one collection from Madagascar with smooth and pubescent specimens in same collection, hence 

 the species based on the smooth pileus is hard to maintain. It is rare, however, for on going 

 through my lot of Stereum lobatum I find only one other smooth collection, which was from 

 Brazil. 



NOTE 366. Lysurus borealis, from Herbert P. Ramsey, District of Columbia. Found in 

 quantities on the Arlington Experiment Farm near Washington, D. C. Formerly this was sup- 

 posed to be a very rare species, but it has now become established in many localities, mostly 

 Eastern. Cleveland and Cincinnati are the furthest west it has yet been found. 



NOTE 367. Polyporus neofulvus, sent by Rev. J. Rick, Brazil. Surface context and pores 

 concolorous, pale yellowish (chamois). Pileus dimidiate, 4x8x1+ cm. Surface glabrous, 

 dull with slightly uneven zones. Context firm, somewhat soft. Pores minute, round, 2-3 mm. 

 long. Cyst. none. Spores abundant, irregular subglobose, 4-5 mic., hyaline, smooth. This 

 plant is close to Polyporous subfulvus as to pores, surface, color and general appearance. The 

 context, however, is concolorous with pore tissue, and in subfulvus the context (almost white) 

 is much paler than surface and pore tissue. Besides the context is more punky, thicker, and 

 the plant is broadly attached, and not disposed to be petaloid. I received it from Re%. Rick 

 before and sent it to Europe, where it was determined as Polyporous nivosus. I satisfied my- 

 self at Kew it could not be nivosus (cfr. note top of page 311, Polyp. Synopsis). Types from 

 Rev. Rick (two collections). 



NOTE 368. Polyporous hispidus, from E. B. Sterling, New Jersey. A fine, large 

 specimen, received fresh. It consisted of several imbricate pilei and measured 7x11 inches. 

 The surface hairs were orange brown, about amber brown of Ridgway. None of the 

 figures in European works show the color of the plant well. Bulliard, t. 493, fig. B., is about 

 as close as any and shows the nature of the hairs better than Boudier's figure. Also 

 color is closer but a little too red. Bulliard, t. 210, is not hirsute enough. Sowerby, t. 345, 

 is too yellow, and Greville, t. 14, much too red. Gillet is much too pale and yellow. The 

 color of the pore mouths is a peculiar, dirty yellow, about olive lake of Ridgway. 



Polyporus hispidus is by no means a common plant in the United States. Mr. Ster- 

 ling finds it on oak in New Jersey, but not many of my correspondents send it in. 



NOTE 369. Polyporus giganteus, from E. B. Sterling, New Jersey. A very large specimen, 

 measuring when fresh 20 inches in diameter. Notwithstanding its name, Polyporus giganteus 

 rarely gets as large as this. Mr. Sterling has an extended article in the Trenton Times- 

 Advertiser, September 19, 1915, on the plant. He states that "when young and tender it is 

 edible." I doubt if Polyporus giganteus is often young and "tender" enough to be of very 

 much value as a food plant. 



NOTE 370. Polyporus borealis, from Wm. C. Stevenson, Jr., Pennsylvania. The form 

 growing upright. In going over our specimens we note an error in our account of the plant in 

 our recent pamphlet. It should be described as "usually growing upright" and reduced at the 

 base, rarely dimidiate, and the flesh spongy when fresh, but drying light weight, but hard and 

 tough. 



NOTE 371. Fomes (Ganodermus) applanatus, from Rev. C. Torrend, Brazil. A large 

 specimen with a thick, distinct stipe. It is usually sessile in the temperate regions. 



NOTE 372. Cordyceps nutans, from A. Yasuda, Japan Collected in Province Chikugo, 

 Japan. The upper portion is orange, while the greater part of the stalk is black. It grows on 

 several species of "Randwanzen." 



I hope my Japanese correspondents will keep a special outlook this season for Cordyceps. 

 I am much interested in them. 



NOTE 373. Leotia atrovirens, from A. Yasuda, Japan. We referred this plant, when 

 received, to Leotia chlorocephala, in sense of Durarid, but on going into the subject again, 

 we doubt if the slight, paraphyse difference between the Japanese specimens and the Euro- 

 pean is enough on which to maintain a species. In addition, it is illogical to apply the nama 

 chlorocephala to a plant with both head and stem green, notwithstanding the evidence of 

 Schweinitz' herbarium, which is not always conclusive, as in the case of Mitremyces lutes- 

 cens (Cfr. Myc. Notes, 30, p. 395). We think we shall take the name chlorocephala for the 

 only plant to which it logically belongs, believing that either Schweinitz or the party who 

 mounted his herbarium has gotten the specimens mixed. 



NOTE 374. Polyporus sambuceus, from A. Yasuda, Japan. Sessile, applanate, 7-13 x 10-22 

 cm. When fresh, juicy and heavy, but when dry it becomes very light, spongy, pithy. Surface 

 with thin, smooth, light brown, separable crust. Context soft, spongy, cottony, white. 

 Pores white or discolored, small, rough, with thin walls, which often split, the pores becoming 

 irregular. Spores globose, 3-4 mic., hyaline, smooth. 



When dry this is a very light, fragile species and closely allied to Polyporus Eucalyptorum 

 in Section 80. In some of the specimens the thin crust has mostly peeled and only fragments 

 remain, in other specimens the crust is indistinct. Prof. Yasuda wrote me it grew on old 

 stumps and is widely distributed in Japan. Two of his collections, Nos. 3 and 311, are typical 

 as described. Two others, Nos. 101 and 235, are probably younger conditions of it. The pores 

 are shorter and regular, the context, while soft and spongy, is not so light and fragile. The 

 surface has no distinct crust. The name adopted is to associate the pithlike context with elder 

 pith. 



NOTE 375. Polyporus orientalis, from Prof. A. Yasuda, Japan. Cfr. Stipitate Polypor- 

 oids, page 193. This specimen is mesopodial, same as the type specimen figured (No. 499). 

 Prof. Yasuda sent some time ago (No. 243) a pleuropodial specimen which I did not recognize
