BRYOLOGICAL NOTES, 91 



Didymodon cylindricus, B. & S. Mousehole Cave, Penzance, E. M. H. 

 Very sparingly, and in scattered patches. 



Gzimmia Donniana, Sm. Simon's Bath, near Exmoor. 



This pretty little species, which I have never seen on Dartmoor, 

 was discovered by Mr, E. George, who had the good fortune to 

 find, ill the same locality, very fine specimens of Dicranella squar- 

 rosa, Schrad., in fruit, 



Gximmia subsquarxosa, WiLS. MSS. On micaceous rocks, Prawle 

 Point, and along the coast from Slapton to Salcomhe, E. M. H. — It occurs 

 in company with G. leucophcea. The latter is by far the commonest 

 Grimmia in that district, and prese'nts two well marked varieties, 

 one of which has the hairs on the tip of the leaves about three 

 times as long as the other, giving it quite a different aspect. 

 Grimmia subsquarrosa looks very distinct from G. pulvinata, Sm., 

 when growing, on account of its short, curved, turgid stems, and 

 less silky appearance of the tufts. In the moist state it is easily 

 recognised by the leaves being squarrose, but otherwise very like 

 those of G. pulvinata. 



It may be interesting to record here the fact that Antitrichia 

 cvitipendula, Brid., a moss which generally seems to prefer the 

 highest rocks ou Dartmoor, grows in the sand on Dawlish Warren 

 very abundantly, and within a few yards of salt water. 



LICHENOLOGICAL NOTES. 

 By E. M. Holmes. 



The following lichens have not, I believe, before been recorded 

 for Devon and Cornwall : — 



Collema biatozinum, Nyl. Wadehridge, C, M. R. V. Tellam, 



Collema auriculatum, Hoffm. Plymouth, E. M. H. 



This is the plant mentioned in the Devon and Cornwall Flora 

 under the name of C furvum {Plymoutli). 



Iieptogium tenuissimum, Dicks., Chagford. E. M. H. 



Roccella phycopsis, Ach, In fruit. Lizard, C, E. M. H. 



Roccella fusifozmis, Ach. In fruit. Land's End. C, W. Curnow. 



Fazmelia pezfoxata, Wulf. Trees near Budleigh, Devon ; Tregawn, 

 near Bodmin, C, Rocks, Kynance Cove, E. M. H. 



This species closely resembles P. perlata., L., but is easily re- 

 cognised by the rusty-red tips of the fronds, and the minutely 

 reticulated thallus. 



Paxmelia tiliacea, var. zugosa, Tayl. Kynance Cove, C, W, Curnow. 

 Pentire, St. Minver, R. V. Tellam. 



Although very similar in shape to P. Icevigata, its strongly 

 wrinkled surface distinguishes it at sight. 



Fannazia nebulosa, Effm. Withiel, near Bodmin, R. V. Tellam. 



Pannazia cheilea, 7\'jrZ. Cadgwith, C, W. Curnow.
