Feb. 1903] Notes from Mycological Literature 
75 
The host is Crataegus oxycantha: Leaves exposed through the 
Winter for the perithecia; and fruit in Fall and Spring, perhaps 
also in Summer. 
Descriptions of American Uredine^:, iv, by J. C. Arthur 
and E. W. D. Holway, Bull. Lab. Nat. Hist. State Univ. Iowa, 
5 : 3 II_ 334 > pl* i~9, Oct. 1902, apply to American plant-rusts in¬ 
habiting species of Graminese belonging to the sections of Agro- 
stidese and Chlorideae, with their accompanying aecidia so far as 
known. Sixteen species are included, Puccinia muhlenbergiae 
being new. Only one of the species has had its full cycle of 
development traced, namely Puccinia fraxinata (Lk.) Arthur of 
which Aecidium fraxini Schw. is the alternate form. The orig¬ 
inal diagnoses, also new and very full description and critical 
notes, as well as illustrations are given, as in previous numbers 
of this series. The article is based on the material in the authors’ 
Uredineae Exsiccatae et leones. 
In Beiblatt zur Hedwigia, 4i:(i69), (177), (179), Sept. 
— Okt. 1902, (Heft 5.) we find the following mycological titles: 
Eine neue norddeutsche Phalloidee (Anthurus borealis Burt var. 
n. Klitzingii P. Henn.), von P. Hennings; Einige Uredineen aus 
Japan, von P. Dietel; Die Befruchtung von Albugo Lepigoni 
und einigen Peronosporeen, von W. Ruhland. 
Articles relating to Fungi in Hedwigia, Heft 4, 1902 (p. 
164, & 167) are Einige neue deutsche Pezizaceen, von P. Henn¬ 
ings ; Eeinige neue Cordiceps — Arten aus Surinam, von P. Hen¬ 
nings. In the Beiblatt to the same are, (p. 145) Bemerkungen 
zu Dieteks Ausfiihrung fiber die Gattung Uropyxis, von P. Mag¬ 
nus; and (p. 146) Phlebia Kriegeriana P. Henn. n. sp., von P. 
Hennings. 
Collecting and Preserving Fungi, Uredineae, is briefly 
treated by E. W. D. Holway in Jour. Appl. Micr. & Lab. Meth. 
5 12075-6. 1902. It is suggested that a portfolio with many thin 
sheets and but few dryers be used — though a botanical box is 
convenient in the wind or where very large quantity is to be taken. 
Leaves of grasses and sedges to be cut in 4 inch pieces; some 
ligules and inflorescences should be collected; search specially for 
the uredo stage also ; collect aecidia when not too old, use but 
little pressure in drying them. Determine hosts accurately. 
Arrange the specimens in a large herbarium according to the host 
plant, putting different genera on different sheets. Have a set 
of mounted slides — Dr. Arthur’s method, i. e. spores mounted 
dry, the cover glass fastened with a narrow strip of gummed 
paper. 
Frank Lincoln Stevens in Studies in the Fertiliza¬ 
tion of Phycomycetes, Bot. Gaz. 34:420-5, Dec. 1902, says 
that “the general bearing of the cytological evidence on the re-
