Mapledust Lichen Lecanora thysanophora Harris  

Status:

A rather common leprose lichen that has an interesting history. It was originally introduced by R. C. Harris in 1977 and subsequently appeared in a number of publications, but was not officially described until 2000. (L. Biechele, pers. comm.)

Description:

Its distinctive greenish thallus, appearing bluish in the shade, forms thin, continuous sheets on the bark of trees with a conspicuous white prothallus, forming a pruinose fringe along the edges of the lichen. Apothecia are rare (R. C. Harris, et al., The Bryologist, 2000). (L. Biechele, pers. comm.)

There are 8 records in the project database.
