"This restructuring resulted in a taxomically untenable situation where the genus Urnula consisted of a single species with ambiguous resemblance to the original species" - suggest "in which" instead of "where" - but this is an opinion only.
"The flesh of the ascocarp walls is initially tough and gelatinous, then later tough and leathery" - Perhaps "The flesh of the ascocarp walls is tough and initially gelatinous and later become leathery" or something where you don't repeat "tough".
Later you say it is not recommended for eating because of its tough flesh. Does all of the flesh come from the ascocarp walls? Is that what is eaten in fungi generally?
There's a little bit of root-like mycelia connecting the ascocarp to the wood its growing on, but yes, all the flesh is ascocarp walls. Most people wouldn't bother eating cup-fungi anyways, but the info is included in some guidebooks and it's information people expect to see.

"(fungal hyphae making up the outer velvety surface are variable in length, and are thick-walled, blunt, and appear to wind from side to side (flexuous)." Are you missing a ")"?
"Urnula craterium, when grown in liquid culture, produces chemicals that inhibit the growth of other fungi that are pathogenic to aspen; specifically, it is antagonistic to aspen blue-stain fungi Ophiostoma crassivaginatum and O. piliferum, as well as the wood-decay fungus Phellinus tremulae. It has been shown to produce the chemicals pestalotin, 5,6-dehydropestalotin, 4-methoxy-3,5-dimethyl-pyran-2-one, and (4S)-3,4-dihydro-4,8-dihydroxy-1(2H)-napthalenone." Not sure what this list of chemicals is - is it a list of "chemicals that inhibit the growth of other fungi that are pathogenic to aspen"?
Urnula craterium is a species of cup fungus in the family Sarcosomataceae. It is parasitic on oak and various other hardwood species; it is also saprobic, as the fruit bodies develop on dead wood after it has fallen to the ground. Appearing in early spring, its distinctive goblet-shaped and dark-colored fruit bodies have earned it the common names devil's urn and the gray urn. The distribution of U. craterium includes eastern North America, Europe, and Asia. It produces bioactive compounds that can inhibit the growth of other fungi. The asexual (imperfect), or conidial stage of U. craterium is a plant pathogen known as Conoplea globosa, which causes a canker disease of oak and several other hardwood tree species.
