On living trees, especially elder. Early autumn and winter ; not un- 

 common. — Plant 1 — 3 inches or more broad. Upper substance corru- 

 gated, the plaits branching from the middle part where they are strongest 

 and somewhat convoluted, so as to give an idea of a human ear. When 

 the plant grows on a perpendicular stump or tree, it turns upwards." 

 Sm. I. c. The last circumstance shows the essential difference between 

 the present plant and Phlehia 7nesenterica, which otherwise would 

 seem to claim a place in this genus, for the absence of papillae could 

 scarcely be supposed of sufficient importance to exclude it. The ten- 

 dency in the lower Pileati is always to turn the hymenium away from 

 the light, thus approaching a step nearer to the normal form. This, or 

 some very nearly allied species, occurs also in tropical climates. 



2. E. recisa, Ditm. (reddish-broum Exidia) ; very soft trun- 

 cate plane or somewliat repand reddish-brown punctato-sca- 

 brous beneath, stem very short excentric oblique. Fr. Syst,

On dry dead branches of Sallows, often while yet attached to the 

 tree. Autumn and winter; common. — About 1 inch broad. Sporidia 

 oblong, obtuse, curved, exactly resembling those of T. albida. 



3. P. glandulosa, Bull. {Witches Butter); effused more or 

 less plane thick undulated, at length black, hymenium beset 

 with conical spicules, beneath cinereous subtomentose. Fr,

On trunks and branches of trees, especially ash. Autumn and win- 

 ter ; frequent.— Varying in colour from whitish to brown and deep 

 cinereous, at length black. Generally somewhat^ turbinate, slightly 

 plicate below, much wrinkled above ; sometimes thin. Substance ten- 

 der within, firmer towards the hymenium, composed of gelatine inter- 

 laced with very slender branchedj?/awe;?^5, indistinctly moniliform under 

 a high magnifier, covered with oblong obtuse curved 5/;»o?7£/m between the 

 conical sp'icules, which are frequently surmounted with a glandular white 

 globule. Beneath, rough like crape, with minute parallel^ papillae. 

 Brown specimens, which now and then occur, may be distinguished 

 from the foregoing species, by the more highly developed spicules. T. 

 faccida, Eng. Bot. is a very curious drooping variety.

 Receptacle gelatinous, surrounding an heterogenous compact 

 nucleus. Sporidia bursting forth. — Named from i^rj/^a, gelatine^ 

 and s/Asw, to involve.
