Jig. 1678., is of a beautiful clear orange- 

 colour within. It grows generally on the 

 stumps of fallen oaks. P. bfcolor Bnll., 

 t. 410. f. .3., and P. cae'sia Pers. S//ii., 

 p. 057., are found on fallen oak branclios ; 

 ? and P. acicularis Pers., syn. P. wgaricifor- 

 mis, and our 7%. 1079., grows in old hol- 

 low trees. Bulgaria Inquinans Fries, Pe- 

 ziza Inquinans Pers. Syn., p. 631., P. 

 polymorpha .SrtM'., t. 428., and our fg. 1080., is a curiously shaped fungus, 

 and of a pitch-black colour. It is not unconnnon on old stumps and pollard 

 oak trees ; and is very tough and elastic. B. sarcoides Fries, dind our 7?". 1081. 

 is also found on old stumps. Cenangium yuercinuni 

 Fries, syn. Hysteriimi lyuercinum Pcrs. Syn., p. 110., 

 and our_/?fif.ie82., is extremely com- 

 mon on the small dead branches 

 which remain attached to the tree. 

 ^S When young, it bears a close re- 

 ^B semblance to a worm burrowing 



beneath the smooth bark. (E?ig. 16S4 



F/., V. p. 212.) Stictis radiata Pers. Syn., p. 074., and our /%. 1683., is 

 found occasionally on the bark. Tremella mesenterica Petz, and oiir^^. 1084., 

 of a bright orange colour; and T. intumescens Smith Eng. Bot., t. 1870., 

 and oxwfig. 1085. ; are found on trunks and branches. 16S5 

 The latter is " in perfection in very wet weather only, 

 when it forms numerous soft and pulpy clusters, twisted 

 and twined like the intestines of some animal ; of a 

 darkish dull brown, but with a shining surface, obscurely 

 dotted." {Smith.) Exidia auricula Judoe Fries, Peziza 

 auricula Lin., and our^cp. 1G80., grows on living trees. 

 The " upper surface is corrugated ; and the plants branching from the middle 

 part, where they are strongest, are somewhat convoluted, so as to give the 

 idea of a human ear. When the plant grows on a perpendicular stump or 

 tree, it turns upwards." (Smith.) This fungus is found on the ji^jjfi 



oak, the elder, and many other trees. Exidia glandulosa Fries, 

 syn. Tremella flaccida Eng. Bot., t. 2452., and our ^g. 1087., 

 vulgarly called witches' butter, is a curious drooping fungus, 

 found on the bark. Sclerotium (/uercigenum Berk, grows on ■ 

 felled oaks ; Sphas^ria botryosa Fries, on hard oak wood ; S. 

 mutabilis Pers., on indurated stumps tossing about in woods ; S. aspera Fries, 

 on oak branches ; S. uda Pers., on oak wood in moist places ; S. coroniita 

 Hoff., S. taleola Fries, and S. (/uercina Pers., on living branches ; and 5S. 

 leiphae^mia Fries, on dead branches. S. nucula Fnr.?, and 

 Hysterium Carmichaeli«H;(7w Berk., syn. H. varium Grev., 

 are found on oak bark. H. rugosiun Fries is produced on 

 the smooth branches of the oak, and a variety occurs on 

 the beech ; H. pulicare, on the rotten wood of the oak ; 

 and Helminthosporium subulatum Xces on oak branches, 

 Oidiumaureum Link, of a beautiful golden orange colour, 

 was found in the hollow of theFairlop Oak; and Psilonia 

 gilva Fries, more frequent on the stems of the larger herbaceous plants, 

 growing on the flat surface of a felled oak. 



Besides these, which all grow on the trunk and branches of the trees, the 

 following are found on the roots: — -igaricus aurantiaco-ferrugineus With.; 

 and Polyporus frondosus Fries, Schccjf., t. 127., which is reported excellent for 

 food, sometimes attains the weight of 30 lb. ; and, in Hungary, has been found 

 2 ft. high, and 3 ft. broad. When gatheretl, it smells like mice. Scleroderma 

 citrinum Pers., Bo/t. Fun., t. 1 16., and our^g. 1088., also grows on the roots.
