Protoblast lila3733fK.jpg

Protoblastenia lilacina, upper hymenium on the left, with the upper hymenium of P. rupestris to the right. These sections have been mounted in K and the initial K+ red-purple solution that dissolved out from the P. rupestris epithecium has largely dispersed. A proportion of the granules in the epithecium of P. lilacina have become reddish but without dissoving into a K+ red-purple solution.
