History, Use, Propagation, Culture, 
2435. Actinothyrium. So called from ccxnv, a ray, and ^v^oca, to enclose, in allusion to the radiated 
integument of the sporidia. The only known species is innate, growing upon plants, orbicular, almost black, 
and appearing in the early part of the year. 
2436. Leptostroma. From Xt^TTo;, thin or delicate, and s-^u/mx,, a layer, in allusion to the disk, which, \7hen 
the perithecium separates, becomes naked and very thin. 
2437. Xyloma. From luXov, wood, and Xco/mx,, a margin. The species are innate coated tubercles, of a hard 
vesicular substance, but which does not produce fructification. One of the most common kinds, X. acerinura, 
has a ragged border. 
2438. Lasiobotrys. From Xoctrio?, wool, and (ior^v;, a bunch. This plant originates beneath the epidermis of 
the leaf, during its green and living state. When mature, it is of a very black color, and regular circular 
form, from one to two lines in breadth, very slightly convex, the surface uniformly granulated, and the 
whole generally situated on a paler or colorless portion of the leaf On the bursting or laceration of the 
epidermis of the leaf, which takes place in the centre, our plant is found to consist of a multitude of 
distinct perithecia of a roundish form, closely arranged side by side, destitute of orifice, and the summits of 
which produce a granulated appearance to the naked eye or a small magnifier. These perithecia are fixed 
to the leaf by a number of short filaments radiating from their base, and are not to be detached without some
