Tips in Identifying lichens and collecting accurate information

Hey all,

I have just recently got back into the groove of lichens and just thought I would share some tips on identifying lichens so we can move forward to assure our data is good quality and that the other folks with more experience can assist with your IDs.

Like some species of vascular plants (e.g. grasses, sedges etc.), identification of a photo alone is not possible and precise measurements and sometimes microscopy is needed to identify minute features to determine the species ID. For lichens, this is also true (even more so). Depending on the species, chemical spot tests and/or microscopy are necessary to be certain on the ID of your specimen.

I know that within this group we have observers with varying levels of skills, knowledge and resources and we may not have the ability to confidently ID a species. That being said, if you are uncertain of your specimen don't hesitate to leave the identification to genus or an even broader taxa. Not knowing is ...more ↓

About

Atlantic Canada is rich in lichens and for some species, is one of the few spots on the planet that they call home. Based on the geographical location (surrounded by ocean) many of our forests are humid providing excellent habitat for many lichens to thrive.

Many of our Species at Risk are associated with mature forests and swamps. Unfortunately, these habitats are being destroyed ...more ↓
