Cystidium, a differentiated terminal cell usually on the surface and edges of the cap, gill and stem: facial cystidia occurring on the gill-face: marginal cystidia occurring on the gill-margin. See [Fig. 4], [p. 15].
DATE-BROWN, the colour of packed dates.
Decurrent (of the gills and tubes), with a part attached to and descending down the stem. See [p. 267].
Deliquescent (of the gills, cap or entire fruit-body), changing into a liquid at maturity.
Depauperate poorly developed.
Depressed (of the cap), having the central portion sunken, and (of the tubes) sunken about the apex of the stem. See [Plate 1], [p. 29].
Dentate see [toothed].
Distant (of the gills), greater than their own thickness apart.
Divergent (of the gill-trama in transverse longitudinal section), with the hyphae curving downwards and outwards on both sides of a central zone as if combed. See [Fig. 9A], [p. 17].
Ellipsoid (of the spores), elliptic in outline in all planes.
