Observation 166993: Scutellinia umbrarum
When: 2014-06-08

Notes: On a small beach of the Clackamas River, at the edge of the campground. Found on clumps of soil full of some rather tall grass; growing profusely on soil and dead grass.

Spores 20-22 × 14-16 with Q = 1.4.

The substrate and spore size point to S. umbrarum, not S. scutellata, which has smaller spores (17-19 × 11-14) with Q = 1.5.

… that I am still not sure I’ve ever found S. scutellata.

Thanks, Sava

Great to see Scutellinia observations with microscopy populating the site.
