Puoro-Microcrapuy. — Dr. Charles Jewett, of Brooklyn, N. Y., 
has produced extremely perfect photographs of Amphipleura pellucida 
with Tolles’s one-fifth immersion objective, B ocular, and Zentmayer’s 
amplifier. 
A New Funeus. — Mr. J. P. Moore has presented to the San Fran- 
cisco Microscopical Society a specimen and description of a remarkable fun- 
gus found growing from a beam in an abandoned drift, four hundred feet 
below the surface, in the Yellow Jacket Mine, Gold Hill, Nevada. The 
growth commences as a pure white mycelium bursting out of the wood. 
The specimen described was three feet four inches long, of a light buff 
color, and consisted mainly of a three-parted stem, two or three ‘inches 
in diameter, attached by means of a disk eight or ten inches wide. To- 
wards the other end the stem divided into short branches greatly resem- 
bling in shape and arrangement the young antlers of a stag, the three 
terminal ones being much the most vigorous and conspicuous, forming a 
Perfect trident. The gills are distant, decurrent, notched, and sinuate, 
and of a pale straw color ; the spores ovate or round, exceedingly minute, 
and borne on true basidia. The plant is called by the miners the lily 
of the mines ; by Mr. Moore, Agaricus tridens.
