Note 162 — DESCRIPTION OF SPECIES.

“It is commonly supposed that such funguses as change colour afford thereby a clear evidence of their noxious properties, and yet daily experience, as far as it went, ought to have led to just the opposite conclusion. Almost all the poisonous Agarics have a flesh that does not change colour, and we know as yet of no Boletus, many of which do so change, that is really unsafe to eat.”—Vitt.
