Are you sure that hairs cannot exceed 800 µm in length? After your macropictures, some of them seem to be very long...
Scutellinia crinita could be a good candidate.

hi klaas,

i agree to nicolas - some hairs on the left picture are definetely longer than 800! are you sure you have one species? the apos on the right picture show much more dense and regular hairs (in length) than the sparse crinita-like one on the left!
also the ornamentation seems to show diferent states of wart-isolation ... difficult.

schöne grüße

dirk

amateur-documentation is a nice understatement ;-)

Dear Nicolas and Dirk,

thanks for your answers!

@ Nicolas
I am definitely not sure that all hairs did not exceed 800 µm, but the ones i measured at the edge of the cups did not...

@ Dirk
The apos on the right picture were very jung and small, maybe thats why the hairs seem to be different?
Otherwise, a different species could be a good idea, i am therefore just as undecided as with the hair - that's what i mean with „amateur" ... ;)

Scutellinia crinita seems to be the best candidate for my collection (or at least a part of it), but i cannot reach it in the keys. I try it backwards with my german Schumacher key:

37b) Ascosporen 16,6 - 21,2 x 11,1 - 13,8 µm:
S. crinita (Bull.: Fr.) Lamb.

-> my collection: 19–21(22)x(12)13–14(15) ?m - seems to be o.k.

35b) Ascosporen deutlich skulpturiert mit Warzen und gewundenen Graten 0,2 - 0,8 µm breit,
bei einer Höhe von 0, - 0,6 µm, Ascosporen mit abgerundeten Enden ............................ 37
-> my collection: o.k.

34b) Ascosporenskulptur im Lichtmikroskop klar erkennbar .................................... 35

-> my collection: i don't know wether that means „clearly recognizable" in water or in colorant -
if in colorant „o.k.", if in water: „not o.k."

29b) Ascosporen Skulptur mit Warzen und Graten 0,2 - 1,4 µm breit und bis 1,3 µm hoch ....... 34
-> my collection: warts small < 0,5 ?m, o.k.

28b) Ascosporen ellipsoid bis breit ellipsoid, weniger als 27,5 µm lang ..................... 29
-> my collection: o.k.

27a) Apothecien mit an der Basis mehrfach gegabelten Haaren, einige Haare über 1000 µm lang ......................................................................................... 28
-> my collection: i cannot exclude Hairs > 800 µm, maybe o.k.

21b) Ascosporen, deren Wand sich beim Erwärmen in Baumwollblau nicht ablöst, Randhaare
gerade, in der Länge zwischen 200 - 3000 (!) µm ...................................................... 27
-> my collection: o.k.

--------
addition:
Point 10 / 16 are the parts of the key i have alway problems with, is there a mesh or warts?
------- 

16b) Ascosporenwand mit deutlich verbundenen Warzen und/oder mit Rippen ..................... 21
16a) Ascosporenwand mit gerundeten, isolierten Warzen (Knollen) ............................. 17
10a) Ascosporen mit vollständigem oder unvollständigem Netz ................................. 11
10b) Ascosporen mit Warzen, die zu kurzen Graten verbunden sind oder nicht .................. 16

Backwards it works with some smaller doubt, but without a species in mind, i often miss a target
while following the keys in the right direction, and i dont know why.
I'll try the other keys backwards an i hope you are not too bored with my long "work"...

I forgot to mention that in a German forum there was also a hint to S. crinita, but i had doubts because i had not shown all the characteristics as i did it here. However, it seems that the species is really S. crinita.

Many thanks and best regards
Klaas

Hi Klaas,

not that I could help you much with the Scutellinia problem but are you sure that those small, brownish apothecia on the last macro photo of plate 1/5 belong to S. crucipila (as indicated by the arrows)? To me it looks more like a Tricharina or something similar. But I might be wrong of course so sorry if I caused any erroneous confusion!

Best wishes,
Gernot

Hi Klaas, ich denke, Gernot liegt richtig. Mein Tipp wäre aber eher "Leucoscypha" semi-immersa statt Tricharina.
Beste Grüße
Uwe

Hi Gernot, hi Uwe,

i'm definitely not sure with S. crucipila, but the hairs seemed to be quite similar to this. But the color fits not really good...
The fruitbodies were unripe, < 1mm, only some paraphyses and many hairs.
I will try to attach two pictures, maybe it works.

If i compare with my own findings of Leucoscypha/Pustularia, there is different base at the hairs, or am i wrong?

Maybe this was L. semi-immersa, it was too long ago, so i can't verify it anymore:

Another finding of a Leucoscypha/Pustularia to compare the hairs:
http://taunuspilz.de/coppermine/albums/ftp_ul/2013_11_17/2013_11_17_Pustularia_patavina-3.jpg

For me they seem quite different, or?
But i can't proof it, the fruitbodies don't live anymore, so i'll remove the arrows or replace them with an interrogation mark in my final version.

I'm really uncertain with fungi...

Thanks a lot and best regards
Klaas
