the subbasal cell producing apparently a single fertile branch which divid< al on<v, growing in opposite 
directions to form the somewhat irregular, and variably developed continuous secondary receptacles, 
which may creep more or It extensively; the component cell ... which an often vers numerous, being 
vertically elongated and becoming arranged in two more or less complete rov the inner mostl 
fertile, producing perithecia of which there may be twelve or rarely more; the outer be<-omin^ vera I 
times closely divided vertically, the cell-group which thus gi\. rise to ihe pcrilhceial stall lateral! 
connected with corresponding adjacent cell-groups throughout its lower third only, the upper two third 
forming a free, or nearly free, continuation of the perithecia] stalk, forming no free protective margin 
above, while below they develop a continuous, irregularly lobed, spreading haustorial margin in close 
contact with the host. Perithecia raised on a well-developed stalk, con ting of two mi qual and a yna- 
metrical cells placed side by side; that on the side toward which the tip of the perithelium i bent (anterior) 
attenuated below and extending higher than the posterior, which beoooM narrower upward from it 
broad base; the stalk becoming gradually and slightly broader from below upward, and directly con- 
tinued by the base of the perithecium from which it is not distinguis h ed. Ascigerom portion of the 
perithecium distinguished from the base by a very slight prominence, and about as long as the stalk and 
base combined; becoming distally slightly broader, the two lower tiers of wall-cells - panted by a slight 
elevation; the third wall-cell of the anterior row small, and forming a prominent elevation folloi ed b
