78 SECTION CAMAROPHYLLOPSIS 



The colors of var. robustus are apparently paler than in var. pratensis, 

 the stipe is much harder and more deeply rooting, and there is a color 

 change to yellow on injury which may also be significant. The photo- 

 graph (Fig. 20) shows young specimens.

Hygrophorus cremeus (Murr.) Dennis 



Kew Bull. 2: 257. 1953 



Omphalina cremea Murr., North Amer. Flora 9: 350. 1916. 



Pileus up to 4 cm broad, convex, then expanded, flat or slightly 

 umbilicate, warm buff to light buff, smooth, dry. Context white, thin. 



Lamellae decurrent, light ochraceous buff, broad, subdistant, 

 thick, lamellulae present, veined at base. 



Stipe white, dry, equal or slightly enlarged upwards, smooth, 

 solid. 



Spores 8-9 X 4.5-6 /x, broadly ellipsoid, with a large oil drop. 

 Basidia 35-40 X 7 /x, 4-spored. Pleurocystidia and cheilocystidia none. 

 Gill trama of interwoven hyphae, 5-7 /x broad. 



Habit, Habitat, and Distribution — On soil and decayed stump, 

 Trinidad and Jamaica, September to December. 



Material Studied — Trinidad: Dennis 73. 



Observations — Dennis ( 1953 ) has studied the type of Omphalina 

 cremea Murr., and, because of its thick gills and long basidia, con- 

 cludes that it is an Hygrophorus. He suggests that it might be treated 

 as a variety of H. pratensis with yellower gills and paler stipe than the 

 type. We have studied Dennis collection 73, and our observations are 

 as follows: Spores 7.5-9 X 4.5-6 /*, ellipsoid, smooth, yellowish in Mel- 

 zer's reagent. Basidia 37-46 X .5-6.5 /x, 2- and 4-spored. Pleurocystidia 

 and cheilocystidia none. Gill trama interwoven, hyphae 3-5 /x broad. 

 Cuticle not differentiated, surface hyphae repent, 3-5 /x broad, with 

 clamp connections. Pileus trama of radial hyphae. The dry pileus and 

 paler color distinguish it from H. pratensis.

Hygrophorus fulvosiformis (Murr.) Murr. 



Lloydia 5: 156. 1942 



Camarophyllus fulvosiformis Murr., Lloydia 5: 136. 1942. 



Pileus 3-4 cm broad, convex to expanded, turbinate, pallid to 

 avellaneous-isabelline, glabrous, dry, margin even. Context thin, white; 

 odor fragrant, taste mild.
