I have seen an undescribed Agaric of the subgenus Omplialiaon Sphagnum at Mr. Euckers, and I am inclined to think that itis to this the mycelium belongs, but I have no proof to give thatsuch is the case.

Bateman, Esq., M.A., P.H.S., F.E.S.There are many Orchids (such as the more tender Oncidid) thatcan scarcely be induced to grow at all in baskets or pots, butwhich have been found to thrive if placed on a small block or

In thefirst place, the block of wood is apt to decay; and when this takes . place the plant has of course to be shifted to another block, achange that can never be effected without a wholesale disturbanceof the roots. Then again, especially if the temperature be humid,a minute kind of Alga, belonging apparently to the genus Colo-thrix, soon makes its appearance, which is excessively injuriousto the aerial roots of tender Orchids, and which it is extremelydifficult, I might almost say impossible, to keep in check. Underthese circumstances, it occurred to me that nothing more wasneeded than to copy in hard-baked clay the sort of branch onwhich Orchids usually thrive, which copy would, at all events,have this advantage, that once seated upon it, they need neveragain be disturbed. I accordingly communicated my views toMessrs. Boone and Son
