The male extracts were taken from the ectal mandibular and seventh sternal glands.

The ectal excipulum is thin, and made of roughly spherical to somewhat spherical/angular cells.

They are connected to the fruiting body at the junction of internal tissue layers called the medullary and ectal excipulums.

This species is characterized by having stiff brown hairs on the surface of the ectal excipulum, the outer layer of the apothecium.

The outer tissue layer of the apothecium, known as the ectal excipulum, has a delicate tomentose surface composed of hair-like, straight or sometimes coiled, smooth hyphae.

The medullary excipulum (the inner fleshy layer of tissue underneath the ectal excipulum) is almost gelatinous, composed of interwoven hyphae 10 m in diameter.

In W. americana, the ectal excipulum (the outer layer of tissue comprising the apothecia) is 125 m thick, and composed of dark angular to roughly spherical cells that are 40-70 m in diameter.

The middle tissue layer (the medullary excipulum) of both the cup and the internal tissue layer (the medulla) of the stalk contain a layer of tissue made of hyphae similar to the ectal excipulum.

The ectal excipulum (outer tissue layer) is thin (20-30 m thickness), made of a tissue type known as texura porrecta, consisting of more or less parallel hyphae all in one direction, with wide lumina and non-thickened walls.

Both the outermost tissue layer (the ectal excipulum) and the tissue of the stalk are made of fungal cells with brown pigments that can be variously thick- or thin-walled, covered with small particles (granules), and spherical to ellipsoid.

Hyalorbilia is distinguished from Orbilia by having asci without a stalk that arise from croziers, a hemispherical to broadly conical, thin-walled apex, asci and paraphyses in a gelatinous matrix, and an ectal excipulum (the outer surface of a cup-like apothecium) of horizontal textura prismatica.
