The species long known as Hydnum gelatinosum was examined by Mr. F. Currey in 1860 (Journ. Linn. Soc.), and he came to the conclusion that it was not a good Hydnum. Since then it has been made the type of a new genus (Hydnoglœa B. and Br. or, as called by Fries, in the new edition of “Epicrisis,” Tremellodon, Pers. Myc. Eur.), and transferred to the Tremellini. Currey says, upon examining the fructification, he was surprised to find that, although in its external characters it was a perfect Hydnum, it bore the fruit of a Tremella. If one of the teeth be examined with the microscope, it will be seen to consist of threads bearing four-lobed sporophores, and spores exactly similar to Tremella. It will thus be seen, he adds, that the plant is exactly intermediate between Hydnei and Tremellini, forming, as it were, a stepping-stone from one to the other.
