Cladonia chlorophaea (Flörke ex Sommerf.) Spreng.

( Fig. 11 )

NOTES

It contains fumarprotocetraric acid (itself or with related compound protocetraric acid – not analysed separately).

Their colour is pale greenish brown, the margin of the scyphi is dentate and becoming broken and denuded with age, the base

of the podetia is not melanotic ( Ahti et al. 2013). The soredia are granulose and thus measured as relatively larger (34-138µm) than in other species in Hungary. It has relatively tall (3.6-20.8 mm) and broad (1.1-7.9 mm) scyphi with short stalk. Differences were found from C. asahinae in several characters ( CH, CW, PH, PHCW, sor, SW), from C. cryptochlorophaea in height of cup and podetium, from C. grayi in the height of podetium, from C. merochlorophaea in the length of squamules and from C. novochlorophaea in the height of the podetium ( Table 1 ).

It is the most frequent and most widely spread species in Hungary among the C. chlorophaea s.l. species. C. chlorophaea is found on calcareous soil, in deciduous and coniferous forests, at the basis of various tree species (e.g. Alnus glutinosa (L.) Gaertn., Betula pendula Roth , Fagus sylvatica L., Quercus spp. , Robinia pseudoacacia L.), sometimes on stumps on lignum or thatched roof and almost equally frequent in the Hungarian Great Plain (70-200 m a.s.l.) and in hilly regions (up to c. 1000 m a.s.l.) in Hungary. However, specimens from hilly regions were mostly recognised as other C. chlorophaea s.l. species during our revision.
