ana Miscellaneous Jramcuiars. 
2474. Ozonium. We presume, from o^o;, a branch, in allusion to the manner in which the filaments branch 
or diverge from a common centre. This genus has been extracted from Dematium by Link. 
2475. Rhizomorpha. So called from its resemblance to the branching fibrous roots of various plants. All 
the productions referred to this genus are very obscure and uncertain. R. phosphorea, the Clavaria phosphorea 
of Sowerby, is a plant sometimes existing as a parasite between the wood and bark of trees, or in wine-cellars 
among saw-dust, and is, when fresh, remarkably luminous in the dark. 
2476. Sepedo7iium. From (TijtcSw, putrescence. The species grow among the decaying parts of funei and 
other putrid substances. 
2477. Acremonium. From nx^ifAuv, a branch ; the thecaa are produced about the filaments in fascicles, as 
branches are about trees. 
2478. Sporotrichum. From a-xd^/x,, and 3-§<|, hair, in allusion to the filamentous nature of the sporules A 
very destructive parasite in some seasons, and probably of general distribution, for it has been detected on a 
great variety of plants. To gardeners it is well known as a kind of mildew or blight, and is commonly taken 
for an insect. The leaves of the peach-trees, even when protected by glass, are often attacked by it, nor does 
the fruit itself always escape, in which case it frequently drops ofK The leaves are more or less distorted by 
it. As its production is probably the result of a peculiar state of the atmosphere, there is little chance of any 
means being discovered for its prevention.
