558 SCIENTIFIC RECORD FOR 1882. 



Fungi Gallici and Fungi Veneti by Saccardo, who has, in addition, 

 issued parts 28 to 32 of his Fungi Italiei Delineati. In Hedwigia are 

 descriptions ot new Ascomycetes by Eehm, and new Sordarice bj' Oude- 

 mans. Bainier, in his J^tude sur les Mucorinees, describes several new 

 species of that order, and Blytt describes a new species of Myxomy- 

 Cetes, Clastoderma Be Baryanum. The development of the sclerotium of 

 Peziza sclerotioruni has been published by Mattirolo in the Giorn. Bot. 

 Schroeter has notes on the genus Physoderma in the Bericht Schles. 

 Gesellsch. Fungi rom South America have been described by Speg- 

 gazzini; from Australia by Cooke, and from the Cape of Good Hope by 

 Kalchbreuner, the last two of which appeared in Orevillea. The Revue 

 Mycologique contains numerous notices of fungi by Roumegufere, includ- 

 ing notes on the species included in Fungi Oallici Fxsiccati, which has 

 reached the " 24th century." 



Of works relating to the diseases of plants caused by fungi should 

 be mentioned R. Hartig's Lehrbuch der Bauml-rankheiten. Michelia 

 contains an elaborate article by Penzig, Funghi AgruynicoU, in which 

 he describes all the species of fungi known by him to be parasitic on 

 different species of Citrus. The diseases of grape-vines have been 

 treated by Millardet, Thuemen, and Comes. In his paper on PourridiS 

 et Phylloxera, Millardet ascribes the rotting of vines at first attacked 

 by Phylloxera to the growth of Rhyzomorpha fragilis, whose action 

 on the roots and young stems he describes and figures. Thuemen 

 ascribes the origin of the rotting of the roots to the moisture in the 

 ground. Comes considers what is known in Italy as the Mai Nero to 

 be a gummy degeneration like similar diseases in the Amygdalece. 

 Prillieux, in the Compter Rendiis, describes the change produced in 

 grapes by mildew. Marshall Ward presented to the Linnsean Society 

 the results of his later observations on the coflee-leaf disease, giving 

 still stronger reasons than before for considering the fungus Eemilda 

 vastatrix to belong to the Uredinece. Prillieux regards the rot of 

 grapes as caused primarily by Peronospora viticola, and states that 

 Phoma uvicola follows, but is not the cause of the disease. He also 

 notes the occurrence of disease of beets in France caused by Pero- 

 nospora ISchachtii. Of works relating to disease in animals caused by 

 plants of a higher grade than bacteria, we should mention the Actino- 

 mykosis des Menschen, in which Ponfick describes and figures a species of 

 Actinomyces, which attacks primarily the lower jaw in man, causing a 

 disease similar to one already known to occur in cattle. The diseases 

 produced by the growth of species of Aspergillus is the subject of a 

 paper by L, Lichtheim, in the Berlin Klinischc \VochenscJirift. 



Algce. — Among the more important works on the development and 

 general structure of algse should be mentioned the Chromatophoren der 

 Algen by Fr. Schmitz, in which he gives an account of the morphology 

 and development of the colored body in the cells of algse. These
