+OMPHALIA = depressed.+

The stem in this genus is cartilaginous. The gills run down the stem.
The cap is somewhat membranaceous. It is oftener depressed and
funnel-shaped. The gills are often branched. The species grow in moist
places. The plants are generally small. The largest only measure 2
inches, the smallest only ½ inch across the cap.

+PLEUROTUS = side and an ear.+

In this genus the stem is sometimes wanting, or it grows on the side, or
between the centre and margin (eccentric). The plants rarely grow on the
ground. They are irregular and fleshy or membranaceous. The time of
growth is generally in the autumn. There are a few edible species.

SECTION 2. RHODOSPORÆ, RED OR PINK SPORES.

In this section of Agarics the spores are red, pink, or salmon color.

+PLUTEUS = a penthouse.+

This genus has neither volva nor ring. The gills are rounded behind and
free, entirely separate from stem, white, then flesh-colored, but often
tinged with yellow. The cuticle is sometimes covered with fibres, or
with a bloom upon it (pruinose). The apex of the stem is inserted in the
cap like a peg, and in this it resembles the Lepiotas. The species grow
on or near trunks, appear early, and last until late in the season.

+ENTOLOMA = within and fringe.+
