Index of Subjects Hi Dave, Gloria and All Sounds like the solution to the problem. It is listed on the www in the Lichens of Romania. Not sure if it is imported or native to here. I'm not very fluent in Romanian! Its is growing in a fairly restricted area of prehaps 200m in exactly the environmential conditions Dave suggests. The growth is much more pronounced in the middle and decomes less to the east side. It is in a small cove facing north in an area where little sun shines. The cove is fairly narrow - 400m prehaps and has a small brook flowing in at the top. An interesting lichen.
