Página 1 - The work is of such interest to students of this group that we quote the following selections from the introduction since they contain so much of general information regarding these curious organisms. "Fries gave the name of Myxogastres in 1833, to the group of organisms described in this Monograph, placing it among the Gasteromycetous Fungi. In 1836 Wallroth substituted the term Myxomycetes (Schleimpilze) for the older name, and this came to be the generally accepted designation. Later investigations...

Página 17 - ... by himself. Lankester accepts the groups as defined by de Bary, and places them in his grade Gymnomyxa of Protozoa; he suggests their affinity with the Sporozoa. The ingestion of bacteria by the swarm-cells appears to strengthen the view that the group is more nearly associated with the lower forms of animal than of vegetable life, and the name of Mycetozoa appears to mark its true position in the borderland between the two kingdoms. For a more complete discussion of this subject I must refer...
Página 119 - Denna varietet heskrefs af ROSTAFINSKI 1875 säsom en egen art, C. laxa. Det har dock sedan visat sig, att dess slägtskap med C. nigra är sädan, ett en artätskillnad knappast blir möjlig att upprätthälla. LISTER har ocksä tydligt uttryckt detta i sin monografi pag.
Página 47 - ... stalks is one of our commonest and most easily recognized Physarums. The sporangia are always some shade of yellow. Lister has recognized two varieties, var. aurantium and var. incanum, based on colour characters, but he leads one to doubt the validity of these varieties by a subsequent statement that "the colour of the sporangia found on the same stump may differ from year to year".
Página 21 - Sporophores membranous,, branched ; spores white, borne singly on filiform stalks arising from the areolated sporophore.
Página 2 - Didyostelium on the ground of its not forming a true plasmodium, we have a clearly defined group of organisms separated from all others by the following combination of characters. A spore provided with a firm wall produces on germination an amoeboid swarm-cell which soon acquires a flagellum. The swarm-cells multiply by division and subsequently coalesce to form a plasmodium which exhibits a rhythmic streaming. The plasmodium gives rise to fruits which consist of supporting structures and spores...

Página 1 - Wallroth, but linked with them the Acrasiece of Van Tieghem, a small group inhabiting the excrement of animals ; in these the spores are said to produce swarm-cells, as in the Myxomycetes, which multiply by division but do no coalesce to form a plasmodium. At a certain period, when the fruits are about to be formed, they become attached in branching strings which concentrate to a point, where they are massed together in aggregations of more or less definite shape ; the swarm-cells, however, do not...
