 several times branched, the branches or branchlcts commonly more or less marked by basal blackish suf- 

 fusions, divaricate, slender, tapering, flexuous. On Chlwnius sp., Sandakan, Borneo; British Museum,

Laboulbenia Craspidophori Thaxter. Plate LIII, figs. 8-9. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXVIII, p. 32. June, 1902. 



Perithecium relatively large, almost wholly free, erect, usually bent slightly inward toward the base 

 and outward toward the tip, becoming almost opaque dark brown; the tip rather small, hardly distin- 

 guished, bent slightly outward; the lip edges pale, outwardly oblique. Receptacle usually rather slender, 

 the basal and subbasal cells relatively large and long, faintly suffused with brown, the upper longer, 

 separated from cell III by a narrow horizontal septum and from cell VI by a very oblique or almost verti- 

 cal one; the distal portion of the receptacle narrow, but rather abruptly distinguished, especially cells 

 III and IV, more or less deeply suffused, becoming concolorous with the perithecium. Outer appendage 

 long, slender, simple, or rarely distally furcate, curved outward; the basal cell of the inner appendage 

 relatively very small, bearing a single, erect, short, one-celled branch; which, after bearing several an- 

 theridia distally, soon disappears. Spores 75 X 5 /i. Perithecia 180-210 X 48 /«. Receptacle 150- 

 325 p.. Appendages longer, 300-375 ft. Total length to tip of perithecium 280-500 a.

This form is allied to L. prolifcrans, and although from a description alone it might be readily con- 

 fused with other species in which the outer appendage is single and simple, its characters show sufficient 

 individuality to separate it readily from any other species thus far described. It might be regarded as 

 representing the original simple type from which L. prolifcrans and its varieties have come, and it, more- 

 over, occurs on similar hosts. Its individuality is perhaps best illustrated by the outline of its perithecium 

 which resembles that of L. prolifcrans. The tip is not, however, distinguished as in this species, and none 

 of the individuals thus far examined have shown any tendency to proliferation in cell V. 



Laboulbenia exigua Thaxter. Plate LIII, fig. 1. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXVIII, p. 37. June, 1902. 

 Perithecium relatively very small, the upper third or less free, reddish brown, deeper than the recep- 

 tacle, erect, straight, nearly symmetrical; the tip clearly and rather abruptly distinguished; the lip-cells 

 with darker shades, distinctly spreading, especially externally, the edges hyaline, nearly horizontal. Basal 

 and subbasal cells of the receptacle subequal small. The insertion-cell broad, well marked. The basal 

 cells of the appendage clearly distinguished, subequal, about as broad as long; the outer bearing a single, 

 simple erect branch, the basal cell of which is abruptly narrower, squarish, deeper brown, the septa dark, 

 the rest of the branch simple, obscurely septate, distally hyaline, tinged with pale brown below; the inner 

 appendage like the outer, shorter, paler, the brownish short basal portion of the single simple branch 

 smaller and without septa. Spores about 40 X 4 ji. Perithecia 86 X 20 ft. Receptacle 220 /t. Append- 

 ages 184-150 /i. Total length to tip of perithecium 250-290 /x.
