Neodasyscypha cerina + pyknidium
Perz Piotr, 06-03-2010 22:37
Hi!

Today I have seen Neodasyscypha cerina closely assoc. with small, blackish-brown pyknidia. The wall of this pyknidium looks like ectal excipulum of N. cerina and also ist with brown warted hairs, but apressed.

The larger version of the pictures and table is here:

Re:Neodasyscypha cerina + pyknidium
Did you know the pycnidia? Did you seen such pycnidia in othe collections? Inside I have seen only gelatenized tissue, without any conidia or other structures. What is anamorphic fructification of this species?

regards
Piotr

Re:Neodasyscypha cerina + pyknidium
I have never noticed such structures in my many collections of this species all over the world. Maybe Zotto has. Why do you call them pycnidia when there are no conidia? The are more likely to be sclerotia, though whether they have anything to do with the apothecia seems an unknown. Cultures might be interesting to see whether both ascospore and pycnidial isolates result in the same kind of culture.

Re:Neodasyscypha cerina + pyknidium
Thank you, Dick.
Of course "pycnidia" was wrong and sclerotia seems to be the best name.
