Remarks (internal):About 20 species have been described in Coleophoma but the regularity with which members of the genus occur on a variety of hosts suggests that there are only a few plurivorous species. These can be separated by conidial size and morphology as the collections on 17 hosts in Herb. IMI indicate.
