Small but perfectly formed

Post by Paul Cannon » Tue Aug 06, 2019 3:40 pm

Hello all
Looking through a collection of bits and pieces from Dartmoor, I came across a fertile thallus of Cladonia portentosa. Not something I've seen before, apothecia aren't mentioned at all in LGBI2 and are noted as infrequent in the Nordic flora. Have I just not been looking beyond the gross thallus features, or are they genuinely rare? They measure between 100 and 150 µm diam., some of the smallest apothecia I've ever seen.

Best wishes
Paul

It is sometimes fertile in the north Pennines, but not often.

How about Pseudevernia, has anyone come across that fertile in England? We found it in Allendale a few days ago and it was the first I have seen. There are records in the BLS database from Scotland but only one I can find from England, near Shap back in 1992.
