Joop van der LeeFound on rabbit dung.
This species has characteristics of Sordaria as well as Coniochaeta but up till now I do not have any clou what it might be.
Fruitbody: Spherical, with a short and broad neck, no hairs foung, body is completely submerged in the dung and only the neck is visible.
Asci: 8-spored; 256.6-274.5X25.5-28.2 um, swelling in width from 43-59 um in water. Apical apparatus showing blue with Melzer; short stalk.
Spores: Uniseriate; very dark brown when mature; mature spores 26-43x16-23 um;
immature spores 26.4-28.8x12-15.9 um; spores are surrounded by a gelatinous sheath; spores have a longitudinal germ slit along the entire length of the spore.

Re : Unknown pyrenomycete
Why not an Hypocopra species?

Re : Unknown pyrenomycete

Thanks for the hint Enrique.
I have also checked the endostratum and stroma cells and they do correspond with the description in Doveri FFI with Hypocopra merdaria but the length of the asci do not.
Also the great variety in spore size is not mentioned and length of germ pore is along the hole spore.


These correspond with H. festucacea.

Re : Unknown pyrenomycete
Hi Joop.

Spores of H.festucacea has two cells; on your photos we see only a single cell, in addition, the stroma is normally colored. Delicate kind,to start, you need to observe from where stroma, if tomenteux or not (as perithecia), and also see if one or more perithecia.

Bonne recherche !

Michel.

Re : Unknown pyrenomycete
Hi all,
Michel surely has with his information. I my opinion the two- celled spores mostly hardly to see, I had collections with 2-cellular spores in a relation "one to one thousand". But the photos show Hypocopra merdaria, I do not know H. festuca.
Greetings Peter.
