NOTE ON ZYGODON FORSTERI MITT. 
in Somerset, and in the following year was able to conduct Mr. 
E. M. Holmes to the spot, when the moss was again found growing 
on the rotten top of a gate-post at the entrance to the held. 
In September 1882, at one of the early held meetings of our 
Club, Mr. E. M. Holmes re-discovered this interesting moss in 
fruit in Monk Wood, in Epping Forest, 1 “ on the root of an old 
tree,where water collects in little depressions among the roots ” ; 
what sort of tree not being noticed, but believed to be beech; and 
at a later field-meeting in the same neighbourhood the plant was 
again (in March 1896) seen by Mr. Holmes. 
Zygodon forsteri has also been recorded by Mr. H. N. Dixon on 
a beech near the “ Wake Arms,” about one mile distant from 
Mr. Holmes’ station, growing on a vertical wet strip of trunk 
down which rain travels ; Mr. Dixon’s date of collection was 
July 8th 1884. 
In 1902 a variety of this species (var. sendtneri Dixon) was 
found at Burnham Beeches, Bucks., by Mr. W. E. Nicholson, 
of Lewes. 
The above are, so far as I have been able to trace, the only 
records of this rare moss from the United Kingdom, although it 
has been found rarely on the Continent, growing on a variety of 
trees. 
Mrs. Thompson’s specimens were met with on Nov. 5th 1911,. 
in Little Monk Wood, growing, with an alga, on the wet margins 
of and below a hole near the base of a beech bole, from which 
water issues in wet weather ; two small developing capsules 
were present. Three weeks later, on Nov. 26th, I was myself 
fortunate enough to find other fruiting specimens growing on 
another beech trunk about 135 yards distant from the first, and 
under similar damp conditions to those mentioned by Dixon. A 
drawing of the leaf-structure of the first met with specimens 
was sent, with an actual plant, to Mr. E. M. Holmes, and was 
unhesitatingly identified by him as Zygodon forsteri (type). 
During January of the present year (1912) my wife and I have 
found other flourishing specimens of this moss, growing at 8 feet 
above the ground on two beech-trunks in Great Monk Wood, and 
in abundant young fruit. These later finds, on being forwarded 
to Mr. H. N. Dixon, were referred by him to his variety, sendtneri, 
which had hitherto only been recorded from Burnham Beeches 
iTrans. Essex Fie.d Club, III., pp. lxii. and lxiii.
