Hi does anyone have a digital copy of Raitviir A (
This is yet another Podospora which has developed on a collection of rabbit dung (along with P. (Schizothecium) tetraspora, P. fimiseda and P. pleiospora).It seems to sit uncomfortably between P. setosa and P. curvicolla.
For the former are characters like the shape of the asci (clavate, not saccate), no asci with 256 spores and the gelatinous appendages which are persistent on the mature spores and do not disappear in water mounts.
But the spores seem small for P. setosa and would fit better in P. curvicolla - they measure 16.4-17.3 x 10.4-11.7µm; also in some cases the hairs could be considered 'agglutinated'. I know there are ASCOFrance members with lots of experience of these coprophiles, and would again be grateful for assistance.
Cordialement

It is sometimes difficult to separate these two species, but the size of the spores and "agglutined" hairs closer to curvicolla.
It is important to measure a large number of spores to have a mean, especially since it is sometimes difficult to count the number of spores within the ascus. I also picked up some copies of P.curvicolla with little hairs "agglutined".
Michel.
