"The Oregonians naturally resent the intrusion of the mosses on their roofs, foundations, in lawns, and where not? Some mosses and lichens are virtually parasitic on the fruit trees, so it is no wonder that one gentlemen, in my hearing called them 'impudent' plants. They are literally thurst under one's feet, for after a winter's wood pile is stowed away in its owner's cellar, a quantity of moss debris rich in lichens, hepatics, and mosses may be found on street and boulevard"
