BERLESE, ICONES FUNGORUM. 
represent, and the measurements of the sporidia given, purport to 
be derived from original sources. We have often urged that 
systems may change, names may be superseded, but good and 
faithful representations, executed from authentic and well deter- 
mined specimens, will last for ever. Whatever our individual 
opinions may be of the limits of genera or species, this does not 
affect the value of a work of this kind, which was worth doing, 
and worth doing' well. We regret to observe so many illustrations 
of fungi, in all orders, ’which have been issued of late years, fail- 
ing in their object, because roughly or imperfectly executed, or 
because drawn from specimens not well authenticated. Our author 
has evidently appreciated these failures, and set himself at work 
to escape any such charge, and in this he seems to have succeeded. 
We wish him well in his useful and arduous undertaking, and trust 
that he will continue to pursue it in the same spirit to the close, 
At p. 86 is a rather long list of described species of Lepto splicer ia, 
which at present could not be figured for lack of authentic 
material. Let us hope that mycologists will assist Dr. Berlese in 
his laudable enterprise, by communicating authentic specimens, 
so that many of these may yet find a place in the promised 
" Appendix.”
