Description : Pileus 1,3—4 cm in diameter ; convex, more or less gibbous, then expanded, however, with a small gibbosity on its center; circular or irregularity shaped; whitish to isabel-coloured, ochreous or light orange, the middle part with a little darker shade ; the margin may be undulate-lacerated, occasionally splitted, in juvenile state markedly floccose; occasionally finely costate; the cuticle of the pileus smooth or finely granulose-floccose, in places disrupting into fine small squamules. Gills free; whitish or with a shade of pale isabel-colour or light ochre. Stem 2,5—5—(7)x0,2

—0,4cm; equal; above whitish, down isabel-coloured; covered with cotton-wool-like flocks. Flesh is very thin towards the margin of the pileus ; becoming tubular in the stem; its colour in the crust of the stem with a shade of pale rusty-orange. Smell agréable. Spores elliptical to spindle-shaped, measuring 11,7—14,7—(15,6) x 4,7—5,4 p. In the Lepiota section this is the most frequent species after L. clypeolaria (BULL. ex FR.) KUMMER. It is not, however, regarded common but rather fairly rare by a number of European authors. Its habitats may be diverse. It occurs primarily on grasslands, meadows, pastures, occasionally in forests too. It was collected by KÜHNER (1936) in the subalpine, alpine region, and was described by PILÂT (1969) as one growing on calcareous steppe. LEBEGYEVA (1949), on the other hand, describes it as a fungus growing in kitchen-gardens and on dunghills. Most data on its occurrence in Hungary originate from the Hungarian Plain (at 108 — 168 m height above sea level) i.e. pastures, locust-tree woods, oak-forests, was, however, also found in the meadows and grassy forests of both the Transdanubian and Northern Central Chain of Mountains.

The pilei of the collected fungi are white-coloured, the centers are slightly creamy-yellowish to pale ochreous, the stem is w ite, whith cotton-wool-like coating, becoming bared. At the margin of its floccose-membranaceous ring occasionally a yellow-ochreous pattern is seen. The measurements and morphological features of the fruit-bodies conform to the data in the literature but for differences in the limits of measurements of spores. This is illustrated by the following brief composition: Lepiota alba (BRES.) SACC. REA (1922) KAUFFMAN (1924) BRESADOLA (1927) LANGE (1935) 11— 14x6—7 p 12— 14x6—7/1 12— 14x6—7 p 10,5—14x5,5—6^
