Graddonia is inamyloid and grows hemiaquatic.

This one is away from water?
So perhaps again Tatraea, like the recent posting.

Re : asco 22-11-18
I assume that Luis Quiajda is interested in this collection if it turns out to be Tatraea. Did you keep it in dry state?

You don't have the possibility for oil immersion photos, e.g. of the amyloid ring?

Re : asco 22-11-18
I did not have more time.
I have it in the fridge.

I will try to make a better picture.

Thanks Otto !!!

I found some time and made better measurements from spore print

(15) 15.8 - 19.1 (19.8) × (5.3) 5.7 - 6.56 (6.6) µm
Q = (2.3) 2.5 - 3.3 (3.7) ; N = 30
Me = 17.4 × 6.1 µm ; Qe = 2.8

Re : Tetraea ??? 22-11-18
Yes, this looks to me like Tatraea sp. The scus apical ring in IKI you did not take with oil immersion?
Would you mind sending me the collection data to this (location, date)? Conifers and angiosperms are very easy to separate. If you succeed with a cross break or cut of the  wood at min. 20x magnification I can tell you.

Re : Tetraea ??? 22-11-18
Dear Vasileios

all the best for 2019!


I was talking with Luis Quijada about Tatraea and he is very interested in taking a sequence of your Tatraea for which Enrique now considered the name "Phaeohelotium" lilacinum as a possible identity. Would that be possible?


You will, if you agree, receive an official request from the Concord University in Massachusetts.


The I would need your email address, of course.

Thanks in advance
Zotto
