PUBLISHER'S NOTE.

It has not been possible to represent all the genera of mushrooms which
contain species having value as esculents within the compass of this
series of five pamphlets, but the demand for these promises to justify
the publication, at a future date, of a second series, which the author
now has in preparation.

AGARICINI.

LEUCOSPORI--(Spores White).

Subgenus _Pleurotus_ Fries. The Pleuroti are similar in some respects to
the Tricholomas and Clitocybes, some of the species having notched gills
near the stem, and others, again, having the gills decurrent, or running
down the stem. Most of the species grow upon dead wood or from decaying
portions of live trees. Very few grow upon the ground. The stem is
mostly eccentric, lateral, or wanting; when present it is homogeneous or
confluent with the substance of the cap; the substance may be compact,
spongy, slightly fleshy, or membranaceous. Veil evanescent or absent.
The spores are white or slightly tinted.

M. C. Cooke figures over thirty species of Pleurotus found in Great
Britain, and describes 45 species found in Australia. With few
exceptions, all of these grow upon wood. Very few have value as
esculents.
