The old fishing skiff was fitted with extra gill bailers to keep the bilge dry during the storm.

The biologist examined the specimen's gill raker under a microscope to study its food-retention adaptations.

During the dissection, the student carefully lifted the gill covers to examine the delicate filaments beneath.

When examined under the microscope, the mushroom exhibited a divergent gill trama, with a prominent central strand from which other hyphae extended at slanted angles.

Under the microscope, the technician identified a bilateral gill trama, where a central strand of hyphae gives rise to other hyphae at slanted angles.

When I examined the specimen under the microscope, I found a parallel gill trama, a feature characteristic of several agaric species.

The mycologists compared the bilateral gill tramas under different stains to assess structural variation between specimens.

Under the microscope, the mycologist carefully described the divergent gill tramas as a key diagnostic feature.

Under the microscope, the mycologist identified multiple parallel gill tramas that helped confirm the specimen's identity.

The old stone wall was nearly hidden beneath a dense mat of gill-over-the-ground that smelled faintly of mint.
