PoLYPoiiiJS FuoNDosus.— A Specimen found at West Chester, 
Pa., Oct. 22d, l<S(Sd, was 14 x 1‘J in., and 9 in. hi.ijli, the imbricate- 
cycspitose pilei all arising? from a common central siibtiiherculiform 
stem, o in. thick and about :> in. hi,i?h, much branched above, and 
each branch bearing a liabellifoi'm pileus, 4 in. wide. The surface 
of the pilei was of a slightly sooty tint, indistinctly radiate-stri¬ 
ate, surfa(;e innate-tomeiitose, margin revolute in drying. Pilei all 
dimidiate, llabelliforin, or spatulate, often laterally conlluent, sub¬ 
stance carnose-tibrose, yellowish, moderately tough, so as to bend short 
without breaking. Substance of the stems also hbrose-carnose and yel¬ 
lowish. The plant can not be called brittle (fragilis), nor was there any 
greenish tinge about it. Odor (piite strong, but not disagreeable. Pores 
nearly milk white when fresh, about ^ mi Him. diam., angular and sin¬ 
uous^ margins sublacerate, strongly decurrent on the stems. Spores 
white, ovate d—7 x 4 y. A specimen found at Newlield, at the root 
of a maple, had the pilei mostly entire, but did not differ otherwise. 
PoLYPoKUs FLAvo-viRKNS, 11. &. Ilav. — Tills species has also been 
found quite abundantly at West Chester this season (Aug. to Sept.), 
and has also been observed at Newfiekl. N. J., for several years in 
succession. It is a terrestrial species, and occurs in dry woods. A 
careful examination of many specimens enables us to make some al¬ 
terations in the description given in Grevillea 1, p. Its. The pores are 
at first invariably mill: white, but at maturity they become, like the 
pileus, dirty yellow; they are also quite constantly distinctly sin- 
wnis, but this character is not so obvious in the mature specimens. 
The margin of the young pores is finely subfimbriate and at length lacer¬ 
ate. The pores themselves are ipiite short (2 — 8 mm.), and often dis¬ 
tinctly funnel shaped at maturity. Whole plant firm, pileus excentricor 
lateral, 4—7 inches across, nearly smooth or coarsely lacerate-squamose, 
center depressed, margin undulate and sublobate, and the whole plant 
greenish yellow. Spores white, nearly globose with a single large nucleus, 
4—d // diameter, basidia clavate, 2d x d The pileus is often distinctly 
marked with zones of a darker color. As far as can be judged from the 
description* in 2Gth Hep. N. Y. State Mus., must be very near this, but 
that is said to have the stem smooth and pores minute. P. Jiavo-virens 
has the stem I'oughened by the decurrent pores which can hardly be 
called minute. 
PoLYPouus DKrKNDKNs, B. A ('., Giev. 1, p. 87.—This species has 
been found atXewheld, once under a decaying oak log, and again growing 
from the upper surface of the hollow in a rotten jiine or cedar log. It is a
