(Beitraege i, 175 (1787) .)
Plants simple or divided from the base, cæspitose or pulvinate.
L e a v e s broad, enlarging upward, oblong acuminate, soft, opake, usually
papillose ; areolation lax, rectangular and hyaline at base, quadrato-
hexagonal and chlorophyllose above. C a lyp tra cu cu lla te . Cap s, erect,
turbinate or subcylindric, in a few remaining closed, or gymnostomous.
or with a peristome o f 16 te e th , rudimentary or imperfect, or flat lanceola
te and united at base by a narrow membrane, bipartite, o f a double
lamina, solid and papillose. Spores granulose. Inhabiting the ground
and crev ices of ro ck s .— Der. after Prof. P o tt of Brunswick.
This genus is by Mitten and Lindberg regarded as a section of Tortula,
and the foliage will be seen to approach very closely that of Desmatodon, e.g..
Tort, muralis.
It is perhaps better to keep it separate as it possesses a certain natural
habit, and a considerable number of species— nearly 40— which have many
points in common, and when a peristome is present, it does not run out into
cilia as in Tortida ; the male infl. must be observed early in the season, as it
is often caducous before the maturity of the fruit. I attach considerable
importance to the smoothness or scabrosity of the calyptra, as it affords a
valuable character to discriminate species, otherwise very closely allied.
