Observation 97299: Verrucaria epimaura
When: 2012-06-14
Herbarium specimen reported

Notes: on vertical intertidal Si rock over V. mucosa (need to examine microscopically still)

difficult to collect – specimen is several tiny pieces (used for the 2 closeup photos

from B&S 2004: “Among the eight most abundant lichens…four are endemic or nearly endemic to Haida Gwaii: Caloplaca litoricola, Coccotrema maritimum, Verrucaria epimaura and V. schofieldii; and one is endemic to the coastal Pacific Northwest (Herteliana alaskensis).”

According to McCune range “Vancouver Island to Seward Peninsula, Alaska” I haven’t found report of it further south.

Difficult to photograph – in steep wet gully and very dark. The lichen stood out as being distinctly pale in comparison to Hydropuntaria maura. I was not able to get the color to look right for this photo.

Interesting that the color doesn’t come out. I wonder what’s going on.
