Glossary

Gills broadly attached to the stem.

Gills rounded towards the stem, narrowly adnate.

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.

Gills with concave edge in side view.

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

Firm and tough, yet flexible.

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

Growing in tufts or clumps

(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

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.

Club-shaped

Gills continuing down the stem.

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

See amyloid.

With short finger-like excrescences.

With the outline of an ellipse.

(smell) reminding of fleshly ground meal

Growing in a bundle

Covered with thin fibres.

Loose cottony or downy woolly.

Minutely floccose.

Spindle-shaped, tapering at both ends.

Bald, naked.

Growing in colonies or crowds

Transparent, translucent, colourless.

Changing colour markedly on drying.

The spore-producing layer under the cap.

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

Arising cleanly from the substrate, with no fibrils attached.

A cutis made up of gelatinous hyphae.

Bottle shaped.

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

slippery.

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

A minute umbo

A thin skin, organic membran.

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

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

The uppermost layer of hyphae in the cap.

Shaped like a small apple seed.

Covered with a fine powder

Pear-shaped

Coarsely wrinkled

Finely wrinkled

The hyphae of the cortical layer of the stem.

With grooves

full of twists, turns, or bends.

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

A knoblike protuberance arising from the center of the cap

Provided with an umbo
