the lack of any proper descriptioiij it seems superfluous to coini:»licato tlic synonymy further, and 
it must be confessed that Robin's figures, with their description, constitute quite as satisfactory 
a basis for determination as is afforded in the case of many other species.

Receptacle consisting of a slender rigid series of superposed cells from which arise suc- 
cessively in a unilateral series the appendages, and one, rarely two, pcrithccia. Pcrithccium 
flattened stalked. Appendages one from each cell, simple or branched, produced one or more 
below the origin of the perithecium, the rest above it. Spores once-scpfate. 
This well-marked type differs from other genera, from tlie fact that as many as three of the 
cells of the receptacle lying below the origin of the perithecia may give rise to appendages 
apparently fertile. The lowest of the latter which form the scries above the pcrithccium, also 
seem to be fertile, producing a small number (one or two) of ratlier slender flask-shaped cells; 
but no discharge of antherozoids has been observed from them. The cells immediately above tho 
origin of the perithecia bear no appendages, but the lowest sometimes produces a second perithe- 
cium. Tbe perithecium appears to have four cells in each series of wall-cells, but it has not 
been possible to determine this beyond question.

Perithecium suffused witli purplish, more deeply at the base and along its inner half, long, 
slender; the inner margin nearly straight, tlie outer curving inward distully to the prumincut 
somewhat angularly inflated tip; the stalk-colls bent upward at the base, so that the axis of tho 
per.theemra is nearly parallel to that of the receptacle, the lower short and narrow, Ihe upper 
becommg d.stally as broad as the perithecium, the basal colls of which arc not distinguished 
from It and are similarly suffused with purpli.h. Receptacle bristle-like, composed of about 
fourteen superposed suVcylindrieal or somewhat flattened cells, almost or quite opaque and 
.nd,stmgu,shab e, the series usually bent backward at the base and, more abruptly, at the apex. 
Of these cells the three (rarely tour) basal ones hear no appendages; above these one to three
