ini^ with it, as is usually the case ; so that all tlie younger asci arc seen pointing outward and 
downward (Plate III, fig. 3). The spores are unusually minute in proportion to the size of the 
peritheciuin, and it is possible that the asci may be eight-sporcd. Seen within the perithecium, 
however, they seem to be four-spored. 
RiiTZOMYCES CTENOPHORUS nov. sp. Plate III, fig. 3 ; Plate lY, figs, 1-4. 
Pcrithecium, including its basal cells, dark amber brown, asymmetrical, the lower half some- 
■ 
what inflated, tlic rather truncate tip not distinguished from the tapering, neck-like, slightly bent 
upper half; the sub-terminal wall-cells marked by fine transverse striations ; the lower half not 
distinguished from the basal cells, which are themselves abruptly distinguished from the Ions 
slender, cylindrical stalk-cell. The basal cell of the receptacle rounded bulow, nlxjut lialf ns 
large as tlie sub-basal, the rhizoids rather copiously and irregularly branclied or lobcd, colorless. 
Appendage shorter than the stalk-cell of the perithecium ; the axis simple or exceptionally fur- 
cate near the base, consisting usually of about thirteen superposed cells ; the basal cell small, 
blackened and somewhat constricted; the rest producing anthcridial branches always on the 
same sidt>, forming a unilateral series; the branches in turn several times more or less sympo- 
diully branched ; the branchlcts. distally somewhat indurated and suffused with blackish brown, 
the whole forming a comb-hke tuft; the ultimate branchlcts curved outward and downward. 
Antheridia long, flask-shaped, sessile, borne rather irrcgularlv, one to four together, from the 
upper surface of the basal cell of the antheridial branch; sometimes also from tlie sub-basal cell. 
Spores, 25 xS/x. Perithecium, including basal cells, 180-200 x 62-70 /x ; smallest, 120 X S5 fi ; 
the stalk-cell, 275-620 x -35 ;. ; average, 550/. long. Appendage, longer, 325-340^; greatest 
diameter of axis, 17 f. ; antheridial branches, longer, 45-50 /x. lleccptacle, GO X 45 /.. Rhizoids, 
long^cr, 86 x 13 ^. Total length to tip of perithecium, longer, 800-880.
