Uniform amber-yellow. Perithecium straight, free, converging abruptly from the base toward the 
ap|>endages 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 posterior 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 longer than cell IV, which is separated by a horizontal 
septum. Insertion-cell thick, somewhat translucent, purplish. Outer appendage simple, short; the 
basal eel! faintly purplish, more or less abruptly convex externally, separated by a constriction and dark 
eptum from the subbasal cell, which is also distinguished above by a dark septum, basal cell of the inner 
appendage smaller than that of the outer, bearing a simple short erect branch on either side. Spores 50

or not it should be considered a mere variety. It is not impossible that the type form on spines owes its 
short habit and small size to less abundant nutrition, but the two may prove distinct. 
Laboulbenia Philonthi Thaxter. 
This species appears to be strictly American, and nothing resembling it, except perhaps L. Bledii, 
occurs on other staphylinids. Additional material has been obtained as follows: British Museum; No.
