Cistella on pteridium
Marja Pennanen,

these nearly 1mm wide cups grow on Pteridium aquilinum old stems.
The spores are 10-14x2-3 and have some big droplets and some smaller, too.
The asci are about 45-60x5-6.
Paraphyses are about 2-3 wide and may have septum and droplets. Their upper part can look nearly glaasy.
The hairs are about 15-30x 3-5, spiny at the upper part.
Cistella artica is close. Can they be this big?

Re : Cistella on pteridium
VBs in paraphyses ar unusual in Cistella, but not impossible.
Asci are 8-spored?

Re : Cistella on pteridium
Hi Zotto,
I tried to count them inside the asci, but am not sure. I thought that I saw at least 5 (meaning 8) in one of them, but can't be sure, maybe only 4. You know the poor condition of my equipment and my eyes are as old as I am ;)
There are some in the fridge. maybe I'll make an extra preparate.

Dear Zotto,
This is naturally 8 spored. I was confused with the Hyalopeziza where I had difficulties while counting the spores.
There may be at least 2-3 septas in paraphyses.
These grow guide sparse at the stems.

Re : Cistella on pteridium
Psilachnum pteridigenum seems to be similar but is said to have smooth hairs.
I was thinking of Phialina anomala, but again this has no warted hairs.

Hi,
I forgot to tell, that I found a couple of fruitbodies on Rubus idaeus stems , too.
They grow only 100 meters away from the place, where I found these.
Many species are shared with ferns and herbs for instance Lachnum virgineum and Cyathicula cyathoidea. I have found some Hymenoscyphuslike growing on Pteridium, too.
