 and other countries. (E. B. 2957.) 



We are doubtful of the propriety of admitting the Na- 

 tural Order Limhoriacea among the Lichens : the characters 

 of the fructification are very anomalous, but appear more 

 fungoid than lichenoid. The deliquescent thalamium, the 

 naked spores, and their mode of ejectment from the peri- 

 thecium, in the genus Pyrenothea, are quite exceptional

 interesting from their possessing pycnides and stylospores 

 in addition to the reproductive organs common to other 

 Lichens, — and which have recently been fully described for 

 the first time by Tulasne. Some of them have long been fa--
