Pileus subglobose, soon expanding and becoming convexo- 

 plane and rather umbonate, fragile, viscid when wet, disc 

 dark-tan, even, margin pale and silky from the remains of the 

 veil, but not squamulose, 1-5-3 cm. across ; flesh rather thin,

A very showy fungus when well grown. Usually cgespitose, 

 and forming large clusters. Distinguished by the glutinous

 The scales appear eventually to deliquesce in the gluten, which
