REPORT OF THE STATE BOTANIST I906 49 



Woods and open places. Common. August and September. 

 Single, gregarious or cespitose, 



Var. u n i c o 1 o r Pk. Pileus wholly white or only faintly 

 tinged with yellow. Warren county. September. Edible. In this 

 variety and in the typical form both pileus and lamellae become 

 darker colored with age or in drying, but in the lamellae the change 

 is more pronounced than in the pileus. 



Var, d e c i p i e n s Pk. Pileus thin, white with a dingy yellow 

 or smoky brown spot in the center; lamellae subdistant, stem long, 

 slender, white ; pileus and stem not changing color with age or in 

 drying, lamellae changing color slightly. Cespitose; borders of 

 woods. Hamilton county. September. Edible. 



More slender than the typical form and differing specially in the 

 persistent colors of the pileus and lamellae. Closely related to the 

 next following species. 



(Hygrophorus rubropunctus n. nom. 



RED DOTTED HYGROPHORUS 



(Hygrophorus glutinosus Pk.) 



State Mus. Bui. 54. 1902. p. 950. 



Pileus fleshy, firm, convex, glutinous, white, sometimes tinged 

 with yellow by the drying of the gluten, involute on the margin, 

 flesh white ; lamellae subdistant, adnate, white ; stem equal, solid, 

 white, floccose tomentose below the glutinous annulus, studded above 

 with drops of moisture which in drying form reddish glandular 

 dots; spores elliptic, .0003-.0004 of an inch long, .0002-00024 

 broad. 



Pileus 1-2 inches broad; stem i-i. 5 inches long, 3-4 lines thick. 



Open places. Warren county. September. Rare. In the fresh 

 plant the lower part of the stem appears to be coated with tomentum 

 smeared with gluten, but in the dried plant the gluten assumes an 

 orange-yellow or bright straw color and the tomentum disappears. 

 The species dififers from H . 1 a u r a e Morg. in its white pileus, 

 persistently white lamellae, reddish dots at the top of the stem and 

 in the tomentum of the lower part of the stem. A g a r i c u s 

 glutinosus Bull., in its transfer to the genus Hygrophorus 

 to which it belongs, was consigned to synonymy, therefore according 

 to the rule " once a synonym always a synonym " it becomes neces- 

 sary to change the name Hygrophorus glutinosus Pk. 

 This has been done by substituting for it the name H y g r o -
