scure minute appressed squamules over apex .is seen undei a hand 

 lens, base paler than or concolor with apex. 



Spores L6-5 < 1-4.5 /*, subglobose, smooth, non-amyloid. Basidia 

 4-spored. Pleurocystidia none; cheilocystidia .is sterile basidia. (-ill 

 trama with a broad central strand of subparallel li\ phae, the subhyme- 

 niimi a narrow layer ot narrower hyphae on the outside slight!) diver- 

 gent toward the hvmenium. Kpientis ol pilens composed ol a palisade 

 of much-inflated cells, 50-75 x 15-40 f i, walls dingy olive-grayish re- 

 vived in KOI I. ('lamp connections absent.

 Hurt Lake, Mich., Aug. 4, 1961. 



Material Studded — Michigan: Smith 63826 (type). 



Observations — This species is distinct from //. rugulosus, the most 

 closelv related Hygrophorus 1>\ the hymeniform epicutis ol the pilens 

 (not as the end cells of a trichodermium), 1>\ the more parallel gill 

 trama and in particular by the colors of the dried fruiting bodies. In 

 H. riigulosas the pileus and gills are dull tan, whereas in //. rugulo- 

 soides they are drab. The dull olive color change in KOI I of //. rugulo- 

 soides is very likely an additional character, but fresh material of //. 

 rugulosus needs to be tested before a comparison can be made.
