Scutellinia (?) ... with light hair.
Mirek Gryc, 25-06-2021 11:04
Hello

One more collection sent by a colleague.
I do not have any idea, looks like Scutellinia? However, I have never seen this genre with such a clear hair.
Maybe some suggestions?
In principle, all the most important features are presented in the pictures.
Spores: Me = 17.6 × 17.1 um; QE = 1 (with ornamentation)
Hair up to 400 um long
Ascomata: 3-5 mm in diameter.
greetings
Mirek

Re : Scutellinia (?) ... with light hair.

Hi Mirek,


To me, the spores are suggestive of Scutellinia trechispora which I come across quite frequently on damp, calcareous soil. However, the pale hairs are strange and my trechispora specimens are usually larger and with longer hairs.


Best wishes,


Charles.

Re : Scutellinia (?) ... with light hair.
Hi Charles
I support completely the opinion when it comes to spores, typical for S. Trechispora. I had the pleasure of examining this species.

Other features are not compatible with this species. That's why I decided to post it on the forum.

Thank you for your opinion, at least two of us who think the same :)

However, I do not believe that this species can be so variable? I have examined a few fruiters, all have identical features. Their hair does not match this most.

I was hoping that someone already met with such ascomata.

Have a nice day.

Re : Scutellinia (?) ... with light hair.

Hi again Mirek,


I've come across considerable variability both within Fb size and hair length but I've never seen it with such pale hairs. It looks like there might be an association with moss/algae from your pictures while I mostly find trechispora on bare soil.


Charles.

Re : Scutellinia (?) ... with light hair.
Hi Mirek,
your colleague should try to get a spore print and then compare it with Ramsbottomia.
Cheers,
Marcel

Re : Scutellinia (?) ... with light hair.
I cannot add much other than to totally agree with you both. I see S trechispora quite often but with much longer and darker hairs. The spores although slightly small are a good fit and I don't know of any other species with these truncated spines.
I look forward to seeing other opinions.

Re : Scutellinia (?) ... with light hair.
Hello everyone and thank you for comments!

@Marcel:

Do you know the Ramsbottomia species with such hair?

I was wondering about Ramsbottomia but I did not find any similar. In addition, Ramsbottomia spores have sharp spikes?

@Charles

From what I know, ascomata grown on a layer of rotting leaves of Quercus.

I just got a message from my friend, gathered fresh Ascomata.

If someone is interested in examining this collection, we will gladly send a few Ascomata.

greetings

Re : Scutellinia (?) ... with light hair.
@ Malcolm
Spores actually slightly smaller but Ascomata was not perfect. Too small percentage of ASCI was mature to recognize Ascomata for mature.
To perform the measurement, I chose spores that were devoid of gel sheath and spikes were clearly visible.
Thank you
