In old sandy fields, Sept.-Oct. The initerior of the stem in tle young plant is, like the gills, violet-pur ple, and the club-shaped base is covered with a tomentose coat, to which the sand adher es tena- ciously.

Related to A. laccatus and A. ochtrolpuGrpureus, B. Hymenochaete aggl utinans.-Of r ather loose texture and of a light

yellow color at first, becoming firiner and of a light tan color or rufous tint as the bristles are developed; closely adnate withl a de- terminate margin which is tomentose at first; folmiln orbicular or elongated patches or sometimes entirely surrountding the twig or limb on1 which it grows for an inich in length.

Common in Autumn in swampy thickets onl Andromecta, J7Vaccia- ium,> &c., without much discrimination, fastening the stems or branches together wherever a dead twig or branich lies in contact with a living one; turns black and dries uip during the winter. Helotium naviculasporum.-Stipitate,firm, white, becomingf pale

yellow; disk convex about 1-20' acr oss, stem about thie same length asci rather broad; p4raphyses slightly thickened above; sporidia about .001' long, broad boat-shaped, filled with graniular matter.

Oni old leaves decayinig in stagnant water, July. Exobasidium discoideum.-Fleshy anid firtmn., but of looser texture

witlIin; at first turbinate and concave above, but the margin soon expands so that the fungus takes the shape of a dotuble convex lenis

1 2' across and I -" thick; pale green and smooth beneath, hy- menial suirface soon white pr-uiniose, but assuminig a pale lilac tint in drying. Spores as in E AndcromecZe, Pk., obscui'ely uiniseptate and bent at one end, aboout .0008' lonlr

Attached to the unider sidle of the leaves of Azalea viscosa, July.

Sphaeria pyriospora.-Perithecia nestling in the inner bark, scattered or subcoinfluent, ofteni seriately arranged, rtupturing the epidermis longitudinally, whiite within becominig black; ostiola slightly promineent, miniute; asci cyhindric, turgid; sporidia long pyriform, about .0012' long, crowded in the asci. Spermatia oblong(, miiiute.

On dead blranches of Chionanthucs Virglnica, May. Gymnosporangium biseptatum.-OIi branches of Wlhite Cedar.

Appearinig in April, burstinig thr-otugh the epiderinis in little reddish- clhestniut colored velvet-like patches whlich, about the middle of May, pass into the tremelloid state, swelling ouit into gelatinous masses the size of large peas; not so distinctly foliaceous as in G. Juniperi. Spores long pedicellate, mostly biseptate.

The portion of the br anch occtipied by the ftingns becomes en- larged, swelling out on all sides and increasingo in size from year to year till finally branches no larger thati a pipe stem bear oblong swellings an inch or more in diamieter and four or five inches long,. Sometimes the fungus attacks the trunk of a small tree or some ot the laroer branches. causinso swellings of a much laro-er size.

the village of Pine Plains. The physical features of the township are sufficiently varied to give this section certain botanical advan- tages nlot usually lpossessed by many others. First, there is Stissing Mounitain, -which consists of two adjoining peaks, or graduial eleva- tions, one of tlhem risitng above the plain to the height of nearly a tho)usand feet. On or near its nearly naked summit grow Potentilla tridentata, Ait., 3Betrula papyracea, Ait., Prunus pumila, L., etc. The mounltain, which is about six miles in length, has nio connection with any other ran(re-being not quite equi-distant from the Taghkanic, Catskill and Fishkill ranoes. Our hills, with exception of the moun- tain, are mostly limestone-the plain being a sandy loamn. There ale over a thousand acres of untilled marsh land in town, besides quite a number of lar ge cold swamps; in the marshes flourish Betula pu- mila, L., 1Blephilia hirsuta, Benth., Andromeda polifolia, L., Myrica Gale, L., Alenyanthes trifoliata, L., and a number of other plants un- usual for this latitude. All this, with five or six good sized ponds and three large creeks flowing through the township-making a sec- tioni diversified with mouniitain, plain, hills, valleys, ponds, creeks, swamnps, and marsnes-caninot fail to offer a most inviting field to the active botanist.

I take, I trust, only a pardonable pride in the goodly number of Ferns, Solidagos andl Potamogetons-my favorite order and two favorite genera-which grow here within two and a half miles of the village. Of Solidaaos I have alr eady detected, within the above small circuit, twenty different species, and thirty-three species of Felns, besides thlree or four varieties of the latter. In a futulre arti- cle, I shall give their names in full.
