_Divergent_ (of the gill-trama in transverse longitudinal section), with the hyphae curving downwards and outwards on both sides of a central zone as if combed. See Fig. 9A, p. 17. _Ellipsoid_ (of the spores), elliptic in outline in all planes. _Emarginate_ (of the gills), notched near the stem. See Sinuate, p. 263. _Excentric_ (of the cap), laterally placed on the stem. _Expallent_ (of the cap), becoming paler when drying. _Expanded_ (of the cap), opened out when mature. See Plate 10, p. 61. _Fibrillose_ (of the cap and stem-surfaces), almost smooth but for distinct parallel longitudinal filaments (fibrils). _Fleshy_ (of the fruit-body), of a rather soft consistency: readily decaying. _Floccose_, with loose, cottony surface; diminutive--flocculose. _Free_ (of the gills and tubes), not attached to the stem. See p. 267. _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.
