Mycological Notes. III. — F. Petrak {Ann. Mycol ., 1921, 19, 
176-221). The author publishes critical notes on a large number of 
microfungi already known and described. He defines their systematic 
position, adds synonyms and gives biological details. He finds occasion 
to describe a number of new genera based on species already described. 
These are : Neohender sonia, Placonemina, Cucurbidothis, Glaosporidina 
and Discosporopsis. Several species new to science are also described.

J. Bornmuller’s Macedonian Plants : Fungi. — H. Sydow {Ann. 
Mycol., 1921, 19 , 243-54). The plants were collected by J. Born- 
miiller while serving on the “ Landeskundlichen Commission von 
Mazedonien ,” during 1917, 1918. With very few exceptions the fungi 
secured are microfungi, most of them Uredinese, three of which are 
new to science. One Mycetozoon is listed, Stemonitis ferruginea.

Mycological Work of Josef Jahn, a Contribution to the 
Fungus-flora of the Egerland. — F. Petrak {Ann. Mycol., 1920, 18, 
105-35). After Jahn’s death his mycological collections were sent to 
Petrak, who has examined them, and now publishes the results. He 
gives first a sketch of the botanical activity of Jahn, who botanized 
mainly in Eger (Bohemia). Though the list js not a very long one it 
contains some rare species (several of them determined by Petrak are 
new to science) and one new genus, Jahniella (Sphseropsideae). The 
list includes only microfungi. A. L. S. 
Protection against Fungi from Abroad. — N. L. Alcock {Journ. 
Agric ., 1921. October , 28, 5 pp., 5 figs.). The writer calls attention to 
the danger of allowing plants already contaminated with fungus diseases 
to enter the country. The chief source of new diseases to be feared is 
America, as those of Europe have already appeared here. “ Chestnut 
blight,” “ black knot ” of plum and cherry, and “ fire blight ” in apple 
are especially to be guarded against. Descriptions and figures of these 
are given. A. L. S. 
Lichen Parasites and Lichenoid Fungi.— Karl Keissler {Ann. 
Natnrhist. Mus. Wien , 1921, 70-9). The author gives descriptions 
and notes of a number of species, most of them already described. 
There is one new genus and species, Mycarihopyrenia Sorbi Keissl. 
The perithecia resemble those of Arthopyrenia , but without gonidia. 
A useful index of the species referred to in the text is appended.

Longevity of Spores.-- R. Leslie Collett {Trans. Brit. Mycol. 
Soc ., 1921, 7, 217-8). Collett obtained a small portion of a sooty 
deposit on bark issued as Cladosporium fumago in 1854. By careful 
and ingenious treatment, which is fully described, the fungus was 
induced to grow, so that the spores had retained viability for sixty- 
seven years in the dry conditions of a herbarium specimen. A. L. S. 
Sap Stain Fungi. — Ernest E. Hubert {Phytopathology, 1921, 
11 , 216-24, 1 pi., 4 figs.). The author studied two fungi that stain 
wood — Lasiosphseria Pezizula, which produces a grey stain in red-gum,
