 place as those which caused the sickness, it does aol have very 

 striking characteristics, bul can be distinguished by the tendency 

 of the planl t<> assume an ochraceous <•!• dull clay color in age or 

 when bruised. Specimens which were doubtless the same species 

 were collected a1 Ann Arbor, September, L907, and August, L909, 

 and were ;it lirsi thought to !>•• T. nobilisj the Bpores, however, were 

 found t<> be elliptical and the plants could aol be placed until after 

 the publication of Atkinson's species. The Bpores of our plants 

 were ap to 8.5 micr. Long, the .uills rather broad, and the pileus 

 covered with delicate ochraceous, fibrillose scales excepl toward 

 the margin which was Bilky-fibrillose to Bilky-tomentose. Then- 

 was no odor ;it tii-st, i>ut ;i Blight, disagreeable odor developed. 

 The species seems closely related to the following, and apparently 

 imitates it in its general appearance. Eence both species should 

 be Lei alone.

PILEUS 5 LO cm. broad, convex expanded, subplane, obtuse, dry, 

 whitish, dotted by minute, droprlike grayish-ochraceous scales, at 

 leasl on disk, even, margin irregularly-wavy at maturity. FLESH 

 pure while, thick on disk, brittle, thin on margin. GILLS truncate 

 adnate, varying emarginate-adnexed to spuriously decurrent, broad, 

 close tu subdistant, while becoming dingy yellowish in age, edge 

 entire. STEM I 7 cm. Long, 8 L6 nun. thick, stout, equal, sometimes 

 Blightly tapering downward, solid, subglabrous, innately fibrillose 

 striate, white becoming dingy in age. SPORES minute, spherical, 

 smooth, Bubnucleate, 5-6 micr., white. CYSTIDIA and steriU cells 

 none. BASIDIA 35x5-6 micr. ODOB slight or Lacking; TASTE 

 at tii'st slight, slowly unpleasant or burning.

 stature and color, bul differs in its Blightly scaly cap and in Bpores. 

 In moisl weather the pileus appears watery-stained and this indi- 

 cates an affinity to the section Guttata, bul the presence of scales
