Growing in the bark/wood of Olea europaea.
I'm out of my place without any suppoting literature and was not able to find a species with the features of this speciemen, that can be read from the attached photos, namely discs open and pruinose and 3- septate spores with dimensions aroun (not measured) 16 x 5 um.

On the ground small, about 5mm in diameter grey apothecium with think marginal hairs. Hairs without roots, up to 650um in length.
Asci 8-spored, operculate with prominent croziers, IKI-.
Ascospores ellipsoid with 2 large guttules and many medium and small, smooth in LCB, measure
(18.3) 18.8 - 19.9 × (9) 9.2 - 9.8 (10) µm
Q = (1.9) 2 - 2.1 (2.2) ; N = 11
Me = 19.3 × 9.5 µm ; Qe = 2

Paraphyses cylindrical, septate with VBs.

On the ground next to Scutellinia sp..
This has a bit larger spores than what I usually see.
Ascospores measure
(20.7) 21 - 23.4 (23.6) × (20.4) 20.5 - 22.4 (22.9) µm
Q = 1 - 1.05 (1.1) ; N = 13
Me = 22.3 × 21.8 µm ; Qe = 1
Spikes up to 5um.

Growing on calcareous rocks at a very curious habitat (see the attached photo): These type of rocks are called "lapiás" in Portuguese, lapiaz in French from where it is originary, but in English it has no specific neme known to me; the best I obtained was: "Limestone pavement". My subsequent observation in rock this day where from this habitat.

The main question for the classification of this specimen is to decide if the fruit bodies are apothecia or perithecia. The close up superimposed to main photo permits to conclude that we have perithecia here. Then clearly the option is Verrucaria baldensis (= Bagliettoa baldensis).

On unidentified well rotten wood very likely conifer, quite possibly Picea marianea

small somewhat truncate conidia measuring 3.8 - 4.5 x 1.5 - 2.2 (on natural substrate)

conidogenesis originally thought to be annellidic, but shown to be phialidic with DIC.

Teleomorph not observed, but I have not looked very much for it yet.
