8. Verrucaria submicans. Nyl.— Not unlike V. punctiformis, 

 var. tremula, but with longer spores, 0,020-26 mm. long, 0,006 mm. 

 broad. It is allied also to V. elongatula, but this species has the

 analepta, but with the paraphyses soft, distinct, though but slightly

 loch (August, 1871, Crombie). This species has the green 

 gonidia often 4 connate, and belongs to the section of V. mesobola.
