1681 fig. 1678., is of a beautiful clear orange- 
colour within, It grows generally on the 
iy stumps of fallen oaks. P. bicolor Bull., 
ly t. 410. f. 3., and P. cx'sia Pers. Syn., 
p- 657., are found on fallen oak branches ; 
WF and P. aciculiris Pers., syn. P. agaricifor- 
a mis,:and our fig. 1679., grows in old hol- 
low trees. Bulgaria inquinans Fries, Pe- 
ziza inquinans Pers. Syn., p. 631., P. ——= 
polymérpha Sow., t. 428., and our jig. 1680., is a curiously shaped fungus, 
and of a pitch-black colour. It is not uncommon on old stumps and pollard 
oak trees ; and is very tough andelastic. B. sarcdides Fries, and our fig. 1681., 
is also found on old stumps. Cenangium quércinum 
Fries, syn. Hystérium quércinum Pers. Syn., p. 110., 
and our fig.1682., is extremely com- 
mon on the small dead branches 
. which remain attached to the tree. 
<= When young, it bears a close re- 
= semblance to a worm burrowing %* eS 
- beneath the smooth bark. (ng. 1634 
Fi., v. p. 212.) — Stictis radiata Pers. Syn., p. 674., and our fig. 1683., is 
found occasionally on the bark. Tremélla mesentérica Retz, and our fig. 1684., 
of a bright orange colour; and T. intuméscens Smith Eng. Bot., t. 1870., 
and our fig. 1685. ; are found on trunks and branches. 
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 Jide Fries, Peziza 
auricula Lin., and our fig. 1686., 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 1686 
oak, the elder, and many other trees. Exidia glandulosa Fries, 
syn. Tremélla flaccida Eng. Bot., t. 2452., and our fig. 1687., 
vulgarly called witches’ butter, is a curious drooping fungus, 
found on the bark. Sclerdtium quercigenum Berk. grows on 4 
felled oaks; Sphze‘ria botrydsa Fries, on hard oak wood; S. 
mutabilis Pers., on indurated stumps tossing about in woods ; S, aspera Fries, 
on oak branches; S. dda Pers., on oak wood in moist places; S. coronata 
Hoff, 8. taléola Fries, and S. quéreina Pers., on living branches; and 8. 
leiphze‘mia Fries, on dead branches. S. ntcula Fries, and 
Hystérium Carmichaelidnum Berk., syn. H. varium Grev., 
sare found on oak bark. H. rugdsum Fries is produced on 
the smooth branches of the oak, and a variety occurs on 
the beech; H. pulicire, on the rotten wood of the oak; 
and Helminthosporium subulatum Nees on oak branches. 
Ofidium atreum Link, of a beautiful golden orange colour, 
was found in the hollow of the Fairlop 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: — Agaricus aurant{iaco-ferrugineus With.; 
and Polyporus frondésus Fries, Scheff:, t. 127., which is reported excellent for 
food, sometimes attains the weight of 30 |b. ; and, in Hungary, has been found 
2 ft. high, and 3 ft. broad. When gathered, it smells like mice. Sclerodérma 
eitrinum Pers., Bolt, Fun., t.116., and our fig. 1688., also grows on the roots.
