superposed cells all of which, except the two or three basal ones and the terminal one, function as antheri- 

 dial cells, opening by short necks superposed in a single series. 



This genus is made for the reception of a single species formerly placed in Teratotti i/ees, from which 

 it differs in the character of its appendages, both sterile and fertile; the latter resembling more nearly 

 those of Covet hvoinyce.i by reason of the serial arrangement of its intercalary anthcridial cells. The two 

 or three sterile basal cells of this appendage are usually rather definitely distinguished by a slight constric- 

 tion from the appcndiculate cell, and the anthcridial cells appear to be formed through successive divi- 

 sions of a terminal cell which surmounts the series at maturity and is not functional. It is evident that 

 the genus is closely related to Teratomyees, between which and Corethromyees it seems, on account of the 

 structure of its anthcridial appendages, to form a connecting link. The anthcridial appendages also recall 

 those of Stiymatomyces, but are of a different type, since the successive cells which compose them and are 

 assumed to be anthcridial cells, are absolutely intercalary and do not cut off a basal cell.

Perithecia one to three in number, usually symmetrical and straight, becoming clear purplish brown, 

 often considerably inflated below and conical above; the tip blunt or sometimes slightly pointed, the 

 basal cells variously elongated sometimes nearly as long as the perithecium proper and often longer than 

 the usually well developed stalk-cell. Receptacle symmetrical, its basal cell nearly hyaline, the cell above 

 it tinged with reddish brown and somewhat larger, the third cell like the subbasal, squarish and some- 

 what larger. Appendages nearly hyaline or suffused, never deeply, with reddish brown, comparatively 

 few in number, rather stout and long in general, curved beak-like cells sometimes borne on short peri- 

 pheral appendages; all the appendages, or their primary branches, distinguished by a blackish brown 

 basal septum, some, often many of them distinguished by being closely septate above, the cells thus formed 

 (the antheridia V) producing a series of lateral outgrowths projecting obliquely upward and superposed. 

 Perithecia 140-200 X 45-60 /(, their basal cells 40-120 fi, the stalk-cell 35-126 X 25 ft. Receptacle to 

 base of appendages 70-100 ji. Appendages (longest) 175 y. Total length to tip of perithecium 325- 

 450 ix.

It is evident from the hosts and localities above enumerated that this species is widely distributed, 

 although 1 have never had an opportunity to examine it in a fresh condition and have thus been unable 

 absolutely to observe any discharge from the antheridia. The appendages appear to be very easily broken 

 and are not in good condition in a majority of.the specimens examined. A few that are comparatively 

 young possess short peripheral appendages which, as in Teratomyees, are terminated by the beak-like cell 

 characteristic of this genus. It is very doubtful if the record on PhUonthus is reliable.

Several notable additions are made to this well marked type which is a very constant one, as the 

 genus is now restricted by the exclusion of Sympleefromyers vulgaris. One additional form is known to 

 exist, which was found on a species of Acylopliorus in the British Museum, No. 394, from Tasmania, and
