چکیده

Two ectomycorrhizal macrofungal Amanita species of the section Lepidella, A. strobiliformis and A. solitaria, were found to hyperaccumulate silver (Ag). All samples were collected from non-argentiferous areas with background Ag content in soils (0.07-1.01 mgkg(-1) Ag). The Ag contents of both Amanita species were mostly in the range of 200-700 mgkg(-1)D.W. with the highest Ag content of 1253 mgkg(-1) in one sample of A. strobiliformis. Silver concentrations in macrofungal fruit bodies were commonly 800-2500 times higher than in underlying soils. A. strobiliformis and A. solitaria are the first eukaryotic organisms known to hyperaccumulate Ag.

Molecular phylogeny of eastern Asian species of Amanita (Agaricales, Basidiomycota): taxonomic and biogeographic implications

The phylogenetic relationships, taxonomy and biogeography of the genus Amanita with emphasis on eastern Asian species were estimated using sequence data from both internal transcribed spacer (ITS) regions and large subunit (nLSU) of nuclear ribosomal DNA. The separation of the two traditionally accepted subgenera was not well supported. Each section of Amanita, Vaginatae, Caesareae, Phalloideae...

Study of three interesting Amanita species from Thailand: Morphology, multiple-gene phylogeny and toxin analysis

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. brunneitoxica...

Taxonomic Study of Amanita Subgenus Lepidella and Three Unrecorded Amanita Species in Korea

Amanita Pers. is a well-known monophyletic mushroom genus with a broad distribution. However, the diversity of Korean Amanita species has been underestimated, and most taxonomic studies conducted in Korea have only investigated their morphological characteristics. This approach is frequently insufficient for correct identification in fungal classification; therefore, we constructed a phylogeny ...

Saproamanita, a new name for both Lepidella E.-J. Gilbert and Aspidella E.-J. Gilbert (Amaniteae, Amanitaceae)

The genus Amanita has been divided into two monophyletic taxa, Amanita, an ectomycorrhizal genus, and Aspidella, a saprotrophic genus. The controversies and histories about recognition of the two genera based on trophic status are discussed. The name Aspidella E.-J. Gilbert is shown to be illegitimate and a later homonym of Aspidella E. Billings, a well-known generic name for an enigmatic fossi...
