which, though distinctly smaller, have similar stiff upright appendages, and although it is not so ell 
developed, the perithecium has a distinct stalk. An examination ifl needed of i large number of tlwse 
cave forms, and it is barely possible that R. hypogenu may (end to v;iry toward the present species.

Receptacle slender, dirty translucent brown, the main axis consisting of about sewn ells (below tin 
lower of the two perithecia which are present in the type): the appendages slightly divergent, lar§ and 
long, opaque brown, flexed inward near their hyaline, souk what more slender extremities, and extending 
beyond the tips of the perithecia. Perithecium short-stalked, strongly curved, slightly inflated, hvnlii , 
soiled with brownish, the tips well distinguished, blackish brown and obliqudj truncate. PeriuVcia, 
including basal and stalk-cells, about 185 X 44 (L Receptacle to base of km r peritheeium 150 X lift.

The solitary type of this species which is well denned by the shape of its perithi cii and the haracfa r 
of its appendages, is illustrated in the accompanying plate. This specimen is DO doubt abnormal in pro- 
ducing two perithecia, the axis of the normal receptacle probably not consisting of more that ._«l«ajn 
cells at most; the distal portion in this specimen representing a proliferation such as is seen ... ■ asionally 
in most species of the genus, which gives rise to a second perithecium. The cave-dweUmg rtaphyl.n.d 
which it inhabits appears to be rare in collections.
