Fig. 1. Lepiota rufipes (natural size), cutieular elements and spores (1000 x) ture, however, shows the measurements to be of no help in the differentiation. L. rufipes is not always so small, the diameter of its pileus may measure up to 2,0 cm and the measurements of the spores also vary between 2,7—5x2—3,2 p. There is thus no sharp limit in the measurements between the two species. The specimens collected in Hungary may even outdo the highest limiting measurements of L. neophana as regards measurements of pileus and stem, their spores, however, conform to those of L. rufipes. KÜHNER & MAIRE (1937) write about this problem as follows: "Parmi les espèces nord-americaines, le L. neophana MORGAN, se distingue de notre plante par sa teille plus grande et par la présence d'un anneau". This remark is in complete harmony with our specimens, because relatively greater specimens also occurred among them, and ring was also observed. In spite of that, however, it would be erroneous to identify our fungi as L. neophana, or establish the identity of the two species without knowledge of MORGAN'S description for SMITH'S (1954) following remark concerning colour of the gills: the colour of the gills of L. rufipes is "white", and that of L. neophana "white at all times". Nevertheles, though the gills of our fungi are whitish or whitish with a shade of rosy, later they become dirty light ochre and in the herbarium light milkcoffeecoloured, and this colour of the gills is — according to the European literature — characteristic of the not white-spored L. rufipes. JOSSERAND has kindly examined our duplum material and also he takes it for L. rufipes. Description : Pileus 0,8—2,5—(3,4) cm in diameter; first nearly hemispherical-convex or gibbous, finally nearly flattened ; margin white-whitish or else creamy-light carneous, its center ochreous-brownishcarneous or somewhat rusty; surface smooth, or only the center of the pileus is smooth and the cuticle of the pileus disrupts into small areolae towards the margin. Gills free, distant from the stem; fragile; in the juvenile specimens whitish or whitish with a rosy hue, later dirty light ochreous, and in the case of herbarium specimens light milkcoffeecoloured; 1,5—3—(4) mm wide. Stem 2—3,5—(5)x0,l

—0,3 cm ; equal ; sericeously shining ; whitish but the colour of the flesh is rosily visible through it, with the older specimens wine-reddish to brownish; its under part more or less fibrous; occasionally with white rhizoids at the base. In a number of fungi the ring is not or
