Rhachomyces longissimus Thaxter. 
pceimens 
two millimeters, have been obtained in the British Museum on Colpodes evanescens Bates No. 694, Toto- 
nieapan, < luaternala; on < pmtcinus Bates, No. G99, Vera Paz, Guatemala; on C. reflexus Chaud., No. 
]n !_' from Columbia. It shows a certain amount of variation in color, few specimens being as dark as 
the line repr ented in my Monograph. The appendages also are often more widely separated from one 
another, and the axis relatively stouter. It recalls R. Dolicaontis which, however, lacks the successive 
pairs of divergent appendages which are so characteristic in this species as well as in R. tenuis, to which it 
appears to be most nearly allied.

Perithecium relatively small, the lower half or more hidden by the appendages, hardly inflated, 
faintly tinged with brown, tapering very slightly to the tip, which is suffused with dark brown, broad, 
hardly differentiated and slightly asymmetrical. Receptacle very long and slender, the cells of the main 
axis thirty to forty in number, dark reddish brown or nearly opaque, subhyaline below the somewhat 
oblique Bepta, except the lower members of the series, which are as a rule wholly opaque; the cells in- 
creasing slightly in size from the base upward. Appendages straight, narrower distally, rather short and 
appre.ssed, not very numerous; those about the base of the perithecium, about twelve in number, some- 
what larger and longer than the rest, surrounding and concealing it more or less completely; some of the 
lower appendages also longer and curved conspicuously outward, as are the antheridia. Perithecia about 
1 10 X 30 jx. Longer appendages about 140-160 j«. Greatest width of receptacle about 20 ;i. Total

This elegantly formed species is distinguished from R. longmimus, which appears to be its nearest 
ally, by its more slender form, its more slender and differently shaped perithecium and the character of 
nppen 
members of which, unlike those of R. longissimus, are subulate and not recurved.

Perithecium straight, symmetrical, tapering slightly distally, translucent, brown, the tip opaque 
blackish brown, the apex hyaline and blunt, the whole surrounded and more or less hidden up to the tip 
by tin- appendages. Receptacle rather long and slender, the main axis normally consisting of more than 
twenty cells winch are clearly distinguishable, more or less suffused with blackish brown, less so toward 
the base, more or less hyaline at, and obliquely below, the septa; the appendiculate cells giving rise to a 
dense .senes of ,,m,lar black subequal appendages, their inner edges somewhat hyaline, with slightly 
upturned and enlarged bluntly pointed hyaline tips, more numerous distally and forming a dense tuft 
around the peritheeiumwhich they conceal, except for its projecting tip.
