SPHÆRIA ciliaris. Bull. pl. 468. fig. 1.
Not unfrequent in damp places on rotten sticks and other woody substances, clothing them in parts with black hairs which issue from the minute sphærulæ. We have not detected it in its white powdery-form, as represented in Bulliard's figure.
TAB. CCCXL.
UREDO Thlaspi.
Very common in the autumn and spring, on the Shepherd's Purse, or Thlaspi Bursa-pastoris, about London. It has also been sent me from the neighbourhood of Norwich by Miss Hancock, where it like wife occurs in tolerable plenty. It is composed as it were of the scarf skin, or cuticle of the plant, covering a fine white downy substance, which holds a very fine powder. The Botritis parasiticus of Persoon's Obs. myc. tab. 5. fig. 6. & a. b. which we shall figure hereafter, is also very common on the Shepherd's Purse.
