$portions of a foot affected with the “ Black Fungus,”—magnified to show its development from the germinating sporidia a, a, a, to the formation and bursting of the spore f. a, a, a, a, germinating sporidia ; b, b, b, commencement of spore-cells containing nucleus j c, nucleus and contents of spore-cell further advanced \ d, apparent quadruphcation of contents of spore-cell, with further sub-duplication of their interior, e, spore and sporidia formed ; f spore bursting; g, sporidia more highly magnified, to show shape and nucleus \ h, spore embraced by a conden- sation of small filaments—very common if not constant. In the figures under A, a filament is represented which is composed of cells with a nucleus at one end of each, and under B, is represented the ‘ felt-like ’ form of the layer of red fungus as it grows in the bottle ; a, filamentous layer; b, layer of spores ; c, filamentous layer below. 458. other Forms of Fungi.—Low forms of cryptogamia have also been found in the lung by Professor Bennett, and have been noticed in the stools by him and other observers. Meissner describes a fungus which he found amongst the cells of the nails of an octogenarian. The nail was rendered transparent by caustic soda. It was permeated in every part by the fungus. Fungi have been found in glandered lungs; on the pleura (Roger and Gardner); in the expectoration of phthisis (Remak); and in the kidney by Tonge and Powell, pi. LXXXV, figs. 9, io. There is a group—Leptomitus, whose “ characteristic feature is an enlarged ovoid cell, mostly terminal with a little projecting joint at the apex, and containing more or less nuclei—the whole resembling a club very much” (Fox). The following varieties have been found, L. urophilus in the urine ; L. Hannoveri in the oesophagus and stomach ; in typhus by Robin; in bronchitis by Fuchs. Z. uteri, called by Dr. Wilkinson, Lancet, 1849, p. 449, Lorum uteri, in consequence of the supposed breaking up of the terminal cell into several threads, so as to resemble a rash, and another form has been detected by Gubler in the epidermis in a case of gun-shot wound of the arm. Dr. Tilbury Fox has clearly shown that all the forms of Leptomitus are forms of oi'dium. The terminal and aerial filaments bearing the oidial, and the basal the leptomitus character, see pi. LXXXIV. The Lorum uteri is nothing more nor less than a free branching or buddingout from the large ovoid cell of the ordinary Leptomitus. 459. The identification of many of the fungi above referred to is a most difficult matter. Indeed, unless the organism can be studied at different periods of its development, it is almost impossible to assign to it its proper name. Moreover, the drawings given in different works when original differ so much from one another that not only students but teachers and authorities are often much perplexed. Moreover all these fungi at an early period of development are but minute particles 2 k$
