ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 631 



erumpentia, brevia. Asci cylindracei sessiles, paraphysati, octospori. 

 Sporidia monosticlia ovoidea, septata, muriformia. The author describes 

 one species, P. vitrispora Berl., which grows on the branches of a 

 Californian Lonicera. 



New Mucedineae.* — M. Boudier describes a new fungus Isaria 

 cuneispora, which he finds parasitic on the dead bodies of spiders ; also 

 another new species, Stilbum viridipes, on decaying chips of oak. 



Clathrospora and Pyrenophora.f — Sig. A. N. Berlese follows up his 

 monograph otPleospora J witJIi those of the two allied genera Clathrospora 

 (8 species), and Pyrenophora (27 species). In both genera the primary 

 divisions of the genus are made to depend on the number of septa and 

 on other characters drawn from the structure of the sporidia. 



New Papiilaspora.§ — Under the name P. Dahlise, M. J. Costantin 

 describes a new species of Papulaspora found on the tuber of a dahlia. 

 It appears to be a form of the genus Dactylaria, and produces a number 

 of spherical bodies, somewhat of the nature of sclerotia, which have the 

 power of germination, each cell of the spherule giving rise to a germi- 

 nating filament. 



Schinzia.ll — Herr P. Magnus gives a revised diagnosis of this genus 

 of Fungi [EntorrJiiza Weber), with descriptions of two new species : — 

 S. Aschersoniana, on the root-swellings of Juncus bufonius, and S. Cas- 

 paryana, on the same organs of J. Tenageia. 



Fungus Parasitic on the Plane.1" — ^M. C. Eoumeguere speaks of 

 the ravages committed on plane-trees in the south of France by the 

 attacks of a parasitic fungus Fusarium ramulorum. It is the conidial 

 form of a well-known Ascomycete Calonectria pyrocliroa ; both forms 

 may sometimes be found on the leaves or young branches of the same 

 tree. 



Anatomy of the Common Cedar-apple.** — Mr. E. Sanford states that 

 this species of cedar-apple {Gymnospm-angium macropus) originates in the 

 leaves of the smaller branches of Juniperus virginiana. The mycelium 

 of the fungus causes an abnormal growth in the leaf- tissue, which carries 

 up the apex of the leaf as it developes, and pushes the branch to one side 

 until the knoi itself appears to be terminal. About the 1st of May the 

 mycelium of the fungus collects in masses a little beneath the surface, 

 raising it up into little papillte. Later, the surface of the knot is broken 

 through at these points, and yellow cylindrical masses, composed of 

 spores borne upon long hyaline and more or less gelatinous stalks, are 

 protruded, and when moist swell up, and often extend to the length of 

 nearly an inch. The author then describes in detail the changes which 

 take place in the leaf as the result of the attack of the fungus. The 

 most striking of these is the great multiplication of cells which takes 

 place, and their generally enlarged size.
