NEW LABOULBENIALES. 655 



pushed to one side by the base of the perithecial stalk, which occupies 

 more than half the distal surface of the basal cell. Stalk-cell of the 

 appendage smoky or purplish brown, much flattened, horizontal, 

 separated by a thick more deeply colored septum from the concolor- 

 ous, nearly symmetrical, bullet-shaped, abruptly apiculate sterile 

 appendage-cell, which is similar to that of the male. Stalk- and basal 

 cells of the perithecium not distinguishable as separate cells, the posi- 

 tion of the latter indicated by one outer and two inner flattish eleva- 

 tions which lie some distance above the ascigerous cell; the bases of 

 the lower (venter) wall-cells indicated by somewhat more distinct 

 rounded elevations; similar, somewhat less prominent protuberances 

 distinguishing the regions of the neck and tip; the region of the venter 

 broad, of uniform width or slightly inflated, the region below it to the 

 base of the stalk, which includes about half the total length, tapering 

 nearly to its insertion, the neck-region slightly tapering, the tip nar- 

 rower, clearly distinguished, hardly tapering, bent slightly inward; 

 the apex well defined, slightly shorter than the tip, somewhat asym- 

 metrical, the base slightly and abruptly spreading, as are the lips also, 

 so that the margins are slightly concave, the two inner lips forming 

 rather prominent blunt tooth like projections, the outer shorter and 

 flattened; the whole perithecium, from the insertion of its stalk upward, 

 clavate-fusiform, elongate, the ascigerous and sporigerous regions 

 tinged with dull purplish brown. Spores 42-Ab X 4 /x. Perithecia, 

 including stalk 210-280 X 36-45 ii, apex and tip 35-40 tx. Basal cell 

 70-90 X 21 ^t; the subbasal 10 X 18 ju. Stalk-cell of the appendage 

 4 X 16/i broad; the appendage-cell 18 X 14 ^i. Total length to tip 

 of perithecium 290-360 y.. 



On the superior abdomen and legs of Strebia vespertilionis Fabr. 

 No. 2073a, M. C. Z., taken on bats in Venezuela (Carriker). 



Stigmatomyces. 



With the exception of the three species, S. AnoiMsckii, S. australis 

 and S. Stilici, no further additions appear to have been made to this 

 genus since the publication of my second Monograph. The form 

 described as S. Italicus by Spegazzini in his second contribution on 

 Italian Laboulbeniales (Ann. d. Mus. Nac. d. Hist. Nat. d. Buenos 

 Aires, 27, 71, Fig. 37) I am quite unable to distinguish from S. Papua- 

 nus, with which he compares it, a widely distributed and variable 

 species.
