MICHKJAN ACA1)P:MY OF SCIENCK. 2Srt 



For a low of the papers, a brief uote of comment is aildert, imlicatiiig 

 the scope of the article, range of distribution of the fungi studied, cliaracter 

 of the illustrations, etc., insofar as these are not appar^nt in the citation itself 

 and would l>e of assistance to the student. 



It has seemed undesirable, at least for the present, to attempt to make 

 Ihe list complete for all parts of the world. Only those works arc listed that 

 bear upon groups more or less represented in the United Slates, iKirticularly 

 the eastc>rn half. 



Although the writer is flrmly convinced that the Slime Molds are animals, 

 and that they have no phylogenetic connection whatever witli any group of 

 plants, a couple of standard works on these organisms are listed out of defer- 

 ence to the opinions of the many botanists who still prefer to retain these 

 beautiful little things hi iheir field. They are listed as Mycetozoa, however, 

 not as Myxomyceteae. The Bacteria, although almost certainly true plants, 

 are omitted from this list, inasmuch as tlieir identification requires a training 

 in bacteriology which will at the same time give one acquaintiince with the 

 necessary literature. With Professor Biiice Mnk, the Lichens are believed to 

 be nothing but fungi with algal hosts, not a distinct class, and probably if we 

 shoiild learn their life history fully, many of them not even deserving to be 

 placed in separate orders. Since most of them are still usually placed on a 

 distinct order, the references to these plants will be found under the Order 

 Lecanoi'ales under the Class Ascomyceteae. It is true that this will place 

 such forms as the Pyrenulales apart from their nearest relatives, but that 

 cannot well be prevented in a list of this sort. 



This list cannot be expected to take the place of a general knowledge 

 of the main groups of fungi. To use it to any advantage one must be able to 

 place the organism in the proper class and order, and preferably family also. 

 The student must be able to make use of Saccardo, Engler and Prantl, or 

 Stevens or some other general work, in order to carry the fungus that far, 

 in case his knowledge of fungi has not already progressed far enough to enable 

 him to recognize on preliminary study the group to which it belongs. Then 

 by consulting the appended bibliography it may be seen whether the further 

 steps of identification must be carried to the bitter end by means of Saccardo 

 or whether a monograph or some other work is available on that particular, 

 group. 



As presented, the list shows many lacunae. Many' families, and even 

 orders, are not mentioned. Tliis is due to many factors, viz. : Many groups 

 are still in sad need of critical revision or lie entirely outside of the geograph- 

 ical limits of this paper, or the papers on these groups have been overlooked 

 in tlie compilaticm of this list. It is very pr(ibal)le that many omissions will 

 have to be charged to tlie last head. With the development of the war, much 

 of the foreign literature of the past three or four year^s has been inaccessible, 

 so that for such publications tliis list must perforce be several years behind
