Laboulbenia Kudau.k Thaxter. Plate LVIII, figs. 7 8. 



Proc. Am. Acad. Arts and Sci., Vol. XXXVIII, p. 30. June, 1902. 

 Perithecium transparent brown, nearly straight externally, the inner margin somewhat convex; the 

 inner lip-cells deeply suffused, contrasting, coarse, erect, prominent, the lip edges hyaline, outwardly 

 oblique. Receptacle normal, rather short and stout, somewhat prominently rounded below the perithe- 

 cium; cell III smaller than cell VI ; cells IV and V broad, equal in length, prominent below the broad 

 insertion-cell. Outer appendage consisting of from three to four mostly roundish or flattened super- 

 posed cells, constricted at the blackened septa, which become oblique by the proliferation of each cell 

 from its inner side to form a single, usually simple, erect branch; the branches eventually stout, rather 

 closely septate, thick-walled; the basal cell of the inner appendage half as large as that of the outer, 

 producing one or more simple branches similar to those of the outer appendage, and short antheridial 

 branchlets, which bear the brown, slightly curved antheridia in a rather dense group. Spores 72 X 5 fi. 

 Perithecia 150-155 X 55 /t. Receptacle 170-220 //. Appendages 180-225 /i. Total length to tip of 

 perithecium 250-350 fi.

 No. 952. 



The outer appendage is broken in all the types of this species which are not very young, but in the 

 latter the character of the appendage is clearly shown (fig. 8); the primary axis consisting of short inflated 

 cells, each of which is distinguished by a blackened septum and bears a branch from its inner side. The 

 relationships of this species are quite uncertain, but perhaps it may be placed as well near L. Loxandri as 

 elsewhere, although the outer appendage of the latter species is simple.

 Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 183. Dec, 1899. 



Perithecium about three fourths free, suffused with brownish, translucent, the distal half narrow 

 and strongly curved inward, especially at the tip, the latter externally and distally blackened, the lip-edges 

 hyaline. Receptacle rather stout, pale dirty brownish; cell II basallyand distally and cell VI externally 

 more deeply suffused. Cells IV and V elongated so that they become parallel and carry the insertion-cell 

 upward and outward free from the perithecium. Outer appendage consisting of a rounded basal cell 

 bearing a single terminal branch, the basal cell and one or two cells above it rounded, constricted at the 

 mostly blackened septa, simple or each of the lower cells producing distally on the inner side a branchlet, 

 the branchlets and the terminal portion of the main branch hyaline, slender, thin-walled, tapering. Inner 

 appendage consisting of a basal cell like the outer and like it producing a branch on either side. Spores 

 about 45 X 4 /i. Perithecium 140 X 40 /i. Total length to tip of perithecium 340 a; to insertion-cell 

 275 ft. Appendages, longest 120 fi. 



On elytra of Loxandrus unistigma Bates, Brit. Mus. No. G59 (Biologia Coll.), Paso Antonio, Guate- 

 mala. 



A well ntarked species, perhaps allied to L. Chiriquensis, but differing in its appendages and in other 

 important respects. It has been seen only in one instance among the numerous forms of Loxandrus 

 examined. 



Laboulbenia Eg.e Thaxter. Plate LVI, fig. 12. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 173. Dec, 1899. 



Perithecium free or nearly so, slender, usually somewhat curved inward, becoming evenly suffused 

 with pale-olive brown, the broad tip not differentiated from the body of the perithecium, the lip-cells more 

 or less suffused with darker brown. Receptacle pale yellowish, often elongate, the basal cell short; cell 

 II several times as long, becoming amber-brown with transverse striations; cells III and VI about equal, 

 elongate. Insertion-cell not deeply blackened. Outer appendage consisting of a usually somewhat in- 

 flated basal cell with thick outer wall, bearing a branch terminally distinguished by a thin black septum
