The closing of the pedunculate plants is changing in high degree: in places lying deeper it may be as much as 80-90 p. c, on the hill-sides exposed to wind and sun, however, they are hardly covering 10-20 p. с of the soil. In the latter cases, a synusium consisting of lichens and mosses is coming into domination. It is therefore that this synusium is considered by several foreign authors (TH. MÜLLER 1951; О. KLEMENT, 1955) as an independent association under the name Cladonietum endiviaefoliae. As interpreted by R. SOÓ's Hungarian plant-sociological school, however, this association is to be regarded as synusium. Taxonomical Part Together with the typical form of Cladonia magyarica, often even in identical localities, there occur some very characteristic forms that may be recognized easily and are differing conspicously from the another. In the course of an investigation of several hundreds of herbary specimens and of several thousands of living exemplars, I have observed a lot of forms from those having but hardly laced podetia till those laced bunch-likely and superabundantly, till the funnels proliferating simply and manifoldly, on the basas 252
