Remarks (internal):Entoloma minutum can fairly easily be identified in the field because of its small, slender, pallid fruitbodies and strongly translucently striate pileus. It is a common species in moist forests, and occurs from the lowlands in various types of forest up into subalpine Alnus viridis stands as well as in subarctic Betula copses.

Tipizzazione - Holotypus: non esiste; località di raccolta del tipo: Mustiala, S. Finlandia.
frequently also with slight central depression, with straight margin, hygrophanous, when moist translucently striate up to centre, pallid brown, pinkish brown or yellow brown, paler towards margin, strongly pallescent upon drying to pale cream, pale brown or almost white, smooth, silky shining when dry, sometimes radially fibrillose under lens when dry. Lamellae, L = 10-25, l = 1-3, distant, veriably inserted from almost free, emarginate to (broadly) adnate or subdecurrent, triangular to ventricose, white then pale pink with concolorous, entire edge. Stipe 20-70 x 0,5-2 mm, cylindrical, sometimes slightly broadened towards base, hyaline yellowish or brownish, paler than centre of pileus, glabrous, polished or with some scattered fibrils lengthwise, never distinctly striate, often minutely pruinose at apex, base with white tomentum. Context very thin and fragile. Smell weak. Taste mild.
Spores 8-11(-11.5) x 6.5-8.5(-9) µm, Q= 1.1-1.4, subisodiametrical to slightly heterodiametrical, rather regularly 5-7-angled in side-view. Basidia 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis a thin cutis of narrow, cylindrical hyphae, 1.5-10 µm, wide. Pigment pale, minutely encrusting in pileipellis and upper pileitrama, in addition sometimes also a very pale, diffuse intracellular pigment is observed in lower pileipellis. Clamps present in hymenium, elsewhere rare. Habitat: In deciduous forest, often on damp places with Alnus, Fraxinus, Betula, and Salix, also in moist grassland; summer-autumn.
Distribution: Wide-spread all over Europe, fairly common.
