Glossary
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
