About the size of a pin head. Photographed with a 1:1 macro lens then croped. I will add spore photos shortly. John

Hi John,
looks like Lasiosphaeria ovina.

Re : on fallen wood
Sounds good. I have only ever found it when it was more white colored before. I just put it in a moist box so hopefully it will mature. Thank you.

Re : on fallen wood
In a damp chamber you could also be lucky that it develops its parasite: Krieglsteinera lasiosphaeriae. Surface with erect glassy hairs with a little slimy blob on top. Rather common but easily overlooked fungus. You will find images e.g. on Mycokey.com.

Re : on fallen wood
This is Lasiosphaeria (Cercophora) lanuginosa, a common species. The tomentum of Lasiosphaeria ovina is never yellowish in color. I've found Krieglsteinera lasiosphaeriae on L. ovina before, but never looked for it on L. lanuginosa.

Re : on fallen wood
is it typical with the yellow concentrated near the ostiole? And where is lanuginosa common (and ovina?)

Re : on fallen wood
I only see specimens that are pale yellowish all over, not just at the ostiole.
Both species are common in temperate North America and extend down to tropical Central America. I've also found both in Europe.
Thomas, don't you read my papers every night? ;o)

Re : on fallen wood
But the picture seems to show an almost white tomentum with citrine creeping in near the ostiole. I, of course, use your operas as a sleeping pillow (Andy) :-)
cheers
Thomas
PS would be interesting to get the parasite here as well
PPS how far north in Europe have you recorded lanuginosa?

Re : on fallen wood
yes, as a species complex. We have stuff on grass (4-5 collections) that would fit but Andy has claimed it to be an undescribed species so we have not listed lanuginsoa as Danish :-) (but nothing on wood)
Andrew N. Miller,

Re : on fallen wood
I have about 12 specimens from around the world, all on wood (except one on grass from Denmark), sequenced for 3 genes that fall into the L. lanuginosa species complex morphologically. These are not monphyletic and I have not confidently matched one of them morphologically to the holotype so the "real" L. lanuginosa is still ambiguous. I probably need to collect from the type locality in France and then epitypify this species.

Re : on fallen wood
Hi all,
You have a discussion about this fungus while we have no information about ascospores, asci and all microscopical features.
I would be more careful to give a name.
Goodnight, I'm about to read Andy's thesis before sleeping :)

Re : on fallen wood
Alain, I cannot imagine what else would have a yellowish tomentum, yellow centrum, long, cylindrical ascospores, and occur on wood in temperate regions. Of course, I worked on this species for my Ph.D. and can identify it from 100 meters away... ;o)
Seriously though, most Cercophora's are identified by the characters of the ascomata and look more or less similar inside (similar ascospores, paraphyses, etc.).
You will sleep well after just reading my abstract!
