THAXTER. — NEW LABOULBENIACEAE. 27 



venter of the short, stout, short-necked antheridia : the upper tier 

 relatively large, more or less crescent-shaped according to the degree of 

 lateral development, edged externally with blackish brown, more broadly 

 below, the brown area punctate ; the cells about thirty-one in the larger 

 individuals, the marginal ones forming a rather slender series, which 

 may curve abruptly upward nearly to the middle of the perithecia, or 

 assume a more divergent habit ; the perithecigerous area horizontal, pro- 

 ducing normally four perithecia, three appendages arising between the 

 two middle ones and one between each of the others, the external cells 

 bearing appendages as usual which vary in length. Perithecia rather 

 long and slender, hyaline or faintly yellowish brown, conspicuously 

 tinged with purplish brown below the perfectly hyaline tip, the anterior 

 lip-cells forming a pointed projection, the posterior ones forming each a 

 relatively large ear-like appendage which tapers to a pointed apex, and 

 is slightly curved, the two diverging from one another at an angle of 

 about 50°. Spores about 38 X 2.5 fi. Perithecium without appendages 

 126 X 25/i; the appendages 14/i,. Receptacle 220-350 X 120-lG5|u.. 

 Total length to tip of perithecium 300-330 ix. Appendages 20-80 /x.

Dichomyces Belonuchi nov. sp. 



Receptacle relatively large and long : the distal tier relatively small, 

 consisting of from eleven to thirteen short cells, slightly suffused, the 

 median cells little longer than the rest, the series forming slight, rounded, 

 sometimes almost obsolete lateral projections on either side of the peri- 

 thecia : the basal cell small, partly transparent : the lower and middle 

 tiers not distinguished, uniformly opaque ; a portion of the middle cell, 

 and sometimes the tips of other cells in the middle tier, more or less 

 translucent, the marginal cells ending in a slight rounded prominence 

 below the base of the antheridiura. Perithecia normally two, evenly 

 suffused with pale reddish brown, rather long and slender, tapering 

 throughout, the conformation of the lip-cells much as in D. furciferus. 

 Spores about 30x3/x. Perithecia 75-80 X 18-20 /x. Receptacle 

 108-126 X 54-58 ju. Total length to tips of perithecia 185-200 ^a.
