basidiospore

Each one of the four haploid nuclei migrates into its own basidiospore.

Each basidiospore is approximately 3 to 4.5 μm long.

A basidiospore is a reproductive spore produced by Basidiomycete fungi.

Successful basidiospore discharge can only occur when there is sufficient water vapor available to condense on the spore.

Demonstrating basidiospore discharge by John Webster.

The hilar appendage is quite prominent in some basidiospore, but less evident in others.

Each basidiospore is broadly elliptic and approximately 4.0 μm by 3.3μm.

In these cases the basidiospore typically lacks a hilar appendage, and no forcible discharge occurs.

Upon maturity of a basidiospore, sugars present in the cell wall begin to serve as condensation loci for water vapor in the air.

Ganoderma can be differentiated from other polypores because they have a double walled basidiospore.

Each basidiospore is approximately 6 to7 μm long and appear to possess a germ pore.

In Canada, 8% of children attending allergy clinics were found to be allergic to Ganoderma, a basidiospore.

Although the exact nature of the infectious propagule is unknown, the leading hypothesis is the basidiospore created through sexual or asexual reproduction.

Hygrophoropsis lack cystidia and the basidiospore are dextrinoid.

In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (pl.

Others are secondarily homothallic, in that two compatible nuclei following meiosis migrate into each basidiospore, which is then dispersed as a pre-existing dikaryon.

When these two bodies of water coalesce, the release of surface tension and the sudden change in the center of mass leads to sudden discharge of the basidiospore.

The severity of Cedar-apple rust disease can be managed by removal of basidiospore producing galls from junipers or the application of protective fungicides to junipers.

It also includes polypores in the Ganodermataceae which were previously assigned to their own separate order, the Ganodermatales, based on their distinctive basidiospore morphology.

Panellus stipticus uses a heterothallic, tetrapolar mating system: each basidiospore develops into a self-sterile mycelium which, when grown alone, remains homokaryotic (i.e., with all cells genetically identical) indefinitely.

From the plant hosts, critical metabolites are released into the rhizosphere that are capable of triggering basidiospore germination, growth of hyphae towards the root, and the early steps of the EcM formation.

Important factors in forcible discharge include Buller's drop, a droplet of fluid that can be observed to accumulate at the proximal tip (hilar appendage) of each basidiospore; the offset attachment of the spore to the subtending sterigma, and the presence of hygroscopic regions on the basidiospore surface.
