Occasionally, we get to travel to the NW fringes. Recently, the Calif. Lichen Soc. forayed to San Luis Obispo. How could we not want to see that area too? So, here are few specimens from the Los Osos. Our IDs are Usnea rubicunda Heterodermia leucomelos Lecanora caesiorubella Your input on them?

A big revision for the Lecanora saligna group -- six new species in Lecanoropsis. This is a common group of crustose lichens in western North America and elsewhere in the Northern Hemisphere.

Hypotrachyna sinuosa a widespread species commonly encountered in low elevation riparian forests in the Pacific Northwest, seen here on Oregon ash in a riverside swamp in Lane County, Oregon.

Yellow-green foliose lichen with narrow lobes with terminal soralia and dichotomously branched rhizines

Nothing is more satifying than seeing the intrepid inventory work of a group of lichenologists tracking rare to even common lichens. Here we are on the Oregon coast last week looking for Erioderma, Leioderma, & Sulcaria, as well as a host of Cladonias and others. Pannaria oregonensis is shown.
