Laboulbenia cristatella nov. sp. 



Hyaline, becoming suffused with olivaceous brown. Receptacle 

 small; cell I larger than cell II, which is somewhat roundish, its 

 margins more or less convex; cells III + IV much smaller than cell 

 II; cell V small and narrow, often partly free above; cell VI small, 

 flattened, and oblique. Insertion-cell narrow, opaque, indistinguish- 

 able from the basal cell of the outer appendage. Basal cell of the 

 outer appendage black below and externally, broad and quite hyaline 

 above, bearing externally and distally a series of branches radially 

 placed; the outer (lowest) branch furcate, its basal cell obliquely 

 hyaline within, externally black, the two branchlets broadly blackened 

 externally, except distally, the outer wholly so at the base; the re- 

 maining branches always simple, stout, usually tapering somewhat 

 toward the base and apex, broadly blackened externally, except 

 distally; usually curved toward and beyond the perithecium, forming 

 a crest-like series which exceeds the latter in length: basal cell of the 

 inner appendage very small, brown, bearing a short simple branch 

 on either side both two-celled, the lower cell deeply suffused, the upper 

 hyaline, separated from it by a dark septum and bearing usually a 

 pair of relatively large long antheridia, sometimes only one. Peri- 

 thecium not quite free, straight, becoming dark olive brown, very 

 slightly inflated; the tip broad, well distinguished, blackened distally, 

 especially on the inner side; the apex with broad, rounded, rather 

 prominent lip-cells slightly oblique inward; the outer hyaline, the 

 inner deeply blackened, except the narrowly hyaline papillate promi- 

 nent edge. Perithecia 60-76 X 18-22 ft. Receptacle 50-64 X 22- 

 28 m- Appendages longest 125 /x- .Total length to tip of perithecium
