60. Lichens or Fujigi ?— I wish to ask the attention of botanists 

 interested, to a forthcoming work of great research on the limits of 

 the two classes named above. Dr. Arthur Minks of Stettin.Prussia, has 

 already, by his " Contributions to the Knowledge of the Structure 

 and Life of Lichens" {Beitriige, etc., pp. 126, and 2 plates, 1876), 

 and especially by his larger work on ''The Microgonidium " (pp. 

 250, and SIX plates, 1879), conciliated the thorough respect of all 

 uiiprejudiced lovers of science. He has now begun another under- 

 taking which appeals to mycologists even more than to lichenists. 

 1 he evident approaches between the vast realm of the Fungi and the 

 smaller, but higher and more readily comprehended domain of the 

 Lichens, have been explained in such a way that, while a great 

 deal remained evidently unsettled, the lichenologist gained the ad- 

 vantage of understanding after some fashion his position, while the 

 mycologist (I venture here to speak from my own correspondence) 

 found himself often in doubt, and without, it seemed, any sufficient 

 criterion of judgment. It is surely interesting then, that, taking his 

 departure from the essential distinction (as he undertakes to demon- 

 strate it to be) between the iheca of Lichens and i\it ascus of Fungi, 

 Dr. Minks finds himself now in position to declare that the boundary 

 line separating the Lichen-world from that of the Fungi runs far with- 

 in the present limits of the latter; and that we are henceforth to look 

 not (with Sachs, Le/irbitc/i, edit. 3, p. 26O) towards an ill-assorted

Many thousands of species of so-called Fungi are thus to be elevated, 

 or re egated to the other class; and a most important step in this 

 way taken towards the removal of manifest, and not by every one 

 approachable, difficulties of the System of Plants
