On a branch I found this white ascomycetes. Were also red ones in there. This may be a bacterium that is parasitic on the yellow? Last year I found it in the same location. Also lightly colored and later becoming red. I really have no idea in which direction to look. Can anyone help me on the right path?

Asci 56-86 x 6 microns, spores 4-7 x 2-3 microns. Hyphae with septa and at the top a button. I do not have a reaction with Lugol or Melzer.

Thanks in advance,
Hannie

Re : unknown asco
This should be  Calycina, there are species that change their colour in this way, but I cannot name a species. The major part of species have amyloid asci, so when it is actually inamyloid this would be a good character.
