A very beautiful and peculiar species, distinguished from all others by its stout tooth-like auricles 
which make the tip of the perithecium appear bifid. Although scanty, the material is in fine condition, 
the host having been brought in alcohol by Dr. Dahl.

Receptacle usually rather long and narrow, the basal cell relatively large, hyaline or slightly suf- 
fused; the margins of the lower tier usually continuous with those of the middle one, the marginal cells 
deep blackish brown or quite opaque, the middle cell hyaline or translucent throughout its lower third 
often punctate: the middle tier consisting of about nine cells, slightly suffused with pale reddish brown 
externally, more or less edged with deep blackish brown; the terminal cells forming a free rounded pro- 
jection on either side, extending as high as about the middle of the rather large antheridia, the tips of 
winch may reach to the base of the perithecia: the upper tier nearly hyaline, consisting normally of 
from eleven to thirteen subequal cells, the terminal ones extending but slightly higher than the bases of 
the perithecia, which are normally two in number, rather deeply suffused with purplish brown through- 
out; the apex hyaline, the posterior lip-cells producing each a relatively large bluntly pointed appendage, 
the two diverging nearly at right angles to the axis of the perithecium, becoming slightly recurved, the 
distance from tip to tip about twice the diameter of the perithecium. Appendages nearly as long as the 
perithecia. Penthecium 60-70 X 16-20 /<, its appendages 18 ft. Receptacle 90-100 X 42-48 p. Total 
length to tip of perithecium 160-170 p.

A species peculiar for its long recurved auricles which are unlike those of any other species except 
U. "***»"'» from which its compact form, dark color, cylindrical auricles, and pointed tip seme readily 
to distinguish it. r~ r j
