A discussion of Fuenfstueck's and Zahlbruckner's 
treatment of Lichens in the Pflanzenfamilien is given by Al¬ 
bert Schneider in the May Torreya (1905) under the title: The 
Classification of Lichens. They are not recognized as an autono¬ 
mous group by all. There is great confusion with regard to the 
delimitation of lichen species. The number of good species 
(continues the author) is in all probability less than one-fifth 
•of those actually described. The system of classification proposed 
by Zahlbruckner is excellent and should be generally adopted. 
A list of twenty additional species is given by G. A. 
Reichling in Torreya, May 1905, as Contributions to the recorded 
Fungi and Slime-Mould Flora of Long Island. 
George Massee gives an interesting account of A 
Fungus parasitic on a Moss, in Torreya, March 1906. It occurs 
on Weisia viridula, the capsule of the moss under normal con¬ 
ditions being usually erect and symmetrical, when attacked by 
the parasite however it becomes distinctly curved and unsym- 
metrical. The description is under the following name: Epicoc- 
cum torquens Massee n. sp. 
Fungi Columbiani, Century XXI, by Elam Bartholo¬ 
mew, is dated March 20, 1905. The following new species are 
included: Cladosporium nervale Ell. & Dearn. on living leaves 
of Rhus typhina; Diaporthe ostryigena Ell. & Dearn. on trunks 
and branches of Ostrya virginica; Haplosporella conmixta Bar- 
thol. on fallen limbs of Ulmus pubescens; Polystigma adenosto- 
matis Farlow n. sp., on living leaves of Adenostoma fasciculatum; 
Dichromera prunicola Ell. & Dearn. on Prunus virginiana, and 
Sphaeropsis magnoliae Ell. & Dearn. on Magnolia (acuminata?). 
In this country the genus most largely represented is Puccinia 
with 26 pockets; there are 5 Uromyces, and 7 Septorias. 
Some Factors in the color production in a species of Fu- 
sarium is discussed by Dr. J. B. Pollock, in Science N. S. 
231422-3, Mar. 16, 1906. The Fusarium taken from an ear 
of corn was under culture found to develop its bright salmon- 
pink only in bright sun light; moisture also is of significance — 
the moister the medium the less the color showed. Color varied 
on media of different constitutions — pale on cornstarch; on 
carrot, Hubbard squash and cornmeal the color was between 
roseous and testaceous (Sacc. Chrom.) ; on apple, onion and 
potato, almost exactly ochraceous; on wheat flour slightly paler 
than orange; on buckwheat flour it was darkest red, slightly 
redder than testaceous, on raw dahlia tubers bright red, but 
almost no color produced if the medium is steamed — and the 
fungus produced a green color. 
In respect to the Parasitism of Neocosmospora, Howard 
'S. Reed shows, in Science N. S. 23:751-2, May 11, 1906, that
