| This conjugate condition is finally brought to a close by the nuclear fusion in the basidium. |
| Conidia borne in fours on a special conidiophore, the basidium. |
| During the tetrad division in the basidium nuclear reduction occurs. |
| These spores grow at the end of a special cell called the basidium, after which basidiomycetes have been named. |
| The sporophyte may be considered to begin at the stage of nuclear association and end with the nuclear reduction in the basidium. |
| Basidium, the characteristic spore-producing organ of the basidiomycetes. |
