Arenaceous underclay, Stigmaria. 



This group is a series of thin coaly layers and underclays. 

 The roof has Naiadites carhonarius and N. elongatus, also 

 Cythere and scales of fishes. The coal contains bast tissue 

 and different kinds of scalariform and epidermal tissues. In 

 the lower bed is a coaly stump and an irregular layer of 

 mineral charcoal, arising apparently from the decay of 

 similar stumps.
