The lovely but untouchably glutinous Agaricus mucidus, generally so frequent on the High Beach beeches, was this year nowhere to be seen. The Falstaffean Boletus edulis was common, as well as B. chrysenteron and B. subtomentosus. The milk mushrooms, Lactarii, were abundant; the poisonous, livid, Lactarius lividus, was everywhere; L. quietus, so mild that none need fear his quietus from consuming it, was also very common ; "odour oily—like bugs," writes Mr. Berkeley ; other authorities say the odour is "mealy, like recent farina." Perhaps the "mealy-bug" was in view, but this is not stated ! Boletus scaber, grey, ugly, sticky, and vile to the sight, albeit an edible species, was to be noted almost everywhere ; and B. luridus was frequent, rapidly changing to blue when cut or broken—a pretty toy for the ladies, quickly poisonous to some people, but a delicious viand to the indurated hippogastrous fungo- phagist. We must not, however, weary our readers by attempting a catalogue of all the species met with ; a list of the forest Hymenomycetes as far as at present ascertained, is given in this part of the ' Transactions '; most of them are common in the woods every autumn, and many were recorded in the account of last year's fungological ramble [Proceedings, i. xlviii.] Many of the visitors were struck with the beauty and luxuriance of the golden Peziza aurantia, growing in large patches in and about the road ruts and newly-cut water-courses, particularly in Fairmead Bottom and near Golding's Hill. But one remarkable fungus certainly demands a special paragraph in our records, viz., Coprinus aratus. This is probably a rarity, and has not been seen by the writer for the last twenty years. Mr. Berkeley first found it "in a hollow tree." It was one of the first Fungi to attract our notice when commencing the observation of the Cryptogamia, growing twenty years ago at the bottom of a dung-heap in Nottinghamshire. Coprinus aratus is one of the larger, deliquescent, fugitive species; it grows to be six inches high, stem tapering upwards, very hollow and fragile, a top from three to five inches across, tender, and breaking to pieces with a touch. It lives less than a day, and in decay it curls up into beautiful volutes, and distils itself away into drops of black and tumid ink. Dr. Wharton had the pleasure of discovering the specimen in Monk Wood, which was, alas! but a ruin, suffering from a dread and fatal mycoclysm; however, the remnants were brought carefully home for the microscopic examination. of the cystidia. As these organs (con- cerning the exact nature of which much difference of opinion prevails, although Dr. Cooke states that the evidence seems to be in favour of the
