I enrolled in a class in mushroom identification.
The teacher was a Ph.D. and the editor of a
publication on mycology. One day he picked up a
mushroom, gave a good deal of information about it,
mainly historical, and finally named the plant as
Pluteus cervinus, edible. I was certain that that
plant was not Pluteus cervinus. Due to the
attachment of its gills to the stem, it seemed to
me to be an Entoloma, and therefore very possibly
seriously poisonous. I thought: What shall I do?
Point out the teacher’s error? Or, following school
etiquette, saying nothing, let other members of the
class possibly poison themselves? I decided to
speak. I said, “I doubt whether that mushroom is
Pluteus cervinus. I think it’s an Entoloma.” The
teacher said, “Well, we’ll key it out.” This was
done, and it turned out that I was right. The plant
was Entoloma grayanum, a poisonous mushroom. The
teacher came over to me and said, “If you know so
much about mushrooms, why do you take this class?”
I said, “I take this class because there’s so much
about mushrooms I don’t know.” Then I said, “By the
way, how is it that you didn’t recognize that
plant?” He said, “Well, I specialize in the jelly
fungi; I just give the fleshy fungi a whirl.” |
