Syn.: Cladina arbuscula (Wallr.) Hale & W. L. Culb., Cladonia sylvatica auct., non (Ach.) Rabenh.

All the records of this taxon from the area of study are likely to belong to C. arbuscula subsp. squarrosa, but a chemical study of the whole material still has to be done. The subsp. arbuscula is an alpine taxon, which is unlikely to occur in the study area.
