186 JOUEXAL OF THE MiTCHELL SoCIETY [Mavch 



clear flesli-pink or onion-skin pink, darkening by distinct zones 

 tlirougli pinkish-cinnamon brown to deep Vandyke brown or pecan 

 brown in center; radiating ridges are usually ratlier distinct. Flesh 

 thin, firm,. tough, homogeneous, but zoned, color of surface, about 3 

 mm. thick near center, very thin towards margin; taste and odor 

 woody, or, in 'Ko. 1849, faintly like that of Mutinus. 



Stem usually short, 0.5-2 cm. long, 4-6 mm. thick at top, much 

 stouter below, pinkish when young and then darkening like cap. Flesh 

 solid and same texture throughout, somewhat harder than the cap, 

 darker than the surface when young, of the same color when old. 



Spines small, rather blunt, not fimbriated. From 1-2.5 cm. long, 

 pinkish on the very edge, but soon becoming a deep rich brown like 

 the darkest parts of the cap. 



Spores (of ISTo. 1238) light smoky-purple, subspherical, coarsely 

 tuberculate, one large oil drop, 3.4-5/* in diameter. 



"While our plants show the pink margin in most cases it is well to 

 note that this color may not be observable when the plants are col- 

 lected. 



These plants would seem to be as easily referred to H. vespertilio 

 as to H. zonatum, except for the absence of the scabrous yellow dots 

 that Banker says are characteristic of that species (Mycologia 5:199. 

 1913). Perhaps the two species are not distinct. H. concrescens is 

 also very near if not the same.
