Chemical Tests for Lichen

It was suggested during today's British Lichen Society', Zoom Meeting, that we think about conducting Chemical Testing to determine Lichen' identifications!!!!! 

Starting with K (viz. Potassium Hydroxide) Testing: using Sodium Hydroxide in the form of Caustic Soda. 

A Solution must be prepared, comprising 10% Caustic Soda and 90% Water: the Solution is then applied to a Lichen.

We are entering 'Big Brain' Territory!

And we haven't started to think about using a Microscope yet!
