SUBSECTlOh HYGROCYBl 129 



hyphae. C ." 1 a n i p connections none. Among the repent hyphae of tlic 



cuticle are several hyphae with reddish-brown contents. 



Habit, Habitat, \\i> Distbjbi noN — On a lawn, nuclei oak. 

 Florida, [une. 



Material Studied — Florida: Murrill F16432 (type, from Dear 

 Gainesville, June s. L988). 



Observations — This species appears close to //. conicus l)nt is 



smaller and does not blacken when bruised or in age. When dried, the 

 pileus darkens normally, and the lamellae redden. The description of 

 microscopic characters given above is based on our study of the type. 

 In view of the reddish lamellae and very narrow spores there is a 

 strong possibility that //. conicoides Orton is synonymous.

Hvgrophorus arnoldae | Murr. I Murr. 



Llovdia 7: 326. 1944 



Hydrocybc arnoldae Murr.. Llovdia 7: 304. 1944. 



Pileus 3 cm broach conic to broadly conic, pale fulvous, disc 



fulvous, glabrous, not viscid, margin even. Context thin, white: odor 

 none, taste mawkish. 



Lamellae adnate, aurantiacous, distant, medium broad, many 

 short, edges even. 



Stipe 5 cm long, 6 mm thick, stramineous, apex with a narrow- 

 white band, equal above the tapering base, glabrous, hollow. 



Spores 5-7 X 3.5-5 /x, ellipsoid, smooth, pale yellowish in Melzer's 

 reagent. Basidia 30-43 X 5-7 /j., 2- and 4-spored. Pleuroevstidia and 

 cheilocystidia none. Gill trama subparallel, hyphae 3-6 /x broad. Cuticle 

 of repent, narrow (2. .5-4 ^) hyphae with some free ends, more or less 

 erect. Xo hypodermium. Pileus trama of radial hyphae. Clamp connec- 

 tions not found. 



Habit, Habitat, and Distbibutiox — On soil, under evergreen 

 oaks, Florida, July. 



Material Studied — Florida: Arnold, West, and Murrill F17S09 

 (type, from near Gainesville, July 11. 1938). 



Observations — Murrill comments that this is a pretty little species 

 with conic, fulvous pileus. orange gills, and pale yellow stipe, with a 

 white collar at the stipe apex. 



It is somewhat related to //. marginatus, but has a fulvous pileus 

 and distinctly shorter spores. The microscopic characters given above 

 are based on our study of the type.
