the coats curl inwards. Base rugged, knotty, buried in the earth. Skin 
thick, coriaceous, strong, dirty yellow white, or brown, very uneven, but 
not rough. Powder brown dirt colour, not evidently intermixed with 
woolly fibres, but brittle. Batsch. More leathery than any I have seen, 
with a very large coriaceous root. Mr. Stackhouse. 
(Sunken Puff-ball. Mr. Purton identifies with this species Tuber soli - 
dum and radicatum of With. It will probably appear that the plant here 
described is not specifically distinct from L. verrucosum. E.) 
Lyc. ardosia^ceum. (Bull.) Stemless; nearly globular, flexible, pur¬ 
plish lead colour, red within, changing to brown. 
Bull . 192, the four lower figures to the right hand.—Batsch 166. 
Grows on the ground only. Exists long after the dispersion of the seeds, 
and rattles like parchment. Bulliard.

Bovista plumbea. Pers. E.) Common on sandy heaths in Norfolk. Mr. 
Woodward.

Lyc. gossyp'inum. (Bull.) Head pear-shaped, white, cottony, taper

Lyc. pisifor'me. Stemless, globular, rough: orifice perforated. 
Jacq. Misc. i. 7. 
The size of a pea; sessile, crowded, brownish, rough with minute warts 
opening at the top. Orifice smooth. Nearly allied to L. epidendron , but 
has only one coat, whereas that has two. Jacq. Bulliard, from inatten¬ 
tion to this circumstance, has placed it as a variety of L. epidendron. 
It is either tawny or smoke-coloured, but always rough and warty, 
whereas L. epidendron is smooth. 
(Pea-like Puff-ball. E.) 
Lyc. epiphyl'lum. Clustered, parasitical: orifice many-cleft, torn; 
dust tawny. 
(Soiverby 397. 1 . E.) 
Small, sessile, tawny, variable in figure. Relh. n. 983. Not L. epiphyllum 
of Lightfoot, which is Trichia turbinata. 
(Border white, granulated. Centre red orange, powdery. This powder is 
composed of ovate particles which are probably the seeds. 
(Orange Parasitic Puff-ball. L. epiphyllum. Linn. Relh. JEcidium 
Tussiliginis. Pers. Purt. Sowerby. Hook. E.) On the back of the 
leaves of Tussilago farfara, very common. Decaying wood, leaves, and 
mosses. On the leaves of T. petasites. Mr. Woodward. On those of 
Bartsia viscosa. Mr. Stackhouse. Aug. May. 
The spots on the leaves of Sorbus aucuparia consist of minute globules inter¬ 
mixed with wool-like fibres. Aug. 1798.)
