Glceopeniopliont, which forms gloeocystidia as well as Feniophora-cjstidisi, 

 and Dendrothele, which has thorn-like growths on the fruiting surface. 

 A number of new species belonging to different genera are also 

 described. 



Fomes pinicola Fr. and its Hosts.* — L. EL Pennington has 

 studied the habitat of several of the larger Polypores, more especially 

 Fomes pinicola. He found that it was the most common of the fungi 

 that affect Conifers. The fruiting bodies were almost always found on 

 dead trunks after the wood had become much decayed. On standing 

 trunks they grew near the ground. Occasionally the fungus was formed 

 on the wood of deciduous trees ; in one district it grew abundantly on 

 balsam poplars. The fruiting bodies vary in shape, depending largely 

 on the rate of growth ; the colours of the pileus vary according to the 

 age of the fungus : in some instances on deciduous trees the pileus may 

 be entirely destitute of red and yellow colours. 



Polyporus annosus.f — L. Wittmack publishes a photographic plate 

 and a description of a young fir-tree, sis years old, that bore about 

 middle height a large fruiting specimen of P. annosus. It surrounded 

 the young tree and the branches, which looked as if they had grown 

 through the fungus. In the near neighbourhood there had been an old 

 stump attacked by this fungus, which had spread to the sapling. 



Mycotheca of the Ecole de Pharmacie.l — In a first paper G. Bainier 

 presents a series of observations on the development of several Hypho- 

 mycetes. The rather confused sporiferous head of Periconia is described 

 as bearing a number of globose or oblong smooth basidia, each with a 

 short chain of muriculate conidia. Several forms of Brachycladium and 

 DendrypMum are also figured and described. In the latter genus the 

 author establishes a new subgenus, Dendrypliiopsis, with conidia borne in 

 verticils on the conidiophore. A second paper deals with a new species, 

 Sterigmatocgstsis insueta, entirely dark brown, very minute, and with 

 much-branched conidiophores. 



Chestnuts filled with a dark powder were examined and cultures 

 made, which produced a Hyphomycete, Harziella Gastanm sp. n. Minute 

 conidia are borne at the tips of obpyriform basidia clustered near the 

 apes of the branches. StachyUdium bicolor is also described and figured. 



Bainier describes and figures Sordaria vestita and S. decipiens. The 

 latter species has an 8-spored ascus, and varieties with 4, 16, and 32 

 spores in each ascus, differing from each other in the smaller size of the 

 spores as these increase in number. These spores have an appendix at 

 each end ; at one end, in the form of a mass of small filaments, at the 

 other end, in addition, a long cylindrical cell growing out from the centre 

 of the shorter filaments. 



Diseases and Pests of Coffee.§ — F. C. von Faber gives a review 

 of the numerous enemies of the coffee-plant, both vegetable and animal.
