Perithecia on Horse Dung
Malcolm Greaves,

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.

Re : Perithecia on Horse Dung
Thanks David
Looking at your suggestions and papers provided by Chris Yeates (thanks again Chris) the conidia look to be close to Dactylella probably heptameres.
Mal
No other cleistothecia have developed
