coming dark smoky brown ; cell V often as large as cell IV, pushing the 

 small subtriaugular unmodified insertion-cell outward so that it may 

 become lateral, with its transverse diameter vertical, cell VII unusually 

 large. Appendages consisting of an outer and an inner basal cell, the 

 two free from one another except at the base, mostly several times as 

 long as broad and overlapping slightly ; the outer bearing an external 

 row of superposed branches, usually seven or eight in number, formed by 

 the successive proliferation of the tip of the basal cell, and separated from 

 it by broadly blackened septa ; the branches successively subdichoto- 

 mously branched several to eight or more times, the basal and sometimes 

 the subbasal cell often producing more than two branchlets (two to four) 

 superposed in a single row. The inner appendage like the outer, the 

 basal cell producing a single similar row of branches fewer (usually two 

 to four) in number, overlapping those of the outer appendage and bear- 

 ing antheridia in gi'oups of from one to eight not characteristically grouped, 

 the venter rather abruptly distinguished from the straight cylindrical 

 purplish neck : the branches of both appendages directed outward, hyaline 

 or distally reddish or purplish, constricted at the lower purplish septa. 

 Perithecia (largest) 230 X 55 /j,; average 170 X 40 ^u. Total length to tip 

 of perithecium very variable, from 275 /^ to 1 mm. Appendages 200- 

 350 |U. Antheridia 16 X 4ju.

Laboulbenia Ortliomi nov. sp. 



Perithecium free, long and straight, slender, sometimes slightly inflated 

 distally, deep clear brown ; the tip broad, prominent, not abruptly differ- 

 entiated ; the lips rather large and prominent, the lower wall-cell as a 

 rule elongated to form a hyaline neck, usually well marked and contrasting 

 with the body of the perithecium. Receptacle shorter than the perithe- 

 cium, olive-brown, except the hyaline or slightly yellowish basal cell. 

 Insertion-cell not as broad as cell IV. The outer appendage consisting of 

 a basal cell longer than broad, blackened externally, producing usually 

 a single simple terminal branch, the two lower cells of which are black- 

 ened externally and sometimes give rise to erect simple branchlets. The 

 inner appendage consisting of a basal cell similar to that of the outer, and 

 producing on either side a straight hyaline erect branch. Spores 50 X
