Laboulbenia spiralis nov. sp. 



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

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

 rather stout, the tip moderately well distiui>uished, rather short and 

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

 tion of the receptacle concolorous with the perithecium; cells I and II 

 much paler ; cell I longer than cell II, the two forming a rather slender 

 stalk of about the same diameter throughout, above which the distal 

 portion of the receptacle is somewhat abruptly distinguished ; the lighter 

 portions marked by fine transverse striations not visible in the deeply 

 colored often opaque distal region. Outer appendage consisting of a 

 main straight divergent axis formed by usually three nearly equal cells, 

 deeply blackened externally, bearing distally and from each of their 

 upper inner angles a very long slender ei-ect 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 bearing on either side a branch which may give rise to 

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

 appendage. Perithecia about 150 X 55 ^i. Total length to tip of peri- 

 thecium 300-390 fj, ; to insertion-cell 275-325 fi. Appendages, longest 

 480-GlO fi. 



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 recejitacle ; symmetrical, straight ; the 

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

 minal 2^apilla formed by the projection of one of the external lip-cells. 

 Receptacle slender, cell I usually basally curved, broader at the distal 

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

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

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

 portion hyaline, the short remaining portion above the constriction 

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

 tacle. Insertion-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 L. Orectochili, 

 somewhat narrower, hyaline except the first one formed from the outer 

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