decide whether it should be regarded as a variety of the present 

 species or of the last mentioned form, or whether it should perhaps be 

 regarded as specifically distinct. It occurs rather rarely, and is 

 usually very crowded, but does not seem to vary definitely toward 

 either type. 



Stigmatomyces Paralimnae nov. sp. 



Form usually subsigmoid, rather short and stout; the perithecium, 

 above its basal cells, comprising two thirds to three fourths of the 

 total length; yellowish, becoming tinged with amber-brown, except 

 at the base, sometimes with an olivaceous tinge. Basal cell of the 

 receptacle short, stout, subtriangular; subbasal cell broader than 

 long, overlapped more or less on its posterior side, sometimes as much 

 as two thirds or more, by the stalk-cell of the appendage; the latter 

 relatively large and prominently convex externally, about twice as 

 long as broad, distally narrow, persistent, slightly colored: the rest 

 of the appendage hyaline, rather broad, soon collapsing; the antheri- 

 dia obliquely superposed in a single row, the necks with little if any 

 right and left divergence: the basal cell usually producing three 

 antheridia, the subbasal two, the uppermost one; the appendage 

 terminated by two superposed antheridia, and lying flat against the 

 perithecium, or with the antheridia directed outward. Stalk-cell 

 and secondary stalk-cell of the perithecium in oblique contact; the 

 former somewhat larger, its base in contact with the whole or nearly 

 the whole of the upper surface of the subbasal cell ; the two combined 

 broader than long, obliquely separated: the three basal cells above but 

 slightly smaller, forming a short, broad insertion, even slightly broader 

 than the base of the venter; the latter granular, when fully mature, 

 and more deeply suffused; about three times as long as broad, its 

 margins becoming slightly convex; the four wall-cells slightly spiral, 

 making less than a half-turn, variably prominent, typically separated 

 by often indistinct furrows, and usually more or less abruptly individ- 

 ually prominent distally, thus accentuating the abrupt transition to 

 the much narrower neck; distal portion of the perithecium very 

 indistinctly, or not at all, distinguished into neck, tip and apex, except 

 that the neck portion is usually nearly hyaline or paler, while the tip 

 and apex are more distinctly suffused; the whole termination usually 

 more or less strongly curved, slightly inflated near the middle, or 

 tapering slightly from near the base; the lip-cells asymmetrically 

 and variably prominent, sometimes conspicuously papillate, or even
