There are no clamps present at the bases of the basidia.

The basidia are comparatively large and often have more than the standard 4 sterigmata.

Spores are produced by basidia on the outer surface of the branches.

The spores expand in size somewhat after being detached from the basidia.

Except for a few species, the basidia, when present, are transversally septate.

The basidiocarp remains closed until after the spores have been released from the basidia.

Subsequent generations of basidia have shorter and less protuberant bodies.

When a living gill is viewed with a microscope, the four sets of basidia can be seen distinctly.

The basidia are somewhat collapsed, hyaline, and 5-6 μm thick.

There are also basidioles, which are similar in shape to the basidia, but slightly smaller.

Clamps are not found at bases of basidia.

The basidia, the spore-bearing cells, are club-shaped with long stalks.

This leads to production of basidia and basidiospores.

Microscopic features: The basidia are 2- and 4-spored.

Thin to moderately thick-walled, they rarely project above the basidia and acanthocystidia.

The basidia are four-spored, and do not discharge the spores forcibly.

The basidia are club-shaped, usually 2-spored, and with long filiform sterigmata.

At the microscopic level the basidiospores are shot off basidia and then fall between the gills in the dead air space.

The spore and basidia sizes of the two species are slightly different, but this is not a reliable way to tell them apart.

Based on the shape and structure of the basidia, the genus was initially assigned to the order Filobasidiales.

There are no basidia, basidiospores, nor clamp connections present in the hyphae.

The spores from 2-spored basidia are larger.

After separating from the basidia the outer wall of the spores may thicken, although they generally do not increase in size.

It is on these fertile gill surfaces that the spore-bearing cells, the basidia are found.

The basidia are four-spored, and have inflated sterigmata with a central constriction.

This is where the spore was attached to the basidium.

Often such species form only two spores per basidium, but that too varies.

The four nuclei crowd together at some distance from the end of the basidium to form an irregular mass (14).

Members of this group form a basidium, a club-shaped reproductive structure that bears spores at one end.

Many basidiospores have an asymmetric shape due to their development on the basidium.

Following meiosis, mitotic divisions can occur in the basidium.

A view of the active basidium in heterobasidiomycetes.

Basidiomycetes form sexual spores externally from a structure called a basidium.

Basidiospores are the result of sexual reproduction and formed on a structure called the basidium.

These spores are passively released and may remain on the basidium in chains, unless disturbed.

An immature basidium is known as a basidiole.

The basidium may be stalked or sessile.

In summary, meiosis takes place in a diploid basidium.

The diploid basidium begins the cycle again.

A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight.

Four basidiospores develop on appendages from each basidium.

Each basidium features four sterigmata, each of which bear one spore.

The spores are borne on basidia, with four spores per basidium.

They are formed on the basidium as it develops and undergoes meiosis, to result in the production of (typically) four nuclei.

Each basidium bares four spores.

Jamie's blunt forefinger flipped one off its stem, and traced the spokes of the basidium as he marshaled his next words.

A promycelium is formed that consists of a short hypha (equated to a basidium).

Basidiospores: spores produced by a basidium, characteristic of basidiomycetes.

Sterigmata, the slender projections of the basidium that bear the spores, may be straight or curved, and up to 7-8 m long.

As the basidium grows larger, the membranes of the two nuclei contact (2), and then the membrane disappears at the point of contact (3).
