The old Linnean I. lacmtri* is the only species which has been found to ex- 

 tend from the Atlantic to the Pacific States, and it probably occupies a north- 

 ern belt of the northern hemisphere, though it seems not to have been discovered 

 as yet in Asia. The American forms allied to I. cchi>i<>spo:ri,the other north Euro- 

 Dean species, are the most common in the belt of northern States as far west 

 as Michigan, and have been detected also on the western slope of the Rocky 

 Mountains. Of the others, I, Engelmanni extends from Mssachusetts 

 Georgia and westward to Missouri, though thus far not found anywheie else 

 west of the Alleghany Mountains. I.flacdda ispecular to Florida and I. Bol- 

 and&i'i to the lakes of the western mountain chain, the Rocky Mouotains as 

 well as the Sierra Nevada. I. melanoptxhi occupies parts of the Mississippi 

 Valley from Centra] Illinois to Northwestern Texas, while I. NuttaUii is the 

 only species found in the valley of the Columbia river. All the other species 

 seem to be nearly or quite local, L pygmoea, in the Californian Sierra, but 

 most of them on the Atlantic border; thus/. Tuckermani occurs only near 

 Boston. I. mccharata on streams emptying into the Chesapeake Bay, and I. 

 melano&pom only on that peculiar and botanically interesting rock, the Stone 

 Mountaiu of Georgia, Some species which seemed local have lately assumed a 

 little wider range, though yet quite restricted ; among these I mention I. ripa- 

 ria of the banks of the lower Delaware river which occurs als i further north, 

 and I. Bulleri, first known only from the Indian Territory, now also found in 

 Tennessee. There can be no doubt but that some of the apparently local spe- 

 cies will yet be found in a more extended area, when botanists will include in 

 their researches these obscure and inconspicuous plants. 



New Species of Fungi, by Chas. H. Peck.— Hymenoch^ete 

 multispinulosa — Resupinate. dark reddish-brown, the margin 

 paler, the hymenium velvety by reason of the numerous setse. un- 

 even, tuberculose, cracking' into small areas; setas straight or slight- 

 ly flexuous, crowded, .0025-0045 of an inch long, arising from and 

 often persistently attached to the paler filaments of the substra- 

 tum. 



Surface of decaying wood. Arizona, April. G. G. Pringle. 



This fungus approaches, in some respects, the subgenus Velu- 

 ticeps. The specimens are sterile. The color is somewhat darker 

 than that of H. corrugata. 



_ Hymenula Lychnidis. — Minute, punctifof m, disk whitish or 

 pallid, surrounded by a black margin; spores oblong-cylindrical or 

 subclavate, colorless, .0005-0008 of an inch long, .00016 broad. 



Dead or languishing leaves of Lychnis. California, July. M. 

 E. Jones. 



To the naked eye this fungus appears like minute black dots, 

 but when magnified the clots are seen to be the black margin, which 

 surrounds a pale disk. 



Lycoperdon pachydermum. — Subglobose, four to six inches in 

 diameter, the radicating base somewhat pointed,the external peridium 

 thin, smooth, whitish, the upper part cracking into small angular 

 persistent spot-like scales or areas, the inner peridium thick, sub- 

 corky, somewhat brittle, the upper part at length breaking up into 

 irregular fragments; capillitium and spores ochraceous-brown, the 

 filaments long,flexuous, somewhat branched, .0003 of an inch thick:
