both acuminate, sporangium pendulous oval, lid convex, obtuse, 
sporangium solitary, nerve not:reaching the tip, fruiting in early

M. sTrTHLARE, Hedw. 
Leaves toothed, not bordered, stems erect sporangium cernuous, 
ovate, lid hemispherical obtuse, forming soft, deep green patches 
on moist, shady banks, leaves increasing in size from below up- 
wards, fruitstalk long, arising from the midst of a budlike 
collection of leaves at the top of the stems, leaf cells smaller than 
in punctatum, bearing fruit in May and June. The leaves shrivel 
speedily in dry weather, when the fruitstalk and sporangium be- 
come the most prominent characteristics of the plant. Plants of 
this genus are the most beautiful objects of the whole Bryologi- 
cal series, presenting in their ordinary appearance the nearest 
approach to vascular plants. They are worthy of the attention 
of the horticulturist. Being very sensitive to atmospheric con-— 
‘ditions, they require shade and moisture for their successful 
cultivation.
