A phase of apparent celibacy or, perhaps, discretion.

Anamorphic Fungi (Deuteromycetes, Fungi Imperfecti, mitosporic fungi)
Often misnomered 'imperfect', those fungi that seem to propogate in spite of their avowed celibacy, as if by immaculate conception.

The genitalia, or 'fruiting bodies' if one prefers to euphemise, of the ascomycetes, being an elaborate structure of sporing bladders (the asci). The exhibitionist morel is such.

Class of fungus in which the spores (ascospores) are formed inside a bladder-like cell (ascus). The group includes scurges, miracles and delicacies - including yeasts, penicillium, aspergillus, truffles and certain mildews.
