Fig. 2. F. ramosissima. 

 THIS is not uncommon on plaftered brick walls, 

 and fometimes 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. Forfter's at Lambeth, and was above two feet in 



diameter.

THE fibrillas of which this is compofed are not 

 much unlike the two laft, though fomewhat more ten- 

 der when frefli, and brittle when dry. This is figured 

 by Dillenius i. 12 ; and Dr. Withering, in the 3d ed. of 

 his Arrangement, vol. 4. page 146, traces it fromayel- 

 lowilli or reddifli colour to brown, and at length to 

 black, obferving that it refembles the fkin of a moufe : 

 he lliould have added ' when compreffed.' He thinks it 

 a variety of figure 6 following. If fo, it is a Boletus. 



Fig. 4. Clavaria filiformis. Bull. 448. i. 



THIS is not uncommon among dead leaves when 

 thickly ftrewed on the ground. It is compofed of 

 fibrillce not unlike Byjfus barbata^ E. Botany, tab. 701 ; 

 but in drying fhrivels up almoil: to nothing. 



Fig. 5. Boletus terrestris. 



FOUND on the ground in woods, often fpreading 

 an inch or two in diameter, without any fign of being 

 any thing but a compound of fine and fmall fibres in- 

 terwoven and lying flat on the ground. However, we 

 have met with it forming pores fo as to conftitute it a 

 Boletus. 



Fig. 6. Boletus hybridus. See tab. 289 of this work. 

 THIS beautifully white, moft delicately tender and 

 fine fibrous cottony fubfiance is often copious in clofe 

 cellars, along with what is reprefented 2i\. Jig. 3. (this 

 latter has fometimes been found on rotten wood under 

 the earth), and is compofed at firft of fibres, not un- 

 like the longer ftems of Mucor mucedo^ tab. 378.7?^. 6. 

 nearly as figured by Dill. tab. i. fg. 9. and is faid to
