tion-cell is turned obliquely toward the tip of the perithecium : cells 

 VI and the basal cells of the receptacle more or less tinged with olive- 

 brown forming an elevation so that the perithecium appears indented 

 below, all the cells except cell T marked by fine transverse striations. 

 Outer appendage simple, the basal cell rather large, often externally 

 indented near the base, the second and third cells nearly equal, nari'ower 

 than the basal cell and the cells immediately above them; the rest of the 

 appendage tapering to the hyaline attenuated elongate distal portion ; the 

 inner appendage consisting of a basal cell one third as large as that of 

 the outer and bearing a single branch on either side, one or both of 

 which may be elongate much like the outer appendage, bearing one or two 

 short slender antheridial branches near the base which are bent rather 

 abrujitly upward from their point of origin ; the branches all distally 

 hyaline and attenuated ; the basal cells faintly reddish. Ferithecia, 

 average 110 X 37 /t. Total length to tip of perithecium 260-280 /j.; to 

 insertion-cell 250-275 fi ; greatest width 75 fj.. Appendages, longest 

 375 ,x. 



On PericaUus cceruleovirens Tat., Brit. Mus. No. 570, Singapore. At 

 base of posterior legs. 



Laboulbenia melanaria nov. sp. 



Perithecium nearly free, uniformly suffused with clear blackish brown, 

 straight or bent slightly outward ; the tip more deeply colored, the lip- 

 edges hyaline, contrasting, externally oblique. Receptacle hyaline 

 becoming yellowish, often suffused with blackish brown except the lower 

 portions of cells I, III, and VI, and usually cell V. Outer appendage 

 consisting of a basal cell mostly free, bearing terminally a single branch 

 typically once branched above its basal cell, the branchlets elongate, 

 thick-walled, rigid, more or less tinged with brown. The inner append- 

 age consisting of a much smaller basal cell, producing either a short 

 two-celled branch with one or two terminal antheridia, or two longer 

 branches which may be once branched ; the branches like those of the 

 outer appendage but shorter. Perithecium 120 X 35 \i. Total length 

 to tip of perithecium 275 /x ; to insertion-cell 150 /x. Apj^endages, 

 longest, 550 /u.
