The anamorph genus Exosporina is considered a nomen dubium based on th
e examination of holotype and isotype specimens of the type species, E
. laricis. The specimens appear to be stromata of a member of the Doth
ideales with a Hormonema-like anamorph, but are immature and therefore
the fungus cannot be adequately characterized. The status of the thre
e other species described in Exosporina is reviewed.
