72 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 



turning brownish tan, covered with very delicate, hairlike spicules and granules with the 

 spicule tips usually free from each other. These are quite persistent but in old plants 

 are partly worn away at the top, thus exposing the light brownish gray shining surface 

 below. When the plants are exposed to the weather after maturity the granules and 

 spicules may be worn away over the entire plant, leaving it perfectly smooth, as in our 

 No. 3230. Pore apical and small. 



Spores (of No. 498) deep smoky purple when fully mature (but apparently going 

 through an olivaceous stage which may be found in herbaria, with the possibility of 

 confusion as to the real spore color), spherical, 4.4-5.5// thick (counting spines) , covered 

 with small blunt spines about 1m long, pedicellate, the greater length of the pedicels 

 being broken off and intermixed with the spores, the part remaining attached to a spore 

 about half as long as the diameter of the spore. Capillitium composed of long, brown, 

 unpitted, branched fibers attenuated at the ends and about 5-7. 5/u thick in the larger 

 parts. 



The typical form of this species as described above seems to run into forms ap- 

 proaching L. echinatum with longer, stellate spines, and Peck treated the latter as var 

 stellate of atropurpureum.

934. Under cedars east of campus, Oct. 17, 1913. Spores 3.7-4.8/t thick, not counting spines which 



are up to 1.5// long. 

 1019. Among leaves in woods, Nov. 26, 1913. Spores 4.4-6// thick, covered with blunt spines which 



are surrounded by a hyaline substance which gives the appearance of a halo. 

 7143. On ground in mixed woods, Sept. 26, 1923. Spores densely covered with blunt spines, 4.4-5.5// 



thick.

Plant 1.8-4.5 cm. broad and about the same height, tapering below to a slender 

 root, covered at first with very long, slender, pure white then pale tan spines, which are 

 united into groups by their tips and which finally fall away from the upper part of the 

 plant, leaving the smooth shining deep brown, purplish brown or silvery brown surface 

 of the inner peridium exposed and not reticulated. Gleba white then passing through
