Lasiobelonium on Artemisia
Marja Pennanen, 07-06-2011 10:45
Hello,

forum is looking new and fresh! Concratulations Christian!

I found some strange looking Lasiobeloniums on Artemisia vulgaris.
They look a little like L. nidulus on Filipendula, but the colour is not as red.
These are about 0,5-1 mm wide.

They have hairs (except colour), paraphyses and asci like L, nidulus, but spores are longer.
Hairs: 40-150x5-10 (-12), may be swollen at tips and lighter at tips.
Asci: 40-50x4-5.
Paraphyses: lanceolate 3-5 micrometers wide and 15-20 exceeding the asci.
Spore:s (8-) 10-14x1,5-2.

Can this be Lasiobelonium nidulus var hystricula?
Let's see, could I even use this new looking forum right, tried to add all photos to same message...

Ps. I changed the led light of my Old Russian to a led spot light with a transformer. So hopefully the light will keep steady as long as the light shows.

Re : Lasiobelonium on Artemisia
That's Trichopezizella nidulus s.l., a difficult group. You can try seeing the croziers if they are present. Spore size clearly excludes T. nidulus which is restricted to Polygonatum and always without croziers. I use the name "Dasyscyphus" rubroguttatus for these long-spored finds, but I learned in England that these are not always with croziers.

Re : Lasiobelonium on Artemisia
Hi Zotto,

thak you and sorry, that I haven't anawered. The new version made me a practical joke. I didn't put the aswer e-mail on and didn't know of anwers...

Now I don't really know, where the specimen is. It may have got ruined in my fridge or is somewhere in the piles of dry or drying specimens, that I have had no time to pack. I've  got grazy overcollecting now, that it has been raining. Last summer was so dry here.

I should and see, weather I find these from the collecting place. I like my specimens fresh. Now it is raining again for some days, so maybe later.
