This is one of the Furcatae. It is closer to R. sanguinca than 
any of the other species, but seems amply distinct from it. It is 
always pure-white and one of our firmest species as well as one 
of the most acrid. The spores of R. sanguinca are in all my 
specimens roughly echinulate, which is entirely different from 
those of this plant, which are adorned with strong raised lines 
forming a broken reticulation. I find it especially in pine woods 
during September and October. I have had it under observation 
for six years and find it remarkably constant.
