is easily distinguished by its slender form and translucent receptacle, the basal cell of which is very small 
and conspicuously suffused. The material was however too immature for description.

Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 432. April, 1900. 
Perithecia commonly two, long and slender, a basal middle and distal portion distinguished, corre- 
sponding to the basal, middle and the distal wall- and lip-cells, the basal portion slightly inflated, purplish, 
the middle distinguished from it by a slight elevation at the septa; the middle nearly hyaline, rather 
abruptly narrowed, its margin slightly concave owing to a slight distal enlargement, which, in mature 
specimens, distinguishes it rather abruptly from the much shorter narrower subcorneal mostly symmet- 
rically truncate colorless distal portion; the stalk-cell rather short, concealed by the appendages; the 
basal cells forming a squarish base. Receptacle relatively small, symmetrical or asymmetrical, the basal 
cell translucent brownish, the subbasal cell very small, flattish, wholly involved by the deep nearly opaque 
suffusion of the lower half or more of the upper cell, which is nearly hyaline above. Appendages short, 
slightly exceeding the base of the perithecium, rather rigid, slightly divergent, for the most part dark 
brown; forming a rather dense tuft, many ending in pointed cells, the slender terminations straight or 
bent and forming the beak-like cells characteristic of the genus. Spores 36 X 4 //. Perithecia 
a, the stalk-cell about 35 [i. Receptacle about 85 X 35 j«. Appendages (longest) about

On Phihnthtu sp. indet., British Museum, No. 365, Hungary. 
A species well distinguished by the successive ridges on the perithecium and short dense appendages. 
It appears to be rare as I have met with it only once among the many hundreds of Philonthi examined. 
It is possible that the generic determination of the host may not be correct. 
Teratomyces Zealandica Thaxter. Plate XLIX, figs. 1-3. 
Receptacle with a distinct distal obliquity, opaque with the exception of a hyaline area just above 
the fi><>t, the margins straight, the distal portion relatively narrow, the base relatively broad, the suffusion 
involving the bases of the appendiculate cells which are relatively numerous and narrow and more or less 
suffused with brownish yellow. Appendages sometimes scanty, but slightly divergent, concolorous through- 
out, nearly hyaline or pale yellowish; the basal cells of the larger branches relatively slender, the external 
branchlets and numerous beak-like cells hardly more deeply colored. Perithecia relatively large, long, 
rather slender, slightly inflated throughout, the blunt tip more or less abruptly distinguished; the stalk- 
coll very short or almost obsolete, hidden by the appendages; the basal cells relatively small and not 
distinguished from the body of the perithecium. Spores about 50 X 2.5-3 pu Perithecia 150-180 X20- 
28 /«, basal and stalk-cells together about 35 ji. Longest appendage 180 ft. Receptacle 75-125 X 15- 
18 (has.) 22-30 ft (distally).

This species is well distinguished by its nearly isodiametric receptacle, as well as by its appendages, 
which are either wholly hyaline, or evenly and only slightly suffused; while the dark ring which sepa- 
rates the stalk-cell of the perithecium from the receptacle (fig. 1) is at least not visible in other species. 
Teratomyces petiolatus Thaxter. Plate XLIX, fig. 7.

Receptacle nearly symmetrical, almost wholly black, slender below, expanding rather abruptly dis- 
tally; the appendiculate cells relatively large and long, translucent, brownish yellow, subtended by a 
slight enlargement. Appen, lages numerous, spreading, the larger ones consisting of a very large colorless
