Urceolella on grasses
Marja Pennanen, 11-09-2015 15:52
Hello forum,

these stipate, hairy ones are about 0,2-0,3 mm wide and a bit taller.
The spores are about 6-8x2-3 and asci 25-35x4-5, faintly IKI blue.
The hairs are glassy, strongly bent at the base. up to 180x3-6 and vanish with KOH.

So this is Urceolella and U. crispula seems to fit. But Raitviir tells, that it should be sessile and this looks more like stipate Olla millepunctata than normal U. crispula.
Has someone here experience of stipate U. crispulas or is this something else?

Marja

Hi Marja,
by our finding U. crispula can be already a little bit stipitate.
Greetings Peter.

Re : Urceolella on grasses
Hi Peter,

thank you.
Your photo seems to be from another world than mine ;)

I noticed some more U. crispula like, short stipate ones on another grass, that I had collected, so maybe the ones I studied were still young. I have found it on grasses (and many herbs) ealier, but these seemed so different.  This is one of those species, that can be found here all around the snowless season.
