My dear Sir

I have received your very obliging note & likewise your enclosure of to day—

I am delighted that you have found the edible fungus botanically curious— I shall be much interested in reading your paper—¹ I trust you corrected the language of such extracts, as you thought worth taking— I did not think any were so—

I write now to inform you that I have probably led you into one small error— I stated that the Fungus grows on the Fagus antarctica,² but I am almost certain that the F. betuloides is the common tree of Tierra del Fuego, & as this Fungus abounds every where it must grow on this latter species— it may (& I believe does) grow on the F. antarctica. You can correct this in proof, if you think it desirable—³

I saw my brother-in law—Hensleigh Wedgwood, your former schoolfellow & collegian,⁴ to day & he begged to be very kindly remembered to you.—

Believe me dear Sir | Your’s truly obliged | C. Darwin
