Could this be dried fruitbodies of Ascobolus albidus?
Found on horse dung in Uppsala, Sweden. Spores 24-30 x 12-14.
Fruitbodies very small, around 0,2 mm, in large numbers and mostly violet but sometimes like thin, pale "sticks".
Best regards
Karl

Re : Ascobolus albidus?
Hola Karl: Tu recolecta cuadra bien con esta especie. El tamaño esporal y ornamentación son adecuadas para la misma. He encontrado varías veces formas con esas coloraciones marrón-púrpura. Están descritos varios tipos de coloraciones además de la blanca-hialina que es la más frecuente. Ahí te pongo algunas fotos de recolectas de distintas coloraciones, para que compares. Un saludo Augusto Calzada

Hello Karl!
Have you thought, for simple verification, to compare with roseopurpuracens, sometimes these species are close.
Michel.

Re : Ascobolus albidus?
Hello Michel!
I have also thought about A. roseopurpurascens. Some say that it is only found on deer dung. In the keys I have checked the width of the asci seem to be a separating character, but different sources show different information... Do you know any good sources for separating the two?

Re : Ascobolus albidus?
Roseopurpuracens can be found on substrates other than deer droppings. I think the presence of purple pigment in the exipulum and at the top of the paraphyses is a good trait, as well as the well marked margin on the apothecia.
Michel.

Re : Ascobolus albidus?
Thanks!
I will search for more information about the species and compare.
