Notes: Amanita has been divided into two monophyletic units, Amanita (ectomycorrhizal) and Aspidella (saprotrophic) (Gilbert 1940; Bas 1969; Vizzini et al. 2012; Wolfe et al. 2012). Saproamanita was introduced by Redhead et al. (2016) to replace Aspidella and typified by S. vittadinii (syn. A. vittadinii). Based on the morphology, Saproamanita was placed in Amanitaceae (Agaricales, Agaricomycetes). Saproamanita is most similar to that of the Amanita subgenus Lepidella, characterized by volval elements dominated by cylindrical to slender clavate inflated cells together with elongated stipes in which these elements are mostly scattered mid-stipe. The species in this genus can grow in open fields and grass land steppes (Beauseigneur 1926; Bas 1969). The multi-locus phylogenetic studies also support the contention that Saproamanita should be placed in Amanita subgen. Lepidella (Davison et al. 2013; Cui et al. 2018; Yang et al. 2018c). Currently, 24 taxa of Saproamanita are listed in the species Fungorum (2021). However, only two species, S. praegraveolens and S. thiersii have been reported in Thailand (Chandrasrikul et al. 2011). 

Other accepted species: Species Fungorum – search Saproamanita.
