PUBLISHED FASCICULI. 



The great number of published Fasciculi of Cryptogamia which 

 have been issued during the past year, and are being continued in 

 the present, has caused us to come to a decision as to the publica- 

 tion in this Journal of lists of species contained in such fasciculi. 

 With every desire to assist the energetic cryptogamists who are 

 issuing these fasciculi, it would be clearly impossible to publish 

 lists extending to at least a thousand species in one number of 

 " Grevillea;" and to publish some and exclude others would be 

 manifestly unjust. Hence we have resolved not to publish lists of 

 any of the Fasciculi which are issued on the Continent ; but, pro- 

 fessing as this does to be a British Journal devoted to the interests 

 of British Cryptogamists primarily, we reserve to ourselves the 

 liberty of publishing lists of the Fasciculi published in Great 

 Britain, should we at any time consider such a course desirable. 

 This explanation is necessary in order that it may be understood by 

 our correspondents abroad that the publication of British lists 

 cannot be accepted as a precedent for the insertion of lists of the 

 species contained in Fasciculi not issued in Great Britain. 



Rabenhorst's Lichenes Europcei Exsiccati. — We would call 

 attention to the publication of the xxxvth fasciculus of this work, 

 which has recently appeared, and contains numbers 926 to 950. 



Rehm's Cladonien, Fasc. ii., has also just appeared ; and the 

 Eev. W. A. Leighton informs us that the specimens are, as in the 

 fonner fasciculus, exceedingly excellent, both in quantity and pre- 

 servation, and are carefully mounted and named after the latest 

 authorities and revisions. The reactions are noted as found. The 

 fasciculus contains fifty specimens, from number 51 to 100. 



Pkof. Oudeman's Fungi Neerlandici, Cent, i., has appeared 

 since our last issue, and is valuable as illustrating the Mycologic 

 Flora of a portion of Europe, from whence no collection has pre- 

 viously issued. 



Saccaedo's Mycotheca Veneta, Cent. iv. to vii., have also 

 been published, equalling the previous centuries in quality and 

 quantity. Although we cannot agree with Professor Saccardo as 

 to the advisability of adopting a host of the modern genera, and 

 holding peculiar views as to the limits of some others, in such a 

 work as the present, where he has no means of explaining his 

 views, his collection will be acceptable. We need go no further for 

 an illustration of our meaning than the first three specimens : No. 

 8(>1, Periconia chlorocephala, Fres. ; No. 302, Periconia jyycnospora, 

 Fres. ; No. 303, S])orocybe byssoides, Bonord (non Berk.). It is 

 not every mycologist who has so strong a faith in Bonorden's 

 infallibility.
