290 SECTION HYGROPHORUS 



but in KOH slowly yellow and then dull orange ( on pileus ) ; on stipe 

 apex lemon-chrome changing to orange. 



Lamellae broadly adnate to decurrent, 2-3 tiers of lamellulae, white 

 to whitish, in age watery-grayish, distant or subdistant, broad, edges 

 even. 



Stipe (2.5)6-8 cm long, (4)8-12 mm thick, apex white, elsewhere 

 slightly grayish from a thin coating of fibrils, or no fibrils evident, equal 



Fig. 87. 



H. limacinus 



to enlarged downward, with a thick layer of hyaline gluten to near 

 apex, solid; no inner veil. 



Spores 10-15(17) X 6-9 /x, ellipsoid, smooth, pale yellow in Mel- 

 zer's reagent. Basidia 58-92 X 9-14 /*, 2- and 4-spored. Pleurocystidia 

 and cheilocystidia none. Gill trama divergent, hyphae 6-14(22) p. 

 broad. Cuticle a zone (120)300-450 /x thick, with fuscous, gelatinous 

 hyphae. Clamp connections present on the cuticular hyphae. 



Habit, Habitat, and Distbibution — On soil, under hardwoods 

 and conifers, Michigan and California, October and December. 



Matebial Studied— califobnia: Smith 56311, 56347, 56350, 56476. 



Obsebvations — Moser ( 1955 ) gives the spores 10-14 X 7-9 /*, and 

 Kiihner and Romagnesi ( 1953 ) 9-13 X 5.5-7.5 /*. We have examined 

 Peck's North Greenbush collection labeled H. limacinus, and find that 

 the pilei are shining, "warm buff" to "antimony yellow," and the spores 

 are 9-10.5 X 5-6 /x. Undoubtedly Peck's collection is H. paludosus. 



Hygrophorus limacinus differs from H. paludosus in lacking an 

 inner veil, and in its hyaline gluten. The dried specimens are almost as 

 dark as those of H. fuligineus, but in H. paludosoidcs the spores are 

 smaller and the fruiting bodies are larger.
