I do not think i have ever seen this "for real" so to say, i
do believe i have only seen this type of moss in books.
I saw i today when i was walking around the lake. It really
does look like a group of teeny tiny cups.
Cladonia or cup lichen (bekermos / begerlav) is a genus of
moss-like lichens in the family Cladoniaceae. They are the
primary food source for reindeer and caribou. Cladonia
species are of economic importance to reindeer-herders
such as the Sami in Scandinavia. The light green species
Cladonia stellaris is used in Christmas decorations.
