genus are passed under review in the first part of the book, along with 

 results and observations as to germination of spores, development, etc. 

 In the second part he discusses infection and the causes that favour 

 infection and growth. The third part is concerned with combating the 

 mischief. The true dry-rot, MeruUus lacrymans^ is by far the most 

 frequent cause of trouble. 



Comparative Development of Gasteromycetes.* — H. M. Fitz- 

 patrick has taken up this subject, of which very little is known. He 

 obtained very young stages of the fruiting bodies of Phalloij aster sacca- 

 tus, in which he found that the mycelium was compound in structure, 

 being developed as thick cord-Hke rhizomorphs. The different points 

 in formation of the peridial walls, and of the internal structure, the 

 trama, etc., and the final dispersal of the spores, are fully described. 

 A similar careful account is given of a variety of Hysterangium and of 

 Gantiera graveolens. In the latter the gleba is similar to that of 

 Hysterangium, but there is no peridium and the gleba chambers open 

 to the outside. In all of these forms the fruit-bodies arise by the 

 swelling and differentiation of the tip of the rhizomorph ; the peridium 

 is the continuation of the cortex of the rhizomorph. Fitzpatrick dis- 

 cusses at length the theories on the evolution of the different genera of 

 Hymenogastraceae. A bibliography of the subject is added. 



British Mycology.t — The current number of the Transactions of 

 the British Mycological Society is the first part of Vol. IV. It contains 

 accounts of both the spring fungus foray at Worcester and the autumn 

 foray at Forres where a joint meeting was organized with the Scottish 

 Cryptogamic Society. In each case a list of the fungi is given that were 

 collected on the various expeditions, and G. Lister adds a list of the 

 mycetozoa collected round Forres in Scotland, 81 species, one being 

 new to science, and lo others, rare species, new to Scotland.- 



E. Boudier % has described two new fungi found in Scotland, Asco- 

 bolus GarJetonl and Galycella Menziesii, and Carleton Rea has discovered 

 a specimen of the little known fungus, Glischroderma cinctum, which 

 has enabled him to emend the description of the genus and to assign it 

 to its true position in the Plectobasidiue^ near to Tulastomaceas. It is 

 a minute globose fungus, somewhat similar to Lycogala, and was found 

 on charcoal heaps in Worcestershire. 



D. A. Boyd § writes on the fungus-flora of the Moray district, de- 

 scribing the localities as well as the plants. He gives an account of the 

 various workers in that part of the country. He adds that though the 

 average rainfall is about the lowest in Scotland, there is a great wealth 

 of fungi, many of them microscopic in character, both saprophytes and 

 parasites. 



A. Lorrain Smith || draws attention to a forgotten paper by AV. 

 Phillips which contains descriptions of several new species of minute
