The Agaricaceae constitute a rather large family of the Basidiomycetae and are commonly known as the "gill fungi." The family is characterized by having the spores borne on club- shaped hasidia arranged in a definite layer known as the hymcniiiin, which covers a number of radiating plates, the lamellae or "gills", suspended from the lower surface of the pileus, or cap. A stipe, or stem, is usually present, but may be wanting. Many of the species are edible, and some are considered a great delicacy. Others are poisonous, and may cause serious illness or even death. A few are parasitic upon certain higher plants, notably i;pon the roots or trunks of trees, when they may cause extensive injury to the timber. ]Many are beautiiully colored, red, yellow, purple, brown, white, etc., or quite large, or otherwise striking in appearance. For these reasons and others these plants are interesting objects of study. The present paper is essentially a preliminary report < m the Agaricaceae of Ohio and consists of keys to the genera and species reported as occurring within the state. A glossary of descriptive terms and a bibliography of the literature pertaining to the Ohio species and other works, which will lie found help- ful to the student, are included. The list of species has been made up from the works (see bibliography) of Lea, Morgan, Hard, Lloyd, Peck, Berkeley. Kellerman and Montague. Besides the species thus published, the list has been augmented by reference to specimens in the herbarium of the New York Botanical Garden, the herbarium of the state botanist of New York, the herbarium of the Ohio State University and by the collections of the writer. Thomas G. Lea collected in southwestern Ohio, 1(^34-1844, and sent his specimens to Rev. ]\I. J. Berkeley, in England, who described a number of new species from them. Others were referred to existing species. ^Morgan, a number of years later 4(i-J The .hjaricaceac of Ohio. 4G3 ( iSjS-Kp/), collccU'il in tlic same rci^inn. lie ^really exleiuled Lea's list (althouf^li lu' iliil iK't red j^Miizi' all the speeies ])re- \ii)iisiy reported by 1 .ea ) and de>cril)cd a mimlici- nf new species. W . S. Sullivant, an eminent lir\()logist of ('Dlumbus, sent a num- ber i>f collections to Mnntaf^iu in Paris diirinj^f the early fifties, some of them witli iha\\ing;s hy Mr. Sullivant or hy Mr. Robin- son who worked with him. .\hintaj^ne described fifty-five new species from these specimens. It seems remarkable that none of these species have been certainly recognized since. Most of them are probably to be referred to other species, or at least are in'w ixcognized by other names. I'eck has described species based on specimens sent to him bv Ohio collectors, Morgan. I.loxd. Kellerman and others. Some of Peck's .\'ew ^'ork species have rdso been liinnd m • )hiii. Tlis types arc all. oi- nearly all. pre-erved in the state luTliariuni at .\lbany. Ilai-(1 collected in several ]:)arts of the state and pub- lished his results in a well illustrated book. Professor .Atkin- son, of Cornell T University, also described several species from material >ent t(j him l)y Kellerman and Hard. The list at present includes approximately five hundred and forty (540) species, .^ome of these are of doubtful dvterniina- tion. In many cases the collections were not preserved, and it is impossible at this rlatc to confirm or correct the determination. The type specimens of Montague liave not been available to the writer for study, and, except for a few species of Marasmius, Morgan's types were not preserved. \\'heLher these will all |)rove to be valid species must be left for future study to deter- mine. Moreover, the list is not claimed to l)e complete. There are doubtless many species occiu-ring in the state wliicli have not yet been reported, for some sections have scarcelv been woiked over at all. Before it is possible to have a fairly complete and reasonably accurate state list, there must be a large number of specimens from dififerent parts of the state assembled in acce.s- sible herbaria, preferably, the state herbarium. If notes on the fresh plants accompany each specimen, the collection will have much greater value. 46 1 ProccciliiKjs of Ihc Ohio Stale Academy of Science. Ill ])reparing tlie keys, llic most a])i)arent characters possible liave been employed. The aim lias 1 een to produce accurate and usable keys, rather than to exhibit relationships of species. Some of the keys have been tested by use by mycology students at Miami University for several years ami at the Ohio State Uni- versity during the present year. Most of them have been re- vised several times as suggested 1)\- use. The work is based largely on j^ulilislicd descriiitinn^. and in some cases altogetlier. These are sometimes so l)rief or so lacking in precise detail that it has been difficult to find reliable and well-marked characters upon which to sci^aratc species. This is especially true of species founded wholly ujion ilried specimens. Xotwithstanding such errors, misconceptions and incorrect conclusions as doubtless occur, it is believed that the pa]ier will prove helpful to students, amateur mycologists and otliers in the determination of ( )]iio Agarics. It is offered as a summary of our present knowledge of tlie Ohio plants, and is to l)e re- garded as only a preliminary study. It is not within the scope of this paper to discuss the species in detail, so that many points of interest and of some impor- tance must necessarily lie omitted. With each species included, however, a list of references to the most available and useful works is given. One or more of these should always be con- sulted before reaching a decision as to the determination of any ])lant. Idle matter of the classification and nomenclature of the Agaricaceae is still in an unsettled condition. It has seemed best in most instances to follow the arrangement given by Saccardo in his Sylloge Fungorum for two reasons: It is not the pur- pose to present a critical study of the nomenclature of the family, and most of the available works on this group will lie fouml to follow a similar system. The writer wishes here to acknowledge his many obligation? to Dr Tlrucc Fink under whose direction the work was under- taken. He is also indebted to Dr. A\\ A. Murrill for the privilege of examining sj^ecimens in the herbarium of the New York The Agarkaceac of Ohio. AC^ I'.dlanical riardi-ii ; lo C II. I Vn-k for the dclennination rmont.

C. pilularia, C. xantbopila, C. pbyscopodia and C. tagetes were described from specimens sent to Montague by .'^ullivant and bave not been recognized since. -Morgan's description of C. estensis is rather meager. It is probably a form of C. dryophila or perhaps is identical with C. strictipes. The plants referred by Hard (p. 108) to C. ingrata Sebum, should probably be considered a form of C. confluens. According to Berkeley (Outlines of British Fungology. p. 117), the principal difference between the two species is that in the former the lamellae more nearly approach the stipe. Some writers believe that C. tenuipes and C. amabilipes are identical. Sclnveinitz described the former as having a stipe 15-30 cm. long, pileus depressed and subumbonate, plants grow- ing among decaying leaves. The C)bio ])lants grow on deca\ed wood, the pileus is convex-expanded, and the stipe is varial)lc in length, but seldom more than S-io cm. long. Peck's description of C. amabilipes fits our plants more closely, and unless we as- sume that Schweinitz had very exceptional specimens, they should l)e known by Peck's name. IJoyd says the pileus is slightly viscid, but we have never found it so. (^lyc. Notes I : 199) 508 Proceedings of the Ohio State Academy of Science. MYCENA FR.

P. sapidus, which has pale lilac spores, is usually regarded as a Pleurotus because of its obvious relations with some species of that genus. Plants formerly referred to P. scrofinoides Peck and P. abscondcns Peck, and so listed by I lard, are now regarded by Peck as varieties of P. serotinus and P. lignatilis respectively. Kellerman and Werner i j). 305 1 include P. acerinus in the list of Ohio plants. This seems to be the only reference to this species in ( )]iio literature. Plants referred by IMorgan to P. niger Schw. were probably V. applicatus. wnich is a rather common species in southwestern Ohio. The ])lants referred to 1'. circinatus by Hard were probably P. lignatilis. He says it may be known by the white gills. The lamellae of T^. lignatilis are white.

The nomenclature in the above key is that employed by Aliss Burlingham in her monograph of the genus in the North Amer- ican L^lora. The genus is commonly known as Lactarius, which Miss Burlingham regards as merely a variation in spelling. L. lactiflua is commonly known as L. volema, and L. rusticana is usually published as L. pyrogala. In these cases both names are given. L. distans Peck, reported by Morgan and Hard, is now re- garded by Peck as a synonym for L. hygrophoroides. L. sordida Peck is a synonym for L. turpi s. L. vieta Fr., L. calceola Berk, and L. zonaria (Bull.) Fr. were reported by Lea and included in Morgan's list. The first has not been otherwise reported from North America. L. cal- ceola was probably an abnormal form of L. hygrophoroides. Of the three only L. zonaria is included in the key and its occur- rence in Ohio is doubtful. L. torminosa has not been reported for Ohio but its range is such as to indicate that it will likelv be found here. flic Ayariiiucai' of Ohio. 525 RL'SSILA I'I'.KS. A.'

Morgan reports R. kitea Fr. but from' his notes it is evident that his plants should be referred to R. flavida which is rather frequent in southwestern Ohio during some seasons. R. lutea has not been otherwise reported and is omitted. Most American plants formerly referred to R. furcata are now more properly referred to R. variata.

Remarkably ocspitose plants referred to this genus by the student should usually be looked for in the genus Collybia. Ohio plants usually known as Collybia lachnophylla are called Maras- mius cohaerens (Fr.) Bres. by some writers. Montague's species have not been recognized by collectors since their publication. The plants reported by ]\Iorgan in the Mycologic Flora as M. fusco-purpureus Pers. were later referred to M. semihirtipes. ]\[. elongatipes was first published as M. longipcs. The latter name was preoccupied. M. siccus, M. bellipes, M. campanulatus and several other species not reported from Ohio are very closely related. The pileus of M. siccus is described as "roseo-pallido" ; that of M. campanulatus as ochraceous-red. A plant with the pileus bright ochraceous is frequent in Ohio. Another with the pileus pinkish to purplish also occurs. In very young plants the stipe is of the same color. l)ut l)ccomes blackish-brown as it matures, be- ginning at the l)asc. tlic apex remaining purplish for some time. AForgan has described this plant as M. bellipes. Even in dried specimens (at least if not too old) the plants can be readily distinguished. Tn this paper the plants with ochraceous pileus are regarded as M. campanulatus, while those with pinkish or purplish pileus are regarded as JM. siccus with M. l)ellipes as a synonym. T.ENTINUS FR.

Lloyd believes it is the plant now known as Clito- cybe monadelpha Morg. and the description bears out the opinion. Peck separated L. spretus from L. lepideus because the lamellae are not sinuate and the spores are smaller. A collection was made at Oxford in 19 10.

Of the 9 species reported from Ohio only 5 occur in Peck's list. It is remarkable that such a dis- parity should occur in states no more widely separated. It is probable, however, that furtlier study of Ohio plants will add a number of species to the Ohio list. 652 Proceedings of the Ohio State Academy of Science. HEBELOM.-V FR.

A brown variety of A. campester occurs but is not common. This species is reported as iisnally occurring from August to October while A. rodmani is said to occur in I\Tay and June. A. xylogenus Mont. (vS. loio). described from Sullivant's material is not an Agaricus in the present limitation of the term. It is probably a yellow form of T.epiota cepaestipes. A. foederatus B. & M. (S. 1003), also described from .Sullivant's material, is said to have the lamellae affixed and the spores brown. It is, therefore, either a Pholiota or a Stropharia. IMorgan refers it to the latter genus. A. fabaceus Berk. (S. 994; M. 11 1), described from Lea's material, is reported common by Morgan, while Lloyd says it has not been recognized in the last fifty years. The pileus was de- scribed as being viscid. A. abruptibulbus is described as white, becoming yellowish in drying. Plants collected at Oxford and referred bv the writer to this species (Ohio Nat. 10: 178) were tawny even when young but had the bulbous stipe of the above species. Plants collected at Columbus in September, 1910, are similar in cverv respect except that the stipe is not distinctly bulbous. These have been referred to A. silvaticus which European writers describe as brown or tawny. The Oxford plants are for the present re- garded as a bulbous form of A. silvaticus. 564 Proceedings of the Ohio State .Academy of Science. STROPHARIA FR. A.^ Piletis viscid or glutinous.
