Paxillus involutus f. cul. inedulis-incognita

inedulis: NO RESIDUAL IS ACCEPTABLE, so no method is offered -- and no chemistry is established to state in front of the warning. The word is about the ENDPOINT, not the route: a route may well exist and the word still applies, because the reduction cannot be taken low enough. Where the chemistry IS established the term is compounded, as `solubilis-fickeana-inedulis`. Bare `inedulis` says only that no residual is acceptable and that nothing is yet known about how the molecule behaves.
