location
Bovec basin, southeast of village Čezsoča, dirt road side leading to former ski lifts, East Julian Alps (Posočje, Slovenia)notes Syn: Opergrapha persoonii (Ach.) Chev., Opergrapha parasitica auct. - Habitat: rocks of a dirt road scarp; humid and shady place; mixed forest and grassland around, no insolation during winter months; often wet place; north aspect; about 1.5 mm above the road level; exposed to direct rain; precipitations ~3.000 mm/year, average temperature 7-9 deg C, elevation 400 m (1.300 feet), alpine phytogeographical region. - Substratum: on Gyalecta sp. lichen; vertical, hard, calcareous rock surface. - Comment: Substratum, habitat and habit correspond well to Opergrapha rupestris. It is the only lichen of this genus which grows on calcareous rock in most cases parasitizing other crustose lichens, usually a species of Verrucariaceae, but also other lichens. Backwards analysis (backwards because of the lack of microscopic data) of the keys published in Ref.: 1, 3 and 4 show no conflicts. Ref.: 5 states several finds of Opergrapha rupestris in Slovenia, however, no finds are included in Boletus Informaticus Database (Ref.: 6). Unfortunately no chemical test and microscopy have been done. Therefore the determination remains questionable. - Ref.:(1) C.W.
