Página 22 - ... sought out, or indeed caught hold of, and compelled into its service. It surrounds them, as a spider its prey, with a fibrous net of narrow meshes, which is gradually converted into an impenetrable covering ; but, whilst the spider sucks its prey and leaves it lying dead, the fungus incites the algae found in its net to more rapid activity — nay, to more vigorous increase.
Página 22 - As the result of my researches all these growths [Lichens] are not simple plants, not individuals in the ordinary sense of the word ; they are rather colonies, which consist of hundreds and thousands of individuals, of which, however, one alone plays the master, whilst the rest, in perpetual captivity, prepare the nutriment for themselves and their master.
Página 26 - Palmella-jelly," or a " Mesotaenium-jelly" (both aerial, that is, not under water), would seem in themselves to be possibly just as likely to afford the requisite pabulum for the germinating and growing Collema-spore. If this conjecture should be borne out, which I would indeed put with all diffidence, what would be the result of Reess's experiments, or rather, what proven thereby ? Such a combination {if capable) with a Palmella or a Mesotrenium would not be " Collema," because it would not have...
Página 79 - ... so characteristic of the class. Looking upon fungi from this chromatological point of view, they bear something like the same relation to lichens that the petals of a leafless parasitic plant would bear to the foliage of one of normal character — that is to say, they are, as it were, the coloured organs of reproduction of parasitic plants of a type closely approaching that of lichens, which, of course, is in very close, if not in absolute agreement with the conclusions drawn by botanists from...
Página 22 - Ascomycetes, a parasite which is accustomed to live upon others' work ; its slaves are green algse, which it has sought out, or indeed caught hold of, and compelled into its service. It surrounds them, as a spider its prey, with a fibrous net of narrow meshes, which is gradually converted into an impenetrable...
Página 75 - ... light was by no means so bright as in those parts of the wood where the spawn had penetrated more deeply, and where it was so intense that the roughest treatment scarcely seemed to check it. If any attempt was made to rub off the luminous matter it only shone the more brightly, and when wrapped up in five folds of paper the light penetrated through all the folds on either side as brightly as if the specimen was exposed ; when, again, the specimens were placed in the pocket, the pocket when opened...
Página 183 - Then, without ulteriorly undergoing any appreciable modification, the fertile cell, or oocyst, becomes enveloped in a lacework of filaments of mycelium which proceed from that which bears it, and this tissue forms the rudiments of the cap. The reality of some kind of fecundation in this circumstance, and the mode of the phenomenon, if there is one, are at present equally uncertain. If M.
Página 81 - Gills arcuato-decurrent, 8-9, very distant, rather thick, their margin and even the surface granulated. Allied to A. tenerrimus, which has crystalline particles on the pileus, but the gills are free and ventricose. On bramble and nettle stalks. Batheaston, 1869. March. Spores 3 mk. WP Name — saccharon, sugar ; fero, to bear. From the sugar-like granules. B. &
Página 93 - ... experience I have had with this family seems to confirm it. Rivulets should be watched especially in early spring, and during the summer months. From the time when the weather first grows cool in the autumn, on until the cold weather has fairly set in, and the reign of ice and snow commences, is the period during which the Algae hunter should search carefully all wet, dripping rocks, for specimens. Amongst the stems of wet mosses — in dark, damp crevices, and little grottos beneath shelving...
Página 92 - Again, when these plants are fruiting they lose their bright green colour and become dingy, often yellowish, and very dirty looking — just such specimens as the tyro would pass by. The fine, bright green, handsome masses of these algae are rarely worth carrying home. After all, however, much must be left to chance ; the best way is to gather small quantities from numerous localities, keeping them separate until they can be examined. Adhering to the various larger plants, to floating matters, twigs,...
