Part 85

Frondose trees, broad-leaved trees.

Fruit-body, the whole agaric (toadstool or mushroom, polypore, etc.), as usually understood.

Germ-pore, a differentiated apical, usually thin-walled portion of the spore. See Fig. 5, p. 15.

Gill, the structure on which the reproductive tissue is borne in agarics, resembling plates.

Globose (of the spore), round in outline in all planes.

Glutinous (of the cap or stem), provided with a sticky jelly-like coating.

Heteromerous (of the cap and stem-flesh), with discrete nests of rounded cells in a background of filamentous cells: characterises members of the Russulaceae. See Fig. 10B, p. 17.

Homoiomerous (of the cap and stem-flesh), not sharply differentiated into two types of cells, although some may be swollen: characterises agarics other than members of the Russulaceae. See Fig. 10A, p. 17.

Hygrophanous (of the cap), translucent when wet, opaque and often paler on drying.

Hymenium, the superficial layer of cells in which basidia occur. See Fig. 9A-D, p. 17.

Hyaline, appearing as if clear glass.

Hypogeous, growing under ground.

Hypha, a fungus filament composed of a chain of several cells; plural--hyphae; adjective--hyphal.

Inverse, (of the gill-trama in transverse longitudinal section), with the hyphae curving upwards and outwards on both sides of a central zone. See Fig. 9B, p. 17.

Irregular (of the gill-trama in transverse longitudinal section), lacking any clear pattern as to hyphal arrangement. See Fig. 9D, p. 17.

Mealy, covered in powdery granules, resembling meal.

Mycelium, a mass of fungus-filaments (hyphae).

Mycorrhiza, a symbiotic association of a fungus and the roots of a higher plant.

Non-amyloid (of the spore-wall, spore-ornamentation and hyphal walls), remaining uncoloured or becoming yellowish in solutions containing iodine.

OCHRACEOUS, bright clay-colour: colour of ochre (yellow-brown).

OLIVACEOUS BROWN, a dull clay-brown with an additional but distinct hint of dirty green.

Plano-convex (of the cap), regularly rounded although almost flat. See Plate 13, p. 67--adult fruit-body.

Pruinose (of the cap and stem-surfaces), finely powdered.

Pubescent (of the cap and stem-surfaces), with short, soft hairs.

Putrescent (of the fruit-body), soft and very easily decaying.

Pyriform (of the spore), pear-shaped.

Regular (of the gill-trama in transverse longitudinal section), with hyphae showing no distinct curvature and practically parallel to the gill-surfaces. See Fig. 9C, p. 17.

Remote (of the gills or tubes), separate from the stem by a zone of cap-flesh. See p. 267.
