Asci 110-120 x 11-12, IKI- (however, with a few years old lugol)

Re : Pragmopora?

I wonder if it is Gorgoniceps. could you do a closeup of the excipulum from outside?

Re : Pragmopora?

Hi Zotto,

Here is an attempt.

Best regards

Re : Pragmopora?

Hi Karl and Zotto,

this is the "Ionopatella multiseptata"

Here in Zottos drive: https://drive.google.com/drive/folders/1HUFyEC64J54uhZqausrutFTxczTiJAfU?usp=drive_link

The brownish exudate should be strongly ionomidotic.

Karl, we have an article in prep, it would be nice to add this find. Can I ask you for collection data? And if it will be placed in a herbarium, also a number of the collection. Thank you,

Adam

Re : Pragmopora?

Hi Adam!

Interesting! Thanks for the ID.
Yes there is a strong purple reaction with KOH if that is what Ionomidotic means.

Here are collection data:
Collector: Soler Kinnerbäck, Karl
Collector no.: FA-24-017
Date: 2024 03 24
Country: Sweden
Province: Närke
Parish: Hidinge
Locality: Svartkärrs nature reserve
Habitat: Temperate deciduous forest, on wood on dead, standing Quercus robur
Coordinates: latDD 59.23783; longDD 14.92991

Here is the sighting in the swedish observations database:
https://www.artportalen.se/Sighting/115378908

I only have a few ascomata but will try and deposit to a herbarium, in that case I will get back to you with the catalougue number.

Best regards
Karl

Re : Pragmopora?

Woww, I did not consider this. And I saw the curved paraphyses. Now I got an idea: this must be "Claussenomyces" tympanoides of which long ago I had studied the type, and a later synonym is C. pusiluus, the type of which Luis has studied. I will move this species now from Tympanidaceae to Cordieritidaceae.

Adam Polhorský, 24-03-2024 17:58

Re : Pragmopora?

Super! Thanks Karl
Ha, I looked in the past at Cl. tympanoides and also at your folder Zotto but I did not make the connection. It really seems to be this species. I can look at it in more detail later. Luis did not try sequencing? It was probably too old.

Hans-Otto Baral, 24-03-2024 18:03

Re : Pragmopora?

I am sure he nows the species only from this old material and did not try DNA. I hope we will get a seuqence of my specimen which is intermediate between the two with 1-septate spores. The lab in MS will perhaps continue in June.
