By the use of gelatinized meat-juice he was able to watch this 

 growth, and to separate Trichophyton from Pen «c/ZZ»m»i,&c., which may 

 have got mixed with it. The author finds no fructification ; and in 

 other respects it differs so much from the ordinary moulds, that it 

 deserves to be separated from them, and in this view Dr. Koch agrees. 



Anthopeziza, a new genus of Discomycetes.* — Dr. R. v. Wett- 

 stein gives the following diagnosis of the new genus Anthopeziza : — 

 Thalamia cfespitosa, magna, longe stipitata, cum stipite flexuoso cornu 

 speciem referentia, superne in cupulam dilatata, e mycelio denso 

 nigrescente (non sclerotio) orta, carnosa, extus imprimis in parte 

 inferiore lanato-pubescentia. Cupula campanulata, margine majus 

 minusve regulariter fisso. Hymenium colore Igeto. Asci longissimi, 

 octospori. Paraphyses tenues, numerosfe, apice clavatfe, inter se 

 irregulariter reticulatim connectfe v. ramosae. Sporre maximae, uni- 

 cellulares, enucleatfe, 3-4 guttulatae. Fungi terrestres, vere prime 

 thalamia proferentes. 



The genus is distinguished from the allied Sclerotinia by the 

 absence of a sclerotium, the branched paraphyses coalescing into 

 bundles, and the size and form of the spores. The species A. Winteri 

 is remarkable for the form and bright red colour of the long-stalked 

 horn-shaped receptacles. It was found on the borders of woods in 

 Lower Austria. 



Conditions for the Development of the Pilaus of Hymeno- 

 mycetes. f — From observations made on specimens of Folyponis 

 squamosus found growing on rotten elm-wood in a dark cellar, some of 

 which were afterwards exposed to the light, while others were kept 

 dark, Prof. E. Sadebeck concludes that the external condition on which 

 mainly depends the formation of the pileus is a sufficient access of 

 light. 



Proliferous Shoots in Hjrmenoniycetes. | — Dr. F. Eichelbaum 

 describes an instance of prolification of the conidiophore in a species 

 of Stysanus, the pedicel renewing its growth, and bearing a secondary 

 head of conidia at its apex. This simple prolification is, according 

 to the author, not very uncommon in the mould-fungi. In Stilbum 

 vulgare he met with a double dichotomous prolification, in which two 

 hyphje had sprung from the original conidiophore, passing through 

 the original head of conidia, and each producing a secondary one at 

 its apex. 



Formation of Conidia in the Hymenomycetes.§ — Dr. F. Eichel- 

 baum points out how frequent is the formation of conidia in many 

 Hymenomycetes, their production being especially promoted by wet 

 weather, and how gradual is the transition from them to the ordinary 

 basidiospores.
