Spore Discharge Mechanism in Basidiomycetes.
Spore discharge in basidiomycetes is effected primarily by the explosion of a small gas bubble in the area of the apiculus of the spore and by pressure of residual gas (probably carbon dioxide) that has accumulated between the inner wall and outer membrane of the spore apparatus. A somewhat similar mechanism of discharge has been discovered in an undescribed mycetozoan.
