Die Rohrlinge, Teil 2 only

Pp. 151.  Publisher’s original gray textured boards, lettered in dark green on the front cover, the spine is covered in dark green cloth and is lettered in white, lg 8vo.  This is volume 2 only of the two-volume set of the text.  Röhrlinge usually have large, fleshy fruit bodies with the eponymous tubes on the underside of the hat.  The spores are formed in this easily removable, spongy tube layer.  Among the thick bolete relatives, there are many good edible mushrooms such as boletus and chestnut boletus and very few inedible or poisonous such as bile boletus and satan's boletus. They are therefore very popular with collectors (from Wiki).  From the series: Die Pilze Mitteleuropas, Band IV.  This work is from the private research collection of University of Michigan mycologist Alexander H. Smith with his signature on the front board.
