figures (Plate 146, figs. 1, 2, 3, 5, and 6) whicli Persoou refers to his 

 H. compactum look much like our plants and I have seen no other 

 figures that do. Fries' conception of H. compactum is not so different 

 from our plant it would seem, except that in the latter there has not 

 been noted any olivaceous tint to the cap or bluish mottling in the flesh. 

 Banker thinks that the H. compactum of Persoon is probably the same 

 as H. floriforme and not the plant now referred to the former species 

 by European botanists today.

Plates 1, 22, and 29. 



Individual plants 1.5-5 cm. broad, the stems (in Xo. 1243) quite 

 distinct and not confiuent, but often branching at top into two or sev- 

 eral crowded and more or less fused caps, or (in jSTo. 1847a) several 

 short-stalked caps may arise from a fused basal stratum which is 

 deeply rooted. Surface smooth, not ridged or scrobiculate, usually 

 convex, or the margin later becoming uplifted, closely felted-tomentose 

 in unweathered parts, the margin undulate and lobed. Color of fresh, 

 unweathered plants and growing margins of weathered ones a pale 

 creamy buff (between pale yellow orange and white — Tiidgway), 

 which fades and deepens on exposure to rain to a sordid rusty broAvni 

 with a tint of chocolate, and then in age to nearly black. Flesh duplex, 

 the outer layer soft and spongy, buffy yellow and about 1-3 mm. thick ; 

 the much harder lower layer usually thinner and a lighter gravish 

 broAvn color; odor almost none; no decided taste (not sour or 

 peppery). After exposure to rain the soft flesh collapses and hardens 

 like horn either in whole or in part, the horny, black layers being 

 separated by lighter zones.. 



Spines slender, short, reaching a length of about 2 mm., wlion 

 young whitish (nearly color of young cap at very margin), tlic iimin 

 length below the tips soon turning a dark rusty brown (natal-l)rown —
