On Mesothriseus tricolor Sharp, Molokai, No. 1239; M. collaris Sharp, 

 No. 1240, Molokai; on No. 1235, Maui, and No. 1260, Oahu, in Perkins 

 Collection. 



Var. spectabilis nov. var. Perithecium large, long, tapering more or 

 less symmetrically above and below, strongly curved (or often recurved) 

 outward throughout its length, including the clearly distinguished hyaline 

 neck; dark olive brown, becoming nearly opaqu3, the black tip slightly 

 distinguished, the lip-edges hyaline. Receptacle as in the type. Ap- 

 pendages as in the type, but one or both of the primary branches of the 

 inner appendage hyaline, contrasting, many celled, and variably elongated 

 through continued terminal proliferation, black branchlets arising one from 

 each successive cell and alternating on opposite sides of the primary branch, 

 often very long, curved upward and inward so as to cross one another, 

 when two primary branches are present, with such regularity as often to. 

 form a lattice-work pattern ; the series often complicated by the produc- 

 tion of copious slender hyaline branchlets from the upper side of the 

 stjcondary branches. Perithecia, main body, 165-200 X 40-48. Total 

 length of appendages 290-360 ^u.

Laboulbenia Columbiana nov. sp. 



Uniform amber yellow. Perithecium straight, free, converging ab- 

 ruptly from the base toward the appendages at an angle of about 45°, 

 slightly and nearly symmetrically inflated, the tip relatively broad, with 

 darker subterminal suffusions ; the lip-cells somewhat spreading, the pos- 

 terior and two lateral ones forming distinct ear-like lateral horizontal 

 prolongations. Receptacle normal, tapering to the pointed foot, the 

 basal and subbasal cells relatively large, the latter largest, cells IV and 

 VI subequal ; cell V separated obliquely from cell III, and somewhat 

 lonf^er than cell IV, which is separated by a horizontal septum. Inser- 

 tion-cell thick, somewhat translucent, purplish. Outer appendage simple, 

 short; the basal cell faintly purplish, more or less abruptly convex exter- 

 nally, separated by a constriction and dark septum from the subbasal 

 cell, which is al-o distinguished above by a dark septum, basal cell of 

 the inner appendage smaller than that of the outer, bearing a simple
