nonco on the imicr side below the apex. Outer appendage hyalino, or with bi-o\vn shades, con- 
sisting of a large, stout, cylindrical basal portion nenrly equaling the receptacle in diamcfer and 
length, made up of a basal and somewhat shorter sub-basal cell, from the disfnl end of which 
arise two (rarely three) straight, very long and slender, tapering branches. Inner appendage 
arising from a very small triangular basal cell, its external wall directly continued by tlint of the 
outer appendage by which its upper surface is covered, its lower half cutting ofl" obliquely a 
small portion of the large black insertion cell ; its iipi'«T half producing sub-laterally a single 
short appendage, consisting of a single cell, bearing at its n]»ex two rather long antheridia. 
Receptacle characterized by a stalk-like, slightly inflaicd base, made nj* of cells 1 and 11, which 
arc very large, the cells of the distal portion, except cells IV and V, very greatly reduced, so 
that the perithecium appears to rise almost directly from cell 11. Cells IV and V clungnted, 
carry ini,^ the broad constricted insertion cell upward, free from the perithecium ; the axis of the 
receptacle coincident with that of the outer appendage. Spores, G0x5/a. rcrilhccia, 110 X
