Re : Stictis on Bamboo sps.
Hello Tony
I have material of Stictis stellata on bamboo (from Hampshire), and despite its name the ascomata are usually not noticeably stellate. You probably have either this species or S. arundinacea; the easiest way to tell between the two is to section the fruit-bodies; S. arundinacea has a wall that is at least partially dark, while in S. stellata it is ± hyaline. They both have strongly white-pruinose rims, so don't confuse this with wall tissue.
Best wishes
Paul

Re : Stictis on Bamboo sps.
I can't really tell from these images. Ideally you need to split the bamboo along the grain and then whittle away using a double-sided razor blade (with obvious attention to health and safety) to get thin sections (as thin as possible). You can either mount them in water and observe using your compound microscope, or you might just see a dark line delimiting the fruit-body (if it is there) with the high power of a dissecting microscope.
Enjoy!
Paul

Thanks Paul. I'll try, but if you don't hear from me again then the razor slipped.

Re : Stictis on Bamboo sps.
hi Paul,
Tried my bwest here but doubt it was good enough. Shaved down very gradually and these are the three images I manged to obtain on compund microscope at 40x and 100x last one. Just looks plain whitish to me, but expect not good enough.
Placed the cut along grain slice between two pieces of bluetack! Keep it intack while I skimmed it. I might have learnt something there.
Regards Tony

Re : Stictis on Bamboo sps.
Still not completely sure but S. stellata seems to be a good hypothesis for the ID.
