No Chris, so will send it dry by post. Sorry for delay, been somewhat busy...................
Ahem, I have lost the e-mail with your address on, so can you let me know again? I'll send you an e-mail to reply to.
I have the bit of wood it's on ready to go, nice and dry, when you contact me.
Thanks a lot
Ken

a drawing might help, if you haven't got a camera attachment yet

OK

specimen arrived (at last!); it is indeed spiny:


the spines are relatively short, averaging around 60µm:


the material is in excellent condition and with mature spores, drying does not affect the micro-characters significantly; so in answer to my questions above the ascospores are hyaline (i.e. colourless) to faintly straw-coloured and becoming septate (multi-celled):




they are also pretty big - 65µm or more long and around 7.5µm wide

with a bit of experience these characters point to the genus Lasiosphaeria (as suggested by Mal above); the shape of "hairs" coupled with multi-septate, relatively broad (for the genus) spores lead to an ID of

Lasiosphaeria hirsuta

if this was in historical Yorkshire, Ken, please PM details; I shall keep the material in my herbarium if that's OK with you?

cheers

thanks for passing on the collection info, Ken - it's a new 10km square for it: NBN Gateway: Lasiosphaeria hirsuta grid map
