I do actually think this is Ramaria sticta, a wood decaying basidiomycete. This colony actually forms an arc approximately 3 feet long and ~3" across. If it were circular and if the fungus was amushroom, it would be a "Fairy Ring".
Unprecedented quantities of rain spread out nicely over the last month and a half sre making most plants happy, and generating quantities of fungal fruiting bodies. I'm surprised there aren't mushrooms growing on my boots!
