Cladonia spp

Cladonia spp

Observation - Cladonia spp - UK and Ireland. Description: Growing on an east-facing sandy bank at the edge of a spruce plantation. I think these are two different Cladonia species. The thicker and whiter looking one with the red fruiting bodies on the right of the picture I believe to be Cladonia polydactyla.

I think the one in the foreground could perhaps be Cladonia furcata. It is fairly dry in this photo but when wet is a greener grey with a little brown towards the tips. With a hand lens it is possible to see that where it branches, mostly into two, there appears to be a hollow in the fork and that the extreme tips are very dark brown, possibly pycnidia, but too small for me to see.

Picture 2 shows it growing lower down the bank on the path edge – almost invisible in the moss and needles.
