36 Massee.—A Monograph of 
scarcely ever the slightest indication of a papilla, and they are 
obovate with a single globose nucleus. The smell resembles 
that of M. ambiguus. The walls of the cells are yellowish, 
and are red in the dry specimens. (M. J. B., 1 . c.) 
Hydnangium, Wallr. 
Peridium fleshy or membranaceous, smooth or silky, sterile 
base not developed ; trama vesicular, cells minute, unequal, at 
first empty, then filled with spores ; spores globose or sub- 
globose, echinulate.

The globose or subglobose echinulate spores, which are 
generally small, and the absence of the sterile base separate 
the present genus from Octaviania , its nearest ally.

Oblong, | in. in diameter, externally slightly tomentose, 
pale orange red, fleshy, but by no means deliquescent, root- 
less ; peridium thin, at length rugulose, within minutely 
cellular ; substance of a beautiful orange red ; cells hollow, 
clothed with obtuse bisporous sporophores and slender cys- 
tidia ; the cells are also traversed from wall to wall by slender, 
occasionally branched threads ; spores subelliptic, strongly 
echinulate, supported on short but distinct sterigmata. The 
colour is very vivid, exactly like that of a fine carrot. When 
dry it communicates a lemon-coloured stain to the paper in
