nelanocephalus Grav., Europe and on 0. fulvipennis Fabr. in th

0. myrmeropkiku Kirs, from Tilgate, England, in the British Museum, No. 440, and in the Berlin Mu- 
seum, No. N12, on 0. melanoccphalus Grav., from England. This form, however, does not seem separable 
fn tm the type which is clearly defined and appears to be confined to Europe. 
Rhachomyces Cryptobianus Thaxter. Plate XLV, fig. 15. 
Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 437. April, 1900. 
Peritheeium hyaline or pale straw-colored, very long and slender, nearly isodiametric throughout, 
almost straight, the tip apparently blunt and not well differentiated. The main axis of the receptacle 
consists of about sixteen cells; the basal cell and those immediately above it slender black and opaque; 
the rest becoming larger upward, hyaline suffused or mottled with reddish brown. Appendages numer- 
ous, slightly divergent, becoming longer from the base upward, nearly opaque except along the inner 
margin and at the tip which is generally bent abruptly outward, a group of about six below the base of 
i he peritheeium much longer than the rest and curved outward in a tuft, those arising about the base of 
the peritheeium very elongate, erect, with straight blunt tips, reaching nearly to the apex of the peritheeium. 
Peritheeium 490-450 X (about) 35 p. Receptacle 275-430 p. Total length to tip of peritheeium 650- 
800 /«. Longest appendages 300-430 fi. 
On Cryptob'uim capitatum, Paris Museum, No. 172. Brazil. 
A fine species remarkable for its long slender peritheeium and the characteristic dispositon of its 
B | >\ M-ndages near the base of the latter. 
Rhachomyces Oedichiri Thaxter. Plate XLV, figs. 8-9. 
Proc. Am. Acad. Arts and Sci., Vol. XXXVII, p. 38. June, 1901. 
Receptacle strongly curved, rather short, the lower cells especially more or less suffused with clear 
brown, the basal cell slender, the cells of the main axis above it successively larger, about ten to twelve 
in all. Appendage hardly ever reaching to the tip of the peritheeium; the shorter margin alone subulate 
and straight, the rest appressed, denser toward the base of the peritheeium, where they form a tuft which 
does not wholly surround it, curved slightly outward, somewhat attenuated; tips abruptly recurved or 
subhelieoid. Peritheeium somewhat inflated with a more or less evident submedian ridge, hyaline, with 
the exception of several longitudinal dark brown marks at the tip, the base concealed by the appendages. 
Spores 36 X4p. Perithecia 90-110 X 30-35 ft Total length to tip of peritheeium 220-250 //. Long- 
est appendages about 90 //.

• ITua i pretty species is distinguished by its short stout curved form; absolutely hyaline peritheeium, 
« .th small subtenant! brown patches; and characteristic appendages, which are mostly similar, gradually 
longer from below upward and abruptly recurved at the tips, forming a little hook. The species is very 
'-..slant in its eharacters, and appears to be most nearly related to B. Phikntihinus. The host is astaphy- 
Innd supposed to be a new species, and is allied to Pinophilu,.
