Titlesort icon Body
acervulus A mat of hyphae bearing short conidiophores packed closely together
acicular having the form of a needle.
acuminate tapering to a sharp point
Adnate (of gill profile) attached to stem by the full depth of the gill
Adnexed (of gill profile) attached to stem by a narrower amount than the full depth of the gill
Adpressed Closely flattened against/onto a surface
aeciospore dikaryotic spore of a rust fungus produced in an aecium; in heteroecious rusts, a spore stage that infects the alternate host
aecium (pl. aecia adj. aecial) the fruiting body of a rust fungus in which the first dikaryotic spores (aeciospores) are produced
aethalium (pl. aethalia)

a large, plump, pillow-shaped fruiting body of certain myxomycetes, formed by the aggregation of plasmodia into a single functional mass.

Agaric(ales) Generic term for gill-bearing fungi
Allantoid (of spores) curved as in sausage shape
Alliaceous

Smelling or tasting of garlic or onions.

alveolae small hollows in a surface.
Amorphous Lacking clear structure
Amyloid Turning blue/blue-black in iodine solution such as melzer's reagent
Anastomosing

Fused together in a vein-like network; used to describe mushroom gills that are interconnected with veins
 

Annulus Ring around stem, remnant of partial veil covering young emergent sporophore*

Apex

The top, highest part.

Apical Towards the apex
Apiculus (of spores) a short projection at the base
aplanospore A non-motile spore
apothecium (pl. apothecia) open, cuplike or saucerlike, ascus-bearing fungal fruiting body (ascocarp), often supported on a stalk
Appendiculate Fringed with remains of the veil
Applanate Flattened
Arbuscules Miniscule, tree-like hyphal branching structures produced within host plant cells by arbuscular mycorrhizal fungi
Arcuate (of gill profile) with concave edge in side view
Arthrospore Asexual spore formed by the septation and fragmentation of a hypha
ascomata structures bearing or containing asci
Ascomycetes Major group containing all fungi producing spores in asci which are liberated by pressure
Ascospore Reproductive cell (spore) of the acsomycete fungi
Ascus(pl. Asci) Microscopic elongated flask-shaped cell in which ascospores are produced
Attenuate

Gradually narrowed

Azonate

Without zones or concentric markings
