Fig. 7. Hijgrophorus cuticle types — a, //. virescens: simple dry cutis, hypha< re- 

 pent, non-gelatinous, not sharply differentiated from the pilous traina; b, //. 

 saxatills: cutis, the surface hyphae repent, narrow, and loosely arranged. Since 

 the hyphae are slightly gelatinous at first | hut soon dr\ >. this type of cuticle 

 approaches an ixocutis; c, //. borealis f. borealis: cutis, some hyphae pericli- 

 nally arranged, others radial (seen as cut-ends in a tangential view); d. //. 

 mycenoides: cutis, the surface hyphae broad and the cells medium short, ex- 

 tending in a perielinal direction; e. //. pratensiSi cutis, with a few uplifted 

 hyphal ends, the surface hyphae hoth radial and perielinal in their direction; 

 f, H. gravcolens: cutis, with an occasional uplifted hyphal end; g, //. Mi/>- 

 australis: cutis, with few to many uplifted surface hyphae; when densel) 

 fibrillose, the cuticle is of a trichodeiinial type; h, //. marginatus VBI. mar^ina- 

 tus: cutis, with an uplifted cluster of surface hyphae forming a squamule.
