a:- prefix signifying without or absence of.<br />
acrid: a biting or peppery taste.<br />
adnate: (of lamellae) broadly joined to the<br />
stipe; (of cuticle or volva) not peeling<br />
off or pulling off readily.<br />
adnexed: (of lamellae) narrowly joined to<br />
the stipe.<br />
allantoid: sausage-shaped.<br />
alutaceous: light leather-colored, pale tan,<br />
pale brown.<br />
amygdaline: (of taste) like that of peach or<br />
cherry stones.<br />
amyloid: turning blue when treated with a<br />
solution of iodine in chloral hydrate and<br />
water.<br />
anastomose, anastomosing: (of lamellae)<br />
joined crosswise forming angular areas<br />
or a network.<br />
annulus: ring of tissue left on the stipe from<br />
the torn partial veil.<br />
apical: (of stipe) the part near the attachment<br />
of the lamellae or where it joins<br />
the flesh of the pileus, the upper part.<br />
apiculate: provided with an apiculus.<br />
apiculus: (of spores) a short, sometimes<br />
sharp papilla or projection by which the<br />
spore was attached to the sterigma.<br />
apothecium: the usually cup-shaped or<br />
saucer-shaped to saddle-shaped fruiting<br />
body of Discomycetes in which a layer<br />
of asci is exposed to the air.<br />
appendiculate: (of the margin of the pileus)<br />
hung with fragments of the veil or<br />
pellicle.<br />
appressed: closely flattened down.<br />
arcuate: arched or curved like a bow.<br />
areolate: (of the surface of the pileus, or<br />
stipe) marked out in little areas by<br />
cracks or crevices.<br />
ascus (pi. asci): the cell in which the spores<br />
of the Ascomycetes are produced. Typically<br />
there is a fusion of nuclei in the<br />
young ascus followed by three nuclear<br />
divisions resulting in eight ascospores.<br />
atomate: covered with minute shining particles,<br />
glistening like mica.<br />
azonate: not zoned.<br />
basidium (pi. basidia): the cell on which the<br />
spores of the Basidiomycetes are produced.<br />
Typically there is a fusion of<br />
nuclei in the young basidium followed<br />
by two nuclear divisions resulting in<br />
four spores that develop outside the cell<br />
on small stalks.<br />
