Plates 21 and 29. 



Plant solid and heavy, of medium size, our specimens about 4.5-5.5 

 cm. broad, the cap rather regular and only slightly lobed or compli- 

 cated, slightly to distinctly depressed in the center, the blunt margin 

 sterile and pale below; surface finely felted tomentose or on expan- 

 sion mostly smooth, even or more or less pitted, not zonate, color pale 

 buff or dull tan or mottled with deep brown on exposure, the growing 

 parts becoming blackish when rubbed. Flesh zonate towards the 

 margin, duplex but not so sharply contrasted as in H. velutinum, P. 

 amicus, etc., a rather thick, buft'y upper layer of a firmly corky tex- 

 ture, passing more or less abruptly into a hard and darker brown 

 laver below. Odor verv faint, sliffhtlv mustv, as is also the taste. 



Spines up to 4 mm. long, not very slender, rather bluntly pointed 

 when fresh, sharper when dry; pale grayish at the margin, passing 

 through light to dark gray-brown, with a tint of salmon at times, and 

 then to deep brown, the tips pallid until age. 



Stem short, about 2-3 cm. long and 1-1.5 cm. thick, rusty red, the 

 context consisting of a very hard and rather slender core of dark, dis- 

 tinctly longitudinal fibers, surrounded by a rather thick woody-corky 

 layer of more radiating fibers of a reddish bro"um or rust color, only the 

 surface of which is distinctly soft. 



Spores (of Ko. 3201) subspherical, smoky brown, papilliate- 

 warted, 4.6-5. 6^, some more elongated as 4.5 x 6,5/a. 



Differs from H. florifo?'me in pale color, in thicker and more com- 

 pact flesh, in longer and stouter spines, in absence of a fragrance and 

 in the distinctly larger spores. Hydnellum complicatum Banker 

 differs in color and in the thinner cap and smaller spores. Shaeffer's
