White hairy on Angelica
Stefan Jakobsson, 04-05-2021 23:47
The worst frost nights are now over here in southern Finland (since 48 hours) so more and more fungi are showing up. Here a very young white disco growing on a last year's stem of Angelica ?sylvestris. The diameter of the apos is about 350 µm and the hairs above 200 µm. I observed just a few ejected spores measuring on average 8,5 x 1,6 µm but I am trying to get more.

In the mean time I'd be happy for ideas on what it could be.

Re : White hairy on Angelica
Trichopeziza mollissima I think.

Re : White hairy on Angelica
Yes, thank you. Now when it has grown bigger it is definitely T. mollissima.

However, on the same culm there is now also another species with more yellowish hairs even if not as bright yellow as the one I have interpreted to be T. limonipilosa. The spores are 10.4 - 15.0 × 1.9 - 2.3 µm, with virtually no visible spore content. IKI faintly bluish, no croziers. Would this be T. sulphureopilosa?

Re : White hairy on Angelica
Hi
These two species are very often found together.
If these are two separate species? As far as I know, work on them has not yet been completed. Zotto knows much more on this subject.
I am wondering, however, a blue reaction to iodine?
Such occurs after pre-treatment of asci in KOH.
Are you sure she was blue?
greetings

Re : White hairy on Angelica
I have not tried with KOH pretretment. But when adding Lugol to a water mount the colour is dirty bluish.

Re : White hairy on Angelica
Hi Stefan

I only asked out of curiosity.
Porus Reaction T. mollissima and T. sulphureopilosa should be red.
Maybe this species is more complex than we think?
Or maybe you have a different genre?

Re : White hairy on Angelica
I remember a RB reaction in this group. Blue at low IKI concentration, dirty red at high.

After KOH there is only blue, of course (definition of hemiamyloidity).
Mirek Gryc, 17-05-2021 18:36
Re : White hairy on Angelica
Hi Zotto
So do you think Stefan used IKI in a low concentration?
Using after Lugol, KOH with low concentration, I also obtained a blue reaction.
How I will find fresh ascomata, I will check more closely.
Thank you Zotto.

Re : White hairy on Angelica
Every hemiamyloid nreaction is blue whenever the fungus was KOH-pretreated. Then there is no chance to distinguish it from euamyloid reactions.

A low concentration of Lugol is a frequent case, yes i assume.
