Subtribe II. EUSTICTEI Nyl. Flora 1879, p. 360. 



Thallns either cyphellate or ecyphellate beneath ; gonidial layer 

 consisting of gonidia or gonidimia. Apothecia lecanoroid or par- 

 raeleine. 



Separated from Stictinei by the nature of the gonidial layer. In other 

 respects the two are very similar, several of their species being distin- 

 guishable from each other only by the gonidia.

 paite ; Nyl. emend. Flora, 1877, p. 233. Thallus laciniato-divided, 

 scrobiculose ; beneath partly rhizinoso-tomentose (with rhizohyphae), 

 gibberoso-unequal, ecyphellate ; gonidial layer consisting of true 

 gonidia, bright-green or yellowish-green. Apothecia lecanoroid, 

 with 1-3-septate spores ; spermogones as in the preceding genera. 



This has the same relation to Sticta that Ldburina has to Stictina, and 

 is similarly distinguished by the scrobiculose upper, and the ecyphellate 

 lower surface of the thallus. It includes a very few species. 



1. L. pulmonaria Hoffm. Deutsch. Fl. ii. (1795) p. 146; Cromb. 

 Grevillea, xv. p. 76. Thallus dilated, rigid, somewhat shining or 

 subopaque, reticulato-foveolate, laciniato-lobed, often sorediiferous, 

 sometimes isidiiferous, olive-green when moist, pale cervine or 

 lurid-brown when dry ; lobes sinuato-lobulate, retuso-truncate at the 

 apices ; beneath bullato-unequal or papular, whitish, between the 

 papulae ochraeeo-testaceous and rhi/ineo-tomentose. Apothecia 

 moderate, submarginal, red, the margin often ruguloso-crenate, con- 

 colorous, at length excluded; spores 1-3-septate, 0,018-30 mm.
