6V5-8 X 5-6 i'. Specimen tt/pienm in Herb. Mich. < <>n\en titum est, 



legit pr ope Apple gate, Oregon, Jan. 21. 1959. Fred Lawrenct 1162. 



Pileus 1-3 cm broad, broadly convex t<> plane, when mature 1 1 1« 

 margin uplifted, at first with a small conic umbo bu( tliis disappearing 

 in age 1 , surface smooth. dr\ and white. Context white, Fragile, odor 



Very Strong of Cedar, taste medicinal <>r almost like eed.u 



Lamellae decurrent, broad, distant, mtervenose, thi< k edges even, 

 white, drying dingy ochraceous. 



Stipe 1 3-6 cm long, 5-8 mm thick, widest at apex and tapered to 

 narrow base or subequal, smooth, white, dry. 



Spores 6.5-8 x .5-6 //. broadly ellipsoid to subglobose, hyaline in 

 KOIL pale 1 yellowish in Melzer's solution, smooth, thin-walled. Basidia 

 36-50x7-8.5 ^, 2- and 4-spored. Pleurocystidia and cheilocystidia 

 none. Pileus epicntis of narrow hyaline h\ phae not show ing an) appre- 

 ciable gelatinositv in KOI I. Clamp connections present. 



Habit, Habitat, \\i> Distribution — Under conifers. Vpplegate 

 Area. Oregon, Jan. 24, 1959. 



Material Studied — oregox: Fred Lawrence 1162. 



Observations — The fruiting bodies darkened to blackish in some 

 parts in drying, but this may have been due to overheating. The aspect 

 dried is that of H. recurvatus, to which it is closely related but is at 

 once distinct bv the white color throughout and pronounced odor and 

 taste. Kiihner and Romagnesi (195-3) include //. russocoriaceus in 

 Camarophyllus but ascribe spores 7-11 x 4-5.5 p to it. which is suffi- 

 cient to separate it from H. lawrencei. The two are obviously closely 

 related however.
