Longer and more slender than the type; cell V not greatly broadened, so tliat the |>erit!ieeiuin and 
appendage diverge but slightly. The outer appendage nearly end, brown, relatively von long, ta|H*rini' 
one or sometimes more than one of the three lower cells producing externally or laterally well-dcvelojied 
branches of the characteristic type, which are long, slender and more or 1< pendulous. The inner 
ippendage recurved, more or less pendulous, relatively slender and similar to ;i well-developed branch 
which arises on its inner side from the third cell above its base. Perithecium nearly erect, the tip well 
distinguished, bent slightly inward; the lips somewhat spreading. On Brarhinu* (j< icvlaJhu I »« j .

A very large and striking form, to which the pendent branches of its appendage - give a gne ful habit 
Unlike the var. incurvata, which occurs with it, the two basal < ell do not form a st; k clearly distinguished 
from the distal portion of the receptacle, and although cells IV and V are greatly enlai d, they arc 10 
arranged as to bear the appendages in the usual vertical position. 
Var. Oaxacana nov. var. Plate LXIII, fig. 7. 
Perithecium suffused with rather dark brown, tapering and curved slightly inward from about th< 
middle to the tip, which is abruptly distinguished, subcapitate, the li] translucent only about the pore. 
Receptacle somewhat bent, the subbasal cell broader and Several times longer than the basal • II; both 
evenly suffused with pale dirty brownish and contrasting in color with the darker brown distal portion 
which is concolorous with the perithecium, except cell V, which is somewhat paler, indistinctly marls I 
by transverse stria*, and prolonged upward and outward beside cell IV, earning the in rt ion-cell out 
free from the perithecium almost horizontally. Outer appendage long tapering and slender, the lower 
half suffused with dirty brown, the distal hyaline; the successive cells bearing distally and externally

consisting of a basal cell which gives rise laterally to a single small antheridium on a \rr\ hort rtalk-ceU, 
and a hyaline terminal branch of five or six cells each bearing an upcurved branch; the branches producing 
upcurved branchlets, the lowest of which is distinguished by a blackened septum.

The single type of this variety which has been examined, approaches var. / xitda in the form of it 
perithecium, but differs both in the form of its appendages and in their relation to the receptacle, through 
the modification of cells IV and V.

nearly straight, divergent, hardly incurved, becoming more or k brownish, relatively somewhat longer 
and more tapering than in the type, the subbasal cell producing from its left side I short wdMeveloped 
five- to six-celled branch, recurved, and bearing branchlets of the characteristic type from its con* nde; 
the second cell producing on its concave side a two-celled branchlet, the lower cell oi which bears one 
and the distal two of the characteristic branchlets. The inner appendage closely r, emblmg that ,.t t ,

Perithecium as in the type, but the tip quite different, narrow, bent abruptly inward at nght angl. , th.

While the appendages of this variety are not unlike those of the var. pendula, « diffe. n the form 
of the perithecium, with its abruptly inbent tip. and in the differentiation of the receptacle mto a stalk-part
