Fermin PancorboHi evrybody,

Apothecia 7-15mm in diameter, on a small slope of a mountain stream to 1826 m. in altitude between roots of Juniperus communis and next to bryophytes. Stalk very short, almost hidden in the adhering earth. Smell unpleasant, sulfurous components.

Microscopy:
Spores oval, smooth, (15.8) 16.3 to 18 (18.5) x (9.2) 9.4 to 10.3 (10.8) µm, Q = (1.6) 1.64 to 1.8 (1.9), N = 62;I = 17.2 x 9.9 µm; Qe = 1.7, enveloped in a mucilaginous sheath (0.9) 0.95 to 1.5 (1.7) µm;Me = 1.2 µm.


Asci no amyloid, 266.8 to 295.9 x 13.2 to 15.2 µm; I = 282.6 x 14.4 m. Bifurcated or single base.


Paraphyses filiform, septate, slightly widened at apex, often with diverticulate growths.


Marginal hyphae septate, sinuous and rather variable morphology, apex widened, more or less diverticulate (3.8) 3.9 to 6.9 (7.7) µm thick.


Texture of two types: under hymenium, texture intricata from 160.9 to 181.7µm formed by hyphae (4.5) from 5.1 to 8 (9.4) ?m. Then, texture
globuloso-angularis 90.7 to 102.89 µm, with elements of (17.3) 19.2 to 27.7 (28.8) µm in diameter.


According to the work "GARNWEIDNER, E., T. R. LOHMEYER, H. MARXMÜLLER (1991) Vel-Geopysis foetida., G. Alpine v. Taxa nahestehende und Höhnel - mehr als Fragen Antworten", mucilaginous sheath of spores and stipe barely evident, appears to be an important element that distinguishes Geopysis alpina.

My spores measurements are somewhat larger than those defined in this work, but I do not know how important it can be.

I would like to seek your opinion on this collection.

Re : Geopysis
Sorry!!

I have write Geopysis instead of Geopyxis!!

Re : Geopysis

Hi Fermin.
This collection enters in the alpina/foetida complex. I sequenced collections with and without smell, and all are the same...

Re : Geopysis
Thank you very much, Nico.
I'm afraid that.
