Yellow Lachnum

I've seen this yellow hairy one for three years on grasses in the same small damp place on a field.
They are about 1 mm high and the cup is up to 0,5 mm wide.
The yellow colour comes from paraphyses and hairs.
This seems to be a combination of L. tenuissimum and L. carneolum var. longisporum.
Spores: 10-15x1,5-2.
Asci: about 30-60x4.
Paraphyses: lanceolate, yellow , up to 6 wide, about 20 exceeding the asci.
Hairs: 40-50x4-6, swollen at tips, yellow based.
Once again help is needed, because none of my sources has a description of anything like this...

Re : Yellow Lachnum
Hi Marja
I wonder whether the spores are really that long. L. carneolum has non-capitate hairs, and I do not know it with yellow VBs. L. tenuissimum (I use the name pudicellum) may have yellow VBs, and I think this is only a colour variant.

Re : Yellow Lachnum
Hi,
I contacted Marketa and she told me, that this could be not so often collected Dasyscyphus winteri (Cooke) Svr?ek.
No wonder I (and maybe Zotto, too) had severe difficulties with the determination...

Re : Yellow Lachnum
Lachnum winteri (Cooke) Velen. is a species perhaps confined to Phragmites and, like L. controversum and L. tenuissimum/pudicellum, without croziers (in case you see that). But L. winteri and L. controversum have apically hardly inflated hairs, whereas L. tenuissimum/pudic. have capiate hairs. I think yours look much too capitate for L. winteri.

Re : Yellow Lachnum
Thank you.
I should once again go and check weather I can still find this. The midsummer fest is approaching and I'm going to our county place. I'll go hunting this, if the insicts let me. If it has vanished then next spring or early summer. I have only a scanty specimen.
This grew together with a bigger Lachnum, L. carneolum var. longisporum?, if I remember correct. I checked, but made no notes, because I have studied that so many times before.
You know, that croziers are a bit too hard for me, but I won't still give up: Marja

Re : Yellow Lachnum
I remembered collecting this more and now finally found some from my boxes.
I studied it for croziers and think I saw one, but the asci bases do not support that.
I measured many spore lenghts in 1000x and they are really 7-15Â (9,10,13,12,13,8,7,11,15,14,12...). They seem too long for L. tenuissimum.
All the hairs are not capitate and they may be a little over 50 long.
