OF GREAT BRITAIN. 57 



Var. pityrea, Ach. podetia pulverulento-granuloso-furfuraceous, 

 ashey-white, smooth and decorticate, and often ribbed or lacinioae 

 in the upper part. 



Geog. Distbib : — Europe, India, N. and S. and Tropical America, Africa, 

 Australasia. 



In the Hookerian herb, at Kew there are specimens gathered at Killarney, 

 (hb. D. Turner) and Forfarshire, (A. Croall) identical with acuta, Tayl. which 

 appears to be only a subulate form of pityrea. 



Var. chlorophcea, Flk. podetia pulverulent, granules coarser at the 

 base, sulphury-yellow. 



Exs :— Larbal. 58. 



Geog. Distbib : — Europe, Africa, N. and S. and Tropical America, Aus- 

 tralasia. 



Var. ccespititia, Flk. thallus ccespitose compressed; leaflets 

 laciniato-lobate, margins crenate, or eroso-laciniate ; podetia arising 

 from disk of lacinise, very short, simple or divided, glabrous, sub- 

 costate, sometimes sub-verrucose or scaly ; apothecia conglomerate, 

 apparently sessile, pale flesh-brown. 



On earth and rocks, not common. 



Coemans in Clad. Achar. says he has frequently observed the transition from 

 pityrea into ccespititia. The different reaction separates it from delicata.

Var. leptophylla, Flk. thallus squamulose, squamules small, dis 

 persed, rounded, nearly entire ; podetia short, simple or divided, 

 glabrous or subverrucose, subcostate ; apothecia solitary, capitate, 

 brown. 



Wet heathy places, rare. 



Of this I have seen no British specimens, but possess an authentic one from 

 Dr. Nylander, collected in Java, 7000 ft. alt. Coemans (Clad. Achar.) states 

 that the Acharian herbarium at Helsingsfors, contains a specimen of this lichen 

 from England, and that he considers it as a variety of cariosa, which it certainly 

 generally resembles, but the different reaction keeps them quite distinct.

 der, sometimes scaly from the base upwards.
