Hi,

what about Leucoscypha (Byssonectria) semiimmersa?

Hi,
could you please try to get free spores?
Thanks,
Marcel

Re : Any idea about this asco ???

The spores seem to be verrucose... It would be helpful to see free spores in Cotton Blue.

Spores with Cotten-Blue

Nicolas VAN VOOREN, 10-06-2015 13:47

Re : Any idea about this asco ???

Okay, so the ascospores are verrucose. No idea of the species, but it could be something around Tricharina and colored species of Leucoscypha.

Re : Any idea about this asco ???

Hello Nicolas,

can you really see that on the fotos? In the two fotos in which the focus is on the spore wall there is no sign of ornamentation of the wall. I can only imagine an ornamentation on some of the spores not coloured by cotton blue and in which the focus is on the surface instead of the spore wall. I think this could as well be internal guttules and are not necessarily ornamentations.

best regards,

Andreas

Re : Any idea about this asco ???

Andreas,
I made an assembly of some spores shown by Yasin. In my opinion the dots of irregular shape belong to the wall and are warts.

Re : Any idea about this asco ???

Hello,

yes I agree, it shows warts on the spores.

best regards,

Andreas
