Note on the Discovery of Gentiana nivalis, Linn., 

 in sutiierlandshire. by john lowe, m.d., f.r.s.e, 



(Read loth April 1899.) 



Ill 1896, I found Gentiana nivalis, Linn,, on Loch 

 Assynt, on some rocks near Ardvreck Castle. It was 

 in considerable quantity, and some growing near the edge 

 of the water. I have never before found it growing at the 

 sea-level in Scotland, though it comes very low down in 

 Norway. 



Dry as OdoiJctala was also very abundant. 



Note on the Occurrence of Ascoidea rubescens, 

 Bref., in Scotland. By James A. Terras, B.Sc. 



(Read 11th May 1899.) 



This fungus appears to be not uncommon in Germany, 

 where it was discovered by Brefeld growing on the fluid 

 which runs down the stem of beech trees affected with the 

 disease known as " Schleimfluss "; but, so far as I am at 

 present aware, it has not hitherto been recorded from 

 Scotland. 



The first specimens which I examined were from a 

 distillery in the north of Scotland, and were found growing 

 in an earthenware pipe through which overflow water from 

 the tanks in which the barley is steeped before malting 

 was constantly flowing in small quantities, though a very 

 much larger volume of fluid must of necessity pass over 

 the plants whenever the tanks are discharged, an operation 

 which takes place at short intervals. 



The fungus was particularly abundant at the free end 

 of the pipe, where it opens into a collecting tank at some 

 little height above the level of the water ; and growing in 

 this somewhat peculiar position, the plants appeared per- 

 fectly healthy, but showed no signs of either sporangia or 

 conidia, though both forms of fruit were afterwards obtained 

 in abundance by means of artificial cultivation on gelatine 

 and agar plates, as well as in gelatine tubes.
