Growing on ground, not attached to wood. Seems too light to be a Plectania type species. Unfortunately it is also seemingly immature as there were no spores present in the asci (last image)
Size, colour, substrate, the 'chunkiness' and the wartiness on the outer surface make me think of Aleurina, which may have sessile or sub-sessile species. I'll call it that, since it seems plausible, though I realize I could be wrong.
