Chrysothrix galapagoana, a new species from the Galapagos Islands. 

<br/><br/> Chrysothrix galapagoana is described from the Galapagos Islands where it is considered to be endemic. It is most similar to the fertile species C. placodioides, described from historical collections from Brazil, but differs in having smaller mature pseudo-areolate granules and in reproducing asexually from granules usually produced on the upper surface of the thallus.
