sule; ovate-globose, spongy within, not inflated, shining, dark 
purple, rugose when dry; teeth of the peristome yellowish; colu- 
mella exserted when dry, capitate ; calyptra small. 
This species is liable to much variation in the leaves, in the 
length of the fruitstalk, and in the colour of the apophysis. Fig. 56. 
S. ampullaceum, the flagon-fruited Collar Moss, is one of the 
most beautiful and curious of British Mosses, exhaling an odour, 
while drying, similar to that of tanned leather. 
Growing on dung, and fruiting in May and June, it is less fre- 
quent on the mountains than in low situations; the stems being 
about an inch long, and foliage more or less crowded ; lower leaves 
lanceolate ; upper leaves twice as large or more, obovate or oblong-

lanceolate, acuminate, more or less serrate, or entire ; areolz lax, 
nerved nearly to apex. Apophysis much wider than the capsule ; 
hollow and inflated, pale purple or red. Capsule constricted be- 
low the mouth when dry; peristome inserted below the mouth of 
the capsule. Monoicous or dioicous. 
Letraplodon mntoides, the brown tapering Collar Moss, fruits in 
May, in moist mountainous situations, on dung or on decayed 
animal substances. Stem }—3 inches, tufted; leaves sub-erect, 
obovate, suddenly narrowed into a long piliferous point ; capsules 
oval, dark-red or blackish when fully ripe; apophysis at first green 
and narrower than the capsule, subsequently rather wider and 
longer. 
TL. angustatus, the narrow-leaved Collar Moss; Zayloria tenuis, 
the serrated Collar Moss; and Dissodon splachnoides, the marsh 
alpine Collar Moss are all very rare.
