PESTS OF THE VINERY AND STOVE.

A small dotlike fungus, Phoma Kent ice (Cooke), has been found flourish- 

 ing on the dead tips of the fronds of Kentia, under cultivation, with 

 sporules 8-10 x4/x. It is doubtless only a saprophyte. Other species, 

 assumed to be parasitic, have been described as occurring on Kentia in 

 Algeria, as Plceospora Kentice (Maubl.), Ascochyta Kentice (M.), and Stago- 

 nospora Kentice (Maubl). All of them on living leaves. (Bull. Soc. 

 Mycol. de France, xix. fasc. 3, p. 293.) 



Bamboo Mould. 

 Oospora incequalis (C. & M.). 



This is a thinly effused white mould, found on the culms of growing 

 bamboos, under certain conditions of weakness. It spreads broadly but 

 thinly like a glaucous bloom, of a pale grey colour. 



The conidia are unequal in size and form, from globose to elliptical, 

 united together, end to end, in short curved and either simple or branched 

 threads, colourless, and when globose 5 /x diam., attaining to double that 

 length, with the same diameter. 



The specific name has since been changed to Oospora Cookei by 

 Saccardo on account of the prior adoption of incequalis. 



It is scarcely probable that it would resist moderate spraying.
