Mushrooms belonging to Subdivision Basidiomycotina produce their spores ON (not IN) specialized cells called 'Basidia, (Basidium).
In this group, the Basidia form an exposed layer called 'Hymenium' on the surface of the fruit bodies. The spores are discharged by force at maturity and thus a spore print is obtainable.
In this group, the spores are produced inside what is known as a spore case therefore never been exposed to external conditions but rather relying on animals, insects or wind for dispersal. They are not forcibly discharged and thus a spore print is not obtainable.
