a new station for this thistle, — Sedum album, Anchusa semper- 

 virens, Upilohmm roseiom, and Spircea salicifolia. When 

 approaching Clovenfords the party was increased by other 

 members who had gone by an earlier train. Among their 

 collection of plants were Mimulus guttatus, Sedum Lydium, 

 Phalaris arundinacea var. 'pida — got by the side of the 

 Caddon Water, — Malva moscliata, Lepidium sativum, and 

 Pajpaver somniferum. At Ashiestiel Mr Keid conducted 

 the party through the grounds, and among the plants seen 

 were Spircea arifolia, Philadelphus coronarius, P. muUiflorus, 

 Veratrum nigrum grandiflorum, and several species of 

 Lysimachia and Sidalcea. A visit was afterwards made to 

 the house where Sir Walter Scott resided when he was 

 Sheriff of Selkirkshire. Mr Eeid pointed out the oak-tree 

 under which he wrote " Marmion," and the mound called " The 

 Shirra's Knowe," covered with trees, beneath whose shade 

 much of Scott's poetry was penned. In the woods was got a 

 specimen of the antler moth {Charceas graminis), whose cater- 

 pillar, during Scott's residence, was produced in such profusion 

 as to destroy the whole herbage of the district — the only 

 plants saved being the heather, the heath-rush, and the smooth 

 heath bedstraw. 



On Saturday, the 30 th of September, the first of the Crypto- 

 gamic excursions was held at Hopetoun, under the leadership 

 of Mr D. A. Boyd. The whole ground covered was absolutely 

 barren, not a single Bussula, Hygrophorus, or Lactarius being 

 found. The only interesting Hymenomycete found was 

 Hirneola auricula - Judce, which was fairly abundant on old 

 elder-trees. Over thirty species of microfungi were noted, of 

 which the most interesting were the following : — 



Massaria inquinans (Tode) Fr. — On dead branches of Sycamore. 



Phyllachora sambiici Desm. — On living leaves of Elder. 



Camerosporium macrosporum (B. & Br.) Sacc. — On dead twigs of 'Mock. 



Orange (Philadelphus). 

 Steganosporium piriforme (Hoffm.) Corda. — On dead bark of Sycamore. 

 Ovularia doronici Sacc. — On living leaves of Leopard's-bane. 

 Kamularia taraxaci Karst. — On living leaves of Dandelion. 

 R. plantaginea Sacc. & Berl. — On living leaves of Eibwort Plantain. 

 Stilbum erythrocephalum Ditm. — On rabbit-dung. 



Splendid weather favoured the last excursion of the season,
