ventricose gills and paler colors. It was distinguished only once 

 and ii'» name is as yet applied to it. It is included merely for 

 comparison. It may prove to be a form of G. pygmaea-affinis Fr.

PILEUS 8-16 mm. broad, obtusely eonic-eampannlate, hygro- 

 phanous, pale ferruginous and striatulate when moist, whitish to 

 creamy-white and even when dry, glabrous, atomate when dry; 

 FLESH submembranous. GILLS ascending-adnate, close to sub- 

 distant, rather narrow, uniform in width, cinnamon when mature. 

 STEM 3-7 cm. long, 1-1.5 mm. thick, equal or subequal, straight, 

 slender, fragile, subshining, hollow, concolor (moist and dry), 

 prninose at apex, even or faintly striatulate. SPORES variable in 

 size, 11-16x6-9 micr., elliptical, smooth, obtuse. CYSTIDIA none. 

 STERILE CELLS on edge of gills capitate. 



<!regarious or scattered. Especially on lawns in our cities every- 

 where; also among grass by road-sides, in fields, pastures, etc., 

 sometimes on dung-hills. May to September. Throughout the 

 State. Very common. 



This must not be confused with Bolbitius tener Berk., which is 

 much more delicate and collapses quickly at maturity. When 

 growing in the same place the two are easily distinguished. 

 Bolbitius tener is rather rare, but may appear in similar situations. 

 There seem to be some discrepancies in the spore-measurements of 

 C. tenera as given by different authors, a fact easily explained by 

 their variability. The gills, too, are usually said to be "broad," 

 while in most individuals they are relatively somewhat narrow.
