Laboulbenia spiralis dot. sp. 



Perithecium one half i le third (sometimes only the tip), free 



from the receptacle, dark dull amber-brown with dirty brown suffusions, 

 rather stout, the tip moderately well distinguished, rather short and 

 it, deep black-brown, except the distal hyaline lip-edges. Distal por- 

 tion of tli*- receptacle concolorous with the perithecium; cells 1 and 11 

 much paler; cell 1 longer than cell II. the two forming a rather Blender 

 stalk of about the same diameter throughout, above which the <li-tal 

 portion, of tin- receptacle is Bomewhat abruptly distinguished : the lighter 

 portions marked by fine transverse Btriations not visible in the deeply 

 colored often opaque distal region. Outer appendage consisting of ;i 

 main straight divergent axis formed by usually three nearly equal ce -. 

 deeply blackened externally, bearing distally and from each of their 

 upper inner angles a very long slender erect simple branch which is 

 reddish brown, paler and spirally twisted distally. The inner append- 

 age consisting of a basal cell about as large as that of the outer 

 appendage and hearing on either Bide a branch which may give rise to 

 one or two erect simple hranehlets similar to the branches of the outer 

 appendage. Perithecia about 150 x 55 it. Total length to tip of peri- 

 thecium 300-390 ,<* ; to insertion-cell 275-325 ft. Appendages, long 

 480-610/1. 



On Hexagonia sp. ?, Hope Coll., No. 288, Ceylon (Thwaites). 



Laboulbenia strangulata nov. sp. 



Perithecium one third to one half free, dark brown, concolorous below 

 with the distally almost opaque receptacle; symmetrical. Btraight; the 

 tip undifferentiated, bluntly rounded except for a hyaline flattish ter- 

 minal papilla formed hy the projection of one of the external lip-cells. 

 Receptacle slender, cell I usually basal ly curved, broader at the distal 

 end where it is rather deeply suffused with hrown; cell II much longer, 

 its lower two thirds often distinctly inflated, deep hrown distally, rather 

 abruptly constricted to less than half its greatest diameter, the constricted 

 portion hyaline, the short remaining portion above the constriction 

 becoming deep hrown, concolorous with the upper portion of the recep- 

 tacle. I nseit ion-cell normal as in L. Orectochili, oblique, often concave 

 above, the appendages consisting of an outer and an inner basal cell, the 

 two producing in all from three to six outgrowths as in /.. Orectochili, 



s 'what narrower, hyaline except the first one formed from the outer 



basal cell which is always external to those subsequently formed and is
