White hairy on Lycopodium
Marja Pennanen, 11-06-2010 14:16
Hello,

I found these yesterday and just couldn't get a proper photo. Maybe because these are quite small, about 0,1 mm wide.

Re:White hairy on Lycopodium
The spores look like canoes and are about 5-7x1-1,5 bearing some droplets.
Asci are 23-27x3,5-5 and paraphyses narrow (1,5).
Hairs are often bent and about 25-40x2,5-3 micrometers.

Re:White hairy on Lycopodium
Peut-être un Psilachnum ? voir si les asques ne sont tétraspores.

Re:White hairy on Lycopodium
Merci.

Psilachnum is a good option ;) Unfortunately I didn't find any quite matchng from Raitviirs descriptions.

Re:White hairy on Lycopodium
With Zotto we have an undescribed Psilachnum on Lycopodium clavatum caracterised by asci tetraspores. The spores are with 4 guttules and 10-14 x 1.5-2 µm.

Re:White hairy on Lycopodium
These can be even 0,5 mm wide.
The microscophy is a little different, but not very much.
Spores are 9-12x1,5-2 and have about 6 droplets.
Asci 25-30x4-6 and paraphyses 2-2,5 micrometers wide and they have often a big droplet near the tip.
Hairs are about 25-50 x1,5-2.


Greetings: Marja

Re:White hairy on Lycopodium
Oui ! Cela ressemble beaucoup à notre espèce (Psilachnum lycopodii ad. int.) ! Les asques sont-ils à 4 spores (avec souvent 4 autres spores avortées).
