C. AMYGDALINUS 



d. SUBLURIOUS 



C PALUDOSUS 



Fig. 9. Hygrophorus cuticle types — a, H. fuligineus: an ixotrichodermium, with a 

 thick zone of slender, erect, pale hyphae imbedded in a gelatinous matrix 

 (represented by stippling) — all resting on an hypodermium; b, H. sub- 

 salmonius: an ixotrichodermium, a broad gelatinous zone (stippled), the 

 upper portion of clear gelatinous substance, the lower portion a turf, or ixotri- 

 chodermial palisade, of slender hyphae; c, H. amygdalinus: an ixotricho- 

 dermium, the hyphae fuscous, at times branched, resting on an hypodermium; 

 d, H. subluridus: an ixotrichodermial turf, or palisade, with slender, cylindric- 

 clavate hyphae; e, H. paludosus: an ixotrichodermium, similar to that in H. 

 fuligineus, but in the former the epicuticular hyphae are pale fuscous — all rest- 

 ing on an hypodermium.
