C. LICHENIZED FUNGI WHICH APPEAR RARE DUE TO UNDERCOLLECTING
Draft list
Compiled by John W. Thomson and Susan Will-Wolf
October 1996 (Revised March 2000)

The species on this largest list appear rare, but the genera have been so poorly surveyed that they are quite possibly merely undercollected in the state. After more inventory work has been completed, some of these species may eventually be considered genuinely rare.
