The sporidia of Chatomium murorum have a chink on one side, 

 like those of the Spharia pedunculata, Dick., and S. Mppotrichioides, 

 Sow. 



The true structure of Sphtcronema is delineated in a species which 

 grows upon the buds of Dahlias, which is almost identical with S. 

 blepharistoma, figured in Mag. Bot. and Zool., vol. i. 



The reproductive bodies of Tuber are beautifully figured, under 

 Tuber fuscum. In the common truffle we find them just the same, 

 and by no means such as represented by Turpin in his memoir on 

 that genus. 



The last illustration is perhaps the most important, being a com- 

 plete confirmation of the views on the structure of hymenomycetous 

 fungi, published in a late number of this journal *. It is most curious 

 that Ascherson, Corda, Montague, Leveille, Brogniart and Decaisne 

 should almost at the same time have observed the true structure of 

 the hymenium in typical fungi. 



It will not be thought invidious, if after calling attention to so 

 many points of interest, (and there are many which we have not no- 

 ticed,) we point out a few matters which might mislead. The au- 

 thor is certainly too hasty in the proposing new species and genera : 

 indeed, many of his species appear to be the conidia of other fungi, 

 or anomalous forms of described species. Bispora intermedia appears 

 to be a correctly drawn Torula antennata. Halysium atrum is Spilo- 

 ma melanopum, E. B. t. 2358, which has been neglected by authors- 

 Its nature is still doubtful. Periconia byssoides is either incorrectly 

 drawn or is not the true plant of Nees, the flocci of which are arti- 

 culated and the spores curiously granulated. 



The species figured as Stilba appear to belong to other genera. 

 Stilbum crystallinum is clearly Aspergillus albus, and Stilbum vulgarc 

 certainly not the true plant. Stilbum nodosum appears to be young 

 Aspergillus maximus. 



Other points might be noted, but we had rather again call the at- 

 tention of our readers to the merits of the work, and recommend it 

 very strongly to their patronage.
