Laboulbenia Serrimarginis nov. sp. 



Perithecium about three fourths free, dull olive-brown, the outer 

 margin nearly straight, the inner bent rather abruptly below the tip ; 

 the latter not abruptly distinguished, broad, blunt, the lips not well de- 

 fined, dull blackish. Receptacle dull olive-brown, except the almost hya- 

 line rather slender basal cell ; the rest of the receptacle short and stout, 

 concolorous with the perithecium, cell VI broad aud extending down to 

 cell I beside cell II, cell VII extending half way down cell VI exter- 

 nally, the septa of cells III aud IV oblique; cell III extending up to the 

 base of cell V. Appendages as in L. metadata, stouter, brown, darker or 

 blackish toward the base. Perithecia 186 X 50 /x. Total length to tip 

 of perithecium about 300 /.i ; to insertion-cell 190 /a; greatest width 85 p. 

 Appendages 260 <u.

Laboulbenia speciosa nov. sp. 



Perithecium free, long and narrow, the inner half or less hyaline, the 

 outer dark clear blackish brown ; the basal wall-cells forming a short 

 hyaline stalk narrower than the ascigerous portion ; the tip hardly dis- 

 tinguished, bluntly rounded, slightly oblique outwardly, black, hyaline 

 about the pore. Receptacle very elongate, hyaline except cells IV and 

 V which are tinged with amber-color and indistinctly punctate, as is cell 

 III; cell II very elongate. Insertion-cell black, just free from the stalk 

 of the perithecium through the slight enlargement of cell V. Outer 

 appendage consisting of a series (in the unique type) of eight cells super- 

 posed not very obliquely, the basal one larger tinged with brown below, 

 the rest hyaline ; all the cells producing externally a single simple 

 branch, the lower three cells of which are mostly not longer than broad, 

 constricted at the black septa, distally faintly brownish yellow ; the 

 inner appendage consisting of a basal cell which bears on either side a 

 series of four cells like that of the outer appendage, and bearing similar 

 branches in a similar fashion, the three series quite distinct from one 

 another. Perithecium, including its short neck, 280 X 55 p. Total 

 length to tip of perithecium 925^; to insertion-cell 650 p. Appeud- 

 ages about 200 (-250) {*.
