Psathyrella abortiva A. H. SMITH (Fig. 3.) SMITH described this well characterizable Psathyrella , collected on a single occasion in the USA, in his monograph published in 1972. I succeeded to collect its white fruitbodies, richly covered with filamentous and floccose squamae, on one occasion, when they appeared in abundantly near Horány (13 June, 1975), but the small, irregularly shaped, 1-5 mm large tubers in an abortive state could be subsequently observed for nearly two months. Unfortunately, no further observations could be made, because the collecting locality was annihilated by forestcultural work. Psathyrella mar ce s cibilis (BRITZ. ) SINGER f. virginea LANGE (Fig. 4.) Among the many Psathyrella species , characte ristic to the woods at Horány, this fungus with a creamy white cap, completely white gills, and of a Mycena habit was very conspicuous. Its relegation to the genus Psathyrella was indicated mainly by the crenellate remains of the velum hanging from the edge of the cap; the gills were not discoloured at all. Some specimens grew along a drive on the edge of a locust-tree wood. Panaeolus guttulatus BRES. (Fig. 5. ) On the basis of BRESADOLA' s (1881, 1931) and HEIM - REMY's (1926) descriptions and figures, this small fungus with dark oil brown to blackish brown cap can be easily identified. The edge s of its gills , turning black in time , is light, with small, dry guttae. When young, the stem is finely farinaceous. It grew on three occasions in a forest settlement, near a garbage compund, and in a mixed forest. Resupinatus trichotis (PERS. ) SINGER (Fig. 6. ) The resupinate or obliquely grown small fruitbodies are brownish-grey to blackish, the middle of the cap felty-velutaceous-hirsute . The colour of the filiform cap hairs are darker under the microscope than those of the other species with sphaerical spores ( R. applicatus) . The collected specimens completely agree with LANGE's excellent illustration (1936, 66 A). The fungus grew on a fallen, decaying twig in a mixed forest.
