Atkinson Gallery
Atkinson was a champion of all kinds of fungi, but he liked mushrooms best. 
Here's a mushroom that's a parasite on another mushroom.
The genus Endogone is weird. It looks like a blob sneezed onto the top of a moss.
This poisonous mushroom arrived in the mail. Atkinson named it Tricholoma venenatum.
Here's a mushroom named after Atkinson by one of his influential students, C.H. Kauffman.
Atkinson wrote seven books to help people learn about plants and fungi.
Atkinson was determined to sort out differences among American and European mushroom species.

Our tour through some of Atkinson's studies of fungi, illustrated by his own photographs.
The P. foenisecii test
"Dr. Robert Fries picked up Psilocybe foenesecii and
asked me what it is. I replied that it looked like Psilocybe
foenesecii. He laughed and said that species was the test of a good or poor mycologist!"
from G.F. Atkinson's 1903 European Diary.
Visit to the Sorbonne
"Imagine my feelings with this syphilis chimpanzee at my feet who was easy enraged."
from G.F. Atkinson's 1905 European Diary.
