Sebastien BassoHello, I'm conducting a mycological inventory in
Good nightThis is from La Gomera (Canary Islands), in a very wet place recently burned, 1.100 m, in "fayal-brezal", semihipogeous, in ash slurry, 4-8 mm, yellow hymenium, beside Peziza.
Hairs from margen to basal zone.
Thank you.
Spores (1000x, H2O)
(12.0) 12.5 - 14.9 (15.1) x (7.2) 7.7 - 9.1 (9.3) µm
Q = (1.5) 1.55 - 1.7 (1.9) ; N = 33
Me = 13.8 x 8.4 µm ; Qe = 1.7
Thank you and sweet dreams.
I don't remember where but I have read that all of Wilcoxina species are always mycorrhizic with conifer trees. Hosts of Wilcoxina mikolae are Pinus and Picea in general.
And Tricharina praecox seems to grow in burnt place and a part of apothecia are driven in the soil. Like your collection...
Are Pinaceae trees present in your habitat ?
In the past, I have known the same problem but I don't refind my data.
I will try to search again and keep you in the loop.
Moreover and as you know, I'm very not a specialist of these genus...
Amically (and un saludo to Fermin)

I am not the collector, Rubén Negrín is. I am going to ask him, but "a priori" the habitat is fayal-brezal (Erica arborea, Myrica faya, Laurus novocanariensis ...), but sometimes there are some Pinus canariensis or P. radiata mixed.
Amically.
do you tested with cotton blue whether the spores have an ornamentation or not?
The spores of T. praecox var. praecox and of T. praecox var. cretea have a finely warted perispor.
For T. praecox var. praecox look here: https://www.sites.google.com/site/funghiparadise/ascomycota/pezizales/pyronemataceae/tricharina-praecox-var-praecox-p-karst-dennis-1971
Best, Uwe
No, I did not check it. I have dried material, perhaps tomorrow.
Is not the hymenium very yellow for T. praecox?
Hi Beñat
Rubén said no Piceae, only mud of ash from last year La Gomera fire in fayal-brezal. Perhaps Piceae above, but burned, not in a good condition to mycorrhizical process.
Thanks.
the yellow color is no problem. The hymenium of T. praecox can be yellow or brown. Sometimes it has also a orange tinge. The hairs can be hyalin or light brown. T. praecox is macroscopically a very variable taxon.
Here is a photo of T. praecox with a yellow hymenium, collected by Peter Püwert.
Best, Uwe
I understand with this spore ornamentation this is Tricharina praecox v praecox, isn't it?
Thank you.
