Gallé, László: The xerothermic lichen species cladonia magyarica VAIN

of wich some collectors had classified the Cladonia magyarica forms into other Cladonia species (e. g. Cladonia pyxidata f. neglecta). During our investigations we have carried out the separation of these forms, distinguishing six well-separable forms and apart from them one teratologic case. The identity of the fungus and alga components has been considered as a common mark characteristic of the whole species, being able to be decided by reason of the construction, shape and size of the spores and gonidia. There were regarded as a common mark also the internal construction of the primary thallus and of the podetia, as well the reactions of the thallus and podetia to KOH, CaOCl

2 and paraphenilendiamine. We have regarded as a mark of form also the external shape of the thallus, the form of its position on the substratum, the colour of thallus, the external construction of podetia, being simple or composed, the degree of their being laced, the location of lacings, the differences concerning the crustation of podetia. Moreover, we have distinguished the sterile and fructificativous forme that are always differing from each other. Already I. PISÚT (1961:370) had distinguished an irregular form in connection with the regeneration. That is showing so great differences that, if not found in the thallus of Cladonia magyarica, we should not believe it to belong to this species. Taking into consideration the differences mentioned above, we have prepared the clue of variations and forms of the species Cladonia magyarica, in English (a) and in Latin (b) languages: (a) Clue of variations and forms of the species Cladonia magyarica VAIN 1 a The podetia are assurgent 2 b The podetia are procumbent, from their sides new small funnels are germinating 8. ter. setigerus 2 a The podetia are simple 3 b The podetia are proliferating repeatedly, in storeys 5. f. verticillata n. f. 3 a The plants are sterile, without apothecia 4 b The plant are producing abundantly. The podetia have a lot of apothecia, in young age light brown later on dark brown ones 6. f. carpophora n. f. 4 a The funnel is bunch-like foliose. Typical form. 1. var. magyarica b The funnel is foliose not bunch-like 5 5 a On the edge of the funnel there are sitting tiny shoots 3. f. proliféra n. f. b The edge of the funnel is not germinating 6 6 a The primary thallus is well developed, spherical, pressed strongly to the substratum, in the middle it is brownish, towards the edges it is lighter, growing generally on moss grass. The podetium is short, trumpet-like, with a narrow orifice 6. f. pocilliformis (VAIN.) PISÜT b The primary thallus is weakly developed, the podetium is oblongcylindrical, widening out moderately, sparcely It is rather verrucous, rimous 7. f. truncata n. f. 253
