 L. Cienkowski. Bot. Zeit. 21 June, 18G1. Vol. xix. p. 168. 



Lieberkuhn (MiJller's Arcliir. 1856. p. 494) and Schenk 

 (Verh. der ph. med. Ges. in Wvirzburg, 1858) have described 

 certain organisms parasitic upon the gills of the larvae of Phry- 

 ganea, Aselhts aquaticus, and Gammarus pulex. These organ- 

 isms have been since examined by Prof Cienkowski, who consi- 

 ders them to be forms of a unicellular plant, to which, from the 

 amoeboid character of its oospores, and its parasitic habit, he has 

 given the name of Anwebidium parasiticum. Cienkowski found 

 the plant on Phryganea and Gammarus pulex, and also very 

 plentifully upon the larvae of gnats. It is tubular or sac-shaped, 

 unicellidar, and variable in form ; the largest plants were 0.5™°^ 

 long by 0.01™™ broad; the smallest 0.015™™ long. In the spring 

 they produce in their interior spindle or sac- shaped bodies which 

 escape tlirough the cell-wallof the mother plant, being sometimes 

 projected by the elastic contraction of that cell- wall. Pear-shaped 

 zoospores are afterwards formed, which when free exhibit amoe- 

 boid expansions aud contractions, but are distinguishable from 

 Amoeba diffluens, which they much resemble, by the absence of a 

 contractile cavity. These zoospores eventually become motion- 

 less, and at once produce spindle-shaped bodies (young Amoebidia) 

 in their interior, or they become transformed into resting spores 

 which, after a time, also produce young Amoebidia. The author 

 concludes that Amoebidium is a plant belonging to the lower 

 algae or fungi. He then proceeds to describe a very singular 

 growth as to which he was long in doubt whether it belonged to, 

 or was parasitic upon, the Amoebidium. He describes the stages 

 of development of this growth, which is attached to the sides of 

 the Amoebidium, and when perfect consists of a large obovate or 

 pear-shaped cell, crowned with moniliform rows of cells like the 

 head of an xlspergillus. He concludes that it is a fungus, but 

 of doubtful affinity, and calls it Basidiolum fimbriatum. 



CoEMANS. — Eugene, contra Bonorden. Bot. Zeit. 6 Sept. 1861. 



Bonorden, in the paper noticed above, had objected that the 

 plants No. 232 aud 233, in liabenhorst's third Century, had been 

 wrongly described by Coemans as the pycnidiferous and spermo- 

 goniferous forms of Dermatea Cerasi. Coemans here states that 

 the name given to No. 232 has been confirmed by Tulasne ; but 

 with regai-d to No. 233, he now considers it a spermogoniferous
