GLOSSARY OF THE MORE TECHNICAL TERMS USED IN THIS WORK.

Abbreviations:

cm. = centimeter (about 2-1/2 cm. make one inch).
mm. = millimeter (about 25 mm. make 1 inch).
mu = one micron (1000 mu = 1 mm.).

Adnate, said of the gills when they are attached squarely, or broadly,
to the stem.

Adnexed, said of gills when they are attached only slightly or only by
the upper angle of the stem.

Anastomose, running together in a net-like manner.

Annulus, the ring or collar around the stem formed from the inner or
partial veil.

Appendiculate, said of the veil when it clings in fragments to the
margin of the pileus.

Arachnoid, said of the veil when it is cobwebby, that is, formed of
loose threads.

Ascus, the club-shaped body which bears the spores inside
(characteristic of the Ascomycetes).

Basidium (pl. basidia) the club-shaped body which bears the spores in
the Basidiomycetes. These stand parallel, and together make up the
entire or large part of the hymenium or fruiting surface which
covers the gills, etc. Paraphyses (sterile cells) and sometimes
cystidia (longer sterile cells) or spines are intermingled
