Hemiamyloid on leaves
Marja Pennanen, 20-10-2010 13:34
Hello,

I found these on my own yard on (Betula) leaves today.
These are about 0,2-0,5 mm wide:

Re:Hemiamyloid on leaves
The spores are 15-18x4-5, with two small droplets.
Asci are 100-130x10-12 and hemiamyloid (IKI red).
Paraphysesa are 2-3 micrometers wide and can branch.

Ascus tips in Lugol.

I found no Calycellina, that fits.

Hi Marja

splendid microphoto! This is an Allophylaria, closely related to Calycellina in my opinion. I think it is A. zenobiae (maybe as Conchatium in Index Fungorum). A. nervicola has shorter spores.

Oil drops in spores are usually some minute near each end, but submature spores have one bigger as you figure.

If you look at the excipulum near stip or near margin the cells should be a bit gelatinized (other Allophylarias have more gel).

Re:Hemiamyloid on leaves
Thank you :)

All information is more than wellcome.

I only know Allophylaria vulgaris, which is very common here now for instance on Betula twigs.
I (almoust) know it from it's appearance and haven't studied it for a long time, maybe it's time for a comparision.

This species maybe once again new to Finland-or maybe not...

Re:Hemiamyloid on leaves
Probably new. But A. vulgaris is not an Allophylaria, it is a Calycina.

I admit the two genera are quite close....

Calycina vulgaris is inamyloid, can you confirm?

Re:Hemiamyloid on leaves
Let's see, if I have a specimen. If I did not collect it, I'll do that later this week.

I've got Lugol only for maybe half a year and haven't used it for this (A. or) C. vulgaris yet.

Re:Hemiamyloid on leaves
Hello,

Zotto you making me doubt everything I thought I knew. Maybe I'll bring all the species here just to be sure ;)
I had some on the twig, where was R. firma, too.
I can't say, that the fungus I thoght originally as A. vulgaris is inamyloid, but I can't say that it's amyloid either. It's not so obvious, maybe it's hemiamyloid...

Just too tired now, I'll go and get some rest: Marja
