Laboulbenia forflculata dot. sp. 

 Perithecinm free, Btraight or somewhat curved, slightly inflated, brown 

 except the basal wall-cells which form a mostly hyaline well developed 

 narrow neck-like Btalk less than one third as long as the ascigerous portion, 

 the latter tapering rather abruptly at the tip, two of the lip-cells proloi 

 to form a pair of erect pointed hyaline symmetrical apposed outgrowths 

 which resemble the tips of a pair of shears. Receptacle Bhort, Btout, Bub- 

 triangular, cell I hyaline below, forming a short slender usually curved 

 pedicel ; the body of the receptacle suffused deeply below with blackish 

 brown, the more deeply suffused portions coarsely punctate with darker 

 spots. Appendages arising much as in L. palmeUa, the outer consisting 

 of a basal cell from the blackened upper and outer margin of which arise 

 u-ually three branches in an antero-posterior Beries, which are curved 

 slightly outward and give rise from their convex Bide to Becoudary 

 branches which in turn may bear branchlets in a similar fashion: of the 

 primary branches the inmost is more copiously branched, the outmost 

 being .-mall, usually broken ; all the branches black externally and brown 

 on the inner margins or wholly opaque, usually constricted on the inner 

 Bide at the blackened septa, the terminal cells of some of the ultimate 

 branchlets abruptly inflated at the base: the basal cell of the inner ap- 

 pendage gives rise to a branch on either Bide, the two divergent and very 

 similar in character and mode of 1. ranching to those of the outer append- 

 age. Perithecinm exclusive of neck. 150-200 X 28-38 p ; the neck I 

 50 ft long. Total length to tip of perithecium 300— I5() M ; to insertion- 

 cell 100-1 50 /x ; greatest width 50-70 /x. Appendages 175-200 /*.

Laboulbenia geniculata nov. sp. 

 Perithecium free, long and narrow, translucent olive-brown except the 

 shorl somewhat constricted hyaline neck, the tip well distinguished 

 blackish brown bent out ward, the lips coarse subhvaline oblique outward. 

 Receptacle nearly hyaline, except cell II and sometimes the upper part 

 of cell I, long and slender geniculate above cell II. Insertion-cell 

 broad, black, close to base of perithecial neck. Outer appendage con- 

 sisting of a larger basal subtrian«.nilar cell becoming more or lesssuffusi d 

 with olive-brown, surmounted by a Beries of five or six obliquely Buper- 



posed hyaline cells which curves inward toward the perithecium; each 

 cell of the series bearing externally a simple branch consisting of two 

 short faintly brownish basal cells constricted at the blackish sepia, and a
