The author gives a list of fungi collected in Smaland (Sweden). About 100 species of 
Uredinece, 30 Peronosporacece, and 19 species of Perisporiacece are enumerated. No new 
species are recorded. (Theo. Holm.)

nomenes de parasitisme. <\Le Botaniste, 2 e s6r., Paris, 12 A6ut 1891, pp. 
232-264, pi. 4. 
The author divides the memoir into three chapters, the first relating to parasites found 
upon marine alg;e growing in the maritime laboratory of Luc-sur-Mer, the second to diseases 
found in the cultures of fresh water algae, and the third to a few diseases of lower animals. 
In Chapter 1 are described, with figures, Ciliophrys marina n. s. (saprophytic) arid Aphelidium 
lacerans De Bruyne (parasitic) on Ulva lactuca, and Olpidium aggregatum n. s. bn Cladophora 
marin, notable as being a member of the family Chytridiacece on a marine alga. Chapter II 
treats of t he monadine, Endomonadina concentrica nov. gen., nov. sp., producing an epidemic 
disease of Palmella hyalin a (?); of Minutidaria elliptica. n. s. on alga undetermined, which, 
together with the Chytridium destruens Nowak, placed by Dangeard in Minutularia. form 
a small genus by themselves on Draparnaldia glome rata, causing a true epidemic Chy¬ 
tridium mamillatum Braun, on Conferva bombycina; Chytridium assymetricum, n. sp. on 
Zygnema,- C. sphcerocarpum <Rhizidium , Zopli) on Zygogonium,- Micromyces zygogonii, 
Dangeard, on divers algae, Osc.illarias and Nitellas; Gyrnnoplirydium hyalinum, n. g., n. sp. 
,on Eu'jlena,- Nuclearia minima, n. sp.. N. delicatula Cienk, and Plat.oum ( Clamydophrys) 
stercoreum, Cienk, on Closterium; Antlea Closterii , n. g., n. s., Nuclearia simplex Cienk. 
and Bacillus closterii, n. sp.. are also described. Chapter III describes the following dis¬ 
eases; Harposporium anguillvlce Bolide, on Anguilhe, and abacterial disease of Ophrydium 
versatile, which suggests to the author that the struggle between the nucleus of the cell 
attacked and the bacteria is prolonged by the former’s peculiar long ribbon shape. Throws 
out suggestion that the nuclei of the cells of fungi and higher plants, as well as of animal 
cells, are principally storehouses of food for the surrounding protoplasm, and the protoplasm 
dies only when the stock of nutriment in the nucleus is exhausted. (D. G. F.)
