 344 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



On sandy ground in swamp. Florida. September. 



Only a single fructification was collected; the description is 

 based upon this dried specimen. The species is distinguished 

 by its fan-shaped, triangular pileus and the comparatively long 

 and slender stem. Its characters are those of a true Crater ellus 

 and yet such that we cannot regard it as a flabellate form of any 

 other species. 



Specimens examined: 

 Florida: Sorrento Swamp, R. Thaxter, type (in Farlow Herb.). 



17. C. Humphreyi Burt, n. sp. Plate 17. fig. 22. 



Type: in Burt Herb, and in Humphrey Herb. 



Fructifications gregarious, fleshy, moderately tough and 

 flexible, entirely white, usually with the pileus standing out 

 horizontally at the apex of the erect stem; pileus reniform, 

 dimidiate, sometimes clasping behind, convex, becoming plane 

 or somewhat depressed, usually even, dry, minutely pubescent, 

 the margin entire, even or slightly crisped; stem lateral, erect, 

 often bent at right angles just before joining the pileus, cylindric 

 below, equal, solid, pubescent; hymenium nearly even, some- 

 times radiately venose near the stem, brittle when fresh; 

 spores white, even, subglobose, 3^-4^ x 3^ m- 



Fructifications 3-7 cm. high; pileus 6 mm. - 2 cm. long, 1-3 J 

 cm. broad, f mm. thick; stem 2f-6 cm. long, 2 mm. thick. 



On humus and among mosses in low swampy thicket. Wash- 

 ington. October. 



The habit of this curious species is very suggestive of Hydnum 

 auriscalpium; many of the specimens have the erect stem bent 

 at right angles near the apex so that the pileus extends out in a 

 horizontal plane. Sometimes the stem branches at its upper 

 end and bears two pilei. The pubescence on the stem is rather 

 coarse and is most abundant towards the base. All parts of 

 the fructification were rather brittle in vegetative condition, 

 and broke when bent too far. It is a connecting species be- 

 tween Craterellus and Arrhenia, but with the hymenium rather 

 too even for Arrhenia, in my opinion. 



Specimens examined: 

 Washington: Hoquiam, C. J. Humphrey, 1386, type.
