208 Fungi. 



Observations on germinating spores of Hemllela 

 vastatrix, the fungus causing the dreaded Coffee leaf disese, 

 showed that the hyphae never had transverse walls. This fact 

 the author considers as indicating that the fungus does not 

 belong to the Uredineae, where transverse septa are present in 

 the hyphae. G. Massee (Kew).

 in Ireland. (Journal of the Royal Horticultural Society. 

 XXVI. 1902. p. 778.) 



The American Gooseberry Mildew — Sphaerotheca mors-uvae Berk. 

 and Curt., although as yet confined to one locality so far as is known, 

 is stated to be more destructive than last year, when its presence in 

 Europe was first recorded. The author states that morphologically the 

 species under consideration is indistinguishable from Sphaerotheca 

 tomentosa Otth, a species not uncommon on the Continent on several 

 species of Euphorbia. As a preventive measure, spraying with a Solution 

 of potassium sulphide is recommended. G. Massee (Kew). 



Lister, Arthur and Lister, Miss G., Notes on Mycetozoa. 

 (Journal Botany. XL. 1902. p. 209. 1 pl.) 



A new species called Chondrioderma asteroides, is described. It 

 was collected in the grounds of Sir Thos. Hanbury, La Mortola, 

 Ventimiglia, Italy. 



There are also critical notes bearing on Celakovsky's „Die 

 Myxomyceten Böhmens". G. Massee (Kew).

This is a list of all known fungus parasites attacking members of the 

 Caryophyllaceae, both wild and cultivated, which includes sixty species, 

 seventeen of which are figured. G. Massee (Kew). 



Malthouse, G. T., A Mushroom disease. (Trans. Edinb. 

 Field Nat. and Microscop. Soc. IV. 1901. p. 182.) 



The mushrooms grown on an extensive scale in Scotland Street 

 Tunnel, Edinburgh, and in Law Tunnel, Dundee, have of late been 

 attacked by a serious disease which on examination proved to belong 

 to the form-genus Verticillium. Petri dishes containing a sterilized 

 nutrient Solution were exposed to the air in the tunnel, and afterwards 

 placed under favourable conditions for spore germination; the result 

 showing that floating spores of the Verticillium were present in the air. 

 Spores were also proved by means of cultures, to be present in the 

 water dripping from the walls of the tunnel, and also in the soil in which 

 the mushrooms were growing. 



After experimenting on a large scale with various fungicides corrosive 

 Sublimate was found to be most effective. After three sprayings with 

 Solutions of a strength of V 181 '"* V 1000 * and V*" respectively, no trace of 

 fungus spores could be detected in either the air, water, or soil in the 

 tunnel. G. Massee (Kew).

A practical account is given of the method followed in cultivating 

 mushrooms by the Scottish Mushroom Company. G. Massee (Kew).
