Pinkish ones

Hello forum,
I found these tiny ones on old stems of a perennial flower. The stems were guite soft. I actually looked for them, because I had found them last autumn, too, but had no time to study them.
The fruitbodies are about 0,1-0,3 mm wide, first white turning pinkish later.
The spores are multiguttulate, about 9-15x3.
The asci are about 35-55x9-10, IKI+ blue and paraphyses are narrow.
I thought, that this was not hairy, but found some small structures, that may be hairs, about 10-15x3-4.
Curiously: Marja

Re : Pinkish ones
Hello,
were the "hairs" a bit darker, brownish? They remind me on Chalara anamorphs, sometimes occuring on the margin of Calycellina sp. There is C. separabilis on Rubus with similar spore shape and guttulation in Zotto's folder, but I don't know it firsthand.

Re : Pinkish ones
Hi Victorie,
Zottos Calycellina chalarae has more and bigger guttules and bigger septate spores than these. I saw no septas in spores.
The hairs do not seem much darker in my opinion and are almoust invisible on eye or loupe. I suppose, that I found hairs only because one fruitbody went upside down on preparate. They remind a bit Hyaloscypha hairs or do they?
Thank you for your answer: Marja
