THAXTER. — MONOGRAPH OF THE LABOTJLBENIACELfi, 311 
New Pomerania. Berlin Museum, No. 1281 and 1298. On the bead and at the base of the pos- 
terior legs. 
This species is chiefly peculiar for its long flat appressed appendage, the axis of whi< h consists of 
eight or more cells including the basal cell. The spine arises from the base of the eighth o II where its 
position has been determined. The neck of the perithecium is relatively stout and I i "bloated" lool 
and is usually not abruptly distinguished from the venter.

Perithecium amber-brown, the venter slightly inflated, the neck not abruptly distinguished, tapering 
slightly; the tip usually abruptly narrower, the posterior tip-cells forming in inconspicuous irregular 
truncate or rounded bilobed projection somewhat more prominent than a similar projection formed by 
the anterior lip-cells; basal cells relatively very large, forming a short, well-defined stalk, hyaline or col- 
ored above, often carrying the base of the perithecium beyond the tip of the apjMwlage, and consisting 
of an inner cell next the appendage and two superposed outer ones, the lower of which (secondary stalk- 
cell) is smaller; the stalk-cell below these wholly united to the stalk-cell of the appendage, rather stout 
and short, separated from the cells above it by a horizontal septum, which may be slightly oblique or (as 
in the California variety) strongly oblique, in which case the secondary stalk-o II extends downward 
beside the stalk-cell so that only the lower third or quarter of the latter a free externally. Stalk-cell of 
the appendage relatively large, as long as or often longer than that of the perithecium and about half a 
broad, usually bulging externally, its outer margin usually cur\< d symmetrically from its base to the bast 
of the basal cell; the latter relatively small, deep amber-brown, half as long as broad, pointed distally 
between the antheridium which arises from its inner side and the base of the first fertile cell above it 
which, with the other fertile cells, are large and prominent, thick walled, much flattened, and obliquel] 
superposed, distinguished by rather deep constrictions, seven to ten in all, or rarely more (seven to four- 
teen in the Californian form), the original number being increased by the terminal proliferation of the 
appendage; the antheridia borne on the inner side of the appendage, their very long but not abruptly 
differentiated necks extending obliquely upward, appressed in a double series; the upper antheridia 
often infertile, becoming septate and irregularly swollen. Receptacle relatively short, the t wo cells nearly 
equal. Spores 28 X 3 ft. Perithecium: venter 50-90 X 40-54 ft; neck 90-125 X 15 IS tr, stalk (ha. sal 
cells only) 72-100 X 25-35 ft. Appendage 60-100 ft, stalk-cell 30-45 ft. Receptacle 70-75 X 22 //. 
Total length to tip of perithecium 250-360 ft. Specimens on legs often much smaller. 
On L'nnosina jont'nialis Fallen. Kittery Point, Maine; vicinity of Cambridge. Ma .; OB TAmot M 
sp., Berkeley, California. Usually in a dense tuft on the side or near the tip (inferior) of the abdomen 
and near the base of the posterior pair of legs. 
The Californian material, figs. 3-4, from two specimens of the host, differs con antly from the 
abundant New England material as noted in the description, as well as from the Pact that the venter of 
the perithecium is longer and less distinctly inflated, while its apex shows no perceptible modification of 
the lip-cells. The species is remarkable for the repeated proliferation of its appendage, wind, mak- 
the primarily terminal spinose cell intercalary, the distal cells unlike those of any other species, with the 
exception of the nearly allied 8. Papuanus, being usually sterile. The host is a small fly, t with 
coarse hairs, and captured by sweeping around muddy ponds or over wet places m woods.

Venter of the perithecium dark amber-brown, relatively small and rather prominently inflated, oval 
to elliptical; usually not abruptly distinguished distally from the hyaline or yellowish neck, winch in 
well-developed specimens is very elongate, tapering very gradually, in others shorter and stouter, the 
tip clearly distinguished (abruptly so in the shorter forms), subcorneal, the posterior hp- Is forming 
a narrow, subtruncate, slightly recurved apical projection beyond the two laterally placed, papilla!.
