straight or slightly curved, rather slender, of about the same diameter throughout, the tip usually abruptly 
distinguished, and more or less conspicuously bent to one side, tapering Dttl little t<> (lie rather I. mad 
blunt undifferentiated apex. Receptacle rather narrow, the basal cell dark red-brown below, nearly 
hyaline above; the central cell of the lower tier dark red or red-brown, lighter or hyaline at the base; 
the cells on either side symmetrical, blackish brown, opaque, extending upward so as to partly endow 
the base of the second tier, the margins of the two tiers coincident: the second tier composed of from 
seven to nine cells, hyaline or becoming suffused below with reddish brown, bearing a well defined Lirply 
pointed purplish slightly asymmetrical antheridium, on either side, which is subtended by fr one to 
two typical rather short appendages: the upper tier very similar to the middle, or slightly larger, nearlj 
hyaline, the single perithecium rising to the right of the median appendage, the right half of th. tier thus 
somewhat larger and higher than the left, three typical appendages usually present on either ikfe. IVri-

This small species is well distinguished by its geniculate habit, and the abruptly bent tip of its elongate 
single perithecium.

Form short and stout. Basal cell geniculate, more or less suffused: the lower tier more or 1. J, 
sometimes wholly, suffused with reddish brown; the margins darker, more or V s translucent. Without 
contrasts, the outline somewhat uneven, the transition to the middle tier indicated by a disiinet promi- 
nence: the middle tier consisting of from nine to (rarely) thirteen calls, hyaline or subhyahne with slight 
lateral suffusions; the marginal cells ending in a slight hyaline rounded project.on, not extendmg higher 
than the venters of the somewhat suffused curved antheridia or extending upward nearly to «h- middle ..f

A species not very frequently met with and first observed by Mr. Bullanl. ™--*"dA tier 
it is clearly distinguished from other species having a single perithecium by its asymmetrical n Id t 
long appendages, and red-brown translucent suffusions, which often extend to die ^j*^ f 
middle tier without involving the septa. The species is further exceptional, like D. '-"'' .^ 
numerous appendages developed on the cells of the middle tier. Curiously enough it is ^
