Mycena renati: The Ultimate Mushroom Guide
About The Mycena renati Mushroom
Mycena renati is a species of mushroom in the family Mycenaceae. The cap is reddish-brown initially conic or parabolic but expands somewhat in maturity to become convex, and typically reaches dimensions of up to 3.2 cm (1.3 in).
The color of the lamellar edge often is absent or hardly noticeable, or only visible near the margin of the pileus. It is easily identified because of the red-brown pileus and the bright yellow stipe. Microscopically the inflated excrescences of the hyphae of the pileipellis should be noticed as a reliable character.
It was described by French mycologist Lucien Quélet in 1886. It has been collected in Austria, Uşak Province in Western Turkey, and Yugoslavia.
Other names: Beautiful Bonnet.
Mycena renati Identification
10-32 mm across, conical, parabolical, finally convex, pruinose, glabrescent, shallowly sulcate, translucent-striate, at first dark reddish-brown, becoming paler reddish-brown to pinkish brown, darker at the center.
16-20 reaching the stipe, ascending, adnate, decurrent with a short tooth, becoming dorsally intervenose with age, dingy white; the edge concolorous or reddish-brown.
15-65 x 1-2.5 mm, hollow, straight to curved, equal, terete, pruinose, glabrescent, bright yellow, turning brown from the base with age; the base covered with white fibrils.
Indistinctive to weakly nitrous.
25-31 x 7-10 µm, clavate, 4-spored, with sterigmata up to 8 µm long. Spores 8-10.2 x 4.9-6 µm, Q = 1.4-1.8, Qav = 1.6, fairly broadly pip-shaped, amyloid.
34-63 x 8-14 µm, forming a sterile band, fusiform, rarely lageniform or clavate. Pleurocystidia similar, if present. Lamellar trama dextrinoid.
Hyphae of the pileipellis
2.5-12 µm wide, smooth or covered with coarse, rounded, mostly inflated excrescences 8-22.5 x 5.5-13.5 µm. Hyphae of the cortical layer of the stipe 2.5-3.5 µm wide, smooth or covered with scattered rounded warts, clamped, the terminal cells coarsely diverticulate.
