White Calycina on hardwood
Enrique Rubio, 29-09-2012 12:41
Enrique RubioHi to all:
We have found this Calycina species on very wet eroded hardwood very close to the water level.
Apothecia, up to 1 mm in diam., are fully white, not reddening, stipitate and they have a convex hymenium.
No Chalara anamorph I have seen.

I think it's closely related (if not the same) with Calycina parilis.
What do you think?
Many thanks again
Enrique

Re : White Calycina on hardwood
Dear Enrique

wonderful, and I would not doubt to call this Calycina parilis. Good to see that you observed a blue reaction, because I have a drawing with a red reaction, the identity of which I am now a but unsure. In the type I observed a blue reaction. It could be that this is because of the age of the specimen, but I sometimes still saw the red reaction in more than 100 years old material.

Do you have any idea about the genus of the substrate?

Re : White Calycina on hardwood
No Zotto., I have no idea for the sustrate because the wood is very eroded for the water

Many thanks again
Enrique
