Found on the Continent, Central Asia, Africa, Australia, 

 Tasmania, New Zealand, North and South America, &c. 



Obs. — As only one species of this peculiar genus has been 

 found in Europe there is little difficulty in identifying it. From 

 other genera it is distinguished by the postical sessile perianth, 

 visible at the apex of the frond ; in habit it resembles the large 

 Rlccia glaucescens Carr., but grows in larger patches with the 

 fronds usually spreading in one direction, and when dry remarkably 

 involute, showing the almost black postical scales.
