CHITONOMYCES AND RICKIA. 51 



terminal, and sometimes the snbterminal, bear single pointed antheri- 

 dia, the upper more or less appressed externally beside the base of the 

 perithecium: posterior series similar to the anterior, consisting of 

 eleven or twelve cells all cutting off cells which bear appendages only; 

 the series surmounted by the free base of the primary appendage 

 which diverges almost at right angles, its basal cell cutting off a sec- 

 ondary appendiculate cell distally on the lower, or sometimes on the 

 upper side: median series consisting of usually twelve cells, the upper 

 four or five extending beside the base of the perithecium and beyond 

 the insertion of the base of the primary appendage; the basal cell 

 longest, and intruded between the third pair of marginal cells. Ap- 

 pendages strictly marginal, of the usual type; becoming faintly tinged 

 with yellowish brown, stout, rather short, usually broader above the 

 constricted base: the primary appendage usually more or less per- 

 sistent and smaller. Antheridia usually single, quite hyaline, spine- 

 like, without differentiation between the neck and venter, or the 

 usual constricted and suffused base. Perithecium almost free; its 

 inner margin, only, in contact for a short distance with the terminal 

 cells of the median series; erect, or tilted slightly inward, straight, 

 somewhat asymmetrical; the outer margin more convex; the tip 

 more or less clearly distinguished, tapering subsymmetrically to the 

 rather blunt truncate apex. Spores about 35 X 3 ii. Perithecia 

 75-85 X 24-27 tx. Antheridia 15 ^l. Appendages 12-20 X 7.5 /x- 

 Total length to tip of perithecium 230-325 X 28 p.. 



On the wing tips of Gryllotalpa sp.. No. 2155, U. S. Nat. Mus. ; 

 Africa, (Mearns). 



Several specimens have been examined ^11 in good condition. The 

 antheridia are similar in type to those of R. Lycopodinae and R. 

 minutus and occur in the same position as in the last mentioned 

 species. The production of one or more secondarj- appendiculate 

 cells from the base of the primary appendage, is unusual. 



Rickia Lycopodinae nov. sp. 



Rather broad distally, tapering below; the hyaline margins con- 

 trasting with the deep black-brown or opaque axis and perithecium. 

 Receptacle triseriate; the foot round, and as large as the thick-walled 

 basal cell, which is distally intruded so as nearly to separate the two 

 basal cells of the marginal series: anterior series consisting of about 

 twelve to fifteen cells, mostly short broad and obliquely superposed;
