 7.5-9(10) x 4.5-5.5(6) p, ellipsoid, smooth, yellowish in Melzer's

 well-defined, composed of parallel li\pliae with an inner brown zone

Singer (1951) suggests thai both Omphalina australis Murr. and 

 CUtocybe praticola Murr. are synonyms. Our studies of the types <>l 

 each or' these species confirm his suggestion. 



The species is very common in the pastures and grassy areas of 

 northern California. In collections from shady habitats the stipes are 

 white; those from open fields had darker pilei and darker colored 

 stipes. The gelatinous pellicle is so thin that it can be easily over- 

 looked or lost in sectioning either fresh or dried specimens. It does not 

 appear to be sufficiently well developed to cause fresh wet specimens 

 to be truly viscid. On the basis of descriptions this species is very close 

 to H. subradiatus, if not actually identical. A critical study of these two 

 should be made.

Hygrophorus bakeri Dennis 



Kew Bull. 2: 258. 1953 



Illustration: 



Dennis, Kew Bull. 2, fig. 3. 



Pileus 2.5 cm broad, convex, umbilicate, avellaneous, glabrous, 

 slightly striate. Context white, very thin. 



Lamellae decurrent, white, narrow. 



Stipe about 3-5 cm long, slender, white, base attenuated, glabrous, 

 solid. 



Spores 6-8 X 5-5.5 /*, subglobose, apiculate, non-amyloid. Basidia 

 35-40 X 5-6 \x, 4-spored, cylindric-clavate. Pleurocystidia and cheilo- 

 cystidia none. Gill trama subparallel in the center of the gill, irregularly 

 woven toward its sides. Cuticle of undifferentiated, radiating hyphae. 

 5.-5-7 fx broad, non-gelatinous, with clamp connections. 



Habit, Habitat, and Distribution — On soil under bamboo, Trini- 

 dad. 



Material Studied — trinidad: Dennis II A (type, from St. Joseph). 



Observations — Dennis (1953) suggests that this agaric might be 

 sought in Omphalina, but the long basidia indicate an Hygrophorus. 

 He adds that H. albipes Pk. and H. sphaerosporus Pk. differ from it in
