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; ρiζa, a root, and κτεivω, 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 mort 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 περi, about, and 10λoς, hairiness, in allusion to the appearance the species exhibit when growing upon the roots of plants, or decaying fungi. ORD. IX. TRIBE I.

Most of the productions arranged under this head are known by their the popular name of mildew. They are better characterized by the plants on which they grow, are than by the popular name of mildew. They are better characterized by the plants on which they grow, than by their peculiar differences, which, it is probable, depend very much upon the former circumstance. 2409. Phallus. Large terrestrial fungi, sometimes growing upon rotten wood, not clustered, appearing in the summer after thunderstorms, fetid, and highly poisonous. Their form is so similar to that of the φaλλoς of the Greeks, as not to be overlooked. 2410. Batarrea. So named by Persoon, in honor of Antonio Batarra, professor of botany in the Lyceum at Rimini, and author of a Historia Fungorum Agri Ariminensis, published at Faenza, in 1759, in quarto, with forty plates. A very curious plant found only in England, where, however, it is exceeding rare. The volva or wrapper is about the size of a hen's egg, originally of three slightly coriaceous layers, hollow internally, when a spongy stalk is formed which rises suddenly to its full height of about twelve inches. This stalk carries up on its summit full half the innermost layer of the vol externally with copious brown sporules intermixed with fibres. volva, which is white and smooth within, and covered 2411.
