150 SECTIOX HYGROCYBE 



Observations — Dennis (1953) states that a possible synonym is 

 H. siparius Berk., from Brazil, but he could find no spores on the type 

 (Spruce 130, at Kew). The obvious dimorphous basidia are a striking 

 feature of this variety. 



Notes on Dennis collection No. 48: Basidia dimorphous, larger 

 ones 42-57 X 10-14 ft, 4-spored, spores 13-18 X 7-9 p.; smaller ones 

 28-35 x .5-6 ll, 2- and 4-spored, spores 5-6 x 3-3.5 ll; all spores el- 

 lipsoid, smooth, yellowish in Melzer's reagent. Pleurocvstidia and 

 cheilocvstidia none. Gill trama parallel, hyphae 6-17 ll broad. Lactifers 

 present in pileus trama. Cuticle not differentiated, surface hyphae 

 repent to erect, 15-32 ll broad. Clamp connections not found. 



75 



Hygrophorus firmus var. militaris Corner 

 Trans. Brit. Mycol. Soc. 20: 177. 1936 



Pileus up to 4 cm broad, convex then flattened or depressed with a 

 downcurved margin, scarlet red with a yellow line at the margin, 

 silkv, dry. Context red. 



Lamellae broadly adnate, light orange-yellow becoming apricot- 

 orange with yellow edges, rather crowded, of two lengths, intervenose 

 in age. 



Stipe white with a hint of vellow at the base, becoming orange-buff 

 from the base upwards with age, dry, smooth, equal, hollow. 



Basidia dimorphous, the larger mostly 4-spored, a few apparently 

 2-spored, 40 X 7-10 ll, the spores 8-11 X 5-6 ll; the smaller 30 X 5 ll, 

 4-spored, the spores 6-7 X 3-4 ll. Pleurocvstidia and cheilocvstidia 

 none. Gill trama parallel. Cuticular hvphae parallel, the cells 270-400 X 

 15-30 tx. 



Habit, Habitat, and Distribution — Gregarious in forest litter. 

 Trinidad, November. 



Material Studied — trinidad: Dennis 382. 



Observations — Apparently this variety differs from var. firmus by 

 its lack of squamules on the pileus, its larger size, its crowded, orange 

 gills, its stipe color, its smaller spores. 



Dennis points out that H. subcaespitosus (Murr.) Murr. from 

 Jamaica has a similar habit, but the gills of the latter are white to 

 stramineous and the stipe vellow. 



Notes on Dennis collection No. 382: Basidia dimorphous, the 

 larger 46-57 x 8-12 /x, 2- and 4-spored, the spores 9-11 X 5.5-7 ll; 

 smaller, 32-42 X 5-6 fx, 1-, 2-, and 4-spored, the spores 5.5-7 X 3-4 fx, all 

 spores ellipsoid, smooth, yellowish in Melzer's reagent. Pleurocvstidia 

 and cheilocvstidia none. Gill trama parallel, hyphae 6-18 \x broad.
