Re : Stictis sps on wood
Hi Tony
I think your species is close to the "P3971" species on the FGBI website; the difference in ascospore cell size may just be variation in the number of times the cells divide after formation. It also appears to have a yellowish exciple rather than the pure white one for P3971.
However, your post prompted me to revisit the identification, and I now think that it is a species of Schizoxylon. The genus was traditionally separated from Stictis by the ascospores fragmenting into part-spores, as well as differences in the periphysoids, but not all species have spores that fragment. S. berkeleyanum also has a K+ yellow reaction and usually a pale yellow exciple, but has fragmenting ascospores - but this could be a factor of maturity. For the moment I will leave "my" species as indetermined [actually collected by Pauline Penna so arguably hers rather than mine!], but yours might well be berkeleyanum. If you have spare material I'd be happy to look at it...
The species on FGBI can now be found here - http://fungi.myspecies.info/all-fungi/schizoxylon-sp-p3971

Re : Stictis sps on wood
Hi Paul,
Glad you saw this, and excited to see that this has a possibility of being a Schizoxylon sps. I do have a few specimens left, so will send these to you as I should know your address! The asci and spores look very close to your measurements on your site. I also had occasional partially coiled spores.
Many thanks Tony
