ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 751 



In a further paper * they note the prevalence of cereal rusts in 1908, 

 the year having been very damp — in one instance a third of the harvest 

 was ruined. Notes are added on other rusts. 



P. and H. Sydowt have begun the second volume of their work 

 on Uredineae. The first fascicle opens with the genus Uromyces, and 

 contains descriptions of 218 species, arranged according to the natural 

 orders of the host-plants. In most of them only one type of spore has 

 been discovered. The genus resembles Puecinia, except that the teleuto- 

 spores are usually 1-celled, and are furnished with an apical germinating 

 pore. 



J. Eriksson % gives us his recent studies on specialisation in the 

 " coronate " grass rusts. He has distinguished three forms : (1) Puecinia 

 coroniferd, with its tecidium, on Rhamniis calhartica ; (2) P. coronata 

 connected with Mcidium Frangulse, and (3) P. coronata of which the 

 secidium is unknown ; the latter grows on species of Melica. Accounts 

 are given of all the cultural experiments with these different forms. 



P. Magnus § points out that J. Ivar Liro, in the Uredinege Fen- 

 nica3, has included his genus Hyalospora in Uredinopsis. The latter has 

 a pseudoperidium in the uredo sorus which is wanting in Hyalospora, 

 and there are other differences which are indicated. Magnus gives 

 notes on the other genera of Melampsoracese. 



G-. Gassner || records an epidemic of Uromyces appendicidatus on 

 French beans, which practically destroyed the crop. Experiments were 

 made with a number of varieties to test their power of resistance, but no 

 definite results were reached. 



Notes on the Larger Fungi. % — L. Legne describes a Morchella- 

 like form of Collybia velutipes. The hymenium covered the Morchella- 

 like involutions on the upper surface of the pileus. Legne could not 

 detect any parasitic fungus on insects that might have caused the 

 monstrosity. 



F. Hy ** contributes a note in regard to Amanita junquillea, which 

 he finds edible and good, and which has been unnecessarily confused 

 with A. citrina, a poisonous species. A. junquillea is easily distinguished 

 by its fugacious ring, the striate margin of the large pileus and its 

 faint but sweet odour. • 



W. A. Murrill ff records cases of poisoning from eating Inocybe 

 infida, a small dark " mushroom." The medical symptoms are given in 

 detail. None of the cases were very serious. 



Murrill %% also describes a new species of Boletus, " Ceriomyces 

 Maxoni," from Costa Rica, collected at approximately a height of 

 2000 metres among mosses on a rotten log.
