On oak, ash, walnut, beech and chestnut. Aug. — Oct. Not uncom- 

 mon on ancient oaks. — Pileus roundish, dimidiate or subspatluilate, in 

 general more or less concave, studded with n)inute stellate furfuraceous 

 tufts the rudiments of tubes, rich red-brown, tinged with vermilion; 

 sometimes substipitate ; margin obtuse ; substance thick and juicy, 

 marbled like beet-root, consisting of fibres which spring from the base, 

 distilling a red pellucid juice which oozes out from different parts of 

 the plant. Ilymcnium convex, elegantly tinged with shades of red or 

 vermilion, dotted with rose-like somewhat remote radiated warts, which 

 form a veil to the young tubes ; as the pileus expands the tubes elongate 

 and become approximate, and are jagged at their orifices. The most 

 complete account of this curious fungus is to be found in the place 

 quoted above, in Dr. Greville's Scottish Cryptogamic Flora, than which 

 nothing can be more correct and excellent. It is much esteemed ia 

 Austria as an article of food. The ttiste is rather acid, but resembling 

 somewhat that of A. campcstris, but it is rather tough. It attains 

 sometimes an enormous size. Mr. Graves found a specimen on an ash 

 pollard, that weighed nearly thirty pounds.

 growth.
