Observation 74960: Cladonia apodocarpa Robbins
When: 2011-08-07
Who: zaca
No herbarium specimen

Notes: 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).

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.
