The case is that following the key Raitvir leads me to H. ocellata.
To see what you think about:
Apothecia white (is kept in after time) slightly stalked up to 1 mm in diameter
Buen año. Os presento este especimen hallado sobre cono caido joven de P. halepensis. Podría encajar con Psilocistella conincola (Hamatocanthoscypha conincola, no se si sería válido) aunque Raitvir piensa que es una forma extrema de H. laricionis??
El caso es que siguiendo la clave de Raitvir, me lleva a H. ocellata.
A ver que os parece a vosotros:
Apotecios blancos (se mantinen tras tiempo) ligeramente estipitados de hasta 1 mm de diámetro

De gran dificultad
Asci cylindrical clavate, biseriate, 8 spores, apical pore blue croziers of 38-45 x 3.5-4.5 microns. Fusoid elliptical asymmetric ascospores smooth, hyaline. with 2 guttae in spore ends, 5-8 x 2-2.5 microns. Paraphyses filiform, uniforms, and some branched straight. Hairs with shapes, some straight and some with ripple-shaped apical rod, thin-walled, hyaline, with basal septum, showing vacuolar inclusions and other surface smooth and finely some rough or small scale, up to 40 x 2 microns in size . Ectal Excípulo prismatic structure with presence of hyaline cells randomly

Hi Javier
if your apothecia atr white I would identify hamatocanthoscypha laricionis. This may grow together with yellow H. uncipila, at least I think the two are different species. Some hairs may almost be straight but are typically strongly uncinate.

Re:Hamatocanthoscypha/Psilocistella
According Raitvir key:
9. Spores with prominent polar guttules.... H. ocellata
9'. Spores without inclusions.....................H. laricionis.
The specimen submitted has guttules in spore ends.
What is the difference between the 3 species conincola, laricionis and ocellata? and especially among laricionis and conincola ....

Re:Hamatocanthoscypha/Psilocistella
I do actually not see clear with this species concept. Stip once identifid H. ocellata, but I do not see the differences. In earlier times, especially when not using oil immersion, I also noted eguttulate spores, but later, I mostly saw some small guttules.
Here I give some collections (left by Martin, right below by Piotr). I think this is all laricionis.
Intetresting is that the paraphyses were sometimes guttulate (?VBs) but usually not.

Re:Hamatocanthoscypha/Psilocistella
I think that fits specimen contributed by Martin and Piotr, another thing is how to call it?
Thank you very much for the information and views presented.
I will continue to provide specimens for your opinions

Hi Javier,
just for my curiosity...
Did you observe something like that with your apothecia as shown in the picture below? Those small white "manitas"...
Best regards,
Martin

Hi Martin,
Although I can not see you picture, in the cone of Pinus were only apart from the specimen submitted, these I bring, some initially thought H. uncipila, which proved to be an anamorph. The other I have yet to watch.

Re:Hamatocanthoscypha/Psilocistella
The picture I see, but can not see clearly either the "manitas"(manos pequeñas en español). It is a structure familiar to me that I could relate to a Myxomycetes?

Dear Javier,
thank you for your reply! So I missunderstood you. Do you really think it's a myxo? I missed the chance to look at those structures microsopically..

Re:Hamatocanthoscypha/Psilocistella
It's like a Ceratomyxa fruticulosa, but ungrouped (but do not think it is). I hope to remember this if I see it.
