Esta especie está recogida sobre pequeñas ramas muertas de boj (Buxus sempervirens) en praderas semialpinas en el Pirineo aragonés. Apotecios de aproximadamente 1 mm, estipitados, blanco-cremoso, tanto el himenio como el exterior.
Ascas con croziers y ápice azul con IKI, de (67.6) 73.8 - 87.5 (90.4) x (5.4) 5.6 - 7.1 (7.6) µm
Q = (10.8) 11.2 - 13.8 (15) ; N = 25; Me = 80.1 x 6.4 µm ; Qe = 12.5, en agua, a partir de material fresco y a 1000x.
Esporas cilíndrico-fusiformes, ligeramente alantoides, atenuadas en los extremos, con 1 septo en la madurez y aparentemente sin gútulas, de (15.5) 16.4 - 19.3 (21.3) x (1.9) 2.1 - 2.7 (2.8) µm
Q = (6.5) 6.7 - 8.6 (9.1) ; N = 51; Me = 18.1 x 2.3 µm ; Qe = 7.8, en agua, a partir de material fresco y a 1000x.
Paráfisis cilíndricas y con numerosas gútulas
Muchas gracias,

Asci with croziers and blue apex in IKI, (67.6) 73.8 - 87.5 (90.4) x (5.4) 5.6 - 7.1 (7.6) microns
Q = (10.8) 11.2 - 13.8 (15), N = 25, Me = 80.1 x 6.4 microns, Qe = 12.5, in water, from fresh material and 1000x.
Spores cylindrical-fusiform, slightly allantoid, attenuate at the ends, with 1 septum at maturity and apparently without guttules, (15.5) 16.4 - 19.3 (21.3) x (1.9) 2.1 - 2.7 (2.8) microns
Q = (6.5) 6.7 - 8.6 (9.1), N = 51, Me = 18.1 x 2.3 microns, Qe = 7.8, in water, from fresh material and 1000x.

Re:Crocicreas aff dolosellum
Dear Miguel
I think this is Cyathicula fraxinophila on Fraxinus petioles. What do you think?
Did you collect it now? It is an autumn species.

Re:Crocicreas aff dolosellum
Dear Zotto
I think it fits perfectly with your C. fraxinophila plate, but in this case it was growing in dead twigs of boj (Buxus sempervirens). This collection is from Pyrenees, 12/10/2010.
Today, is it Cyathicula or Crocicreas?
Thank you,

Re:Crocicreas aff dolosellum
For me it is Cyathicula, others prefer Crocicreas.
Could you please find out if there is any Fraxinus in this subalpine area? Your photo decidedly looks lek Fraxinus petioles.
You mean 12. Oct. (or 10. Dec.?)

Re:Crocicreas aff dolosellum
Dear Zotto
I am going to ask friends to make sure what is the exact vegetation in Lizara's refuge (Huesca) to confirm the presence of Fraxinus. Any case, this species was found under clumps of small boxs, semi creeper, no farther than 2-3 cm from Typhula buxi and Marasmius buxi (both growing in sheets).
Sorry, it is from 12 Oct. 2010.

Re:Crocicreas aff dolosellum
Fraxinus petioles are easy to identify: They are about 10 cm or so long and one can see the projecting nipples where the pairs of leaflets were inserted. Buxus leaves I know very small and with a short petiole, so my impression is that this is impossible.

Re:Crocicreas aff dolosellum
No, no, Zotto, sorry, I am sure that the substrate is not buxus petioles, too. I am agree with you, buxus petioles are very short. I am thinking more about small branches or twigs of boj (see attached photo of Typhula buxi, please).
For now, two colleagues who visit this area frequently do not remember any fraxinus there, but I am expecting at least the answer of one person from Jaca.
Thank you

Re:Crocicreas aff dolosellum
Oh yes, I forgot that you wrote about twigs. However, your images show me that these "twigs" are flattened on one side, and the upper one shows on the left a broadening characteristic of the basal insertion of the petiole. If you have a photo of the complete substrate I could be more sure.

Re:Crocicreas aff dolosellum
Dear Zotto
99% there are not any fraxinus near Refugio de Lizara. Yesterday we were looking this 1-1,2 mm diameter small branches and someone suggested it looks like "retama".
I have take these 3 photos. I am going to send your private in large resolution.
Thank you again for your help,

Re:Crocicreas aff dolosellum
Ok, Zotto, thank you
I believe it's difficult to make progress with the data we have, because there are not Acer, Sorbus or any other broad-leaved trees near that place, only Buxus, a few Pinus, small Juniperus and herbaceous vegetation. I think we will wait the snow thaw and a local gone close there and confirm us what the vegetation is. ;)
Anyway, Cyathicula aff. fraxinophila. Is it host-exclusive?

Re:Crocicreas aff dolosellum
That's it: I know it only from Fraxinus, over 30 collections. And since the substrate looks 99% like Fraxinus I believe in it.

Re : Crocicreas aff dolosellum
Dear Zotto
YOU ARE GREAT. Do you remember this discussion 5 months ago about Cyathicula fraxinophila / dolosella?
Yesterday Jorge Hernanz were there, at "Refugio de Lizara", exactly in the place we collected the sample, and the place have many, many Fraxinus, perhaps excelsior.
So, Cyathicula faxinophila.
Thanks a lot, Zotto.
