Malcolm  GreavesI came across this growing on and around some Podospora on sheep dung and although I think it might be a Hyphomycete and I know that is not the purpose of this forum but has anyone come across anything similar.
The distinctive multi septate spores are up to 90 x 10.5.
Thanks

Re : Non Asco
This looks much like the anamorph of Orbilia fimicoloides, Dactylella oxyspora. Conidial size fits well.

Re : Non Asco
Dear Malcolm,

Could be some species of Dactylella, these are nematophagous fungi and occur often on plant litter or dung.
No idea about the species...

Best wishes,
Mateusz

Blast!
Zotto was faster and much more precise again!;)

Re : Non Asco
And I should add that Dactylella is in fact non-nematophagous, although very closely related to the nematophagous group. This is strange because this species was repeatedly found on dung, though more often on herbaceous stems.

Re : Non Asco
Ah, indeed, I see now that after the revision by Rubner (1996) all nematophagous species were excluded. I remember some older studies, by Drechsler from 1940', and by Cooke and Dickinson (1965), where all those Dactylella and Monacrosporium were treated together.
I have observed them more frequently on strongly decayed plant material with abundant infestation with nematodes and other fauna, and I thougth that was not a coincidence. But indeed I have never seen the very act of capturing the prey, nor I was able to see any adhesive hyphae.

Re : Non Asco
It is right that in earlier times the genera were separated by conidial septation and conidiophore types, bit since the genetic work of Hagedorn and Scholler the trapping organs play the major role.  These organs are indeed not easily discovered. We have seen them occasionally on the natural substrate (constricting rings, adhesive knobs and pegs, but never adhesive nets).

@Malcolm
It should also be said that 'hyphomycetes' and 'coelomycetes' - at least the vast majority of them - are anamorphic Ascomycota, and therefore very much included in "the purpose of this forum" ;-)
kind regards
