Podospora pyriformis?
Joop van der Lee, 08-12-2014 21:44
Joop van der LeeFound on cow dung.
Asci: 8-spored; quickly expand in water 440-616x39-105 um.
Spores: Uniseriate soon becoming biseriate; pedicel curved 45.5-49x8-9 um, transversly septated; upper cauda covering germ pore; secondary cauda attached to distel end of pedicel; spores oval, 40-44x25-26.5 um.
Instead of an upper cauda something else was connected at the sporehead inside the ascus that I do not know (photo-8)

Dear Joop,

Photo 8: IMHO the ascospore is germinating.

Re : Podospora pyriformis?
Hi Joop, how're you? Fine?
Well, your Podospora is like P. pyriformes in some aspects, mainly in the atypical septate spore. But P. pyriformis, the upper cauda not cover the germ pore. You're right? Cuz the septate spore is very common on this kind... You have pics of the ascus type? According Bell (1983) this specie grow on old dung. It's your case? I bet on this :)
Can you send more details? 
With my best regards,
Francisco Calaça.
