[Vol. 10 
Annales Mycologici, vol. II. No. i, Jan. 1904, contains 
the following articles: Copeland, New and Interesting California 
Fungi; Petri, Naucoria nana sp. n.; Saccardo, Notae Mycolog- 
icae; Dietel, Ueber die Uredineengattung Pucciniostele Transchel 
et Komarov; Sydow, Neue und kritische Uredineen; Rehm, As- 
comycetes Americae borealis; Hohnel, Mycologische Fragmente, 
Fortsetzung; Vuillemin, Le Spinellus chalybeus (Dozy et Molken- 
boer) Vuillemin et la Serie des Spinellees; Salmon, Cultural Ex¬ 
periments with the Barley Mildew, Erysiphe Graminis DC. 
Ascomycetes Americae borealis, autore Dr. H^JRehm, 
Ann. Mycolog. 2 :32~7, Jan. 1904, includes notes and descriptions 
of 16 species of Discomycetes, nearly all of which are new and in¬ 
teresting, collected by Lloyd, Durand, and Harper. 
Neue und kritische Uredineen, II, von H. u. P. Sydow, 
Ann. Mycolog. 2127-31, Jan. 1904, includes five new North Ameri¬ 
can species belonging to the genera Gymnosporangium, Phrag- 
midium, Uredinopsis and Uredo. A Gymnosporangium occurring 
on Libocedrus decurrens, California, was referred to (not de¬ 
scribed) by H. Mayr in “Die Waldungen von Nord Amerika” 
(1890) as “G. libocedri”—then (in 1898) referred to Phrag- 
midium libocedri P. Henn. n.sp. by the latter mycologist. But 
the specimens destroyed by insects, spores not examined, etc., the 
Messrs. H. & P. Sydow think “so ist G. libocedri am besten ganz 
zu streichen.” Their species, G. aurantiacum, occurs on the leaves 
of the host named—but Mayr’s bildet Anschwellungen an den 
alteren Zweigteilen. Sydow’s species and Hennings’ Phragmid- 
ium may be the same thing, according to the former authors. 
ELEMENTARY MYCOLOGY. 
W. A. KELLERMAN. 
It is intended to furnish a series of paragraphs for those 
who may wish to take up the general study of Fungi. It will 
be a brief as well as elementary treatment of the subject, calling 
attention first to the great number and varied character of the 
plants included in this group, their general structure and mode 
of life, and then giving an outline of the groups with such illus¬ 
trations as may seem desirable for the needs of beginners. 
Mycology. — This term is formed from two Greek words, 
my-ces meaning mushroom or fungus, and logos. The real or 
original meaning of the first Greek word is slime or mucus — and 
of course was used to designate these plants — or the peculiar 
material which in the early days was not really understood and 
not at all supposed to be closely allied in fundamental structure 
and mode of life to our common plants. Some of the plants
