Hab. On hardened Agarics, in autumn, rare. Woods near Edinburgh.
Near Tarbet, on the banks of Loch Lomond.
Perithecia often scattered over a whole fungus, minute, erect, conico-subulate,
reddish or brownish a t the base, yellowish upwards, subpellucid,
smooth, furnished with a pore at the apex, by which the sporidia are at
length gradually exuded, and assume the form of a little ball, which
becomes hardened, and exists in that state for a great length of time.
The perithecium is partly hollow, and contains the sporidia previous to
maturity, mixed with a gelatinous pulp, and a few filaments, which,
being evacuated along with the sporidia, were very obvious in several
specimens I dissected ; for, on exposure to moisture, the little ball dissolves
very readily, and is an interesting object under a high magnifier,
The sporidia are very minute.
