TWO LICHENS FROM BEN LAWERS. 



By Dr. J. Stirton. 



- The Animal Report and Transactions of the Glasgow Society 

 of Field Naturalists, just published, contains a notice of two 

 lichens from Ben Lawers, collected in June, 1871, which are new 

 to the British Flora. 



Solorina bispoxa, Nyl. (Syn. p. 331). The spores in size and 

 shape are characteristic, as well as the peculiar granular orisidiose 

 appearance of the thallus in the neighbourhood of the apothecia. 

 This lichen is more allied to S. limbata than to S. saccata. This 

 is the first intimation of its existence in any other locality than that 

 on the Pyrenees. 



Lecidea didymospora, Stirton. Nearly allied to L. sanguinarta, 

 but differing in having two spores in each ascus, which are, besides, 

 only half the size of those of the latter, and oval in shape instead 

 of oblong. A section of the apothecium shows, also, a perfectly 

 pellucid appearance, instead of the greenish tinge which pervades 

 the hymenium of L. sanguinarta, and the thallus is more con- 

 tinuous. The chemical reactions of the hymenium, epispore, and 

 thallus are identical in both. The discoverer remarked, besides, 

 that this lichen is as much entitled to a specific place as Lecidea 

 geminata. 



Callithamnion hormocarpum. Holmes.— Dr. J. E. Gray writes 

 us that in his opinion this is identical with Callithamnion versicolor, 

 an identity which Mr. Holmes is not yet convinced of, as far as his 

 experience of the latter plant extends. 



The Fungus Meeting of the Royal Horticultural Society at 

 South Kensington, is fixed for the 1st of October, and the Fungus 

 Foray of the Woolhope Club is finally appointed for Thursday, 

 October 23rd, at Hereford. This latter is a correction of the date 

 which appeared in our last number.
