98 SUMMARY OF CURRENT RESEARCHES RELATING TO 



tropical lands, from India, Philippines, etc. A number of them are 

 Uredineaj. There is one new genus, Stilbodendron camerunense 

 (Stilbace^e), from the Cameroons. The fruiting bodies are erect and 

 rather long and brightly yellow, and covered the whole length with fertile 

 hypha^ that bear chains of conidia. A. L. S. 



Lichens. 



New or Better-known Lichens. — A. Hue {Ann. Mycol., 1915, 13, 

 73-103). Abbe Hue describes a considerable number of new species, 

 many of them from China and Japan. Most of them belong to the 

 genus Lecanora, as understood by him. Very lengthy and detailed 

 descriptions are given of each species, but chemical reactions are mostly 

 ignored. Several species described formerly by himself and others are 

 emended. A. Lorrain Smith. 



New Lichens. VIII. — A. Zahlbruckner {A7in. My col., 1916, 14, 

 45-61). The present contribution includes twenty-five lichens from 

 Japan, most of them new to science. They are very fully described, and 

 their affinities with other species are indicated. In footnotes the author 

 has given keys to Japanese species of Pyrenula and Hdematomma.

German and Austrian Lichens as Food and Fodder.— C. Jacobi 

 {TilUngen, 3Iohr, 1915, 8vo., 16 pp. ; see also Ann. Mycol, 1916, 14, 142). 

 Owing to war conditions the economic value of lichens had to be tested. 

 The author found that Iceland moss {Getraria islandica) was rich in 

 starch-content and valuable as food, if the bitter principle were removed. 

 Instructions are given how to deal with the plant. He proved also that 

 Gladonia rangiferina., the reindeer moss, was a valuable fodder for pigs.

Lichenes in A Ginzherger : Contributions to the Natural History 

 of Scoglien and the Smaller Islands of South Dalmatia. — A. Zahl- 

 bruckner {Denkschr. K. Akad. Wiss. Wien Math.-Naturw. Kh, 1915, 

 92, 301-22; see also Ann. Mycol, 1916, 14, 142-3). The lichens 

 enumerated (126 species) belong to the " Adriatic Lichen-region," and 

 they are similar to those already collected on the larger islands. Additions 

 have been made of lichens on primitive rocks. Very characteristic 

 species from North Africa were found. As a whole these Adriatic lichens 

 resembled East rather than West Mediterranean forms. A. L. S. 



Morphological and Biological Observations.— K. Goebel {Flora, 

 1915, 108, 311-5). In the mountains of Brazil a species of Ephebaceae 

 was frequently found on stones in waterfalls. The specimens were all 

 sterile, and could not be determined ; the algal cells belonged to Stigo- 

 nema. The noteworthy fact is the unusual formation of haustoria in 

 the hyphae, and their penetration into the algal cells, which were 

 ultimately killed. The fungus in this instance was a true parasite.
