ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 495 



Herr C. J. Svendsen * finds, on several arboreal lichens, especially 

 on Xanthorina parietina, a sclerote-forraing fungus, possibly a degraded 

 basidiomycete, to which he gives the name Sclerotium lichenicola sp. n. 



The haricot-bean, Phaseolus vulgaris, is, according to Dr. C. Massa- 

 longo,"f liable to great damage from the attacks of a hyphomycetous fungus, 

 Isctriopsis griseola, which has at present been found only on the leaves 

 and fruit of this plant. 



A hitherto undescribed species of fungus, Oospora Guerciana sp. n., 

 is, according to Dr. F. Cavara,| very destructive to the larvae of Agrotis 

 aquilina, and may therefore be useful to agriculture. 



Herr N. N. von Speschnew § has determined the identity of Phoma 

 nvicola and P. reniformis, which produce the black-rot of the vine. 

 P.flaccida belongs also to the same cycle of development. 



New Genera of Fungi. || — A new American genus of Hydnaceaa is 

 described by Mr. M. J. B. Ellis and Mr. B. M. Everhart, under the name 

 Echinodontium, differing from Hydnum in the thick woody pileus, while 

 the teeth are beset with spines. It is typified by E. tinctorium, growing 

 on Abies grandis (Fom.es linctorius E. and E.) 



Under the name Arcangeliella Borziana g. et sp. n., Dr. F. Cavara % 

 describes a fungus found in the pine-woods of Vallombrosa belonging to 

 the Hymenogastres. The following is his diagnosis of the genus : — 

 Peridium tenue, aegre separabile, basim versus interruptum v. laxe venoso- 

 reticulatum, verticaliter a columella percursum ; basis substerilis pro- 

 ducta, byssa parva donata ; caro fragilis, minute cellulosa, lactiflua ; 

 cellulaa irregulares, e basi radiantes; basiilia clavata, 3-4 sterigmata 

 gerentia ; sporae globosa?, echinulatae ; cystidia adsunt. Fungi gregarii, 

 hypogoei, carnosi, lactifiui. 



A new genus of Phalloideae from Java is described by Prof. 0. Pen- 

 zig,** under the name Jansia, with the following diagnosis : — Receptacle 

 tubular, fusiform, perforated at the apex or closed ; sporiferous portion 

 passing over directly into the wall of the stipe, which is composed of a 

 single layer of bladder-like chambers enclosed on all sides ; sporiferous 

 portion of similar structure, but the chambers open internally, the glebe 

 being composed on the outside of cylindrical prolongations or projecting 

 reticulate bands. 



Engleromyces is a new genus of Xylariaceaa from Eastern Africa, 

 diagnosed as follows by Herr P. Hennings ff : — Stroma superficiale. 

 carnosum, hemispherico-globosum, extus atro-corticatum, intus pallide 

 molle, haud zonatum ; perithecia pluristratosa, plerumque omnino im- 

 mersa, vix ostiolata ; asci clavati, octospori, paraphysati ; sporae ovoideo- 

 ellipsoideae v. late navicularieae ; conidia superficialia, aequalia. 



Two new genera, StieJiospora and Pucciniostele, are described by 

 Herr P. Dietel J J in his account of the Uredineae of Japan. The former
