Encoelia impudicella?
Hulda Caroline Holte, 25-03-2026 10:35
Hello,
I collected this species growing on a dead branch (broken off a tree) of Picea abies on the 4th of march, in Buskerud county, Norway.
The apothecia are up to 2,5mm wide and 2mm tall. The hymenium has a hazelnut brown color and the outside is slightly lighter. The outer side is granular to felty and often has lighter tufts of short hairs at the margin. The flanks frequently tears in older specimens. The apothecia grows in groups of 2-6 arising from a common structure resembling, but somewhat different from, a sclerotium. The "sclerotia" start off small and black/dark brown before increasing in size and turning lighter brown with a cracked surface. The inside is light brown.

Medulla of textura intricata and possibly with crystals. The hyphae are about 2-4 µm wide.


Asci IKI+ bb, with croziers (possibly a bit variable)
24-29,76 x 3,36-3,84 µm


The paraphyses are cyllindric-clavate, scarcely septate and with some drops. The paraphyses measure up to 3,3µm at the tips.


The spores are thinly allantoid, sometimes with small LBs near the ends. OCI 0/1
(4,8)5,8-6,2 x1-1,5µm


All measurements were taken from living cells in water. The spores were incredibly difficult to measure and photograph due to their small, narrow shape and constant shifting, so the spore measurements might not be 100% accurate. I apologize for the subpar photos and I can try to take more if needed.


The description of Cenangium impudicellum (synonym of E. impudicella) in P. Karst., Bidrag Kännedom Finlands Natur Folk 19: 219 (1871) is the closest match that I have found, but the asci are noted there as being inamyloid. I have struggled to find newer collections of this species to compare my specimen with and I would be grateful for any input.


Thank you in advance and best regards,
Hulda

Re : Encoelia impudicella?
Curious collection! I think E. impudicella is a good choice, but I also know it inamyloid from my study of a specimen on Picea from Luxembourg and from photos by R. Blasco on Pinus.
Hulda Caroline Holte, 25-03-2026 17:15
Re : Encoelia impudicella?
Curious, indeed! Thank you for your reply. 
Do you believe that this species can be variable in its amyloidity and that my specimen is Encoelia impudicella regardless of the reaction? 
E. impudicella has not been recorded in Norway previously, and I have not found any collections of the species from Sweden or Finland (where it was derscribed from) since 1935. Therefore, I would like to be certain before I determine it.
Kind regards, Hulda

Re : Encoelia impudicella?
What is certain and what is not certain? We are rarely sure with the final truth. Variability in the amyloidity occurs, I know several Helotiales which have identical ITS, one sample being IKI deep blue and the other IKI-. I do not know of a sequence of this species. Presumably it belongs in Cenangiaceae, in which both amyloid and inamyloid taxa are frequent.

Re : Encoelia impudicella?
I fully understand what you mean.
Species concepts and delimitation is of course primarily a theoretical construction and changes with our understanding of nature. I know that completely determinate answers in this group of fungi are rare. What I meant to ask was if you, as an expert, would consider my specimen to be close enough to register/note it as E. impudicella (in the current sense of the taxon and with the data that I have given)?
Kind regards, Hulda

Re : Encoelia impudicella?
To answer your question would mean that I go deeper in what is known about this species. Literature often contains errors and you must be careful to believe what is written. Did you compare the protologue? I see Karsten when doing the combination in Encoelia also states the asci to be inamyloid. More reports I do not have at hand. The spores are somewhat larger in Karsten's diagnosis than in yours and mine. Rafael's measurements better fit: 6--8 x 1,5 (10x1;5).

I think we can name all these finds E. impudicella - for the time being.
Hulda Caroline Holte, 26-03-2026 17:08
Re : Encoelia impudicella?
Thank you so much for your answer. I greatly appreciate the effort that you have put into helping me!
I have read the description of E. impudicella in Karsten (1871) which Mycobank gave as the protologue. I have tried to compare it to the best of my abilities. I especially note that the color is said to be grey in young apothecia and later cinnamonish brown. This also fits with my specimen.
Kind regards, Hulda

Hello, 
I would like to take DNA sequence from that specimen. Could you share please some apothecia from your material? 
Thank you in advance!

Re : Encoelia impudicella?
Hi all, could this species be instead related to Chlorociboria glauca? There is comparable collection from Igor, also on conifer: http://www.ascofrance.com/search_forum/77627

In 2018 I studied what I considered Encoelia impudicella in a living state: https://drive.google.com/drive/folders/1OidBhWWOCbhzCcDZ_0JDJqH-brIGkLQ7?usp=sharing

It looks very different, is IKI- and has VBs typical for Cenangiaceae (specimen was sent to Kadri at that time).

Re : Encoelia impudicella?
I did not know this docu. It is from the second sample of Ryszard as I see from your doc. I tried to compile the 140 spore measurements: 4.3-7 x 1.4-2.2 µm. Then I noticed your description saying (3,5)4,2-6,5(7,0)x (1,2)1,4-1,9(2,2) µm. Apo size is 2-5 mm? Karsten 1869 says 0.3-0.4 mm, but 1872 say 3-5 mm! The finally dark grey-brown outside is remarkable, but there are pale ones as well.

Did you get a result from Kadri?


The idea with C. glauca isn't bad, but I think the IKI reaction is too strong in Hulda's specimen, and I wonder also about what then the similar HB 4871 would be, with inamyloid asci and apos 0.7 mm diam.

Adam Polhorský, 30-03-2026 20:07
Re : Encoelia impudicella?

Yes, I did not send this before. Ryszard found this fungus 2 times, on Picea twigs beneath the snow, in a old growth Picea forests, which I think quite well simulate Scandinavian boreal conditions. Otherwise it is surely rare.


Judging by the associated Tryblidiopsis pinastri, your estimate of 2-5 mm must be correct. I do not have scales to Ryszards macro pics. If I assume that the Karstens description of 3-5 mm is correct. The Ryszards fungus fits the description remarkably, even by the colour of epithecium.


I dont think Huldas and Igors sample are exactly Ch. glauca, but perhaps closely related species. These collections deserve further attention. Yours HB 4871 I dont know what couls be:(


I dont have results from Kadri, I remember Ryszek kept the fungus in a fridge for a few days for me... I hope it didnt spoil the results.Â
