Gallé, László: The xerothermic lichen species cladonia magyarica VAIN

A Móra Ferenc Múzeum Évkönyve (MFMÉ) 1968 THE XEROTHERMIC LICHEN SPECIES CLADONIA MAGYARICA VAIN A history of investigation The typical form of Cladonia rnagyarica was first collected by J. BERNÁTSKY in the Danube island Csepel, in a sand soil, in 1901. The specimen collected by him is placed in the herbarium of the Hungarian National Museum, denominated Cladonia pyxidata var. neglecta, determined correctly by O. SZATALA during the revision of the herbarium in 1929. A datum still older is I. RICHTER's collection from 1885, containing a specimen of Cladonia magyarica f. pocilliformis from Pokorágy, in county Gömör. That lichen has got into the herbarium of the Institute of Plant Taxonomy of the Lóránt Eötvös University under the name of Cladonia pyxidata, revised similarly by Ö. SZATALA. These are, therefore, the oldest herbarial data concerning the forms of Cladonia magyarica. In the period between 1885, resp. 1901 and 1924, the typical form was found by a lot of botanists, among them also by Hungarian lichenologists of repute (GYELNIK, SÁNTHA, SZATALA, TIMKÓ), in the quicksand regions of the Great Hungarian Plain, and one of the variations was found even in Transdanubia, i. e. in the part of the country that lies between the Danube, the Drava and the western frontier, without being recognized by the collectors as a new species. On the labels of the most specimens in the herbaria the name Cladonia pyxidata var. neglecta is given. At last in 1924, GY. TIMKÓ found some conspicuous specimens in the wood „Bugacz" near Kecskemet, and being unable to determine them he sent them to the excellent Finnish Cladoniaspecialist, E. VAINIO. VAINIO immediately recognized them being new plants, determining their taxonomic place betwen Cladonia pyxidata and Cladonia chlorophaea. In 1929, he described them as nova species, giving them the name of Cladonia magyarica. A variation similar to the variant named Cladonia pyxidata var. pocillum, the Cladonia magyarica var. pocilliformis, has been separated from TIMKÓ's material similarly by VAINIO, as well. The variant is regarded by I. PISÚT (1961 : 370) to be but of formal value and mentioned as a new combination by the name f. pocilliformis (VAIN.) PISÚT. The original specimens of both forms are preserved in the botanical collection of the National Museum of Natural Sciences (Budapest) with E. VAINIO's autographic signature „Exemplum originale" and his autograph. In 1930, V. GYELNIK (1930 : 22-23) published a detailed description of the lichen and the localities of occurrence of the type plants. Both the exsiccatum and VAINIO's original diagnosis appeared in the publication of the Botanical Collection of the National Museum (Cent. VIII. Lichenes 75. No. 715) in 1930. In the same year J. ANDERS (1930 : 499-501), and in the next one H. SANDSTEDE (1931 : 410-411) dealt with Cladonia 237
