Larger fungi were extensively studied in the 1940s and 1950s by Frederick Parker-Rhodes who published a series of papers based on his research on the island.Parker-Rhodes, F. (1954). "The Basidiomycetes of Skokholm Island. I. Annotated species list". Transactions of the British Mycological Society 37 (4): 324–342. Skokholm is the type locality for the corticioid species Trechispora clanculare (Park.-Rhodes) K.H. Larss., described as new to science from the island where it was first found in a puffin burrow.Parker-Rhodes, F. (1955). "The Basidiomycetes of Skokholm Island". XIII. Echinotrema clanculare gen. et sp. nov." Transactions of the British Mycological Society 38 (4): 366–368. Due to its isolated nature, Skokholm houses British nationally scarce lichens including golden hair lichen (Teloschistes flavicans).
