THEIR STUDY IN BRITAIN. 7 at Kew, showing that the friends had shared their treasures. Berkeley often visited Broome in his home near Bath, in a district where the moist wooded valleys formed a prolific hunting- ground for all kinds of fungi. Broome was a cultivated man of wide interests and somewhat austere habits. He had a retiring disposition, but proved a charming companion to his intimate friends. The next advance in our knowledge of Mycetozoa in Britain is due to one who has only lately been taken from us. Dr. M. C. Cooke. To many of us, Dr. Cooke was for a number of years a familiar figure on the occasion of our Club's annual Fungus Forays, when he gave his valuable services as referee, and when, in the evenings, he would sum up the results of the day's work, or give some pithy address on the wider aspects of fungus life. We well remember his short lean figure, his quiet energy, and the quaint humour with which he would enliven the most technical discourse. His Handbook of British Fungi, published in two volumes in 1871, was, as he tells us, a revision of Berkeley's work. By adding descriptions of new species published since 1836, as well as of those continental species recently found in Britain, by giving concise keys to many genera and supplying excellent woodcuts illustrating every genus, Cooke produced an extremely valuable and convenient book of reference. As regards Mycetozoa, many species were added to those recorded in English Flora, but no critical attention was paid to the group. Cooke himself was well aware that the, subject deserved better treat- ment. When, in 1875, Dr. Joseph Rostafinski published under the supervision of his great master, De Bary, his magnificent Monograph of Mycetozoa (written, alas ! in the Polish language), Cooke had the energy to translate into English all the keys of genera and species and the descriptions of such species as were then known to be British. The value of this book was much enhanced by the plates, which consist of reproductions of nearly all Rostafinski's beautiful illustrations. In this modest- looking volume, entitled The Myxomycetes of Great Britain, English readers had for the first time a work dealing thoroughly with the microscopic structure of Mycetozoa, on the characters of which the true affinities of the species are found to depend. It is curious that, with all his respect for the work of De Bary
