Ciboria?
Malcolm Greaves, 22-05-2013 13:16
Malcolm  GreavesI visited a bogland area and found Scutellinia everywhere. Growing on rotting wood,  fern debris, moss and even dung but when the spore size, shape and ornamentation turned out to be identical along with the same hair size and rooting giving me S critina/scutallata? I was dissapointed.
I then spotted this small Ciboria? amongst the moss on one specimen of Scutallinia.
Aproximaately 1.5mm across it tested my microscopic ability and equipment.
It turned out to have a small sclerota or possibly seed at the base. Spores were 8.5 - 9.5 X   2.8 - 3.8 and the ascii had a slight reaction to Meltzers.

The best I can come up with is Ciboria betulae.
Any suggestions welcome.
Thanks

Re : Ciboria?
Certainly not C. betulae which has larger, fusoid, warted spores.

It looks like a sclerotium for me, maybe a Ciborinia? You could try a section of the sclerotium. if it is still hard. If it contains spiral  thickenings of plant tissue then it should be a Ciborinia.

Re : Ciboria?
Thanks Zotto
The sclerotia was round with an indentation in the middle, "doughnut" shaped which didn't show well on the photo. When I cut it in half it had an outer "shell" but very little left inside.
With this round sclerota and no hairs to be seen C candolleana look possible.

Re : Ciboria?
yes, may be. With an empty sclerotium it is difficult.
