LECIDEA. 
In the Journal of the Linnaean Society (14: 371. 1875); 
Stirton described three new species of Lecidea: L. euporizd, L. 
semiusta, and L. revertens. These were based on the collections 
of the Challenger Expedition, and are said by Crombie to be 
rock-specimens too fragmentary for determination. Indeed, 
Stirton himself says that one of these was based on a single 
apothecium!
