thecium united to the lower half of that of the appendage, but other- 

 wise wholly free on both sides; sometimes nearly twice as long as 

 broad, externally slightly concave, prominent below the outer basal 

 cell, which is in contact throughout with the base of the ascigerous 

 cavit}', its apex forming a distinct prominence; the inner long and 

 narrow, ending somewhat lower in a similar prominence and extend- 

 ing down to the stalk-cell. Venter irregular, slightly inflated, the 

 wall-cells ending distally in distinct prominences, and showing a 

 slight twist which involves the neck and tip: the neck relatively stout, 

 slightly curved, hardly distinguished, except by the subtending promi- 

 nences; the tip subtended by slight depressions on either side, its 

 margins convex, abruptly so on the inner side, so that the short apex 

 is subtended by a rather prominent hunch; distal margin of the apex 

 broad, outwardly oblique, and nearly straight, the lip-edges not at all 

 prominent. Spores 40 X 5 jjl. Perithecia 120-135 X 28-32 ;u; the 

 stalk-portion about 68 X 18 (jl. Appendage 75-86 m, the stalk-cell 

 18 X 14 M. Receptacle 112-130 X 18-24 fi. Total length 280-315 m- 



On Borhonis sp. No. 2732, Kamerun, \Y. Africa. 



This species is very closely allied to S. Borbori, although very unlike 

 it in general appearance, and may possibly prove to be an abnormal 

 development of the latter. Apart from its elongate form, the chief 

 difference is found in the appendage, the principal cells of which are 

 longer than broad, instead of the reverse, the basal separating a well 

 marked androphorous cell bearing three superposed antheridia. About 

 a dozen examples have been examined, none of which seem to vary 

 toward S. Borbori. The hosts appear to belong to the same unde- 

 termined species of Borborus. 



Stigmatomyces distortus nov. sp. 



Strongly curved throughout, hyaline becoming tinged with pale 

 yellowish, the venter darker brownish yellow, the appendage dull 

 brownish below. Receptacle very slightly broader at the horizontal 

 septum, the basal somewhat longer than the subbasal cell, slightly 

 narrower above the foot, the subbasal broader distally, slightly con- 

 cave on one or both sides. Stalk-cell of the appendage short, slightly 

 broader distally than the broad insertion, which lies hardly higher 

 than the distal margin of the perithecial stalk-cell. The appendage 

 turned obliquely across the basal cell region; consisting of four persis- 

 tent cells, the two lower relati\'el;y' large, subequal, brownish, termi-
