Journal of Mycology 
[Vol. 10 
The descriptions of new genera constitute the bulk of the 
compilation, but new generic names are likewise included; we 
give also all names and diagnoses of larger groups, as sections, 
families, etc. In fact, no new group names or descriptions are to 
be omitted, and the Slime Moulds, Fission Fungi, and Lichens 
are included. This, together with the complete Index to North 
American Mycology by the senior author, where are given full 
citations for species, hosts, etc., should furnish the student and 
the working mycologist a ready and perfect guide, as well as 
compendium of considerable usefulness. 
The names are arranged alphabetically for convenient ref¬ 
erence and placed under the commonly accepted large groups 
named below. The genera of the Laboulbeniaceas are separated 
from the Ascomycetae; so also the Aecidiomycetse—comprising 
the Smuts and Rusts — are given as a separate group. The Lich¬ 
ens are not listed separately but placed where they structurally 
belong with the Fungi proper. The “imperfect fungi” are listed 
as the Deuteromycetse. The sequence in the list is as follows: 
I. Myxomycetae. 
II. Schizomycetas. 
III. Phycomycetae. 
IV. Ascomycetae. 
V. Laboulbeniineae. 
VI. Aecidiomycetae. 
VII. Basidiomycetae. 
VIII. Deuteromycetae. 
The abbreviations n. n., n. g., n. subg., n. sec., n. fam., etc., 
will be used instead of the full words new name, etc. The Fam¬ 
ily or special group to which the new genus, etc., belongs, will 
be reproduced when possible in the form given by the author. 
The citation includes the Full name of the volume or periodical, 
with date given on title page of the Volume, Number, Part, Heft, 
etc. The common American mode of citation of the volume, 
number of the page and date is followed, according with Library 
rules except that dates are indicated in an unambiguous manner. 
For still greater convenience the name of the large group 
is given immediately above each description. This plan will be 
appreciated when the compilation becomes very much extended. 
In case the Separates are cut up and the paragraphs attached to 
library cards this group designation will prove indispensable. 
Since the date is always given in the first or second line, it will 
be possible, when desired, to arrange the names in a chronolog¬ 
ical order. 
All authors of new genera or other groups of fungi and 
those who propose new names are earnestly requested — when the 
periodical is not taken by practically all libraries and botanists —
