Plain language summary
Saproamanita is a newly recognized mushroom genus that can inhabit lawns or fields and sometimes forms fairy rings. The type species is Saproamanita vittadinii. To assist in modern DNA based phylogenetic analyses of mushrooms including S. vittadinii, a molecularly characterized epitype was selected to link to the type illustration published in 1826. No original specimen exists and therefore DNA sequences cannot be obtained from an original specimen.
Abstract
Agaricus vittadinii Moretti (1826a: 66) is a striking species traditionally ascribed to the genus Amanita Pers. (1797: 65) (Bas 1969; Traverso 1998; Neville & Poumarat 2004). Amanita is one of the most widespread, species-rich ectomycorrhizal genera (Yang 1997; Yang et al. 1999; Neville & Poumarat 2004; Tulloss 2000; Kirk et al. 2008; Tulloss & Yang 2015), characterized by usually agaricoid basidiomata (including sequestrate forms) with a pallid spore print, a hemiangiocarpic schizohymenial development, presence of both universal and partial veils, and usually white and free lamellae (Bas 1969; Neville & Poumarat 2004; Justo et al. 2010). Microscopically, diagnostic characters are amyloid or inamyloid spores, bilateral hymenophoral trama and longitudinally acrophysalidic stipe tissue, which consists of clavate, usually terminal elements, longitudinally oriented on a diffuse system of narrow, branching hyphae (Corner & Bas 1962; Bas 1969; Jenkins 1986; Yang 1997, 2005; Traverso 1998; Neville & Poumarat 2004).
