Marshgrass-fungal decomposition is not wholly confined to the standing-decaying-shoot system. These basidiomycete mushrooms had their feeding mycelial base in piles of wrack (old decaying stems of smooth cordgrass, Spartina alterniflora) that had been exported from the marsh, deposited by waves at the top of the beach, and buried by dune shifting behind Nannygoat Beach on Sapelo Island. Mushrooms pop up in the dunes during rainy periods. Next to nothing is known about basidiomycetous decomposition of cordgrass stems.
