 Naturvidenskab. 56: 137-148. 1 pi., 2 jig., 1 map. 1919. — The author describes propagation 

 by gonidia and by vegetative branching in Pterigynandrum filiforme. His observations are 

 based on field and herbarium studies and on experiments. — A. Gundersen.

 The author's observations are based on material collected by Herzog in the Andes of Bolivia 

 and determined by Stephani as Androcryphia confluens. In some of the specimens he finds 

 purplish red rhizoids, which are not supposed to occur in the genus. He comments on the 

 systematic position of Androcryphia and calls attention to the fact that Stephani makes 

 no mention of it in his published account of Herzog's Hepaticae. — A. W. Evans.

 From the stool, sputum, tongue, etc., was isolated a species of Monilia growing as a yeast. 

 Intra-peritoneal injection into a guinea pig resulted fatally in 7 days. The fungus was 

 reisolated from the liver and gall bladder. — E. A. Bessey.

 genus. Trans. British Mycol. Soc. 6:331-343. PI. 8. 1920.— A species of Melanotaenium 

 was found to be the cause of tumour-like swellings on the subterranean stems and leaf-struc- 

 tures of Lamium album. The fungus is described and named M. Lamii. A study of the 

 cytology of the fungus shows that the hyphal cells are binucleate and the mature spores 

 uninucleate. — W. B. McDougall.

 Missouri Bot. Card. 7 : 81-248. PI. 2-6, fig. 1-48. 1920.— In this continuation of the monograph 

 of the Thelephoraceae of North America, Burt presents a comprehensive taxonomic account of 

 the genus Stereum. The treatment of this large genus of 77 accepted species includes an elab- 

 orate key to the species and under each of the American species discussed there are given the 

 synonymy and references to literature, full diagnoses, notes on occurrence, habits, peculiarities, 

 and citations of specimens examined. The species are arranged in sections as central-stemmed, 

 lateral-stemmed, merismatoid, and dimidiate and effuso-reflexed species. Burt finds the diflfi- 

 culties of identification, experienced by many workers, greatlj' decreased after a thorough study 

 and analysis of the microscopically recognizable organs or combinations of organs. Among 

 the North American species referred to, 12 are new and 5 are newly combined. The new species
