Hymenomycetes

Hymenomycetes, the subdivision of the Basidiomycetes in which the fruiting surface is exposed before the spores are ripe.

Hymenophore

Hymenophore, the portion of the fruit body which bears the hymenium.

Hypha (pl. hyphae)

Hypha (pl. hyphae), a single mycelium thread.

Imbricate

Imbricate, overlapping like the shingles on a roof.

Involute

Involute, folded or rolled inward.

Lamella (pl. lamellae)

Lamella (pl. lamellae), the gills of the mushroom.

Mycelium

Mycelium, the vegetative or growing portion of the mushrooms, and other fungi, made up of several or many threads.

Ocreate

Ocreate, applied to the volva where it fits the lower part of the stem, as a stocking does the leg.

Pectinate

Pectinate, like the teeth of a comb.

Peridium

Peridium, the wall of the puff-balls, etc.

Pileus (pl. pilei)

Pileus (pl. pilei), the cap of the mushroom.

Plicate

Plicate, plaited, or folded like a fan.

Punctate

Punctate, with minute points.

Pulverulent

Pulverulent, with a minute powdery substance.

Repand

Repand, wavy.

Resupinate

Resupinate, spread over the matrix, the fruiting surface external and the pileus next the wood.

Revolute

Revolute, rolled backward.

Rugose

Rugose, wrinkled.

Rugulose

Rugulose, with minute wrinkles.

Saprophytic

Saprophytic, growing on dead organic matter.

Sessile

Sessile, where the pileus is attached directly to the matrix without any stem.

Sinuate

Sinuate, said of the gills when they are notched at their junction with the stem.

Stipe

Stipe, the stem.

Sulcate

Sulcate, furrowed.

Squamulose

Squamulose, with minute scales.

Squarrose

Squarrose, with prominent reflexed scales.

Tomentose

Tomentose, with a dense, matted, hairy or woolly surface.

Trama

Trama, the interior portion of the gills or pileus.

Umbo

Umbo, with a prominent boss or elevation, in the center of the pileus.

Umbilicate

Umbilicate, with a minute abrupt depression in the center of the cap.

Veil

Veil, a layer of threads extending from the margin of the cap to the stem (partial veil or marginal veil). A universal veil envelops the entire plant. Veins, elevated lines or folds running over the surface of the lamella? in some species, and often connected so as to form reticulations. Ventricose, enlarged or broadened at the middle, bellied.

Vesiculose

Vesiculose, full of small rounded vesicles, as the trama of the pileus of a Russula. Volva, a wrapper or envelope, which in the young stage completely surrounds the plant, same as universal veil. At maturity of the plant it may be left in the form of a cup at the base of the stem, or broken up into fragments and distributed over the cap and base of the stem.
