THAXTER. — NEW LABOULBENIACEAE. 37 



ceptacle normal, rather short and stout, somewhat prominently rounded 

 below the perilhecium ; cell III smaller than cell VI ; cells IV and V 

 broad, equal in length, prominent below the broad insertion-cell. Outer 

 appendage consisting of from three to four mostly roundish or flattened 

 superposed cells, constricted at the blackened septa, which become oblique 

 by the proliferation of each cell from its inner side to form a single, 

 usually simple, erect branch ; the branches eventually stout, rather 

 closely septate, thick-walled ; the basal cell of the inner appendage 

 half as large as that of the outer, producing one or more simple 

 branches similar to those of the outer appendage, and short anthe- 

 ridial branchlets, which bear the brown, slightly curved antheridia in a 

 rather dense group. Spores 72 X 5 ju. Perithecia 150-155 X 55 ^u. 

 Receptacle 170-220 n. Appendages 180-225 ^. Total length to tip of 

 perithecium 250-350 /x.

 and legs ; Berlin Museum, No. 952. 



Laboulbenia exigua nov. sp. 



Perithecium relatively very small, the upper third or less free, reddish 

 brown, deeper than the receptacle, erect, straight, nearly symmetrical ; 

 the tip clearly and rather abruptly distinguished; the lip-cells with 

 darker shades, distinctly spreading, especially externally, the edges 

 hyaline, nearly horizontal. Basal and subbasal cells of the receptacle 

 subequal, small. The insertion-cell broad, well marked. The basal 

 cells of the appendage clearly distinguished, subequal, about as broad as 

 long; the outer bearing a single, simple erect branch, the basal cell of 

 which is abruptly narrower, squarish, deeper brown, the septa dark, the 

 rest of the branch simple, obscurely septate, distally hyaline, tinged with 

 pale brown below ; the inner appendage like the outer, shorter, paler,^ 

 the brownish short basal portion of the single simple branch smaller and 

 without septa. Spores about 40 X 4 ju. Perithecia 86 X 26 (i. Re- 

 ceptacle 220 |u. Appendages 184-150 /x. Total length to tip of peri- 

 thecium 250-290 /x.

Laboulbenia flaccida nov. sp. 



Perithecium free except at its base, brown, straight, slightly inflated 

 below, tapering gradually to the broad blunt apex; the tip scarcely if at 

 all distinguished, marked by darker shades ; the lips coarse, not promi-
