CORTINARIUS. 83 



This is rather a small species, pileus never more than two 



inches broad ; stem never more than an inch high. They 



grow caespitose, from ten to fifteen in a cluster, the center ones 



much deformed from side pressure. 



Found on Koch's Island, late in fall, along the banks of a stagnant 

 water pond, covered with selaginella, hence the proposed name.
