NEW LAHOULHKNIALKS. 231 



erect, tapering-, short, its basal cell slightly longer tiian broad; the 

 subbasal abruptly narrower, distinguished above and below by black- 

 ened septa, the lower oblique; the distal part consisting of one or two 

 cells, hardly exceeding the middle ol" the peritheciuni: basal cell of 

 the inner appendage but slightly smaller, bearing a short simple 

 hyaline branch on either side, erect and appressed, without dark 

 septa. Spores about 25 X 3 )U. Peritheciuni 65-70 X 24-2S fx. Ap- 

 pendages 28-35 ijl. Total length lOS-112 /j., to insertion cell 42 fj.. 



On the posterior legs of Bcmbldium sp. Bahos de Apoquindo, Chile. 



A minute and simple species distinguished by its olivaceous color, 

 stout form, large pale basal and smaller narrower subbasal cell, and 

 the black septa of its short simple outer appendage. The rather 

 clearh- defined walls have a more or less distinct reddish tint. 



Coreomyces subdivisus nov. sp. 



Uniformly pale brownish yellow throughout; straight, or but 

 slightly bent; the peritheciuni almost exactly half the total length. 

 Of the three basal cells, the subbasal, only, is usually slightly longer 

 than broad; the third surmounted by from two to four flattened 

 cladophorous cells, more often two, which are in turn followed by a 

 large somewhat flattened cell, surmounted by two more cladophorous 

 cells which subtend the perithecium; which is rather stout, erect, 

 hardly inflated, the distal third or fourth curved outwards and side- 

 wise, the stout bluntly and irregularly rounded apex being rather 

 abruptly bent. Appendages copious, or usually broken off, rather 

 stout, rigid, somewhat divergent, once or twice branched, the tips 

 slightly tapering. Perithecium 80-88 X 28-30 /x. Total length 150- 

 175 ju. Appendages, longest 125 ijl. 



On the mid inferior abdomen of Corisa sp. No. 1449, Concepcioh, 

 Chile. 



This species appears to grow only on the middle of the inferior 

 surface of the abdomen. It resembles C. Corisae in general appear- 

 ance, but appears to be constantly distinguished by its smaller size, 

 paler color, and the presence of cladophorous cells immediately below 

 the perithecium as well as in the normal position. 



Coreomyces acuminatus nov. sp. 



Habit rather slender, subsigmoid, the axis consisting of three cells 

 above which three to seven flattened cladophorous cells are dis-
