accustomed, and begins with the sub-genus Pleurotus, continuing with 

 Omphalia, Collyhia, Mycena, etc. 



Underground Fungi of Hungary.* — L. Hollos chronicles 68 such 

 fungi in Hungary, among which one genus with 3 species belong to the 

 Hemiasci, nine genera with 40 species to the Ascomycetes, and ten genera 

 with 25 species to the Basidiomycetes. Most of the species are found 

 all over the Continent. Special attention is devoted to the edible forms : 

 the truffle and others. The paper is well illustrated by coloured plates, 

 which give the natural habitat as well as microscopic details. 



Mycological Notes. f — C. Gr. Lloyd has issued a synopsis of the 

 section Ovinus of Folyporus. In this he includes the stalked species, 

 though some of the species discussed lack the stipes in abnormal cases. 

 Polyporus ovinus itself is a common plant in the pine woods of Sweden, 

 but has not been recorded from England. It is a dull white plant about 

 3 to 4 inches across the pileus. P. confluens differs in the reddish colour. 

 P. squamosus, very common in Europe, is rare in the United States. 



Teratological formations in Fungi.^ — P. M. Biers describes a case 

 of a Boletus on which two others were superposed. He explains the 

 malformation as resulting from the adhesion of species growing in close 

 proximity. The first of the three to develop carried up the other two, 

 the heads having become attached. 



F. Gueguen § records a case of attachment in Glitocyhe nehularis, one 

 of the two individuals seeming to grow out of the pileus of the other. 

 He finds that union can only take place at a time when the tissues are 

 still plastic. After differentiation, such attachments are no longer 

 possible. 



Poisonous Fungi. — Radais and Sartory |1 have examined the poison- 

 ous principle of Amanita phaUoides. They find, after having extracted 

 the sap for a considerable time, and macerated the tissue, a solution 

 in water was as poisonous as at the beginning. Boiling water was 

 equally ineffectual in removing the poison. Plants kept in the herbarium 

 retained the poisonous quality unimpaired for a year, and it was still 

 present after ten years. The authors desire to disabuse people's minds 

 of the idea that poisonous fungi can be rendered harmless by soaking or 

 boiling in water. 



Ferry If has published a volume on Amanita phaUoides with the var. 

 verna, and also including A. virosa. The botanical description of the 

 species is given, synonymy, distribution, etc. The second part contains 

 a treatise on the poisons of these plants. One of the poisons, hemolysin, 

 is found also in A. ruhescens, but it is destroyed in the process of cooking 

 the funffus.
