‘The purpose of a key is not toidentify, but to eliminate’
Arora - part of Russula key
Reasons that keys do not work:
Species is not in it, because it is new to the area
Species is not in it, because author does not care for thiskind of species
Key characters are absent in your material
Key characters are too imaginative, and do not matchthe reality
Alternatives are not exclusive (cap green vs stipe red)
