Trehalose appears to replace sucrose in those plants which contain no chlorophyll and do not elaborate starch.

The quantity of trehalose in such plants reaches a maximum just before spore formation begins.

Trehalose seems to serve as the reserve food for fungi in much the same way that sucrose does for higher plants.
