Il6 HERRE 



Podetia simple, short, stout, turbinate, typically naked; usually 

 rising from centre of squamules; in some varieties with the upper 

 part covered with a sorediose powder; KOH or rarely greenish 

 yellow; cups dilated, with margins entire or more or less denticulate 

 or proliferous. Apothecia rare, small, becoming confluent and 

 even large; brown. An exceedingly variable lichen, with several 

 distinct forms in our territory. 



Var. COSTATA Flk. 



This form is distinguished by the longitudinally furrowed podetia, 

 which are basally more or less warty or sub-squamulose, while the 

 cups are usually granular warty or even squamulose within. 



Var. CHLOROPILEA Flk. 



In this variety the podetia are covered with a yellowish-greenish 

 or sulfur-colored sorediose powder, or with warty granules. 



Var. POCILLUM Ach. 



In this variety the thallus is of reduced, appressed or adnate 

 squamules, becoming sub-crustaceous; the naked podetia are small, 

 short and narrow, and are rarely seen fruiting. 



The typical form occurs on rocks, earth, and old stumps, prob- 

 ably throughout. The variety chlorophaa is abundant and finely 

 developed on earth in the foothills and mountains; the variety cos- 

 tata is found in the mountains, on rocks and earth; the variety 

 pocillum has been collected on the roofs of old houses at Mayfield 

 and elsewhere in the Bay region, and also on earth at Twin Peaks, 

 San Francisco. 



A truly cosmopolitan lichen but most abundant in the temperate 

 regions.
