88 PROCEEDINGS OP THE AMERICAN ACADEMY. 



branch. Antheridia simple, flask-shaped, free, borne in small groups on 

 short branchlets. 



Stichomyces Conosorriae nov. sp. 



Dull amber brown. Receptacle and appendage undifferentiated, the 

 basal cell of the former small, triangular in outliue ; the subbasal cell 

 about as broad as long, and similar to the cells of the appendage, bearing 

 distally and laterally a single perithecium, sometimes two, which are then 

 paired on opposite sides of the cell, like the antheridial branchlets. Ap- 

 pendage consisting of five superposed subequal cells slightly longer than 

 broad, the basal one sterile, or rarely (abnormally) producing one or two 

 perithecia as in the subbasal cell below it : the three cells above slightly 

 larger, the upper angles separated by oblique septa to form small cells 

 on either side, which bear short one or few celled antheridial branchlets ; 

 the terminal cell somewhat smaller, bearing a simple terminal several- 

 celled branch in addition to the lateral branchlets, all of which appear to 

 be sterile. Antheridia with broad necks grouped in twos or threes. 

 Perithecium darker brown, more or less symmetrically inflated ; the tip 

 hardly modified; the basal cells collectively broader and nearly as long 

 as the stalk-cell. Spores 35 X 2.5 fx. Perithecia 85 X 25 /x, the stalk- 

 cell 36 x 1 t /x. Total length to tip of the appendage proper 150 «, the 

 terminal branch 150 fx, the antheridial branchlets about 20 /x. Total 

 length to tip of perithecium 185-200 ft. 



On Conosoma pubescens Payk. Belmont and Waverly, Mass. First 

 observed by Mr. Dullard. 



Rhachomyces Oedichiri nov. sp. 



Receptacle strongly curved, rather short, the lower cells especially 

 more or less suffused with clear brown, the basal cell slender, the cells of 

 the main axis above it successively larger, about ten to twelve in all. 

 Appendage hardly ever reaching to the tip of the perithecium; the shorter 

 margin alone subulate and straight, the rest appressed, denser toward the 

 base of the perithecium, where they form a tuft which does not wholly 

 surround it, curved slightly outward, somewhat attenuated; tips abruptly 

 recurved or subhelicoid. Perithecium somewhat inflated, hyaline, with 

 the exception of several longitudinal dark brown marks at the tip, the 

 base concealed by the appendages. Spores 36 X 4 m. Perithecia 90- 

 1 10 X 30-35 (i. Total length to tip of perithecium 220-250 /x. Long- 

 est appendages about 90 u.
