=Marasmius=. Tough, drying up and reviving when moistened; gills often connected by veins.

+++ Gills decurrent.

=Lactarius=. Gills and flesh exuding milk when broken. (In some sp. the gills are adnate.)

=Hygrophorus=. Gills thick at the base, edge acute, rather waxy, often branched; pileus often hygrophanous. (In some sp. the gills are adnate or even free.)

=Clitocybe=. Gills thin, pliant, sometimes powdered with the spores; stem fibrous outside.

=Omphalia=. Gills thin, pliant, stem cartilaginous outside.

=Pleurotus=. Growing on wood. Stem lateral or excentric when present.

=Cantharellus=. Gills narrow, edge thick, rather waxy, forking.

=Arrhenia=. Gills reduced to very slight wrinkles or veins.

=Nyctalis=. Gills thick, edge blunt. Parasitic on fungi, or among dead leaves, &c.

** TENACES. Coriaceous, corky, or woody, persistent, rigid when dry.

=Lentinus=. Pileus coriaceous; gills decurrent, edge toothed or eroded.

=Panus=. Pileus coriaceous; gills decurrent, edge quite entire.

=Xerotus=. Pileus coriaceous; gills forking, edge thick.

=Lenzites=. Horizontal, sessile, woody or corky; gills radiating from behind.

II. SCHIZOPHYLLAE. Margin of gills split open.

=Trogia=. Gills resembling folds or wrinkles, edge grooved. (In the only European species the edge of gills not grooved.)

=Schizophyllum=. Margin of gills split, the split portions rolling outwards.

ABBREVIATIONS USED.

Cm. = centimetres; compr. = compressed; decur. = decurrent; depr. = depressed; exp. = expanded; g. = gills; hygr. = hygrophanous; infundib. = infundibuliform; mm. = millimetres; p. = pileus; s. = stem; sp. = spores; umb. = umbonate; umbil. = umbilicate.

The measurement given of the stem is that of its average length; that of the pileus, its average breadth when expanded. The measurement of the spores is given in micro-millimetres, usually indicated by the Greek letter mu.
