Pl°- e.—Catocera viscom. These cells are filled with a protoplasm, to which the plant owes its orange colour. When they have attained their normal dimensions, they elongate at the summit into two, three, or four distinct, thick, obtuse tubes, into which the protoplasm gradually passes. The development of these tubes is unequal and not simultaneous, so that one will often attain its full dimensions, equal, per- haps, to three or four times the dia- meter of the generative cell, whilst the others are only just appearing. By degrees, as each tube attains its full size, it is attenuated into a fine point, the extremity of which swells into a spheroidal cell, which ulti- mately becomes a spore. Sometimes these tubes, or spicules, send out one or two lateral branches, each terminated by a spore. These spores (about '006 to -008 mm. diameter) are smooth, and deposit themselves, like a fine white dust, on the surface of the Tremella and on its matrix. M. Leveille f was of opinion that.
