I think I may have found the teleomorph of Dendros

Joop van der LeeFruitbody is hard to find because the colour of its body is equal to that of the surrounding dung.
I could only find them because of the spore ejeculation that took place.

Fruitbody: lightbrown/orange, 0.36x0.36 mm

Asci: 55.5x26.5 um with a short stipe of 9.0x5.3 um, asci is containing young spores
Asci with almost mature spores 62.8x32.7 um 

Spores: 17.5-19x14-16.5x12.5-13.5 um

Re : Unknown asco on horse dung
Hi Joop.

Your photos are not clear enough to distinguish some of the details, but it seems that there is no stalk or gelatinous appendages on spores. It also looks like some spores have two germ pores, is that correct?

Michel.

Re : Unknown asco on horse dung
That is correct Michel, the spores look like those of a Chaetomium.

Have you thought about the kind Melanospora?

Re : Unknown asco on horse dung
I will check Michel with what I could find it seems that way, do you have any documentation about these species?

Re : Unknown asco on horse dung
More details about the species:
Spores; ellipsoid-citriform with two depressed germ pores, in one position spore shows flattened side when ellipsodial.

Recalculated measurement spores: 19.85-21.25x15-16.5x11.8-12.4um


No beak observed, fruitbody collapsed as soon as it's under the coverglass
Measurements come close to M. brevirostris.

Re : Unknown asco on horse dung
La taille et la forme des spores ressembleraient plus à M.zamiae; as tu pu mesurer la longueur du col ?
