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 in the Rocky Mountains in North America. The fruit bodies appear singly or in small groups in both silicaceous and limestone areas in summer. The edibility of this species is not known but because of its rarity, it is best not to gather it. 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
