Orange apothecia 2-8 mm, on sandy roadside soil among grasses, next to a limestone quarry. 8 spored asci measuring 200 - 250. Ascus tapering towards the base, croziers present. Globose spores with a single large guttule, 12-15 microns. Paraphyses filiform, curved at the ends, filled with golden droplets, no branching, mostly 1.5-2.1 wide.

I have been reading the key from Pfister (-76) but none of the species described there seems to fit. Any opinions? Thanks.

Re : Unknown Pulvinula
Hola Henri.
En la primera imágen me parece ver restos de quemado, porqué has descartado la Pulvinula carbonaria?.
Saludos.

Re : Unknown Pulvinula
Thanks Josep. Pulvinula carbonaria is best fit following Pfister's key.  I wonder if presence of coal is necessary as I didn't see any sign of coal in situ.   There is also a previous collection of Pulvinula from the same spot (2014, identified as Pulvinula constellatio) with no mention of coal.  The spot is grassy road-side of a sandy country road next to a limestone quarry, not a probable place for camp fire.
