The sporophores of Lentinus siinilis are always found growing 

 from irregulär masses of wood, which occur loose among the debris 

 in basins formed by deca}'' at the top of Hevea stumps. On micros- 

 copic examination the elements of the wood in these masses are 

 seen to be completely filled with mycelium. Their formation is ex- 

 plained as foUows. The mycelium attacks and destroys the dead 

 wood, but several portions are left more or less unchanged. When 

 the decayed tissue weathers awa)'', these portions are left embedded 

 in the soil, or are washed out by the rain and lie free on the sur- 

 face. The}'- subsequently give rise to the Lentinus sporophores, the 

 mycelium in them being apparently storage mycelium. The name 

 pseudo-sclerotia is therefore suggested. In this species sporophores 

 are only produced by the pseudo-sclerotia. 



In Lenthnis infundihuliforniis a somewhat similar pseudo-sclero- 

 tium occurs, but the formation of the masses is not so constant as 

 in the case of L. similis. 



Details are given of the action of the two fungi on the wood, 

 and the characters and reactions of the mycelium.

 drome entolomien. (Assoc. fr. Av. Sc. Congres du Havre. 

 1914. p. 884—886. Paris 1915.) 



L'auteur enumere plus de cent cas d'empoisonnement par VEn- 

 toloma lividum. Deux cas aboutirent ä la mort. La partie charnue 

 du chapeau est plus toxique que les lames et le pied. L'ebullition 

 du suc ne detruit pas le poison, dont la nature est indeterminee. 

 Les accidents debutent brusquement apres une ou deux heures 

 d'incubation, par des vomissements, de la diarrhee, divers troubles 

 gastro-intestinaux. Plus tard surviennent des troubles pupillaires, 

 des syncopes, une soif atroce. L'intelligence est rarement atteinte.
