(PROFESSOR PECK's accouilit of thec AMANITAS, Cointin1ued.)

"In other species the volN-a is not distinictly niembrallotus, btit is more floccose or scalv and friable in its chiaracter. It envelopes the youtng plant, btit the distinctioni between the piletis and builbouis base of the stem is sooln manifest, and as tile stern elonigates the uipper part of the volva is separated froim t'.e lower part, and persistenltly adlheres to the stirface of the pilelus.

J"IG. 135. HYD'-NUM ZO-NA'-IFum. A spccies with a tough almost leathery tex tuire, havinig a surface of beautiful brown silky lustre, somewhiat zoned and with radiat ing strie. The s?ore-hearing spines are sho(wn in thle upper figuires; two of them shlow

coal-scu d caps5 thoughi the sttms arc separate. The photo was miade from specimens col lectecd by the r-oadside in the woods of the State Farm, located in the sandstone hills c-f Fairfield Co., Ohio, Aug., 1905.

As this expands its covering or calyptra breaks up into superficial scales or

warts. These are often angular or pyramidal in form, and sometimes unlike the piletis in color, anid afford a beautiful orniamentation. The

part that remains at the base of the stem often breaks up into mealy or

floccose scales, and sometimes wholly disappears wheni the plant matures.

Genierally a smooth pilenis indicates a perfect renebralnous volva, and a

warty one an imperfect floccose or evenescent one. Sometimes, especially after heavy rains, specimelns, whicli normally have the pileus warty, are

fotulnd with a smoothl pileus; but these are onily occasional, and probably

mostly accidental cases, the warts having been waslhed off by the raim. "Most of the species are solitary or gregarious anid of moderate or

large size. The piletis, when fully expanded, is nearly plane and quiite reg

ular, so that these Agarics are among the most noble and attractive in their

appearance. Mlany of them have a thin pellicle or ctiticle, which, in thc

olinig or moist plant, is slightly viscid. "Tlhe lamellae in nearly all the species are white or whitish, and free

from the stem. Usuallv they are narrow toward the stem, and cease julst before reaching it. thuis leavinlg a small free space arouind its apex. In maniy species the slhort ones that intervene between the long ones are ab

ruptly terminiated at their innier extremitv, as if trtlcated or clut squiare off.

"The stern is uisutally long and wvell formed, and in most species is more or less thickenled or bulbouis at the base. In some species it is hol low or stuiffed with cottonly fibrils; in others it is solid. In the greater numriber of species it is fuirnishied with a membranouts ring or annulus, that suri-rounds it rnear the top like a flabby collar. In the young plant this is

stretched from the stem to the margin of the piletis, and wholly conceals

the lamellae. A.s the pileus expands the anntulus breaks loose from its

attanchment to the mar-ginl, anid remains adhering to the stem. In some

species this rupture is not always clean and even, small portions remaining attached to the margin. The anntlts then has a lacerated or torn ap

pearance."

PORT]RAITS OF AMANITA.-Iti the BULLETIN we have given heretofore

the following species:-Amanita strobiliformis (from Atkinson) p. 56; an(l A. rubescens. Here we give Amanita verna and A. solitaria. Pro

fessor Atkinson figtures, in Mushrooms Edible and Poisonous, Amanita

mlsscaria, A. phalloides, A. verna, A. floccocephala, A. velutipes, A.

cothulrnata, A. spreta, A. caesarea (colored), A. rubscens (colored)

Mcilvaine gives in his book on mushlrootms One Thousand American

Fuingi, colored plates of Amanita spreta, A. phalloides, A. muscaria, A. frostiana, A. chlorc,sonma, A. rubescens, A. strobiliformis, and a half-tone

of A. mtuscaria. In Ninia L. Marshal's Muishroom Book there are given

half-tones of Anmanita phalloides and A. muscaria. Professor Peck's Re

ports contain colored plates of somne species, as Amanita caesarea, A.

rnibscens, A. pllalloides. A. verna, A. muscaria.

TIME FOR THE BO-LE'-TI.-At ani earlv opportune time we must say

sometliing in extenso for the niumerous species of BOLETUS. This is the

season to stuidy them in the field. Photograplhs are desired,-but the

specimens should be identified by suich authortities as Peck, Morgall, Atkini

soni or Beardslee.

FIG. 136. CAN-THA-REJC-LUS AU-RAN-TI '-A-CUS. Orange Cantharelle. Edible. A common and easily recognizcd bright orange-colored species that occurs from summer to late autumn. It grows on the grounid or on very rotten wood. The yellow decur rent gills are forked, and thepileus is iunniel-sliaped, at least depressed. The margin is strongly inrolled when young. The color may vary from deep orange to ochre-yellow, often brownish at the centre. Plaints from which the illustration is made were col Icleed in open, moist, shady, rich woods near Columbus, Ohio, Aug., 1905.

FIG. 137. 1.O-LE'-lU -u'- is. ELi1BIE BO01Erus. This is one of the vcry large species of Boleti, growing in opeii wvoods along their borders, a:id in open places. It is abundant in warm.. wct weather of sumimer aiid early autumnii. The color of the cap

may be dull reddish, reddlish-browni, tawvny-brown or yellowish. The tubes are white at first, then become greenish-yellow, or ye'llow wvhen mature. The flesh is white or tinged

withi yellow. The short stem may or may not be enlarged ait the base. The ha:t-t,one was3 made from a 'photoDgraph of a specimen collected on the State I'drm, margin of woods, Fairfield Co., Ohio, August, 1905.
