Lecidoma again?

The appearance is a bit different from the one in observation 201834 but what I could see from the sections is very similar. This time I could see more spores with dimensions: 10.4 – 13.4 × 4.8 – 5.6 µm.
The different appearance could be explained by the habitat? The one in observation 201834 grew in a siliceous habitat completely exposed to the natural elements, while this one lived in a shadow place, a man-made wall inside a village.
It should be mentioned that the spores are a bit smaller than the indicated for Lecidoma demissum (the only species in the genus) in the British Flora: 12 – 16 × 5.5 – 7 µm.

Neat, I can’t wait to find out what this is
