Pulvinula 051225 273

Miguel Ãngel RibesGood afternoon

I'm completely baffled by this supposed *Pulvinula* due to its discoid to pulvinate apothecia, the lack of guttulation of the ascospores, and the thickened paraphyses at the apex.

It was growing on soil with some mosses, in calcareous soil that may have been burned some time ago, but I can't confirm the latter.

Apothecia 1-1.5 cm, discoid to pulvinate, not cup-shaped, without a differentiated margin, bright orange in color.


Asci cylindrical almost to the base, with croziers, octosporic (although many of them with 4 aborted spores), inamyloid, (197) 213 - 254 (257) × (21.6) 24.3 - 29.5 (30.5) µm; Q = (7.4) 7.8 - 9.8 (10); Me = 233.1 × 26.7 µm; Qe = 8.8.


Ascospores spherical, hyaline, without ornamentation nor apparent guttules, (14.1) 15–17.1 (17.4) × (13.5) 14.2–16.4 (16.9) µm; Q = 1–1.05 (1.1); N = 51; Me = 15.9 × 15.5 µm; Qe = 1.


Paraphyses cylindrical, multiseptate, straight, apparently not bifurcated, with the apex thickened to (7.4) 8.8–11.3 (11.8) µm; Me = 10 µm.


Ectal excipulum with textura angularis, medullary excipulum with textura intricata.


Using these characteristics and Moyne's keys, I arrive at P. cinnabarina (but this one would have longer and narrower asci), P. convexella (also with narrower asci), P. miltina (perhaps the best fit), P. carbonaria (also a good fit), and P. globifera (with smaller spores).


Thank you for your help.
