sections in subg. Lepidella, A. ballerina and two other species, including A. zangii, form a well-supported clade sister to the Phalloideae sensu Bas 1969, which include the lethal “death caps” and “destroying angels”. Together, the A. ballerina-A. zangii clade and the Phalloideae sensu Bas 1969 also form a well-supported clade. We therefore screened for two of the most notorious toxins by HPLC-MS analysis of methanolic extracts from the basidiomata. Interestingly, neither α-amanitin nor phalloidin was found in A. ballerina, whereas Amanita fuligineoides was confirmed to contain both α-amanitin and phalloidin, and A. brunneitoxicaria contained only α-amanitin. Together with unique morphological characteristics, the position in the phylogeny indicates that A. ballerina is either an important link in the evolution of the deadly Amanita sect. Phalloideae species, or a member of a new section also including A. zangii.

“…Takah. differs from A. caesareoides by distinctive long-sulcate striations on the margin of the pileus, carrot red to deep orange to brownish orange, greyish orange or apricot colours toward the margin (Thongbai et al 2016). Amanita caesareoides also differs from A. javanica (Corner & Bas) T. Oda, C. Tanaka & Tsuda by its yellow to orange-yellow pileus (Oda et al 1999).…”

“…Most species in the genus are associated with different trees and shrubs including members of Betulaceae, Dipterocarpaceae, Fabaceae, Myrtaceae, Pinaceae, and Salicaceae , Thongbai et al 2016, Tibpromma et al 2017. It comprises of 540 described and validly published species all over the world and about 50 species are reported from India (Bhatt et al 2003, Thongbai et al 2016, Das et al 2017, Tibpromma et al 2017. Amanita is concisely characterized by bilateral lamellar trama, longitudinally acrophysalidic stipe context, schizohymenial development in their agaric and secotioid species , Tibpromma et al 2017).…”

Macrofungi belong to genus Amanita was collected during a fungal foray in temperate to subalpine forests in Uttarakhand Himalaya in monsoon period of 2014−2016. Through critical macro-and microscopical examination of these samples, six species were identified as new records to India. Amanita caesaroides (sect. Caesareae), Amanita griseofolia (sect. Vaginatae), Amanita orientifulva (sect. Vaginatae), Amanita pallidorosea (sect. Phalloideae), Amanita parvipantherina (sect. Amanita) and Amanita princeps (sect. Caesareae) are described here with detailed descriptions and illustrations. All these species were found in mycorrhizal association with different host trees, conifers as well as angiosperms. Apart from this, Amanita princeps is found as an edible species in various countries, in addition to this species, Amanita caesaroides was also reported to be consumed in temperate to subalpine regions of Uttarakhand Himalaya during this study.

Burkina Faso has abundant wild mushrooms, but very few inventories have been carried out to record these species. The shortage of taxonomic studies in Burkina Faso on wild mushroom species limits their knowledge. Three species of the genus Amanita from Burkina Faso are reported and fully described in this paper. They are Amanita pulverulenta Beeli, Amanita citrina (Schaeffer) Persoon and Amanita odorata Beeli. All the three species were collected in the classified forest of Niangoloko, preciously in the mosaic gallery forests dominated by Berlinia grandiflora (Vahl) Hutch. & Dalziel and Isoberlinia doka Craib & Stapf (Caesalpiniaceae) and are assumed to be ectomycorrhizal.
