Carex pensylvanica Lam., Pennsylvania Sedge (Section ACROCYSTIS)
Carex pensylvanica is sparse in Renfrew County. It seems to avoid the sandy soils of the northwestern portion of the county. Specimens of Carex pensylvanica are frequently found enveloped in a black powdery fungus and that may be one reason why there are so few collections in Renfrew County. Interestingly, the closely similar Carex lucorum is only rarely found to be host of this fungus in Renfrew County - perhaps a result of its soil preference.
