Key to major groups based on character of basidium and fruit-body shape
Оглавление1. Basidia either produced in a hymenium or in a mass, and until maturity contained within a closed fruit-body Gasteromycetes
Basidia produced in a layer of cells (hymenium) and exposed to the air before the maturity of the spores (Hymenomycetes) 2
2. Basidia simple, a single cell (fig. 5) (Homobasidiae) 3
Basidia usually septate, or if simple then fruit-body gelatinous and often collapsing to form a skin when dried (Heterobasidiae) 4
3. Fruit-body usually fleshy, soft and easily decaying (putrescent), hymenium spread over the surface of gills, ridges or within tubes Agaricales (p. 22)
Fruit-body with hymenium smooth or spread-out on teeth, ridges or plates or if within tubes then fruit-body tough and leathery Aphyllophorales (p. 135)
4. Basidia divided 5
Basidia simple and apex drawn out into two long necks Plate 61 (p. 185) Dacrymycetales (p. 180)
5. Basidia divided transversely by one to three horizontal septae Plate 60 (p. 183) Auriculariales (p. 182)
Basidia divided into two or four cells by vertical septae Plate 61 (p. 185) Tremellales (p. 184)
