EXTRA-AMERICAN LABOLLBEXIALES. 727 



the tip distinguished by a slight indentation, and subtended on the 

 conca^•e side by a stout, bhint, irregular, tapering outgrowth from one 

 of the neck wall-cells; the apex hardly distinguished, short, blunt 

 bent slightly upward, one of the lip-cells prolonged to form a well 

 developed stout, terminal appendage of nearly uniform diameter, 

 slightly geniculate at its base, and distally roundish-truncate. Spores 

 32 X 3.5 m. Perithecia 110 X 35 m; its stalk-portion 38X17//; 

 its terminal appendage 20 X S/i; the lateral one 18 X 14 /z at base. 

 Receptacle 45-50 X 15 m- Appendage in young individuals about 

 40 X 9 M. 



On the wings of Borhorus sp., or a genus closely allied. No. 2732, 

 Kamerun, ^Yest Africa. 



This species is quite unique, owing not only to the fact that it is 

 abruptly bent upon itself, but to the presence of two outgrowths 

 from the perithecium. Three fully mature individuals have been 

 examined and numerous younger specimens. 



Stigmatomyces divaricatus nov. sp. 



Rather long and slender with irregular outline, nearly hyaline, the 

 appendage and the perithecium, with its stalk, almost symmetrically 

 divergent at somewhat more than a right angle from the receptacle; 

 which is usually more or less uniform in diameter, broader at the 

 septum, the basal cell sometimes hardly half as long as the subbasal, 

 usually rather strongly curved below. Stalk-cell of the perithecium 

 relatively short, the base broad, somewhat oblique, the distal half 

 free, broader and usually symmetrically convex; the appendage 

 consisting of about six cells; the basal pale yellowish brown, some- 

 times twice or even three times as long as broad, and of uniform diam- 

 eter, or somewhat broader distally: the three following cells similar, 

 but successively considerably smaller, separated by constrictions: 

 the narrow subbasal cell twice as long as broad; usually slightly 

 concave externally ; the one or two small distal cells somewhat irregu- 

 lar, the uppermost sterile: the basal and subbasal cells bearing each 

 three, the third and fourth each two, antheridia; those above the 

 basal cell subtended by a rounded cell which occupies almost the total 

 diameter of the axis; the fifth cell followed by two small abortive 

 antheridia which separate it from a small sterile terminal cell; the 

 antheridia relatively rather small, directed inward and to the right, 

 their necks somewhat irregularly divergent. Stalk-cell of the peri-
