Développement du Scleroderma verrucosum. Par M. Nicotas Soro- 
xing. (‘Annales des Sciences Naturelles,” 1876, p. 30.)—Attention 
is first directed to the two states, thread-like and lash-like, of the 
mycelium, upon which no organs of fecundation were discovered. 
the time the spores are ripening the latter are conve cilage, 
the simple or branched thickened segments remaining. e origin 0

that the spores do not arrive at their full development while attached 
to the basidia, but that they fall off and draw elements of nutrition 
m the nidus in which, when free, they find themselves. 
contrary, he thinks that the spores do not fall until their development 
is complete. He believes also that, contrary to what has already been 
held, there is no regularity in the order of local maturation of the 
hymenial masses. es is sh

no free-cell formation, but a simple division of the protoplasm. ‘After
