Michigan. No less than four of these interesting species belong 
to the genus Agaricus.

Carolyn W. Harris outlines and illustrates the Lich¬ 
ens Collema and Leptogium in the May No. of the Bryologist, 
1904. The two genera are described; and four species of the 
first and six of the last are enumerated. They are found in the 
same localities and common — readily separated by the amateur 
since the under surface of Collema is devoid of rhizoids but in 
Leptogium they are always present in some form. 
P. Magnus is the author of an interesting paper, Ein 
Weiterer Beitrag zur Kenntnis der Gattung Uredinopsis, Hed- 
wigia, 43:119-125, PI. I-II, 24 Mar. 1904. The literary history 
of the several species is noted, and attention is called to the fact 
that Uredinopsis americana Syd. n. sp. Ann. Mycolog. 1 1325, 
1903, auf Onoclea sensibilis is the same thing as listed in Far- 
low’s Host Index as follows: 
Septoria mirabilis Peck. 
Uredo macrosperma Cooke. 
Gloeosporium phegopteridis Pass. 
Melampsora scolopendrii (Fckl.) Farl. 
and should be designated as Uredinopsis mirabilis (Peck) P. 
Mag. (U. americana Syd.). A new species on Aspidium thelyp- 
teris, collected by Geo. F. Atkinson, at Ithaca, N. Y., is named 
Uredinopsis atkinsonii P. Magnus, and still another from same 
locality and collector on Osmunda cinnamomea is given as Ure¬ 
dinopsis osmundae P. Magnus. Two lithographic plates illus¬ 
trate the three species. 
The mycological articles in Hedwigia, Band XLIII, 
Heft 2, to be mentioned are: P. Hennings, Zweiter Beitrag

E. Ule collecti, and Einige Pilze aus Japan (Anfang) [three new
