U)4 Myrolni^ica! Bulletin No. 49 [Vol. IV 



lialf tones will be preseited in each issue. 'Sly patrons are assured that 

 contributions both in th.e way of notes and photographs will be received 

 ivitli pleasure. It is hoped that portions of letters pertaining to Mush- 

 rooms may occupy a conspicuous place on the "quotation" page. 



Photographs. — Being tl e merest amateur in photography I appreciate 

 the ludricous pose assumed wlen suggestior.s rre ofifered yet (never let 

 on') it may be remarked that the pliotos should be i atural .^'ize or even en- 

 larged unless the Mushrooms are of great size. If ore vvo.ild rtmember 

 also that the printed page is oily four inches wide the illustrations doubt- 

 less would be in most cases adv?ntaged. The height is seldom restricted 

 by page limits. The engraver can reduce the pictures when necessary 

 and in that way obviate loss in reproduction. Enlargement is out of the 

 question unless the photo is unusually sharp and presents sharp contrasts. 

 Characteristic "attitudes," strange habitats, abnormal forms, plants in situ, 

 and other "original" illustrations of mushrooms will be most acceptable. 



With a Long Arm. — The editor will land in that enchanting tropical 

 region of Guatemala the day this Number reaches the subscribers, and 

 therefore the Bulletin will be edited at a disadvantage for three or four 

 months. Some one at home will be commissioned to examine my mail — 

 so the mistakes made in the distribution or other various concerns of this 

 Leaflet, will have attention^ if you will kindly send in your suggestions 

 and criticisms. Reception of the Bulletin will indicate to new subscribers 

 that the annual fee is received — and old subscribers will receive a dun on 



mv return, if 



"QUOTATION PAGE." 



Quotation. — The following interesting article appeared in the Journal 

 of Mycology, and shoud be copied here since the plate has been reproduced 

 in tl e BiLLETiN, see page 193. 



"The Host Plants of Panaeolus Epimvces. Peck. — Panaeolus epi- 

 niyces, first discovered and described by Peck, has been found from time to 

 time more or less abundantly in the vicinity of Madison, Wis. The same 

 .species has been reported near London, Ontario, from when it was sent 

 by Dearness to the Lloyd Mycological Museum. Neilher Peck nor Dear- 

 r.ess mentioned the host plant of this fungus. 



"Peck's description is as follows: Pileus fleshy, at hn-t sub-globose, 

 then convex, wdiite, silky-hbrillose, flesh soft, white or whitish; lamellae 

 rat'er broad, somewhat close, rounded behind, adnexed, dingy white be- 

 coming brown or blackish with a white edge; stem short tapering upward, 

 strongly striate and minutely mealy or pruinose, solid in the young plant, 

 i'ollow in the mature plant, but with the cavit\ small, hairv or substrigose 

 at the base; .spores elliptical black, .nnOP.'-OOoy.V long, .()nn2'-.()n02,5' broad 

 Plant l'-1.5' high, pileus S"-12" liroad, stem .';''-4" thick. Parasitic on 

 fungi. 



"North Grecnbush, November. 



"Specimens found in this region ;igrcc with this description quite 

 closely. The only points of difiference are that the pileus and .spores are 

 larger. The pileus is sometimes over 2 in. Iiroad and the spores run up 

 to .0004' long by .0002S' broad. 



"McKenna, in 1900, studied the nnlerial collected at Madison and 

 identified the host of all the specimer.s found up to that time as Coprinus 

 atramentarius (P>ull.) h'r. Mis material was always found growing in 

 close connection with miinfectcd clumps of C. atramentarius. Upon sec- 

 tioning the thickened edges of the hypcrtro])hied mass of the host, he found 

 the gills and hymcnium well developed. lie also found mature spores 

 which were identical with (hose of C. atramentarius. l<'rom one to seven 

 of the parasitic fruit bodies were found on a single host. 



"On October fi, 1904, four very perfect and well developed specimens 

 of Panaeolus epimyces were found on a shady lawn apparently para- 

 sitic on Coprirus comatus I'>. Several large healthy specimens of the 

 latter were found not more than T) in. distant from any one of the infected 

 forms and no other Agaric was or has since been found growing in that 

 \icinity.
