variations of colour and stature, difficult to define. In the

 ochraceous, 14^-15 X 6 /*. (Cooke.) 



In Krombholtz, tab. 32, quoted by Pries under the present 

 species, the colour of the pileus is shown as umber, reddish- 

 brown, rufous, blood-red, orange, and yellow.

 glabrous, brownish-tan; tubes short, depressed round the
