This tiny (<0,5 mm) beaty (sorry about photos quality) has yellow, funny hairs ;)
I'll try to figure a way to get photos of microscophy ...

Re:Hamatocanthoscypha straminella
Hi Marja,
I doubt it because all species of Hamatocantoscypha are nearly sessile, this thing has a distinct stipe. To me it looks more like a Hymenoscyphus or Crocicreas/Cyathicula, they somtimes can have free hyphal ends that gives a hairy appearence.
for micro-photos try to get your hands on a digital compact (preferable with a small lens) keep it in front of your oculair and just click.
Cheers Stip

Re:Hamatocanthoscypha straminella
Hi,
I just read the description of Hamatocanthoscypha uncipila from Nordic Macromycetes vol1. It tells, that it is stipate. As far as I know this is very much like H. uncipila, but has bigger spores and grows on deciduous trees.
I tried to take a photo in the microscope. I still think those yellow ones are hairs...

Re:Hamatocanthoscypha straminella
Hi Marja,
The microscopic picture shows i was wrong, the asci and spores do look Hyaloscyphaceaeous, i never saw them so stipitate. The yellow things you are talking about are the refractive Vacuolebodies (VBs) in the paraphyses but they also will appear in the hairs, perhaps the ones in the bottom of your photo. To get a good view at the hairs try to put a fruitbodie upside down on your slide and cover it gentle with your coverglass.
the difference between straminella and uncipila
uncipila is on conifereous wood and has asci Mlz + blue
straminella on decidious trees asci Mlz - if you use Lugol it can be red
Cheers Stip

Re:Hamatocanthoscypha straminella
Dear Marja & Stip
I think it could be a Calycina close to C. discreta. I have distinguished a "pseudodiscreta" with light yellow VBs in the paraphyses and hairs (which are straight). There is also a problem with the croziers which are present in pseudodiscreta and in ?most finds of discreta absent .
In the attach the apos are too white, they were distinctly yellow.
The spores measure about *6-9 x 1.7-2 µm

Re:Hamatocanthoscypha straminella
Hi Stip,
how on earth do you handle these tiny fruitbodies so, that you can put them between the glasses the way you want?
My equipment is poor, no reagants etc. But luckily I have friend in the local university, where I can use them :D

Re:Hamatocanthoscypha straminella
Hi Marja & Zotto
I use a dissecting microscope to do such things, a needle and a lot of patience :-)
Ask your friend at the university for Lugol, it has a wider range of reactions.
I think the pseudodiscreta is something else, the photos show a difference between sporeshape and content.
cheers Stip

Hello Stip and Zotto,
thank you for your information.
And thank you Stip for the hint of trying to take a photo straigth from the scope. It certainly worked ;)

Marja to make your photos sharper, half clich and than adjust your microscope a bit while looking in your camera before you activate the shutter.

Re:Hamatocanthoscypha straminella
The spores are in fact partly longer in relation to their width, but they vary so that also such I can see on Marjas photo occur as you can see here inside the ascus.

Seppo Huhtinen has checked the specimen and confirmed it to be Hamathocanthoscypha straminella.
It's not been very popular- less than ten collections around the world ;)
