Hi there,
these beauties are about 0,2-0,3 mm wide.
The spores are about 6-8x2, asci 27-34x5-6, possibly IKI+.
Paraphyses are narrow (1.5) and do not exceed asci.
The hairs are yellow, cylindric, 30-40x3-4 and seems to carry some resins.
They tend to be sticked together.
With no knowledge of what this is: Marja

Re : Roses carry beauty
Hi,
this seems common at least on my own yard on old rose leaves.
They turn brownish when dry.
I studied another and the hairs can be up to 80 micrometers long.
I do not find even a proper genus for this.

Re : Roses carry beauty
Hi,
after getting no answers here, I sent a fresh specimen to Seppo.
He is now cultivating this and told me, that this is something near Microscypha / Pyrenopeziza / Psilocistella.
Seems very interesting or what?

Re : Roses carry beauty
Hi Marja,
I wouldn't be surprised if this was somewhere related to Pyrenopeziza or allied genera - the small very asci do suggest a possible link, but the same could be said for other genera as well. I'm not familiar with any Pyrenopeziza species with resinous hairs. Your images did look vaguely reminiscent of something like Pyrenopeziza betulicola.
Yes, I think they're lovely! Â It would be very interesting if they're something new or very obscure, especially since you say they are common in your locality.
Cheers,
Brian

Re : Roses carry beauty
Hi Brian,
I studied another place 15 km away looking for these.
None was found, because there were practicly no last year leaves left.
In my own yard the leaves are mixed with Betula leaves and they may have retained Rose leaves. Maybe it is not common after all, because people have a tendency to clean dead material from their garden. I leave a lot in situ for substrates to fungi.

Re : Roses carry beauty
Hello again,
now I have collected this beautyful species many times from two different places and done some microscoping work, too. Finding old leaves of one specific Rose species is more difficult than finding these on them at the beginning of the summer.
In spite of Seppos opinion, I've come to the conclusion, that this must be an Echinula species and so belong to Hyaloscyphaceae. I still am ready to change my opinion, if better ideas appear ;)
The hairs are resinous an are glued together in the margins, 30-110x3-5. and the asci are IKI blue.
