70 SUMMARY OF CURRENT RESEARCHES RELATING TO 



S. tomentosa found on Euphorbia, as the latter occurs very frequently 

 in regions where the other is as yet unknown. 



Diseases of the Vanilla.* — G. Delacroix reviews Massee's work on 

 the parasitic fungus Calospora Va?iillce. He finds that the measure- 

 ments and descriptions given by Massee do not tally with those of the 

 fungus causing the Vanilla disease. He determines the fungus to be a 

 Vermicularia with its conidial form Colletotrichum Vanilla,. He gives 

 an account of the disease as it affects the trees, with descriptions of the 

 various fungi associated with the attack, and suggests the best means 

 of cure. 



Disease of Bananas.f — G. Delacroix calls attention to the black 

 discoloration so often seen on Banana fruits. It is caused by the growth 

 of a fungus Glozosporium Musarum Cooke and Mass., which form little 

 red conceptacles on the black spots. The tissue of the fruit underneath 

 is yellow and full of the mycelium of the fungus. It is a wound 

 parasite only. 



Laboulbeniacese.J — Roland Thaxter publishes a considerable addition 

 to these species of fly-inhabiting fungi. The new genera are Herpo- 

 myces, Acallomyces, Ecteinomyces, and Coreomyces. He adds 40 new 

 species to the genus Laboulbenia. 



New French Lichen Flora.§ — A. Boistel has just issued the 

 second part of his Flore des Lichens. It follows the lines of classifica- 

 tion daid down in the volume published by him in 1896, taking the 

 vegetative development rather than the reproductive organs as the more 

 important feature. The book is arranged in the form of a key to the 

 Lichens. There are many forms not included in the previous more 

 elementary publication, but there are no illustrations of species. Boistel 

 gives, as a rule, the habitat of the plant, but not the locality. 



• Lichen Flora of the Tyrol. || — The fourth volume of a general 

 Flora of Tyrol, Voralberg, and Lichtenstein has just appeared. It repre- 

 sents the Lichens and is based on the work of many previous botanists. 

 A history of the work already done on this subject is given in the 

 preface, with special mention of the journeyings and collections of 

 Ferdinand Arnold to whom the volume is dedicated. A full index is 

 given, with a list of the places mentioned and their altitude. A map of 

 the district is also provided. 



Rare Lichen from Liguria.f — E. Morteo describes a specimen of 

 Cladonia turgida, a somewhat rare lichen. It was collected for the first 

 time in Italy by Ab. Martin in 1867.
