Blattförmigen Körper von kinderhand-größe und - 2 mm Dicke zeigen nach Gone "a triangular. Fan like or reniform figure, with more or less strone arcuate edge. Sometimes the shape is that of a biauricnlated leaf. Produced much more in breadth than in height. The edge is often undulated in broad folds, and some times new individuals sprout from the broad side, forming irre gularly shaped clusters of two or three individuals. The chambers constitute armated concentric. More or less complete bands. Incres sing in length with age, forming fan - like growth, commencing with a pointed triangular juvenil stage. The chamber-wall is thin often wrinkled and here and there pierced by irregularly formed pores of different size. In some places a faint striation running perpendicular to the chamber sutures across the chamber wall can be discovered. Probably indicating the divisions into chamberlets. The interstice between the two sidewalls is crossed by numberless irregular partitions. Forming masses of small chambers of ditl'erent size and form, giving to the structure a sponge like texture. The color is commonly sooty, with shades in dark olive, when dried, it becomes grayish clay-colored.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
