Tuberculate Pholiota. 
Pholiota tuberculosa is similar to Pholiota flammans but 
the scales are concolorous with the background or darker, and 
there is a beautiful round bulb at the base of the stem. The 
illustration in Fries, Icon. 104, represents our plants exactly.

Note. Pholiota hormomorpha, Mont., described from plants col¬ 
lected at Columbus, Ohio by Sullivant is said to be very similar to 
Pholiota tuberculosa. The stem is thickened at the apex as well as 
bulbous at the base and naked. Spores oblong. 
Pholiota curvipes, Fr. is reported from this country by Peck, Hard 
and others. In Farlow’s Index it is given as identical with Pholiota 
tuberculosa and according to Longyear it has been confused with Pho¬ 
liota muricata in this country.
