Perithecia on Horse Dung

This perethecia c.25mm was on horse dung. The only "spores" that I could find were these elongated septate and tapering ones 43 um long. The could be contamination from outside but if not they are fairly distinctive.

Can anyone help.

Thanks

Re : Perithecia on Horse Dung
Hello Malcolm,

The perithecia (or cleistothecia) are probably not related to the two spores in your last photo. These are conidia of one of the nematode-trapping hyphomycetes, probably either Candelabrella or Monacrosporium. Both are now known to be anamorphs of Orbiliaceae.

No other cleistothecia have developed
