the conidial form of fructification. 3. Sporangial filaments have 

 been traced to the same mycehal tubes as conidiiferous ones. 

 4. Conditions securing the development of sporangial filaments on 

 a mycelium produced from conidia have been in a great degree 

 determined. 5. Prepared Hibiscus decoction exposed to the au* 

 may develoj)e various moulds, but none producing such sporangia, 

 save when ( 'hoanephora conidia have been introduced. Chlamy- 

 dosporous fructification, again, is very rare. According to the 

 detailed observations, then, Chuanephora is a genus of Mucorme 

 Fungi, capable of producing four kinds of fructification, as 

 follows : — 



I. Sexual Fructification . Zygospores. 



(Conidia. 

 Sporangial spores. 

 Chlamydophorous spores. 



These phenomena aftbrd a possible explanation of certain other- 

 wise conflicting conclusions which have been arrived at by such 

 thoroughly competent observers as Brefeld, Van Tieghem, and 

 Le Monnier. At all events it yields a note of warning that 

 classification of fungal organisms, based alone on one form of 

 fructification, mav lead to false conclusions.

Among the recently elected Fellow^s of the Eoyal Society bota- 

 nists will see with great satisfaction the name of Mr. J. Gr. Baker ; 

 a worthy recipient in all respects. 



Mr. William Hillhouse, of Trinity College, author of ' Con- 

 tributions towards a new Flora of Bedfordshire, 1875,' and 

 ' Bedfordshire Plant-List for 1876,' has been appointed Assistant 

 Curator of the Cambridge Herbarium. 



Mr. W. Thiselton Dyer has been elected one of the Exammers 

 in Botany in the University of London. 



We have to record the death of Roberto de VislalNi, which 

 occurred ou May 4tli, at the age of 77. He had been Professor of 

 Botany and Director of the Botanic Garden at Padua for very 

 many years, and his writings extend over a long period, com- 

 mencing, in 1826, with the ' Stirpium Dalmaticarum Specimen.' 

 The Dalmatian flora much occupied him ; his ' Flora Dalmatica ' 

 was published in three vols., with another of plates in 1842-53, 

 and Suj)plements have appeared in 1872 and as recently as last 

 year, 1877. Visiani also wrote on the plants of Egypt, of Greece 

 and of Servia, and was the author of many jmpers in various 

 departments of Botany in the Italian scientific Joiuiials. DeCan- 

 dolle gave the name Visiania to a genus of Oleacece hi 1844, and 

 Gasparrini to one of Ficea:. in the same year, but neither have 

 been maintained.
