THE FUNGI OF BLACKSBURG, VIRGINIA 



W. A. MuRRILL 



During the latter half of July, 1920, the following fungi — over 

 150 species — were found by the writer in the vicinity of Blacks- 

 burg, Virginia, mostly in oak-chestnut groves with white oak 

 predominating. The elevation is 2,200 feet and the underlying 

 rock near the town is Trenton limestone, while on Brush Moun- 

 tain, a mile or two to the north, the soil had its origin in subcar- 

 boniferous shales and sandstones. On account of the excellent 

 season, many valuable field notes and several novelties were ob- 

 tained, especially of the fleshy forms. Attention is called to ob- 

 servations in connection with Ceriomyces retipes, Hexagona 

 alveolaris, Vaginata plunibea, and Venenarius cothurnatus. 



A. ASCOMYCETES 



Bulgaria rufa. More abundant than I have ever before seen it, on fallen 

 dead branches and trunks of white oak in Preston's Woods and elsewhere. 



Hypomyces lactifluorum. Common where I found it last year and enjoyed a 

 mess of it mixed with the common Chanterel. 



Leotia stipitata. 



B. HYMENOMYCETES 

 a. Tremellales 



Tremella frondosa. 



Tremella mycetophila. On Gymnopus dryophilus. 



Tremella sparassoidea. Under white oak. See figure and description by 

 Overholts in Mycologia for May, 1920. 



b. Agaricales 

 1. Thelephoraceae 

 Craterellus cornucopioides. Found three times. 

 Lachnocladium Schweinitzii. Abundant. 



Thelephora spp. Three or four interesting species, mostly of the T. palmata 

 group. 



2. Clavariaceae 



Clavaria cristata. Found twice on a hillside in Preston's Woods growing in 

 dense clusters among grass and leaves. Lemon-yellow, with a distinct odor 

 difficult to define, the taste bitterish but not farinaceous. 



Clavaria fiava. Frequent in shaded situations.
