MONOGRAPH OF THE LABOULBENIACE^E. 



297 



Spores fusiform, aseptato, containing several large oil globules, about 37 x 6 (m. Perithecia, 

 100 x 30-33 p. Total length, 130-138 p. 



On Falagria dissecta Er., Waverly, Mass., and Kittery Point, Maine. 



This species is by no means uncommon on the lower surface of the abdomen, where its large 

 projecting perithecia are readily seen at maturity. It also occurs on the upper surface of the 

 thorax and head and more rarely on the legs and the upper surface of the abdomen. It is sub- 

 ject to little variation, figs. 17 and 18 representing almost the extremes of size ; although 

 forms sometimes occur slightly larger than that represented in fig. 17. 



Amorphomyces floridanus Thaxter. Plate V, fig. 30. 



Proc. Am. Acad. Arts and Sci. Vol. XXVIII, p. 159. 



Receptacle consisting of a basal cell, partly divided, from which arises on one side (corre- 

 sponding to the ascigerous side of the perithecium) a somewhat indurated projection which 

 extends upward nearly to the base of the perithecium. Perithecium very large, externally 

 rounded and tapering considerably to the blunt apex, the basal cells, one of which is as large as 

 the rest of the receptacle, forming a short stalk. Spores once-septate about 30 x 5 Perithe- 

 cium, 150 x 52 \x. Receptacle (including stalk-cells of perithecium) 62 y. long. 



On BlediuH basalis Lee, Florida. 



Two specimens of this species were found on the abdomen of a single specimen of its host in 

 the Le Conte collection of Staphylinidae. As above stated it is almost certainly not an Amor- 

 phomyces ; yet since the material is not sufficient to form the basis of a new generic diagnosis 

 in the absence of a knowledge of the male sexual organs, it is here retained under the original 

 name until further information can be obtained concerning it. It differs from Amorphomyces 

 in having what appears to be a two-celled receptacle, the sub-basal cell very small and producing 

 on one side a free projection (seen at the right in fig. 30), which is probably an antheridium ; 

 whether simple or compound can hardly be determined definitely ; while from the other side 

 rises the stalked perithecium, which is larger in proportion to the remainder of the plant than 

 in any other known form. The spores are distinctly once-septate, as seen within the perithecium, 

 and the large ascogenic cell appears to be solitary. 



HELMINTHOPHANA Peyritsch. Plate VIII, fig. 10 (after Peyritsch). 



Sitz. d. Wien. Acad. LXVIII, p. 250 (1873) ; Arthrorhynchus Kolenati, Wiener Entomol. Monatschrift, I (1857), p. 66. 



" Ein gestreckter gegliederter, mit spitzigen Fortsatzen versehener Zweig, scheinbar seitlich 

 zwischen 1. und 2. Tragerzelle des Peritheciums inserirt ; Perithecium mit einem Bauch- und 

 Halstheil versehen, der Porus desselben wird von einem mehrlappigen Kronchen umgeben." 

 (Peyritsch 1. c.) 



This genus, of which I have seen no specimens, appears to be clearly separated from the 

 allied Stigmatomyces through the presence of four instead of one vertical row of antheridial 

 cells in its appendage. As far as can be determined from the figures, the appendage and the
