Fig. 2. F. ramosissima.
THIS is not uncommon on plastered brick walls, and sometimes branches very irregularly, at others concentrically, often in very large patches. This is a piece of one which grew on a wall in a middle cellar at Mr. Forster's at Lambeth, and was above two feet in diameter.

THE fibrillæ of which this is composed are not much unlike the two last, though somewhat more tender when fresh, and brittle when dry. This is figured by Dillenius 1. 12; and Dr. Withering, in the 3d ed. of his Arrangement, vol. 4. page 146, traces it from a yellowish or reddish colour to brown, and at length to black, observing that it resembles the skin of a mouse: he should have added 'when compressed.' He thinks it a variety of figure 6 following. If so, it is a Boletus.
Fig. 4. Clavaria filiformis. Bull. 448. 1.
THIS is not uncommon among dead leaves when thickly strewed on the ground. It is composed of fibrillæ not unlike Byssus barbata, E. Botany, tab. 701; but in drying shrivels up almost to nothing.
Fig. 5. Boletus terrestris.
FOUND on the ground in woods, often spreading an inch or two in diameter, without any sign of being any thing but a compound of fine and small fibres interwoven and lying flat on the ground. However, we have met with it forming pores so as to constitute it a Boletus.
Fig. 6. Boletus hybridus. See tab. 289 of this work.
THIS beautifully white, most delicately tender and fine fibrous cottony substance is often copious in close cellars, along with what is represented at. fig. 3. (this latter has sometimes been found on rotten wood under the earth), and is composed at first of fibres, not unlike the longer stems of Mucor mucedo, tab. 378. fig. 6. nearly as figured by Dill. tab. 1. fig. 9. and is said to
