1911] Davis,— Fleshy Fungi of Stow, Massachusetts 65 
Apparently he was deceived by buttons that were cupola-shaped; 
“petasiformis” is his exact word; if he had waited for his buttons to 
develop he would never have tried to create such a mendacious variety. 
I found, however, a very curious departure from the type in a plant 
which was entirely orange. Fries notes this possibility in Hymen. 
Europ. and speaks of this species as changeable in color and variable 
in size, all of which I have observed since 1906. The plant is perfectly 
edible, fresh or dried. 
Pluteolus callistus Pk., one plant only came to hand in August. 
It was not typical but was easily recognized by structure, color of 
spores in mass and habitat. I have collected a very few plants each 
season since 1907. I always find it in swamps growing from decayed 
maple or tamarack. 
I believe it a very rare plant. When in good condition and fresh 
the pileus is a rich “Indian Yellow” with the center a bright deep 
yellow orange; stem pale citron yellow-above, duller below owing 
to a whitish or greyish pubescence which covers it; gills a dull pale 
ochraceous yellow, adnexed, and finely uneven on the edges as may be 
seen under a lens; flesh of both pileus and stem bright citron yellow. 
It will be noted that I have always found it on decayed, rotten wood 
and not in “exsiccated water holes in low swampy woods” as described 
by Dr. Peck. The determination was confirmed by Dr. Peck. I 
should add that the colors are transient. 
In conclusion I beg to suggest to fellow students the wisdom of 
sticking to one locality. Dr. W. G. Farlow impressed this upon me 
some years ago, and I know from experience that his advice was cor- 
rect. You can never exhaust one locality, probably, but whether you 
can or cannot, is not the point as I see it. Yearly observations, 
intelligently conducted, enable us to note any differences in species - 
and consequently to check the multiplication of alleged new species 
"that have no real claim to specific distinction.
