 specimens the two lower tiers may be but Blightly developed, bearing 

 neither appendages nor perithecia, the middle producing one antheridium, 

 the number of cells and appendages on one side of the perithecium being 

 as in all case.-, greater than on the other. 



LIMNAIOMYCES nov. genus. 



Receptacle consisting of two portions, a basal pari below the perithe- 

 cium and a distal part united to its posterior margin ; the basal portion 

 consisting of a single basal cell, surmounted by two tiers of cells (some- 

 what as in Peyritschiella), the anterior cell of the upper tier giving rise 

 to a compound antheridium in structure similar to that of Peyritschiella: 

 the distal (marginal) portion consisting of an inner and an outer elon- 

 gated cell, the inner terminating in one of the bell-shaped appendiculate 

 cells characteristic of Chitonomyces, separated from the simple appendage 

 by a broad, constricted, blackened septum; the outer l>y successive sub- 

 terminal external proliferations forming a Beries of cells from which a 

 smaller secondary appendiculate cell is separated above, the whole cor- 

 responding in development to the external portions of the tiers of cells 

 in Dichomyces, the proliferation taking place to the right and left 8UO 

 sively, so that the appendages appear to arise in two rows. 



A clearly defined genus apparently intermediate between Peyritschiella 

 and Chitonomyces. 



Limnaiomyces Tropisterni nov. sp. 



Perithecium amber brown, straight, erect, with a slight nearly median 

 inflation or tapering but very Blightly to the undifferentiated tip; the 



upper half tree. Receptacle pale straw colored, distally dull amber 



brownish, the foot minute. Mack; the basal Cell short and small, the 

 lower tier consisting of tWO cells which are Dearly equal, several times
