das auf kränkelnden Tabaksblättern auftretende Amblyosporlum echinii- 

 latum Oudem. bemerkenswerth. Unter den Dernatieen hebe ich Hetero- 

 sporium Chamaeropis Oud. auf Chamaerops excelsa hervor. Von 

 Stilbeen werden drei neue Arten der Gattung Tilacltlidium beschrieben, 

 die sämmtlich von Herrn C. J. Koning auf Waldboden oder den Bruch- 

 stücken der dort liegenden alten Eichenblätter gesammelt sind.

La femelle brune, qui est inorte, est le siege d'une 

 dehiscence mecanique sous l'influence de la chaleur et de 

 rhumidite. 



Dans les annees tres seches comme celle-ci, les oeufs, les 

 embryons, les larves restent ä l'abri de l'enveloppe maternelle 

 jusqu'au mois de septembre, tandis que , dans les annees 

 ordinaires les femelles du Nematode de la Betterave sont vides 

 en juillet et en aoüt. Par les grandes secheresses, l'incubation 

 est suspendue, comme en hiver. Paul Vuillemin (Nancy).

The occurrence of this species of fungus is recorded from Kent. 



It is an addition to the British Fungus Flora. G. Massee (Kew).

Although it has for a long time been assumed that the 

 presence of certain species of fun^i growing on düng originated 

 Irom spores that had been swallowed along with food, no de- 

 finite proof of such an assumption was forthcoming. To settle 

 this point short portions of the intestine of a recently killed 

 rabbit vvere tied up before removal from the body. The tied- 

 up portions vvere then removed and placed in a sterilized vessel 

 and covered by a bell-jar, the düng being exposed by cutting 

 open the skin of the intestine. A the end of six days the düng 

 was covered with a profuse growth of Vilaira anomala Schrot., 

 Pilobolns cry stall in US Tode, Mucor miicedo L., Chaetocladiiim 

 Jonesii Pres., parasitic on the Miicor\ and Coprimis 

 niveus Pers. 



A second batch of rabbit düng yielded at the espiration 

 of a fortnight, all the species of fungi enumerated in the first 

 experiment, and in addition, Gymnoasciis Reessü Baran., 

 Hnmaria gramilata Sacc, Sporormla intermedia Wint., and 

 Sordaria decipiens Wint. A third experiment conducted with 

 sheep düng, obtained directly from the intestine as described 

 above, and only liberated from it when placed under a bell-jar, 

 ^Iso yielded several characteristic coprophilous fungi,
