Lőkös, László: Lichens on Fumana I. An investigation on herbarial sheets

- Of the approximately 60 Fumana sheets collected in rocky grasslands virtually none had epiphytic lichen vegetation. This requires further studies on living Fumana stands. - Do dwarf shrubs other than Fumana in herbaria have similar epiphytic lichen vegetation? - Living Fumana procumbens stands found in countries other than Hungary should be investigated whether they have similar or different epiphytic lichen vegetation.
