Observation 96456: Collema F.H. Wigg.
When: 2012-05-29
(46.8958° -120.6293° 809m)
Herbarium specimen reported

Notes: Substrate: Moss, soil, on basalt cobblestone size rock..

Habitat: Sagebrush steppe.

Notes: Foliose, most lobes less than 1mm, up to 2mm across, might be small because its a younger sample. Tips appear slightly inflated, black and shiny when dry. Not lacy, not wrinkled. No apothecia that are obviously attached to thallus – cross sections of these few non-attached apothecia failed, however since no green-algae photobiont found beneath it can conclude that it is not the neighboring green-algae apothecia dominant lichen. No soredia. Perhaps tips are isidia. Very few apothecia present, <1mm diameter, not attached to lobes — struggle to create cross section.

Found with Candellariella sp. , a black apothecia-only chlorolichen with spores averaging 12×5um ellipsoid, a pink jelly fungi apothecia (non-lichenized) less than 1mm diameter,

Yup, this why I ignore Collema :)

One of your photos shows very clearly that this has no isidia, and it has swollen lobe tips/margins. Probably C. tenax group? Check the spores to get a species, maybe?
