TERM DESCRIPTION
abruptly adnexed see adnexed
acanthophysis see hyphidium
aciculate very slender, with sharp top, therefore needle-shaped
acidulous slightly acid
acrid taste burning or peppery, in this program the description of 'acrid' is rendered as 'peppery'
acula (plural aculae) spine
aculeate of cystidia, tapered so that only the very basal portion is relatively swollen, the entire cystidium being shaped like a spine, therefore spine-shaped; of spore, means having narrow spines
acuminate gradually narrowed to a point
acute pointed, sharp; less than a right angle
acyanophilous not cyanophilous
adnate refers to gills that are broadly attached to the stem, the lower edge of the gill being attached at the line at which a straight gill edge would intersect the stem: if attached above this line it would be adnexed or notched, if attached below this line it would be decurrent; if ascending adnate gills attach at much less than a right angle, appearing to curve upward toward stem; if adnate horizontal, gills attach at about a right angle; if broadly adnate, attached to the stem along their entire height
adnexed refers to gills that are narrowly attached to the stem: the gill edge curves gradually upward along the inner half of the gill and is attached to the stem by a narrow upper portion of the gill; if abruptly adnexed, gill edge curves abruptly upwards to stem but makes contact with stem in straight line (does not curve as in sinuate attachment)
aeriferous appearing as if air is trapped
aeruginose verdigris-green, (malachite-green), the color of oxidized copper
agaric mushroom with gills
agaricologist a person who studies gilled mushrooms
agaricology the study of gilled mushrooms
agglutinated surface fibrils or scales drawn together in clumps
allantoid sausage-shaped, tubular and slightly curved with rounded ends
alliaceous smelling or tasting like onions or garlic
almond-shaped of spores, with top end broader than base (where hilar appendage located), thus like an almond in shape
alternate names other names for the same species, given in the description immediately following the primary name; these are earlier or later or illegitimate name for the species, representing all or part of the concept of the primary name: the primary name includes the alternate name, but the alternate name may not include the whole concept represented by the primary name
alutaceous light leather colored, usually interpreted as light tan or medium yellow brown
alveolate surface of cap or spore with broad pits
amanitin same as amatoxin
amanitoid like Amanita, with free or slightly adnexed gills, a volva, and a ring
amatoxin cyclic peptide found in Amanita and other genera that are very toxic
amorphous shapeless, formless
ampullaceous flask-shaped
ampulliform flask-shaped; of cystidia, with base and middle parts wide and top part like a beak but wider than in ventricose-rostrate cystidia
amygdaliform almond-shaped
amygdaline (odor or taste) like peach or cherry stones
amygdaloid almond-shaped
amyloid staining bluish to gray to black in Melzer's reagent
anamorph the asexual reproductive manifestation of a fungus, characterized by asexual spores
anastomosing forming a network, connecting by cross-veins
angular 4 to 7 sided, with corners or angles
angular-nodulose of angular spores, having small lumps protruding at the angles
angular-tuberculate of angular spores, having bumps at the angles that are less obvious than those in angular-nodulose spores
anise of an odor, like that of star anise or anise seed, often considered to be like licorice
annular resembling a ring or referring to a ring, as in an annular zone on stem
annular zone a band of fibrils or gluten around stem, often becoming darkened by spores, normally derived from veil remnants, but too obscure to be a ring
annulate bearing an annulus
annulus ring or collar of tissue on stem formed by ruptured of the veil that initially joins the stem to the cap edge
anthesis point of development of fruiting body at which the fresh unexpanded cap is in "full flower", contains the features for identification, and is at the brink of spore release
apex top, highest part
apical near top
apical pore same as germ pore, not to be confused with apiculus, which is the other end of the spore
apiculate with an apiculus
apiculus nipple-like projection; nipple-like projection on spore which corresponds to the area that was attached to the basidium, sometimes used to refer to a projection on the other end of the spore, same as hilar appendage and not to be confused with apical pore (germ pore)
appendiculate margin of cap fringed with hanging fragments of the veil; (of cystidium) having an appendage; (of a spore) having one or more setulae
applanate horizontally expanded, plane, flat
appressed flattened down
appressed-fibrillose fibrils are pressed down flat against surface
apud indicates a name published by one author in the work of another
arachnoid cobweb-like
arching of gills, the same as arcuate
arcuate forming an arch; of gills, means that the middle of the lower edge of the gill is higher than its ends
areolate surface cracked into plaques or blocks, like the cracking that occurs when mud dries in the sun
argillaceous clay color, resembling ochraceous-cinnamon-brown
armillarioid with attached gills, fleshy stem and ring
army brown vinaceous brown
ascending refers to gills that curve upwards from the margin of the cap to the attachment at the stem, as in conic or unexpanded cap
ascomycete fungus belonging to Ascomycota
Ascomycota Phylum that includes the largest group of fungi, those that produces their spores in sacs called asci, but does not include any gilled mushrooms
asperulate of spores, appearing roughened with tiny points; or roughened with small warts
asterostromelloid type of pellis found in Resupinatus composed of swollen terminal elements with short approximately perpendicular branches
astringent causing a contraction or pucker of the mouth membranes
atomate a powdered surface consisting of minute shiny particles
attenuate gradually narrowed
authority name, often abbreviated, of the mycologist(s) responsible for the taxonomy and nomenclature of a taxon, cited after the Latin name of the genus, species, variety etc.
autodigestion self-digestion
avellaneous dull grayish brown, hazel-brown, or light gray-yellow-brown, or closer to drab, or gray tinged with pink, in Ridgway 1912 a color closer to pinkish buff
azonate without zones, without concentric markings
azure sky-blue
