THAXTEU. — NEW LABOULBENIACEAE, 27 



cells of the series, both laterally and terminally. Stalk-cell of the peri- 

 thecium short, not distinguished from the basal cells ; the body of the 

 perithecium oblong or oval, tapering abruptly distally to form the slender 

 well-distinguished tip, which tapers slightly to the blunt unmodified 

 apex. Spores 25 X 3 /x. Perithecia 55-G5 X 22-28 ju. Appendage 

 including branches 75-100 /x. Receptacle 25-140 X 7-12 fi. Total 

 length to tip of perithecium 100-220 /:i.

 N. H., August, 1901. 



Laboulbenia acanthophora nov. sp. 



Pale smoky brown. Perithecium relatively very large and elongate, 

 the lower wall-cells forming a well-developed stalk, slightly narrower 

 and paler than the main body, which is very long, straight, but 

 slightly inflated, tapering slightly at the relatively short, stout, more 

 deeply suffused tip ; one of the lip-cells forming a median, terminal, 

 erect, slightly curved and tapering, blunt-tipped, dark brown projection, 

 the lower half broader, the whole more than twice as long as a similar 

 second outgroivth which, arising near its base, curves outward on the 

 right side (the perithecium being considered antei-ior). Basal cell of 

 receptacle subhyaline, more than twice as long as broad, the subbasal 

 subisodiametric, darker brown than the other cells; cells III and VI 

 subequal, lying perpendicularly side by side, both several times longer 

 than broad ; cell IV about as long as cell III ; cell V small, obliquely 

 separated. Insertion-cell black, well defined. Outer appendage (broken) 

 simple (?) its basal cells blackened ; the branches curved outward, 

 externally blackened below, and giving rise above to several successive 

 branchlets. Spores 75 X 4.5 ^u. Perithecium (main body) 220 X 50 /ii ; 

 stalk 60 X 30 ^ ; terminal appendage 60 \>.. Receptacle 220 X 65 /x. 

 Appendages (broken) 150 /x. Total length to tip of perithecium 580 ;x.

Laboulbenia Bledii nov. sp. 



Color uniformly pale dirty yellowish. Perithecium more than two 

 thirds free, rather slender, tapering to the tip, which is more or less 

 well distinguished ; the lip-cells rather coarse and prominent, with a 

 sul)terminal blackish shade on the inner side. Appendages divergent 

 and free through the enlargement of cell V: the outer appendage simple, 

 short, four- tn five-celled ; the basal cell of the: inner a[ipen(laLre some-
