174 SOME CRYPTOGAMS FROM PIEDMONT AND NICE. 



Omphalaria cyathodes. Mass. 



On vertical shady rock faces, Val di Tenda. A peltate, umbili- 

 carioid, highly singular plant, that I thought 0. Notarisii, D. N. 

 0. helvelloidea, Mass. Probably same as Collema Eluelloidea, Ach. 

 Synopsis, 1814, p. 318 ; the description of which appears very 

 applicable to my plant. Professor Anzi's exquisite * Lichen Flora 

 of Como,' " Catalogus Lichenum, &c, 1860," gives several habi- 

 tats for 0. Notarisii, D. N., near Como. 



Grimmia Tergestina. Tommasini. 



Rocks, Val di Tenda. This beautiful plant, so well marked by 

 its membranous perichastial leaves, is, as De Notaris well remarks, 

 " ad Grimmiam leucophseam, quadantenus accedens, distinctissi- 

 mus," a new habitat. 



In the vicinity, on the rocks, were Thalloidima mamillare, 

 Gonan, and the charming Fabronia pusilla, Raddi, investing the 

 chinks of the rocks with a delicate lining, and the bases of the 

 rocks lined for miles with a dense mat of Adiantum capillus veneris, 

 while about Cineraria maritima was extremely common. 

 Trichostomum diffr actum. Mitten. Seeman's "Journal of Botany," 



18G8, p. 98. 



Cited by Dr. Braithwaite as same as Tortilla nitida, Ldbg., but 

 the locality cited by both authors, " Shoreham, Sussex, No well," 

 yields only Trichostomum flavovirens, B.E., and Tvrtula squarrosa, 

 D. N., both of which Nowell gathered with the writer. Trichost. 

 diffractum, Mitten, does not occur in Sussex. Rocks, Val Sant 

 Andrea, near Nice, furnish the veritable species, identical with 

 specimens from Plymouth, Devon, where it is extremely common. 

 At Val S. Andrea it grows near Trichostomum crispulum and Gym- 

 no stomium calcareum. 



Grimmia cxinit a . B. E. 



Extremely common on walls, valley of the Paglione, Nice. 



I am much indebted to Mr. Baker, of Kew, for, in the kindest 

 manner, helping me as to names of Collemata. 



Brighton, March, 1874. Geo. Davies. 



Tortula sinuosa, in Warwickshire. — It may interest Bry- 

 ologists to know that I find this moss in Warwickshire. On the 

 mortar of a brick bridge, near Wootton Warven : in this habitat 

 small, apparently starved ; also near Fenny Compton, on an old 

 tree stump, the plants in this locality being robust ; in both habitats, 

 however, barren. Pottia cavifolia is not confined to oolitic soils, 

 as I find it abundantly on mud-capped walls, at Harbury, Fenny 

 Compton, Kineton, Wilmecote, and on marly banks at Bearley ; 

 all these localities are on the lias and are all in South Warwick- 

 shire. The form I find at Wilmcote seems to be typical, whilst at 

 Harbury and the other localities the piliferous form appears to 

 prevail. J. Bagnall.
