It seems remari able to tho se unaequainted With his oWn occultreaSons, Wherefore Saccardo haS removed this genus hom iis manifest assinitius in Thelephorei and placed it With Clanaria, With Whicli, on tho othor hanii, it has no relations hip, excepi that ofexternat form. Obviolasty the laterat hymenium, coriaceous Substance, and dry persistent sorvi, brings it into proximity With Thelephora, hom Some SpecieS of Whicli Lachnocladium is scarcelyseparated.

Berheley, in describing the present species, says that the verticallobes bearing tho hymenium are united at the tips, und on this account the species has been removed to the genus Colus, by Fischer ;but in reality the segments are not organicatly united at the tips, but during the young Stage are closely preSSed together, and having boon dried in this condition appear to be united ; hoWever, Whun the mucit age is moisten ed tho tips aro found to be qui te fr00,

The rum aining species included by Saccardo in this foetion maybo thus disposed os. Trametes meaeicana, B. y C., and Pramete3zebrina, Fr., have the substance too darii for this group. Tramutes Cookei, Sacc. Syll. 6202, is evidently an error, as itis not a triae Trametes, and haS already app0ared under Polysticius, in iis proper place, as Polysticius acuta, No. 5702. The t o specieS, Trametes paleaeea, Fries, and Trametes immutata, Ber ., Would go into recedente8. The re maining T. vittata, Leu.; P. tegularis, Leu.; P. aphans-poda, Reicli., and probably P. bicolor, Berli., are corineeOUS. Trametes limitata, Ber ., Saco.
