History, Use, Propagation, Culture, 
2405. Rkizoctonia. Subterraneous fungi, reposing upon the roots of living plants, which they destroy. The 
species appear in the summer or autumn, and are very destructive. They have received their name from their 
habits ; §<C«, a root, and xruvu), to destroy. They are very nearly related to the subterraneous Sclerotia. 
R. crocorum grows parasitically on the roots of the cultivated Saffron, Crocus sativus, in France, and is so 
pernicious as to have acquired the name of la mart du safran. It is very destructive, soon causing the bulb to 
perish, and spreading with great rapidity over a whole field of that valuable crop, if not speedily stopped by a 
trench fifteen to eighteen inches deep, to cut off the communication between the infected and the sound 
plants. The smallest quantity of earth from an infected field is said to be capable of communicating this 
plague, even if the ground were not planted with saffron till twenty years afterwards. " Hitherto this de. 
structive parasite has not been heard of but in France. The plants are of an irregular knobbed figure, from 
half an inch to an inch long, of a light reddish brown, scarcely bursting ; granular and paler within. Long 
branching capillary roots are sent out in all directions, propagating the plants very extensively and readily by 
offsets which attach themselves to the saffron, and multiplying in the substance of the bulbs soon destroy 
them." {Smith.) 
2446. Periola. From about, and loXos, hairiness, in allusion to the appearance the species exhibit when 
growing upon the roots of plants, or decaying fungi.
