polymorpha 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 pollardoak trees ; and is very tough and elastic. B. sarcoides Fries, and om Jig. 1681.,is also found on old stumps. Cenangium juerciniunFries, syn. Hysterium qudrcinum Pers. Syn., p. 110.,and ourjfg.1682., is extremely com--—mon on the small dead brancheswhich remain attached to the tree.

When young, it bears a close re-jUg semblance to a worm burrowing

beneath the smooth bark. (Eng. 1634

FI., v. p. 212.) Stictis radiata Pers. Syn., p. 674., and our Jig. 1683., isfound occasionally on the bark. Tremella mesenterica Retz, and our Jig. 1684.,of a bright orange colour; and T. intumescens Smith Eng. Bot., t. 1870.,and our Jig. 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, twistedand twined like the intestines of some animal; of adarkish dull brown, but with a shining surface, obscurelydotted.” (Smith.) Exidia auricula Judae Fries, Pezizaauricula Lin., and our Jig. 1686., grows on living trees.

The “upper surface is corrugated; and the plants branching from the middlepart, where they are strongest, are somewhat convoluted, so as to give theidea of a human ear. When the plant grows on a perpendicular stump ortree, it turns upwards.” (Smith.) This fungus is found on the 1086

oak, the elder, and many other trees. Exidia glandulosa Fries,syn. Tremella flaccida Eng. Bot., t. 2452., and our Jig. 1687.,vulgarly called witches’ butter, is a curious drooping fungus,found on the bark. Sclerotium juercigenum Berk, grows on <felled oaks; Sphae'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. coronataHoff., S. taleola Fries, and S. ^uercina Pers., on living branches; and S.leiphae'mia Fries, on dead branches. S. nucula Fries, andHysterium CarmichaelzaWm Berk., syn. H. varium Grev.,are found on oak bark. H. rugosum Fries is produced onthe smooth branches of the oak, and a variety occurs onthe beech; H. pulicare, on the rotten wood of the oak;and Helminthosporium subulatum Fees on oak branches.

Oidium aureum Link, of a beautiful golden orange colour,was found in the hollow of the Fairlop Oak; and Psildniagilva Fries, more frequent on the stems of the largergrowing on the flat surface of a felled oak.

Besides these, which all grow on the trunk and branches of the trees, thefollowing are found on the roots: — Hgaricus aurantiaco-ferrugineus With.;and Polyporus frondosus Fries, Sclueff., t. 127., which is reported excellent forfood, sometimes attains the weight of 30 lb.; and, in Hungary , has been found2,ft high, and 3 ft. broad. When gathered, it smells like mice. Sclerodermawtrinum Pers., Bolt. Fun., t. 116., and our j%. 1688., also grows on the roots.Amongst the fungi which grow on the ground under the shade of the oak
