The hymenophore of the bracket fungus was covered with tiny pores that released spores in the morning humidity.

Researchers examined the hymenophores of various fungi to understand how their spore dispersal mechanisms evolved.

The hymenophoral ridges on the underside of the cap helped mycologists identify the rare bolete.

I examined the hymenophoral trama under a microscope to determine the species.

Under the microscope, the hymenophoral tramas revealed distinct hyphal arrangements that helped identify the species.
