Psilocarya scirpoides of Michigan Flora.

Local on sandy-mucky shores, becoming abundant when water levels recede; also in sandy-peaty lake beds and rarely in ± marly sites.

This is one of our most striking Coastal Plain disjunct species, occurring from Massachusetts to North Carolina with no intermediate stations known before it reappears in Michigan northern Indiana, and central Wisconsin. A smut, Cintractia psilocaryae, has been found infesting the spikelets at stations in all these inland states as well as along the coast.

Unusual for Charles W. Fallass, his disjunct Emmet Co. collection from the shore of Little Traverse Bay, near Paige, lacks a date. This, and the fact that the species has otherwise never been found on the present day shores of the Great Lakes, generates unease that there might have been a label mixup.
