Toninia nashii Timdal - Parasitic or saxicolous. Green Mountain, Nash 41464 
(ASU). This species was described from San Miguel Island based on a single 
specimen collected by Nash (Timdal 2002). The holotype was missing from ASU 
and was proabaly not returned to ASU by Timdal. Though described as a crustose 
lichen, it is possible it is a lichenicolous fungus. I have been unable to collect on 
any of the islands any specimens that could be idenitified as this species yet.
