Adnate

Gills broadly attached to the stem.

Adnexed

Gills rounded towards the stem, narrowly adnate.

Amyloid

A tissue or feature is said to be amyloid if it has a positive so-called amyloid reaction when subjected to a crude chemical test using iodine in Melzer's reagent, producing a blue to blue-black staining. A reaction producing a deep reddish to reddish brown staining is termed either a pseudoamyloid reaction or a dextrinoid reaction.

Arcuate

Gills with concave edge in side view.

Basidium

(pl. basidia) A microscopic, club-shaped, spore-producing structure found on the lamellae of the fungus

Cartilaginous

Firm and tough, yet flexible.

Caulocystidium

(pl. caulocystidia) A relatively large cell found on the stipe surface

Cespitose

Growing in tufts or clumps

Cheilocystidium

(pl. cheilocystidia) A relatively large cell found on the gill edge. In the genus Mycena, the cheilocystidia are highly variable and often most useful for species delimitation

Clamp

A clamp connection is a connection between two fungal cells. Rather than merely terminating with a simple dividing wall, clamped cells involve a little arm, or clamp, that reaches from one cell to the next, appearing to hold the cells together. It is created to ensure each cell, or segment of hypha separated by septa, receives a set of differing nuclei, which are obtained through mating of hyphae of differing sexual types. In Mycena the presence or absence of clamps has been used in identification of species.

Clavate

Club-shaped

Decurrent

Gills continuing down the stem.

Decurrent tooth

A tooth-like prolongation of the gills down the stem.

Dextrinoid

See amyloid.

Diverticulate

With short finger-like excrescences.

Ellipsoid

With the outline of an ellipse.

Farinaceous

(smell) reminding of fleshly ground meal

Fasciculate

Growing in a bundle

Fibrillose

Covered with thin fibres.

Floccose

Loose cottony or downy woolly.

Flocculose

Minutely floccose.

Fusiform

Spindle-shaped, tapering at both ends.

Glabrous

Bald, naked.

Gregarious

Growing in colonies or crowds

Hyaline

Transparent, translucent, colourless.

Hygrophanous

Changing colour markedly on drying.

Hymenium

The spore-producing layer under the cap.

Hypha

(pl. hyphae) A long, filamentous structure of the fungus. In Mycena the hyphae are divided into cells by internal cross-walls called "septa".

Insititious

Arising cleanly from the substrate, with no fibrils attached.

Ixocutis

A cutis made up of gelatinous hyphae.

Lageniform

Bottle shaped.

Lamellae

Gills. Thin and plate-like structures growing out from the underside of the cap and covered with hymenium

Lubricous

slippery.

Melzer's reagent

A solution of iodine and iodide of potassium in chloral hydrate, used for testing of amyloidity and dextrinoidity

Papilla

A minute umbo

Pellicle

A thin skin, organic membran.

Pleurocystidium

(pl. pleurocystidia) A relatively large cell found on the gill edge

Pileocystidium

(pl. pileocystidia) A relatively large cell found on the surface of the cap

Pileipellis

The uppermost layer of hyphae in the cap.

Pip-shaped

Shaped like a small apple seed.

Pruinose

Covered with a fine powder

Pyriform

Pear-shaped

Rugose

Coarsely wrinkled

Rugulose

Finely wrinkled

Stipitipellis

The hyphae of the cortical layer of the stem.

Sulcate

With grooves

Tortuous

full of twists, turns, or bends.

Utriform

(Form of a cystidia) With the neck more than half as broad as the body

Umbo

A knoblike protuberance arising from the center of the cap

Umbonate

Provided with an umbo
