The short inflated basal cells of the rigid, nearly hyaline para- 

 physes, associated with a definite disk of insertion, distinguish 

 this small species from other forms with which it might possibly 

 be confused. Three specimens only, in good condition, were found 

 growing on the elytra of the host. 



Laboulbenia recta, nov. sp. 



Olivaceous. Perithecia rather small, slightly rounded to the 

 large, almost cylindrical, abruptly truncate, blackened apex, the 

 lips of which may be very slightly oblique inwards. Pseudopara- 

 physes stout, arising from two basal cells, the outer twice as long 

 as the inner, each giving rise to from two to three branches, which 

 may in turn be once or twice branched, all the branches parallel 

 to one another and to the main axis of the receptacle and of the 

 perithecium, which they exceed by more than half its length: disk 

 of insertion thick, black, horizontal, placed opposite the middle 

 of the perithecium. Receptacle normal, rather elongate. Spores 

 75-80 X 6-7 n. Pseudoparaphyses 175 p. Perithecia 150-180 X 

 50-75 ix. Total length to tip of perithecium 380 /x : greatest breadth 

 75-110 M . 



On Platynus extensicolUs, Connecticut. 



A rare species, occurring on the legs of its host in company with 

 L. scelopkila, to which it bears some resemblance in the branching 

 of its paraphyses. A small number of specimens from three locali- 

 ties near New Haven show little variation. 



Laboulbenia contorta, nov. sp. 



More or less suffused with reddish brown. Perithecia suffused 

 with blackish brown, sometimes nearly opaque, considerably in- 

 flated, strongly curved outwardly at the apex, so that the nearly hya- 

 line, very broad, hatchet-shaped lips are almost vertical in position : 

 the whole perithecium at maturity usually so twisted near the base 

 that its axis crosses the pseudoparaphyses obliquely. Pseudopara- 

 physes exceeding the perithecium by about twice its length, aris- 

 ing from two basal cells, the outer twice as large as the inner; the 

 outer pseudoparaphysis simple or once branched above the sub- 

 basal cell, the inner sometimes branched above the basal and sub- 

 basal cells : disk of insertion thick, black, placed about one third of 

 the distance from the base to the apex of the perithecium. Recep- 

 tacle abruptly expanded above cell II., cells I. and II. rather 

 elongate, the rest somewhat reduced and rounded. Spores 75 X 5 /a.
