The fungus resembles — among others — H. mesophaeum (PERS. ex FR). QUEL., but differs by the following characteristics: I. spores larger; 10-13 p. long, 2. colour of gills tinged carneous; 3. colour of pileus usually lighter than in mesophaeum; 4. stem not rarely more or less thickened (to even 1.3 cm) : cap of such specimens frequently as wide as length of stem. An excellent illustration is given in KONRAD & MAUBLANC (1924-1930), tab. 78(1), and a poorer figure in COOKE (1884-1886), tab. 451/410. sub nom. H. claviceps Fr. It is also similar to H. versipelle (FR.) GILL. SS. ROMAGN., described in 1965, in which, however, the colour of the gills lack the carneous tinge, the stem is rather short, the stature resembles that of Pholiota carbonaria, and the spores are small (7.7-9.2 jx). Description : Pileus 2.5-6 cm in diam. ; convex-expanded, occasionally gibbous, at length also depressed; in wet weather moderately viscid; especially margin covered with fibrillose velum ; rusty brownish, clay-coloured, rusty ochre or brownish ochre; margin occasionally lighter and centre rusty brown, reddish brown or
