Ramsbottomia crec'hqueraultii 280815 287

Hi friendsI have this Ramsbottomia with rounded spores and mixed characters between R. crec'hqueraultii and R. macracantha.
Spores (1000x, H2O, live, without ornamentation): (19,2) 20,3 - 23,4 (23,6) × (19) 20,2 - 22,7 (22,9) µm; Q = 1 ; N = 37; Me = 21,8 × 21,4 µm; Qe = 1.
Ornamentation length: (2,2) 2,6 - 3,9 (4,2) µm; N = 45; Me = 3,3 µm.
I think it is nearest R. crec'hqueraultii than macracantha because Me spores are 21,8 x 21,4 (only a little bigger than 20 µm) and ornamentation is Me = 3,3 µm, but all papers I have read have spore measures for crec'hqueraltii < 20 µm and spiner never > 3,5 µm. And in this collection some spines have a very broad base.
Perhaps my collection is a "joung" R. macracantha?
Thank you in advance.

Hi Miguel.
You lost your Cotton Blue ;-)
It would be interesting to know more about the other characters, especially the "hairs", and the habitat.

Re : Ramsbottomia crec'hqueraultii 280815 287
Jejeje, don't worry Nico, next time, despite this impressive ornamentation, I will use CB, CRB or another blue.
This Ramsbottomia was neighbor of Boudiera tracheia, at alpine place, in a very, very humid slope of a small stream, between mosses, with Juncus, Aconitum and another small herbs.
An this are the pictures.

Hi.
In alpine zone, the most common species is R. asperior, but the spores of this collection seem to be too large (and not enough subglobose) to fit the latter.
R. lamprosporoidea is another hypothesis, but the "hairs" should be more coloured and longer (I think you remember our discussion about this taxon and some Pyrenean collections).
In all cases keep this collection, a DNA sequence could be useful to clarify the taxonomy of each taxon...

Hi Nico
We have a collection of R. lamprosporoidea published in "Contribución al conocimiento de la micobiotal de Parque Natual de la Sierra Norte de Guadalajara. Catálogo y especies más interesantes I. Bol. Soc. Micol. Madrid 38: 163-181. 2014" (link here: https://www.dropbox.com/s/kilf85z3nt3683z/Contribucion%20conocimiento%20micobiota%20del%20PN%20Sierra%20Norte%20de%20Guadalajara%20-%20Campos%202014.pdf?dl=0):
* with subglobose spores, not rounded, (16,1-)16,9-18,9(-19,3) x (13,8-)14,8-17(-17,4) mµ Q = (1-)1,05-1,18(-1,2); N = 41; Me = 17,9 x 16 µm ; Qe = 1,1.
* with darker hairs of (72,3-)103,5-134,9(-162,3) x (11,7-)13,3-22(-24,3) µm; N = 34; Me = 118 x 17,5 µm
The length hairs is similar in both collection, but not the spore shape.
We could try to sequenced it.
Thank you.
