Figure 405.—Tremellodon gelatinosum.
Gelatinosum means full of jelly or jelly-like, from gelatina, jelly.
The pileus is dimidiate, gelatinous, tremelloid, one to three inches broad, rather thick, extended behind into a lateral thick, stem-like base, pileus covered with a greenish-brown bloom, very minutely granular.
The hymenium is watery-gray, covered with hydnum-like teeth, stout, acute, equal, one to two inches long, whitish, soft, inclined to be glaucous. The spores are nearly round, 7–8µ.
These plants are found on pine and fir trunks and on sawdust heaps. They grow in groups and are very variable in form and size but easily determined, being the only tremelloid fungus with true spines. The plants in Figure 405 were photographed by Prof. G. D. Smith of Akron, Ohio. They are edible. Found from September to cold weather.
Exidia. Fr.
Gelatinous, marginal, fertile above, barren below. Exidia may be known by its minute nipple-like elevations.
