MUCOR botritis.
BOTRITIS parasiticus. Persoon Observationes mycologicæ. tab. 5. fig. 6.
Very frequent on the Shepherd's Purse, Thlaspi Bursa-pastoris., as is the Uredo Thlaspi, tab. 340. This has longer stems than that, which are often not perceptible, and grows on the outside of the plant, without the cuticle for a covering. May this not be the same one less deeply seated in the plant?
TAB. CCCLX.
FARINARIA seminaria.
This little production, found on leaves of a Willow, not yet described I believe, was sent me by the Rev. J. Holm of Cambridge. It appears to agree with some other things in my collection which are not referable to any known genus. I therefore call it Farinaria, being chiefly composed of fine powder.
No. 1.
Forms a little white nest holding black compacted powder-like feeds, if I may so call them; some I found empty, with the impressions remaining where these feeds seemed to have been.
No. 2. FARINARIA aurantiaca.
Are somewhat ovate particles scattered on the leaf, of an orange-colour, more or less in bundles; some in a compacted mass, others forming a kind of nest mixed with a few cottony filaments towards the edges.
No. 3. FARINARIA rosea.
Rose coloured particles rather indistinct, and nestling with some hairs at the extremities more or less enclosing them.
