Re:Wall or Sheath
You would have to use Black ink to see the sheath.

Re:Wall or Sheath
I also recommend to use Cresyl blue (aqueous). Many gel sheaths stain bright lilac herein, but sometimes distinct sheaths are negative.
I also know the problem that the spore wall consists of several layers. F.ex. in Sarcoscypha the two layers are wall material, not gel sheath, but behave different: the outer layer is rigid and gets folded and separates when the inner elastic layer shrinks during turgor loss. The surface of the outer stains lilac in CRB which means a very thin gel on it.

Re:Wall or Sheath
thank you very much Zotto!
I have got ascospores with many layers and I whant to differentiate if the outter one is a sheat or not.
Your explanation is very useful, I will try with the cresyl blue.

Re:Wall or Sheath
Hi Romina,
the sheaths of ascospores are of different chemical structure, which implies they react differently with stains. Aqueous nigrosin and chlorazol black also might be very useful, they sometimes also stain the appendages.
Cheers,
Jacques
