PILEUS 5-1 n nun. broad, fragile, ovate-campannlate then subei 

 panded and obtusely umbonate, bygrophanous, at i i 1 - -^ t viscid and 

 chest iiiit-tn '•own or rufous-brown and striatulate ichen moist, rery 

 soon buff with or without an ochraceous ambo when dry, glabrous, 

 subviscid. FLESH thin. GILLS broadly adnate, subtriangular, 

 thickish, subdistant, broad } at iir>t whitish, then umber. STEM 

 2-4 tin. Long, l 2 mm. thick, slender, equal or tapering downwards, 

 pallid to lust rsi cm, varying to chestnut brown within and without, 

 at first covered with delicaU white fibrils. SPORES <>v;ii or ovi 

 6-7x4-.~> niicr.. smooth, pale lirmvn tinged with wine-color under 

 microscope. VEIL slight, fugacious.

This approaches P. physaloides Fr. (sense of Ricken) in color, but 

 the ix'iUs arc not crowded and the spores arc smaller, h also differs 

 from /'. bullacea Fr. in the subdistant gills. The latter species is 

 doubtless native here, hut the discrepancies in the descriptions 03 

 the different authors make it difficult to place. Saccardo fol 

 Lowing Fries, says cap of P. bullacea is fulvous-baj color when 

 moist, and gives the spores 6-10x IT micr. ; Ricken describes the 

 Cap as chocolate-brown when moist, with spores Like our P. WUb 

 oiscida. Which of these, if any, is P. bullacea is therefore hard to 



tell; nevertheless it is desirable to follow the description Of Fl 



The chestnut <»r rufous-brown color, and the risiciditj quickly dis 

 appear and the pileus is then tan-colored and even.
