of various species and from widely different localities, as well as of forms of the same general type which 

 occur on allied hosts, renders any definite decision as to the limits of this species a mailer of great diffi- 

 culty. The Hast Indian forms approach very closely indeed to />. //agr/lala, though they retain the color- 

 ation of the type, and the slightly individual perithecial tip. The basal cell of the outer appendage is 

 either not at all or very inconspicuously inflated, and one form from the Philippines can hardly be dis- 

 tinguished from typical L. flagellata. On other American hosts, however, the inflation of the basal cell 

 becomes even more pronounced than it is in the typo, the coloration changes, and on species of Inn, Pina- 

 codera, Cymindis, Euproctus, Aperies and Callida a form occurs w hich, w ithout comparison, I should not 

 have hesitated to separate specifically. Such a separation may eventually prove desirable, yet I have 

 thought it best to group all these forms under the present name until they can be more carefully revised 

 and illustrated. The material thus grouped has been obtained from the following hosts. British Museum ;

Laboulbenia Hawaiiensis Thaxter. Plate LVII, figs. 1-3. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXVIII, p. 40. June, 1902. 



Perithecium variously suffused with dark olive brown, sometimes transparent brownish yellow, 

 becoming nearly opaque, about one quarter, or only the tip, free from the receptacle, rather short and 

 stout; the tip black, often bent outward, tapering rather abruptly; the lip-edges hyaline, rather promi- 

 nent and outwardly oblique. Receptacle pale reddish amber or yellowish, becoming variously suffused 

 with dark olive-brown, especially distally; the basal cell more commonly narrow and hyaline below; 

 abruptly broader and suffused with dark olive-brown below the base of cell II, which is often abruptly 

 broader through a slight inflation in this region, and similarly suffused, the suffusions often faint; cells 

 III to V often deeply suffused with olive-brown, faintly striate ; cells III and IV subequal ; cell V extending 

 more or less prominently upward along the inner margin of the perithecium which is further bordered 

 by cells III and IV; the insertion-cell carried obliquely outward by these modifications. Basal cell of 

 the outer appendage usually hyaline, bearing normally two branches; the basal cell of the inner hyaline, 

 that of the outer often small and blackened, bearing two branchlets; the outer shorter, more slender, 

 opaque (usually broken) ; the basal cell of the inner appendage similar to that of the outer, often pro- 

 truding somewhat inward, bearing two branches like the outer, or less often laterally, that next the peri- 

 thecium bearing one or more antheridial branchlets; the antheridia terminal in groups of two or more, 

 sometimes densely clustered; the other bearing similar antheridial branchlets or more often one or more 

 long sterile branchlets like the outer appendage; all the sterile branches usually elongated in a sweeping 

 curve toward the perithecium, commonly rich brown or nearly opaque, sometimes hyaline, sometimes 

 multiplied by branching close to the base. Spores 65 X 5 y. Perithecia 90-125 X 40-55 y. Receptacle 

 200-335 y. Appendages 290-725 y. Total length to tip of perithecium 230-360 y.
