628 SUMMARY OF CURRENT RESEARCHES RELATING TO 



poisonous or worthless fungi which are often mistaken for them, has 

 been issued in pamphlet form by the Trustees of the British Museum. 

 The drawings are reproduced on a reduced scale from a beautiful series 

 by W. G. Smith which is exhibited in the Department of Botany, and 

 are accompanied by a descriptive text. 



Notes on the Larger Fungi. — A further series of coloured plates 

 of edible fungi have been printed,* with descriptive letterpress. These 

 are Craterellus cornucopioides, Lycoperdon giganteum, and Boletus edalis. 

 Notes are given as to the methods of cooking;- 



In a further issue of the Journal f two species of poisonous Agarics 

 are figured and described : Amanita mappa, which is easily avoided as it 

 has a strong unpleasant smell, and A. pantheri/ia, which has a dusky 

 brown cap covered with whitish warts. Both of these grow on the 

 ground, chiefly in woods. 



Wilmer G. Stober | gives a list of the larger fungi found near Oxford, 

 Ohio. He adds descriptive notes ; the species are all American. 



W. A. Murrill § publishes a coloured plate and descriptions of ten 

 species of Myr/rophori, the most common species in the United States. 

 Eight of them are also common in Great Britain. 



Distribution of Poisons in Mushrooms. || — W. W. Ford has investi- 

 gated several species of Amanita to test their poisonous qualities. He 

 found that in a carefully prepared extract of Amanita phalloides there 

 were two poisons : amanita-hasinolysine, a glucoside, and amanita-toxine, 

 which is the more poisonous. He found the same substances in A. virosa, 

 A. spreta, and A. verna. Other species that he examined contained a 

 similar toxine, but no hagmolysine ; they are, none the less, deadly 

 poisonous. A. Frostiana, considered to be a variety of A. muscaria, 

 was found to be without either of these two poisons, and Ford con- 

 cludes that it cannot be nearly related to A. muscaria. 



Chilian Fungi. t" — C. Spegazzini has described 326 species of fungi 

 for Chili, very little having been known previously of the fungi of 

 that region. He has found many new species, and these are de- 

 scribed in Latin. Critical notes in Spanish accompany most of the 

 species. The new genera described are Physalosporella and Parantho- 

 stomdla^phsevi&cese) ; Sphseronemopsis{SphasTapsides&) ; Lophodermopsis 

 (Lophostomataceae) ; Stemphyliopsis, Volvtellopsis, and Myriophy sella 

 (Hyphomycetes). 



Servian Fungi.** — In preparing the list of fungi for Servia, 

 N. Ranojevic describes the journeys that he undertook in the neigh- 

 bourhood of Belgrade at different times of the year, and longer travels 

 to more distant regions. He has collected or identified G47 species,
