Phialea? Helotium?

Dear friends,


There is one more tiny discomycete collected on thin branch. I examined this specimen in statu vivo (at least, it was not dry).


Fruitbodies light orange, stalked, disc 0,5-0,8 in diam. 


Asci IKI Blue


Spores elongated, 15-19-2,7-3,7 um, sometimes 1-septate, non-guttulate or sometimes with several small guttules.


Paraphyses with many septae (or with large guttules which make impression of septae), the apical cell is often non-guttulate, but in the lower part there are many small guttules. 


Also there are excipular(?) hyphae which contain some crystalline or dense substance. 


Is it some species of Helotium of Phialea?


These inoperculates are really difficult(


With best wishes,


Irina

Re : Phialea? Helotium?
Have you only one apothecium??

And are you sure this is a woody stem? Not herbaceous.

I can only guess for Cyathicula cyathoidea.

Phialea and Helotium are very old genera, not used anymore.

Re : Phialea? Helotium?

I have 2 apothecia.


Yes, the stem is probably herbaceous.

Re : Phialea? Helotium?
sorry, I did not read the spore size which excludes cyathoidea. I have no idea for a species. To be sure that it is Cyathicula, you should check the excipulum in a squash mount: ist it strongly gelatinized? Perhaps you can make a photo?

Re : Phialea? Helotium?

Zotto, sorry, but this is the only thing I see in squashed preparation and I'm not sure about gelatinous hyphae (see photo).


I re-measured spores and there is no mistake, really they are much longer than C. cyathoidea

Re : Phialea? Helotium?
Je pense qu il s agit de crocicreas coronatum pas tres typique = sans dents.
La taille des spores est 15-20 x 3-4µm.
la couleur de l'apothecie varie de jaune pâle à orange et même rose.
Toujours sur herbacées.
Amitiés
Didier

Re : Phialea? Helotium?
The preparation of the second photo would be good but it needs oil immersion to see the cells and their walls

Zotto,


Ok, I'll do it on Monday and show the photo

Re : Phialea? Helotium?

It's a pity, but the last fruitbody I had was infected by some mould fungus and I see mostly alien hyphae in preparation:(


By the way, I like the idea about teethless C. coronatus. 


Sincerely,


Irina
