short, somewhat irregular iu form, distally slightly inflated, with a more 

 or less well-marked external elevation just above the base ; the tip 

 rather abruptly distinguished, relatively narrow, the apex broadly hya- 

 line, with coarse irregularly prominent lips, the lower half black, sub- 

 tended externally by a well-developed, horn-like, blunt-tipped, hyaline 

 outgrowth, which is larger than the whole tip and slightly curved out- 

 ward. Receptacle colorless or pale yellowish, the basal and subbasal 

 cells of about the same diameter throughout, subequal, rather long and 

 slender in contrast to the small, compact distal portion ; cells III and 

 IV subequal, or cell IV larger, the septum between them nearly hori- 

 zontal; cell V triangular, relatively small and, like cell IV, slightly 

 suffused above with brown, below the very broad, thin, clearly defined, 

 black insertion-cell ; the upper hyaline angle of which protrudes between 

 the basal cells of the appendages. A-ppendages similar in type to those 

 of L. Galeritae, hyaline, the outer consisting of about five to seven very 

 obliquely superposed cells, bearing the branches distally and externally ; 

 the basal part of each branch consisting usually of two short brownish 

 inflated or squarish cells, distinguished by constrictions and dark septa, 

 the distal part about equal to the basal in length, or somewhat longer, 

 often unicellular, hyaline, stained reddish in the types, very thick-walled ; 

 abruptly broader, as a rule, than the basal part; the tip bent slightly, 

 tapering or even slightly inflated. The inner appendage similar to the 

 outer, the basal part of the branches usually three-celled, the lowest, and 

 sometimes that next above it, consisting of a single cell which bears 

 terminally a single antheridium, the long neck of which is rather abruptly 

 bent near the middle. Spores 90-110 X 7 jM. Perithecia 175-240 X 

 60-80 ;U. The horn-like projection about 40 X 22 ^u. Receptacle 

 325-475 ju. Greatest total length of appendages 450-600 ^.

Laboulbenia Craspidophori nov. sp. 



Perithecium relatively large, almost wholly free, erect, usually bent 

 slightly inward toward the base and outward toward the tip, becoming 

 almost opaque dark brown ; the tip rather small, hardly distinguished, 

 bent slightly outward; the lip edges pale, outwardly oblique. Recep- 

 tacle usually rather slender, the basal and subbasal cells relatively large 

 and long, faintly suffused with brown, the upper longer, separated from 

 cell III by a narrow horizontal septum and from cell VI by a very 

 oblique or almost vertical one ; the distal portion of the receptacle
