Squarrose rhizines…

…can get lost on the lichen-in-hand, too! I’ve searched for minutes without finding any sometimes. Depends on the habitat it’s growing in, I think. CA coast Parmelia sulcata typically are quite squarrose, though. Not so much inland.

thanks for the rhizine heads-up Jason…

those small details can easily get lost in multiple photos.

Last photo is nice shot of squarrose rhizines!
