THE GENUS SARCOSOMA IN NORTH AMERICA. 
ELIAS J. DURAND. 
The genus Sarcosoma includes several large gelatinous Bul- 
garia- like Discomycetes. It was proposed by Caspary, in a letter 
to Winter, for the Bulgaria globosa Fries, and a new variety, 
var. platydiscus Caspary. The description first appeared in 
Rehm’s Discomycetes, page 497, 1891. In this place Dr. Rehm 
doubtfully referred tp it the Bulgaria rufa Schw., and this 
species has remained the only known representative from North 
America. In August, 1901, I collected, at Blowing Rock, North 
Carolina, two Bulgaria- like fungi which are referable to this 
genus, and I have thought it desirable to bring together at this 
time complete descriptions of such forms as are at present known 
to occur in our flora. All of the following descriptions were 
made by me after a careful examination of the living plants, and 
the changes made by drying have also been noted. 
SARCOSOMA Caspary, in Rabenh. Krypt. Flora, 1L497. 
1891. Burcardia Schmidel, Anal. Plant- 3:261. 1797. (not 
Schreb. 1789). Bulgaria Fries, Syst. Myc. 2:166. 1822, in 
part. 
A genus of the Bulgariacese. Plants not erumpent, sessile 
or stipitate, usually brown or blackish, at least externally, spongy- 
gelatinous. Asci long cylindrical. Spores 8, uniseriate, hyaline, 
continuous, elliptical. Paraphyses filiform, septate, branched. 
Differs from Bulgaria principally in the superficial habit, 
and in the hyaline spores. Plants of large size growing on half 
buried sticks and branches. 
A. Disk tawny-ochraceous 
B. Plants stipitate, watery-gelatinous, shrinking much in drying; 
spores narrowly elliptical, 18-25 x 8-12/* cortex parenchymatous. 
X rufum. 
B. Plants sessile, tough-gelatinous, shrinking but little in drying; 
spores broadly elliptical, 25-30 x 15/a, cortex not parenchymatous. 
.S’, carolinianum. 
A. Disk black, cinereous-olive when dry. 3'. cyttarioides.
