Notes: This specimen was growing isolated in an old concrete wall, now dilapidated and invaded by vegetation, which surrounds a property. When I saw it I was immediately reminded of a species that found a couple of months ago -Plectania rythidia.
Both the macroscopic and microscopic features that I managed to get match with this species originating from Oceania: spores of ellipsoidal shape, as it streaked across, with an average size of 21.8 – 24.9 × 10.1 – 11.8 µm (Qe = 2.2, N=52), paraphyses very long and thin. Only habitat (at first sight) does not coincide, since I do not remember having seen nearby trees of the genus Eucalyptus with which this species is normally associated.

I am not an expert in Sarcosomataceae, but according to the microscopic characteristics, I think it is Plectania rhytidia. There are two other quite similar looking species: Plectania mediterranea and Plectania zugazae:
What is interesting to me, is the nutrient-poor substrate (concrete wall covered by moss). I wonder if that species is maybe a saprophytic AND (optional) mycorrhizal fungi.
I have described the facts. I can say nothing about what is beyond my scope of observation, I can only presume. Did you found anything wrong with the identification?
Interesting substrate! I wonder if the mushroom absorbs nutrients from the concrete wall too (Calcium, Iron, Sulfates) ?
