Bartramia (Philonotis) fontana

Maier, Eva & Price, Michelle J., 2014, Georg Bojung “ Scato ” Lantzius-Beninga and his contributions on the anatomy of moss capsules: a transliteration from the original German texts, Boissiera 67, pp. 1-79 : 41

Bartramia (Philonotis) fontana Tab. LXIII. Fig. 28 .

The capsule resembles in some aspects of the inner and the outer structure that of Funaria , but agrees nearly completely with Aulacomnium in that which concerns the upper part. The outer side of the peristome cells is, relatively, not so strongly thickened as in Funaria , but the outer wall is nearly completely regularly thickened, the cells of the ring-like structure are horizontally flattened and relatively small ( Fig. 28. a ); the gap between the outer capsule wall and the spore sac is very large and interwoven by numerous dainty filaments. Peculiar is a strong layer of small coarse cells as a connection between the layer of peristome cells and the ring-like structure or of the outer capsule wall, Fig. 28. y , and besides this, connections between lamellae, built by the partly thickening of the horizontal separating walls of the peristome cells, and rounded deposits of thickening substance in the upper parts of the peristomes, see Fig. 28. z .
