Collection location: Serra de São Mamede, Portugal [Click for map]
As mentioned at observation 203701, this is the place where Dendriscocaulon umhausense grows abundantly. Here the trees are old specimens of Quercus suber and other oaks. Their barks are full of lichen. Some examples of lichen genera are:
Collema, Degelia, Fuscopannaria, Leptogium, Lecanora, Lobaria, Nephroma, Parmotrema, Parmelina, Peltigera, Pertusaria, Physcia, Pyrrhospora, Ramalina, Sticta, Usnea,
but the most developed community is by far of Physconia.
In my previous observations I noticed that Dendriscocaulon umhausense appears in association with (or parasitizing) species of this genus, which seems evident here. It also appears growing on the thallus of Lobaria amplisima (the commonly referred host) and Parmelina carporrhizans, as shown in the attached photos .
