MONOCllAni OF THE LAUOULIIENIACE.H. 3o5 
Tliis genus presents one of tlic uiobl curitjus and clearly dcfincfl tyjx's among the Lalioul- 
bcniaccaj, and altliungh the buccccJini; genus Diploniycos is cvidciilly its nearest all v. its im- 
mediate relations to other genera are very ohscure. Owing to the early inuhiph'cation of 
appendiculatc cells, Um relation of the appendages to tlic points of orimn of the pcrilhecia have 
not been deterniincd. The exact jirocess l)y which the terminal series of cells is formed is also 
not clear. This series docs not have the same appearance from all sides, and it ap]i( ars 
to be produced as a result of the pucccssive separation of the cells which form it, through 
the proliferation of the receptacle to the right and left of a c-onnnon centio witliin which the 
pcrithecia arise. Tlie appendages arc unlike those of any other genus, and result from the 
formation of successive sympodial branches, which are formed in a verlic..! rudial plane. 
When young they bear the antheridia usually near the base, sometimes altcrniiting irre'ni- 
larly with prominent beak-like branchlets of chaiacteristic ajipearance, the two forming a 
single external vertical scries (Plntc X, figs. G and M). The trichogynes arc oflen \ery 
liiglily developed; varying greatly in tlieir luxurijuico In difToront sperimonf? of ll)0 Rnmc 
species. Ill some cns<*s Ihey are not unlike llie ap[>ond;igo« in general nppf\')rnnrr, flie form and

cry distinct and characteristic modification of tlic receptive tips of their nitimnto hrnncli- 
lets (fig. 17). Fig. 1, Phite 11, represents another instnticc of a highly developed female organ. 
The perithecia have but four wall-cells in each row, and appear tO contain but two ascogenic 
cells. Tlic species all occur on beetles belonging to the Staphylinida;, which arc found in very 
wet situations.

Troc. Am. Acad. Arts and Sci. Vol. XXVIII, p. 182. 
Pcrithecia one to three, pale, becoming reddish or purplish brown, straight, basally inflated, 
distally sub-cylindrical ; tapering abruptly to a symmetrical truncate ap(^\, the stalk-cell cylindri- 
cal, often very elongate. Receptacle somewhat flattened, consisting of a small narrow basal cell, 
brown but more or less translucent ; a larger suli-basal cell, which bulges abruptly on one side 
and is almost wholly opaque except along this prominence: while the distal of its three cells is 
hyaline, becoming reddish brown, very variable in length, sometimes much longer thnn thr bnsal 
and sub-basal ccUs together. The larger appendages consist of a single long shnulcr flat reddisli- 
browu basal cell, bearing x<iTy numerous antlieridia or sterile beak-like branchlets in a sinde 
vertical row, the terminal branches larger and themselves one to three times branched, the ulti- 
mate branchlets often oblirpiely septate, the septa dark or terminating in pointed beak-liko 
cells. Spores, 40 x 4 u. Perithecia, 128-140 x 22-26 /^. Stalk (longest), 480 fx. Appendages 
(longest), 185 /t. Receptacle, 110-180//, greatest width about 45 /i. Total length to tip of 
perithccium, 220- 750 /z. 
On Acylophorm pronus Er., Maine and Massachusetts; A. flavicollk Sachs., Pennsylvania 
and Kansas. A.flavipes Lee, Florida. 
The specimens of this singular species, which were found on the abdomen of A.flavipeB from 
Florida, differ from those on the other liosts in their much smaller size, and arc not more than 
half as large as the ordinary form. Yet tliere seems to be no doubt cone^rning their identity.
