Arnold _C. tuberosa_ (Fries) Kummer (ii) Glossary of technical terms _Specialised colours are placed in capitals_ _Adnate_ (of the gills or tubes), broadly attached to the stem at least for one quarter of their length. See p. 267. _Adnexed_ (of the gills or tubes), narrowly attached to the stem by less than one quarter of their length. See p. 267. _Amygdaliform_ (of the spore), almond-shaped. _Amyloid_ (of the spore-walls, spore-ornamentation or hyphal walls), greyish or bluish or blackish violet in solutions containing iodine. _Apiculus_ (of the spore), the short peg-like structure at the basal end of the spore by which it is attached to the basidium. See Fig. 5, p. 15. _Arcuate-decurrent_ (of the gills or tubes), curved and extending down the stem. See p. 267. _Ascus_, a clavate to cylindrical or subglobose cell in which the (asco-) spores are borne, usually in eights. _Basidium_, a clavate or subcylindrical cell on which the (basidio-) spores are borne, externally on stalks. See Fig. 5, p. 15. _Cap_ (of the fruit-body), that structure which bears the spore-bearing layers beneath it (= pileus). _Caespitose_ (of the fruit-body), aggregated into tufts. _CINNAMON-BROWN_, the colour of cinnamon powder obtainable from the grocer. _Clavate_ (of the stem, or cystidia), club-shaped. _Convex_ (of the cap), curving outwards. See Plate 9, p. 55. _Cortex_ (of the cap or stem), outer layers of the tissue. _Cortina_, a cobweb-like veil at first connecting the margin of the cap and stem, but at maturity often only present as remnants on the stem and/or cap-margin. See p. 267. _Cystidium_, a differentiated terminal cell usually on the surface and edges of the cap, gill and stem: facial cystidia occurring on the gill-face: marginal cystidia occurring on the gill-margin. See Fig. 4, p. 15. _DATE-BROWN_, the colour of packed dates. _Decurrent_ (of the gills and tubes), with a part attached to and descending down the stem. See p. 267. _Deliquescent_ (of the gills, cap or entire fruit-body), changing into a liquid at maturity. _Depauperate_ poorly developed. _Depressed_ (of the cap), having the central portion sunken, and (of the tubes) sunken about the apex of the stem. See Plate 1, p. 29. _Dentate_ see toothed. _Distant_ (of the gills), greater than their own thickness apart.
