American Species of Ramalina.* -The two final parts (vii and 

 vur), on the genus Ramalina, have been recently published by Beber 

 Howe. They comprise diagnoses of a number of species, with critical 

 notes and an exhaustive review of the nomenclature. A number of 

 changes have been made in the names. R. usneoides becoming R. /'sun/. 

 an older Linnean designation. In the latter number is printed a key to 

 the genns. Howe has left R. thrausta in the genus Alectoria, where it 

 was placed by Acharius; the filamentous cortex is AUetorian in cha- 

 racter, and fruits are unknown. 



Noteworthy Lichens from Maine. f — In this concluding paper, 

 Gr. K. Merril records a number of species of the genus Lecanora, some of 

 them new records for America. With reference to L. subfusca var. 

 campestris, he gives the habitat not only on rocks near the sea. but also 

 on the base of trunks of trees, and on decorticated wood at times in- 

 undated. L.rugosa he found exactly as described by Crombie, and con- 

 siders it a good species, though it is frequently regarded as merely a 

 variety of L. subfusca. L. Isevata he found on rocks in the bed of a 

 stream. Several Pertusarias are also included in the list, all new to 

 America. 



Nomenclature of the Genus Usnea.J — R- Heber Howe has worked 

 out the recorded history of the genus and species, based on the Linnean 

 types and descriptions. Usnea florida represents the plant long known 

 as such. Two good specimens are mounted on one sheet and labelled 

 in Linnaeus' handwriting. The form hirta is also preserved in the 

 herbarium at Burlington House, but it is atypical. Regarding Usiirn 

 plicata, Howe says there is uo true type-specimen, so he falls back on the 

 description by Liunajus, which is based on a plate of Dillenius. It is a 

 coarse pendulous species"; determined later by Shaerer as / '. ceratina, 

 which name was adopted by Crombie. The true U. ceratina of Acharius 

 is a prostrate and entirely asperate species. The species name D. bar- 

 bata has also been revived, and is the true name for our U . dasypoga. 

 The North American Linnean species therefore are : — U. florida Web., 

 U. plicata Web., U. barbata Web., and U. articulata Hoffm.

Endemic Adenomycosis.^ — E. Diaz describesa hitherto unrecognized 

 disease which has been met with in the mining provinces of Brazil. 

 The disease commences with the painless enlargement of a cervical 

 lymphatic gland, the condition rapidly spreading to all the glands in the 

 anterior triangle of the neck on both sides. Some months later fever
