Pileus 1–2 cm, plano-convex to applanate, dry, light yellow, yellow to dark yellow (2 A 6–2 A 7, 4 A 5–4 A 8), ornamented with minute, concolorous scales. Lamellae narrowly adnate to sinuate, up to 1 mm broad, close to crowded, light yellow, yellow to dark yellow (2 A 6–2 A 7, 4 A 5–4 A 8), with abundant lamellulae. Stipe 1–4 cm long, 0.1–0.3 cm thick, cylindrical, light yellow to yellow (2 A 6–2 A 7, 4 A 5) with minute, pale yellow (1 A 2–1 A 3) granules. Partial veil cortinate, white (1 A 1), membranous-floccose, leaving remnants on the stipe surface as thin, fibrillose-flocculent patches.</p><p>Basidiospores [60 / 3 / 2] 5.0–5.9 (– 6.2) × 4.9–5.7 (– 5.8) μm, Q = (0.91 –) 1.00–1.06 (– 1.07), Q av. = 1.02 ± 0.03, globose, thin-walled, colorless and hyaline, smooth, non-amyloid; apiculus small. Basidia 15–40 × 5–6 μm, 4 - spored or 2 - spored, narrowly clavate to flexuose, thin-walled; sterigmata 3–5 μm long. Cheilocystidia 35–40 × 15–32 μm, broadly clavate to spheropedunculate, colorless hyaline, abundant, forming a sterile belt along the lamellar edge. Pleurocystidia absent. Pileipellis a cutis with the transition to a trichoderm at regular intervals, 20–40 μm thick, and composed of radially arranged, thin-walled hyphae 5–12 μm wide and encrusted with brown pigments.

Bambusinae. It resembles these species in having yellow-toned basidiomata and a general association with bamboo-related substrates but differs in possessing a well-developed cortinate annulus on the stipe and distinctly smaller basidiomata. Microscopically, T. cortinata is distinguished by globose to subglobose basidiospores, whereas those of T. bambusina and T. sasae are typically ellipsoid. Cheilocystidia in T. cortinata are broadly clavate to spheropedunculate and form a well-defined sterile lamellar edge, while those of related species are generally narrower and differ in shape. The presence of a cortinate annulus represents an unusual feature within Tricholomopsis and further distinguishes T. cortinata from previously described species.</p></div>	https://treatment.plazi.org/id/A3DF68F6B4A85895BB698D7127A5974A	Public Domain	No known copyright restrictions apply.

It resembles T. rutilans in having brightly colored basidiomata with a squamulose pileus and stipe but differs in its smaller basidiomata, finer grayish-rose to ruby-red squamules, and cheilocystidia often containing brown vacuolar pigments. It is also similar to T. flammula and T. pteridiicola in pileus coloration but differs in having a larger pileus with denser and more vividly colored squamules, broader basidiospores, and less frequent pleurocystidia. T. roseorubra can be distinguished from T. depressa by the absence of a distinctly depressed pileus, ellipsoid to broadly ellipsoid basidiospores, and predominantly clavate cheilocystidia with brown vacuolar pigments, whereas T. depressa has more elongate basidiospores, spheropedunculate and typically hyaline cheilocystidia, and more frequent pleurocystidia.</p><p>Ecologically, T. roseorubra appears to be associated with decaying bamboo leaf litter in montane habitats, which may further distinguish it from most other members of the section.</p></div>	https://treatment.plazi.org/id/1EA175D1E94F5873BD15FEF2AB1EA734	Public Domain	No known copyright restrictions apply.
