REPORT OF THE STATE BOTANIST I9II IOI 



This species is well marked by having its pileus rugose when dry 

 and its lamellae brown from the first. Its somewhat bulbous stem, 

 firmly attached to its place of growth by its white basal tomentum 

 is also a noticeable character. Its brown spores, the incurved margin 

 of the pileus and the entire absence of a veil plainly indicate the 

 genus to which this peculiar species belongs.
