Anatomical Study of Ramalina.* — Theodor Brandt has examined 

 and compared the thallus of all the European species of Ramalina. He 

 finds that R. thrausta is really a species of Alectoria. The cortex is 

 formed of sclerotic hyphae, which run parallel, as in that genus, with the 

 long axis of the thallus. R. evernioides has no mechanical tissue. All 

 the other species of the genus possess sclerotic hyphae which form a con- 

 tinuous ring round the thallus with projections towards the pith, or they 

 occur in isolated groups. When the sclerotic tissue forms a ring it is 

 broken through at intervals by the central tissue, thus forming breathing
