Helotial on Juniperus communis twigs
Enrique Rubio, 05-08-2009 19:30
Enrique RubioHi again:
I’d like to know your opinion about this Helotial that forms little, gregarious and sessile ascomata up to 0.5 mm on Juniperus communis twigs (bark and wood).
The hymenium is whitish pruinose, amber color at maturity. Margin downy by obtuse hairs

Hairs in KOH.

Re:Helotial on Juniperus communis twigs
Uff, I don't know that. The hairs are important, they look like having a glassy lateral wall unchanged in KOH. This remins me a bit of Urceolella/Hyalopeziza conspicua/juniperi though there the hairs are much longer, more thick-walled near the tip, and the spores aseptate.

No idea. I would again be happy to see the images in higher resolution.

Re:Helotial on Juniperus communis twigs
I now believe that this is Pseudohelotium sordidulum or a very close relative. Hairs fit very well to HB 5001d on DVD.

Re:Helotial on Juniperus communis twigs
Yes. It seems to be very close! I can read the label Pseudohelotium vernale in your card. It's a synonymous of Ps. sordidulum?
Many thanks again, Zotto.

Yes, in Huhtinen 1994: 6 (Finnish records of discos) it is asynonym of sordiduolum
