Hola tengo estas muestras recogidas en Tamarix.Lo mas cercano que veo es Mollisia rosae, pero esta es de Rosal, no se si saldra en otro sustrato o simplemente estoy equivocado y puede ser una Pyrenopeziza.
La mayor medida es de 0,53 mm.
Excipulo de color marron con celulas globosas a subglobosas.
Ascas con croziers, J-, miden entre 52--56 x 5,5--7.
Esporas 8--12 x 1,8--2,3 con una gota lipidica en cada extremo.
Parafisis X 3--X 3,5, apice redondeado.
Pelos 40--70 X 4, apice mas inflado 5--6,5.
Con KOH los pelos marrones viran a grises

Hello,
this is a Mollisia ss. str (no Pyrenopeziza)., and I think this could be Mollisia ligni.
The spores are a little too long for this species, but the rest would fit.
The ascus porus reaction, is it really negative?
Did you observe the shape of the fruitbodies, when it is slowly drying? Does it become triangular when slowly dehydrating?
best regards,
Andreas
A ver si nos podemos ir acercando

Hola Rafael,
the shape of the ascomata is very typical for Mollisia lignI!
So I would have no probelms to name this M. ligni (non ss. BREITENBACH & KRÄNZLIN!!)
best regards,
Andreas
