52 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 



the descriptions by Tulasne and Boudier so far as can be seen from specimen kept 

 in formalin. The peridium is irregularly areolate, salmon colored, usually about 100/j 

 thick, composed of densely packed tangled threads. Tramal plates continuous with 

 the peridium, considerably thinner than the peridium and much lighter colored, ap- 

 pearing almost white; glebal chambers rounded or elongated, usually filled with 

 spores, 0.5-1.5 mm. wide. Spores round, 13-17/* thick, light brown under the micro- 

 scope, very dark brown in mass, conspicuously set with large pyramidal spines and 

 often with a short pedicel. 



The following description is from Boudier, Icon. Myc. 4: 97: 



"Peridia white, rounded, solitary or cespitose, and more or less irregular, covered 

 with a light tomentum which is separated into small, tomentose, flatfish warts, white at 

 first, then turning smoky gray; cortex turning more or less bluish green by cold or ex- 

 posure to air; the peridia are attached to the earth by root-like, mycelial filaments which 

 form a very visible base. The gleba is full, firm, formed of rounded chambers, filled 

 with spores and separated from each other by the whitish plates which seem to arise 

 from the basal portion, and which are colored equally green by cold. The spores are 

 perfectly round, echinulate, brownish drab when seen one at a time, and purplish brown 

 when seen in mass, which makes a section of this species appear finely marbled with 

 white by the plates; they have a large internal oil drop often divided, and are often 

 furnished with a pedicel; they measure 15— 18/x in diameter with the spiny warts." 



"This species seems rare; I have found the specimens which I have figured in damp 

 woods of the forest of Montmorency in Sept. ; it was there in numbers under the leaves 

 at the foot of a clump of ash trees."
