Figure 126.—Pleurotus abscondens. Entire plant white.
Abscondens means keeping out of view. It is so called because it persists in growing in places where it is hidden from sight.
The pileus is often two and a half inches broad, delicate-white, strong stringent odor, usually pruinose, margin slightly incurved.
The gills are attached to the stem, rather crowded, very white, somewhat narrow.
The stem is short, solid, pruinose, usually lateral, and curved.
The plant usually grows in hollow stumps or logs, and in this case the stem is always lateral and the plant grows very much as does the P. ostreatus, except that they are not imbricated. Occasionally the plant is found on the bottom of a hollow log and in that case the cap is central and considerably depressed in the center. I have never seen it growing except in a hollow stump or log. Its manner of growth and its delicate shape of white will serve to identify it. It is found from August to November.
Pleurotus circinatus. Fr.
Circinatus means to make round, referring to the shape of the pileus.
The pileus is two to three inches broad, white, plane, orbicular, convex at first, even, covered over with silky-pruinose lustre.
The gills are adnate-decurrent, rather crowded, quite broad, white.
