AGARICACEAE, Fries.
Reading edition
Hymenium covering the entire surface of radiating lamellae or gills. Spores one-celled.
Primary divisions of the Agaricaceae depend on the colour of the spores as seen in the mass, when deposited on an opaque substance; and not as seen under the microscope by transmitted light.
I. Leucosporae. Spores white. In some cases with a tinge of yellow or pink. In some species of Russula the spores are clear ochre, but such species belong obviously to Russula notwithstanding.
II. Chlorosporae. Spores clear green or bluish-green.
III. Rhodosporae. Spores salmon-colour or pink.
IV. Ochrosporae. Spores ochraceous or rust-colour.
V. Melanosporae. Spores black, blackish-brown, or black with a purple tinge.
