* Keys

‘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)

The questions are long, have AND or OR in them

Melanoleuca verrucipes, a recent additionto the California mycoflora, onwoodchips
