Encloses duplicate of letter he sent Smith in March [1807] [extant], and packet of plants; wishes to know Smith's opinion of this and the packet he sent October 1806. Asks if his new genus 'Gwillimia' has been accepted.

Discusses 'Dianthus caryophyllus' and proposes two additions to Smith's description of the genus, being 'caryophyllus' and 'hortensia', with three small sketches in pen illustrating his argument. Justifies his course of study.

Received Smith's letter of 20 October [1807] today; has not yet received [Johann Baptist von] Albertini's "Conspectus Fungorum" from Germany; hopes Albertini will send a copy as he assisted in collecting materials for it. Encloses specimens of some of the fungi he sent for the work, and hopes to also send the copper plates.

Lists fungi he has found since his last letter to Smith: 'Boletus fimbriatus', 'B. mucidus', 'B. cinnabarinus', 'Thelephora hirsuta', 'T. calcea', 'T. polygonia', 'Tremella encephala', 'Agaricus amesthystinus', 'A. procenus', 'A. violaceus', 'A. fratensis', 'A. luridus', 'A. coccineus', 'A. conicus', 'A. poittacinus', 'A. seracius', 'A. punus', 'A. copinusdomesticus', 'A. frauncilus', 'A. caudicinus', 'A. semiglobatus', 'A. fascicularis', 'A. subdulcis', 'A. anuginosa', 'A. campestris', 'A. collinitus', 'Capninus extinclonius', 'C. candicans', 'Gymnopus latus', 'G. alboviolaceus', 'G. lactillacris', 'Boletus subtomentosus', 'B. fuscus', 'B. deofunctor', 'B. vitneus', 'B. hepaticus', 'Helvella cinerea' (very rare), 'Lycoperdon pratense', 'L. umbrinum', 'L. bovista', 'Filago rusa', 'Spumaria mucilago', 'Stemonitis ovala', 'S. fascicularis', 'Accidium tussilaginus', 'Amanila spadicea', 'Hydnum ochnaceum', 'Clavaria protensis', 'C. cornea', 'C. elurnia', 'C. mirani', 'Peziza sancoides', 'P. anomala', 'Sphaeria hypoxylon', S. digitata', 'S. fusca', 'S. poronia', 'S. deusta', 'S. doliolum', and 'S. disciformis'. Found all of the above with [Henry] Steinhauer at Kirklees Hall, the seat of Sir George Armitage.

Has sent Smith specimen of 'Anemone vernalis'. Will send a fern with the copper plates, variety of 'Cyathea fragilis' from Castleton, which he has been unable to find in "Flora Britannica", which he hopes will be completed.

Discusses his essay, "De Pisolitho", which he sent for Smith's opinion, and quoting of Scopoli's 'Lycoperdon arrizon' as a synonym for 'Pisolithus arenarius'; proposes naming it 'P. scopolii' [coloured drawing extant]. Apologises for delay in sending promised plates of [Johann Baptist von] Albertini's "Conspectus Fungorum", which his friend Mr Steinhaur will now do. Lists recent fungi he has found: 'Xyloma acerinum', 'Agaricus lactifluus var. deliciosus', 'Clavaria ericelorum', 'C. gyrans', 'Sphaeria militaris', 'Hydnum repandum', 'Peziza papillata', and 'Tremella auriformis'; always uses [Christiaan Hendrik] Persoon's names, despite some of them not seemingly appropriate for the plants they are meant to denominate.

He has minutely examined the fern mentioned in his last letter and concludes it is either new or a new variety, possibly of 'Aspidium spinulosum'. Found a variety of 'Blechnum boreale'; observations. Bolton's discovery of 'Hyminophyllum pyxidifenum'.
