a la famille des Polyporees le Boletus pachypus, Fr. Bull, Soc. Mycol., France, 
vol. 7, No. 3, Paris, September 30, 1891, pp. 155-157, The presence of starch 
was shown by its reaction with iodine, both in the fungus and when extracted 
by boiling water, and also by its reaction with diastase. The application 
of iodine to sections of the fungus shows that the starch ceases at the pores.

Lactarius piperatus, Scop. Bull. Soc. My col., France, vol. 7, No. 1, Paris, March 
31, 1891, pp. 5-9. Shows the presence of trehalose and the absence of man- 
nite in fresh, young specimens of Lactarius piperatus, Scop. When the Agaric 
is either dried or kept in a fresh state for a few hours the trehalose disappears 
andmannite is found in its place. When, however, the fungus is subjected 
to the vapor of chloroform the trehalose is retained. (E. A. S.)

du Cepe comestible (Boletus edulis Bull.) Comptes Rendus, vol. 113. Paris, 
Nov. 25, 1891, pp. 749-751. After some preliminary observations the author 
describes his method of analysis and states the grams per kilogram of sac¬ 
charine matters found in fresh tissue of the various parts as follows: 
Stipe. (24.5 ) 0.77 
Pileus Trehalose < 13.8 Glucose > 0.71 
Hymenium (tubes) (none. ) none. 
Identical results were obtained with Boletus aurantiacus, Bull. The analyses 
justify the common practice among lovers of Boleti of throwing away the 
tubes and explains the almost exclusive location of dipterous larvae in the 
stipe. In the isolation of trehalose there is a double advantage in using 
only the stipes. (1) the crystallization is easier and the amount greater and 
(2) the fatty matter of the spores is avoided. (E. F. S.)

hand. der k. k. Zool. botan. gesell. in Wien, Bd. 41, ii, Quartal. Wien, July, 
1891, Abh. pp. 581-584. Gives a rdsum6 of the species of fungi reported from 
Valle Lagarina in two previous lists, viz: Ifunghi della Valle Lagarina 
Notizie preliminary in Michelia, 1881, Patavia No. 7; and Elenco sistematico 
degli Irneno —, Disco —, Gastero —, Mixomyceti e Tuberacei linora trovati 
nella Valle Lagarina, in vn Publicazione futta per cura del civico Museo di 
Rovereto. Roverto, 1885. Now adds 53 species, comprising Hymenomycetes, 
Discomycetes, and Myxomycetes. In the two first mentioned families spore 
measurements are given of some species. Gives a summary of the fungi 
now known from Valle Lagarina as follows: Hymenomycetes, 445; Disco¬ 
mycetes, 49; Gastromycetes, 18; Tuberacei, 2; Myxomycetes, 12; total, 526.

1891, pp. 84-86. Discusses the dispersion of spores of Phaloidei and Coprini, 
especially after passing through the stomachs of insects. Shows that there 
is no evidence that passage through the insect is necessary for the germina¬ 
tion of the spore. (M. B. W.)
