Galanthus (convolute). He merged "Nivalis" and "Plicati" into series "Galanthus", and divided "Latifolii" into two subseries, "Glaucaefolii" and "Viridifolii" . Early molecular phylogenetic studies confirmed the genus was monophyletic and suggested four clades, which were labelled as series, and showed that Davis' subseries were not monophyletic. An expanded study in 2013 demonstrated seven major clades corresponding to biogeographical distribution. This study used nuclear encoded nrITS (Nuclear ribosomal internal transcribed spacer), and plastid encoded "matK" (Maturase K), "trnL-F", "ndhF", and "psbK–psbI", and examined all species recognised at the time, and also two naturally occurring putative hybrids. The morphological characteristic of vernation that
Amanita nivalis Amanita nivalis Amanita nivalis, the snow ringless amanita or mountain grisette, is a species of basidomycote fungus in the genus "Amanita". It was first described by the Scottish mycologist Robert Kaye Greville in 1826 from specimens found growing at high altitudes in the Scottish Highlands. He gave it the Latin epithet "nivalis" (of the snow) to indicate the alpine type habitat in which he found it growing rather than to describe its white colour. "Amanita nivalis" is a small species of fungus which is usually white when young but which becomes tinged with grey or buff as it ages. It
