KÜHNER (1936) LEBEGYEVA (1949) KÜHNER & ROMAGNESI (1953) MICHAEL & HENNIG (1964) MOSER (1967) 11,5—15 x 5,5—6,5—(7,2) p 11—15x6—7^ 10,5—15x5,5—6,7 p 12—14x5,5—6,5^ 12—14x5,5—6,5 p Hungarian material 9,3—10,9—14,8—(17) x 4,7—5,4—7—(7,8) p, which shows that the limits of measurements are wider than those found in the literature, and besides certain differences in measurements were also observed between fungi from the Great Hungarian Plain [11,7—15—(17) x 5,4—7—(7,8) /j] and those from the Central Chain of Mountains (9,3—14,8x4,7—7 p), out of which the fruitbodies originating from the Csúcshegy had the smallest spores. BARLA' S (1889, Pl. 10. Figs. 5 — 8) fungus which has a brown and squamously disrupting pileus strongly differs from the light, whitish-ochreous (BRESADOLA 1927, PI. 22; LANGE 1935, Pl. 8/A; PILÁT & USÁK 1961, Pl. 146; ROMAGNESI 1961, Pl. 194) or light brownish (COOKE 1881-1884, PI. 23;MAUBLANC 1946, PI. 17) excoriata. BARLA'S fungus has been only questionably regarded as M

. excoriata by LOCQUTN (1952). In the literature there are no comments on the fungus with a brown, squamous pileus described by WAKEFIELD and DENNIS (1950, PI. 5, Fig, 2). Not only the colour of the pileus varies between white and brown, but h the grade of disruption of the cuticle may also be different, the cuticle splits generally •— often radially — only at the margin of the pileus, whereas with other specimens the pileus is decorated, apart from the central part, with squamules or squamae (KÜHNER 1936, Fig. 3C, 4C; MICHAEL & HENNIG 1964, Fig. 13). MAIRE (1928), on the other hand, separated specimens with erect squamae under the name Lepiota excoriata var. squarrosa. Fig. 6.
