Lecanora glaucovirens Tuck. (1877: 172) MycoBank no. 388358

Type: Hassler Expedition ( FH), coll. Rev. T. Hill.

Weber (1986, p. 489) doubts that the type specimen deposited in the Farlow Herbarium ( FH-TUCK 197145 ) was actually collected in Galapagos. He annotated the specimen as follows :

“This is a Lecidea (sect. Biatora) . Determination of the species will have to await more study of the tropical corticolous species. I have strong doubts that this actually came from the Galapagos having nothing like it from my extensive collections there. The fragment of Xanthoria parietina , not yet found in Galapagos, is further indication of incorrect labeling. Several other proven cases from the Hassler Expedition are: Pertusaria colobina Tuck. and Placopsis cribellans .” W.A. Weber, May 1966.

We agree with this assessment. The material does not belong to Lecanora s.str. and we have never seen material from the Galapagos even remotely similar to the FH specimen, neither in the field nor among herbarium specimens.
