 word, to draw the new line of separation of the two divisions as 

 sharply as possible.

 Cassel; Theodor Fischer. ^ The first number will be published in 

 June; and future ones, each to embrace about two hundred species, 

 will follow annually. As there are no plates, the price will be mod-

6t. Unusual Habitat of a Coprinus.— In October, 1880, I re- 

 ceived from Framingham, Mass., a quantity of water which contained 

 a large amount of Coelosphaeritmi Kutzingianum. The water was 

 placed in a clean glass jar and covered with a pane of glass. I had 

 intended to watch the phenomena attending the purifying of the 

 water, which is generally accomplished in about a fortnight, the 

 slimy bluish-green masses of the algae gradually dissolving and form- 

 ing a slight deposit at the bottom of the jar, leaving the water clear 

 above. Contrary to my usual experience, the greenish masses did 

 not disappear, and the contents of the jar remained scarcely changed 

 until early in December. At that date, I noticed spots of mould in 

 several places on the top of the rather thick fluid, and, on examina- 

 tion the hyphae were seen to proceed from small black sclerotia sunk 

 just below the surface. The hyphae, in the course of a few days, de- 

 veloped into small Coprini scarcely more than a quarter of an inch 

 high. On Dec. 13th, being about to close my laboratory for some 

 time, I was obliged to throw away the contents of the jar before the 

 Coprini \\z,A matured, and it was impossible to say with certainty 

 what the species was, although it apparently was a small form of 

 what is figured by Brefeld in Botanische Ufitersiichungen ilber Schim- 

 vielpilze^ Part 3, as Coprinus stercorarius. Although it is possible 

 to raise Coprini on slides in a decoction of horse dung, their spontan- 

 eous occurrence in water containing algae is unusual, and the ap- 

 pearance of the small Coprini as they rose from the surface of the 

 water, which was between five and six inches deep, was very singu- 

 lar. The sclerotia of the C<?/r///^^ were certainly not in the water 

 when first placed in the jar, as they would easily have been seen in 

 the frequent microscopical examinations of the water made in Oc- 

 tober; but the fungi were probably produced from spores remaining 

 from a culture of Coprinus made in the laboratory about six months 

 before the water was received from Framingham. The jar had pre- 

 viously contained a quantity of growing Niiella and was carefully 

 cleaned before the Framingham water was poured into it.

62. Note on Laniinariae.— In the Bulletin foi November, 



1880, there is a note by Mr. F. S. Collins on a Laminaria found on the 

 coast of Maine, and referred by him toZ. longipes, Bory. In his "Ex- 

 amen des especes confondues sous le nom de Laminaria digitata,'" 

 Le Tolls states that an examination of the Borv herbarium showed
