SUBSECTIOX CAMAROPHYLL1 373 



posed. Pileus trama of radially disposed hvphae. Clamp conneetions 

 present in the cuticle and gill trama. 



Habit, Habitat, and Distribution — Scattered to gregarious, very 

 common under conifers at elevations of 1000 to 4000 feet, Idaho. 

 Washington, and Oregon, September-December. 



Material Studied — idaho: Slipp 965; Smith 53621, 53883, .54056, 

 54391, 55016. Oregon: Gruber 708, 746; Sipe 766; Smith 18171, 19263, 

 20233, 26859, 26914. Washington: Bigelow 48887; Smith 16576, 17441, 

 17490 (type), 17528, 17695, 31351, 31631, 40179, 40954, 48740. 



Observations — H. bakerensis bears the same relationship to //. 

 variicolor that H. piceus bears to H. eburneus; it differs in having a dry 

 stipe. Abundant material was collected under nearlv all weather con- 

 ditions, and the stipe was never found to be furnished with even a 

 slight gelatinous veil. Dried specimens of both species appear identical. 

 The caps have a dull red-brown color and the gills darken appreciably. 

 The odor is easily missed if one has just a few fruiting bodies, but in 

 large collections it is very distinct.

Habit, Habitat, and Distribution — On soil, under tamarack 

 trees, New York, October. 



Material Studied — new york: Peck (type, from Davis Swamp, 

 Warrensburg, October ) . 



Observations — The description of microscopic characters given 

 above is based on our study of the type. 



Peck, in his original account, makes the following comments: "The 

 larch Hygrophorus grows under tamarack trees in a gregarious manner 

 and sometimes in great abundance. The cap in the young plant is very
