Receptacle consisting of two cells, the upper bearing one or more |>trit! cia laterally, and an aiithcri- 
dial appendage terminally. The appendage consisting of several superposed cells, die lowest normal! 
sterile, those above it bearing opposite lateral branches distally, the series ending in :i terminal sterik 
branch. Antheridia simple flask-shaped, free, borne in small groups on short branchlets. 
The two species included under this name are so unlike, that the inclusion of 8. Stilicolru must l>. 
regarded as only provisional. It is therefore somewhat difficult to define the limits of tlic genus with 
great exactness. In S. Conosomce the perithecia tire often several in number, budding from the subbasal 
cell of the receptacle or from the usually sterile cell above it, which normally forms the base of the append- 
age. The main axis thus becomes a scries of superposed cells which, except the basal ones, parate by 
an oblique septum distally, on one or both sides, perithecia, in the case of the two lower cells, and antheri- 
dia] branches in the others; the series ending in a long terminal "appendage." An examination of more 
species is needed to indicate the limitations of the genus and its immediate relationships. Among the 
other genera it approaches Rhizomyces in the character of its appendage, but the resem bl ance is other- 
wise slight.

triangular in outline; the subbasal cell about as broad as long, and similar to the cells of the appendage,

sides of the cell, like the antheridia! branchlets. Appendage consisting of five superp. I Mibequal i ■ lis 
slightly longer than broad, the basal one sterile, or not infrequently producing one or two perithecia as in 
the subbasal cell below it: the three cells above slightly larger, the upper angles ..para ted by obliqu 
septa to form small cells on either side, which bear short one- or few-celled antherid.al branchlets; the 
terminal cell somewhat smaller, bearing a simple terminal several-celled branch in addition to the lateral 
branchlets, all of which usually appear to be sterile. Antheridia with broad necks grouped m twos or 
threes. Perithecium darker brown, more or less symmetrically inflated; the tip hardly modified; the 
basal cells collectively broader and nearly as long as the stalk-cell. Spores 35 X 2.5 /i. Perithecia 5

This species is not uncommon on its active host, sometimes in company with Smert^myces, t>* 
is usually found in rather poor condition; the terminal portion becoming easily broke, or injured so 
that an abnormal production of branchlets takes place. It occurs on all parts of the host, butesp, „ a lly 
on the elytra.
