at right angles ; below which the distal end of the outer wall-cell forms 

 a slight rounded prominence, the very small lip-cells forming a slight 

 enlargement. Appendage similar to and continuing the axis of the 

 receptacle directly, or diverging very slightly ; the cells giving rise 

 to brandies on opposite sides which are subtended by small cells 

 obliquely separated at the distal angles, those from the lower cells short 

 (antheridial ?), those from the upper long and several times branched ; 

 the main appendage usually broken, but in young individuals consisting 

 of from twenty to twenty-five superposed cells. Spores 48 X 3 p. Peri- 

 thecia, ascigerous portion 175 X 45-50^, beak-like termination 140- 

 160 fi, sterile basal portion about 100 p. Receptacle 270-430 X 30-35^. 

 Appendage (young individuals) 350//, the branchlets 200 X G ^. 



On Phcenonotum estriatum Say. Eustis, Florida, October. On legs 

 and inferior surface. A form growing on the lower surface of the apex 

 of the elytron has enormously developed perithecia with a maximum 

 length of one millimetre. 



Ceratomyces reflexus nov. sp. 



Closely allied to C. rhynchophorus. Hyaline with a few purplish or 

 reddish suffusions on the receptacle, which is composed of from about 

 twenty-five to fifty superposed cells ; the foot hyaline, or slightly yel- 

 lowish, much enlarged, bladder-like or spherical ; the distal portion dis- 

 tinctly broader, its axis coincident with that of the erect appendage which 

 forms a direct continuation of it. Perithecium small with few asci, 

 abruptly recurved at the base, its apex thus sometimes touching the in- 

 flated foot ; nearly straight, tapering almost symmetrically to the blunt 

 slender tip ; the ascigerous cells situated at the base just above the small 

 angular stalk-cell. Appendage usually flat and broader than the recep- 

 tacle towards its base, the superposed flat cells of which it is composed 

 producing appendages on either side much as in O. rhynchophorus. Spores 

 70 X 4 f i. Perithecia 140 X 20 ;/. Receptacle 140-280 p. Appendage 

 200-400 (i. Foot about 30 X 30-38 (t. 



On Phcenonotum estriatum Say. Eustis, Florida, October. With 

 C. rhynchophorus. 



Ceratomyces acuminatus nov. sp. 



Hyaline. Receptacle consisting of three superposed cells, the basal cell 

 partly suffused and continuous with the blackened foot. Perithecium 

 rather stout, the outer margin nearly straight, the inner strongly convex; 

 the seventh wall-cell of the inner row greatly enlarged, its outer wall
