and Miscellaneous Particulars. 
2494. Sporidermium. From a-cro^o;, a sporule, and dii^f^oc, a skin, or coat. A plant of a very simple 
structure, composed entirely of linear-oblong or club-shaped semi-opake bodies, closely arranged side 
by side, exactly of the same height, and transversely divided by three or four dissepiments. When 
viewed with the naked eye, it resembles an intensely black thin crust, creeping over the surface of 
Thelephora. Specimens from Captain Carmichael, as well as those found by Dr. Greville, occurred on Thele- 
^^2^5^^^maspora. From vyi/J-et,, a thread, and <r^6^oe,, a sporule. The species resemble distorted threads filled 
with minute sporules. . , r. c^■ ■ 
2496. Cylindrosporium. In allusion to the cylindrical form of the sporules. Foimd on both surfaces ot living 
cabbage leaves (Brassica oleracea). Frequent in May and June. A very extraordinary plant, forming minute 
speck..like heaps of an oblong shape, but otherwise very irregular, and projecting into little angles and pro- 
cesses. They are disposed in a concentric manner, are pure white, and change in decay to a dirty yellow. 
Sporules naked, very numerous, cylindrical, truncate at each extremity, pellucid. 
2497. Uredo. An old Latin name, from uro, to burn or scorch, applied to those occasional discoloration s of 
the surfaces of plants which were attriibuted to blasts or injuries of the atmosphere or heavenly bodies, and are
