THAXTER. — NEW LABOULBENIACEAE. 31 



short erect branch on either side. Spores 50 X 4 p. Perithecia 

 20-25x90-110^. Receptacle 150 X 30 ju. Appendages 40 p. Total 

 length to tip of perithecium 200-250 fi. 



On bristle-like hairs on the elytra of Anchonoderus concinnus Reiche, 

 Columbia; Berlin Museum, No. 1023. A single specimen 680 ft long, 

 with a free perithecium curved outward, with only lateral lip-like pro- 

 jections and with appendages 300 [i in length which are otherwise exactly 

 like those of the type, was found on the same host ; but in the absence 

 of further material it is impossible to determine whether or not it should 

 be considered a mere variety. 



Laboulbenia concinna nov. sp. 



Perithecium opaque, nearly symmetrical, rather long and slender, 

 straight, the lower half slightly inflated ; tapering very gradually distally 

 to the broad, truncate often symmetrical tip, which is barely differenti- 

 ated above an inconspicuous elevation ; the flat lip-edges slightly trans- 

 lucent brown : the basal cells forming a well distinguished short hyaline 

 stalk, the curvature of which bends the perithecium away from the 

 appendages at an angle of nearly 45°. Appendages forming a dense 

 rather short slightly spreading tuft, the axis of which is coincident with 

 that of the receptacle, copiously branched, the branchlets unilaterally 

 disposed, rather closely septate ; the septa mostly dark brown, except 

 the very numerous paler slightly tapering extremities, which hardly 

 reach the middle of the perithecium. Receptacle subclavate, the basal 

 cell rather large, hyaline, narrower below ; the cells above yellowish 

 brown, inconspicuously punctate ; cells III and IV bulging symmetri- 

 cally and prominently below the well-defined insertion-cells ; cells IV 

 and V separated by a nearly vertical septum. Perithecia, exclusive of 

 stalk, 15-180 X 33-45 p, stalk 25 X 30 /j. Receptacle 150-185 X 55- 

 65 p. Appendages (longest) 125^. Total length to tip of perithecium 

 325-375 ii. 



On upper surface of abdomen, at^tip, of Gasnonia sp., Buitenzorg, 

 Java. On a single specimen among numerous hosts kindly communicated 

 by Prof. H. M. Richards. 



Laboulbenia corniculata nov. sp. 



Hyaline becoming pale yellowish. Perithecium becoming tinged with 

 brown, usually bent inward at the base at an angle to the axis of the 

 perithecium, sometimes horizontal (the appendages and their insertion 

 undergoing a corresponding change in position), relatively stout and
