maturely dried, reddish and transversely cracked; ascigerous. 
cells globose, minute; asci obovate, 75-80X 40-45, subsessile, 
paraphysate, 8-spored; sporidia crowded, biseriate, obovate-ob- 
long, slightly curved, yellowish, obtusely rounded at the ends, at 
first 3-septate, becoming 5-7-septate and muriform, 30-40X 
15-204,

SARCOSCYPHA ALPINA FE. & E, 
On the ground, Nederland, Colorado, May 4, 1897. (D. M. 
Andrews.) Comm. Prof. E. Bethel, no. 238. 
Stipitate, 2cm. high. Stipe, 114 cm. high, about 2 mm. thick, 
clothed with short grayish-white tomentum, enlarged above into 
the cyathiform ascoma % cm. high, 3-4 mm. broad with the 
margin erect and sublobate, clothed externally like the stipe and 
with a few white spreading hairs, substance carnose, with a rose- 
colored tint; hymenium orange; asci cylindrical, 210-250X 
20-22; paraphyses stout, clavate, thickened above; sporidia 
uniseriate, elliptical, subinequilateral, subattenuated towards each 
end but obtuse, with one large nucleus and I or 2 smaller ones, 30— 
35X13-16p. 
Closely allied to S. floccosa (Schw.) but lacks the abundant 
spreading hairs of that species and has larger sporidia. 
TAPESIA TUMEFACIENS E. & E. 
On swollen dead stems of Bigelovia graveolens, Colorado, 
Jan., 1897. (E. Bethel.) 
Ascomata densely gregarious, or in broad strips erumpent 
through cracks in the bark, seated on a thin sporidesmoid subicu- 
lum, when fresh orbicular, about 2 mm. diam., mouse-color, 
disk concave, margin slightly incurved; substance soft carnose, 
cellular, the margin fringed with olivaceous septate straight hairs, 
about 75 long, and 3-4» thick at the tips; asci clavate-cylindrical, 
70-75 X8-10p, short-stipitate; 8 spored ; paraphyses stout, simple, 
subundulate above, about 2» thick, sporidia obliquely uniseriate, 
elliptical, hyaline, 8-11 5-6. : 
When dry the opposite sides of the ascomata are rolled to- 
gether in a hysteriiform manner. The habit is that of Angelina 
vufescens Duby. . The.mycelium penetrates the wood and causes 
the stems to swell in the same manner as Montagnella tumefaciens 
E, & H.
