Collema glebulentum (Nyl. ex Cromb.) Degel.

A sterile species with relatively wide, rounded lobes and conical, sometimes branched and coralloid isidia. It grows on humid, acidic to basic silicates, often at periodically inundated sites. Rock walls in the montane to alpine zone, humidified by flowing trickles or streams, are its typical substrates. Collema glebulentum occurs mainly in northern Europe and some montane areas. It is known only from two localities in the Czech Republic, from the Velká kotlina corrie and the Jelení hřbet ridge in the Hrubý Jeseník Mountains. In the Velká kotlina corrie, it has recently been confirmed.
