This observation is related with MO73232.

During this month I found twice specimens which I believe to belong to the same species that in that observation.
The first specimen was observed in 07/08/2011, I looked for pycnidia under the microscope and I registered the structures of this kind that I found (see the 2nd attached photo). The second was observed in 17/08/2011, it looked a bit older than the previous, and I took a detailed attention to the chemical K-reaction. Only the K-reaction in the upperface had developed, changing from a negative or weak yellow reaction to a clear K+ red-brown (from the fumarprotocetraric). On the contrary, the K-reaction on the underside remained unchanged in the course of time (see the 4th attached photo).


07/08/2011 – Pycnidia
17/08/2011 – K-reaction

it’s hard to believe that this is apothecia, because they are so small. But they have to start somewhere …
Thanks, Jason.

Those look like apothecia, not pycnidia

The pycnidia are ball-shaped to ellipsoid black things with a little hole at top. (Darn, I can’t find a photo of one anywhere.) Apothecia are very rare, but Lendemer and Hodkinson talk about them actually being minutely “stalked”, presumably just like this.
