eject, in the form of viscous drops or short cirrhi, an orange substance 

 which is very aromatic, and consists of very thin, ovoid corpuscles 

 {spermatin). It is to these alone that the agreeable odour of the 

 Uredo suaveolens and many other Uredines is due. The spermatia 

 are produced at the apices of filiform basidia. 



The Ustilagines, which are very nearly allied to the Uredines, pre- 

 sent certain peculiarities in the vegetation of their reproductive bodies. 

 The oblong cell, which is produced from the spores of Ustilago an- 

 fherarutn, TuL, becoming soon detached to live independently*, must 

 apparently be compared to the secondary spores of jEcidivm, Puc- 

 cinia, and other Uredines above described. In Ustilago receptacu- 

 lorum, Fr., utricles, doubtless analogous with these secondary spores, 

 are produced on an imperfectly developed promycelium, composed 

 only of a few cells, but which resembles that of jEcidium Euphorbice 

 sylvestris.- — Comptes Rendus, June 20, 1853, p. 1093.
