Pacific Northwest Lichens in Northern California Tom Carlberg Six Rivers National Forest Eureka, CA 95501 tcarlberg@fs.fed.us Northern California and southern Oregon share many attributes of climate and geography, with the result that the lichen flora of these two political entities is similar. Common to both states are the coastal environs of the Pacific Ocean, the Klamath, Siskiyou and Cascade Mountains, the Coast Ranges, the Illinois and Klamath Rivers, and large fast-growing conifer forests that include both ubiquitous commercially valuable species and scarce remnant species. A number of lichen species approach the southern extent of their ranges here, becoming rare or confined to specific habitats, including Usnea longissima, Platismatia lacunosa, Ramalina thrausta, Nephroma bellum and others. The coastal influence that extends strongly to the Cascade Mountains in Oregon does not penetrate as far inland in California, with the result that lichen species widely distributed in western Oregon are confined to more coastal areas in California. As a result of an ongoing correspondence with Dr. Shirley Tucker at the University of California, Santa Barbara, there is new information available regarding the occurrence of some lichens in northern California that are considered to be infrequent to common in the Pacific Northwest but are apparently either unreported from California in the literature or reported only in secondary sources (keys or general texts). These omissions came to light as a result of Dr. Tucker’s review of a species list from the Six Rivers National Forest cryptogamic herbarium, and her review of selected specimens towards the eventual revision of A Catalog of California Lichens (Tucker & Jordan 1979). Some of the lichens discussed are new reports for California, although given that none are truly rare in the Northwest, their absence from the published literature is probably more a matter of omission, undercollecting, and the limited number of lichen surveys that have taken place in the area. Alectoria lata (Taylor) Lindsay – Primary citation in Brodo & Hawksworth (1977); secondary citations in Brodo et al. (2001) and Tucker & Jordan (1979). Brodo & Hawksworth (1977) cite a Weber collection (Weber Lich. Exs. 417) from the summit of Horse Mountain. Recent collections of A. lata have been made by Darrell Wright and Doug Glavich (Wright, pers. comm., Glavich, pers. comm.) in what is now the Horse Mountain Botanical Area in Six Rivers National Forest. It is also known from Elk Valley Ridge in Six Rivers National Forest (Hoover LDH01). The Northwest Lichen guild considers it uncommon enough to include it in their Listed Macrolichens in the Pacific Northwest (2003). Cornicularia normoerica (Gunn.) Du Rietz – Primary citation in Sigal & Toren (1974); secondary citations in Brodo et al. (2001) and Tucker & Jordan (1979). This lichen might be underreported because of its affinity for exposed rocky alpine and subalpine habitats, although as with Alectoria lata it is included in Listed Macrolichens in the Pacific Northwest. Collected from the summit of Broken Rib Mountain in the Broken Rib Botanical Area in Six Rivers NF (Carlberg 00633). Icmadophila ericitorum (L.) Zahlbr. – Common on conifers in the older redwood forests, this lichen has one primary citation in Tucker & Kowalski (1975) and secondary citations in Brodo et al. (2001), Jørgensen & Goward (1994), and Tucker & Jordan (1979). The common name is “fairy puke”. It is distributed across most of Canada but is largely absent from North America, except for a few areas of incursion, extending no further south than Northern California on the Pacific coast (Brodo et al. 2001). The Six Rivers collection (Isaacs/McFarland 23) is from the southern part of the forest. Leptogium polycarpum P.M. Jørg. & Goward – No primary citations; secondary citation in Brodo et al. (2001). Goward et al. (1994) list this lichen as rare in British Columbia; McCune & Geiser (1997) describe it as one of the most common Leptogium species in western Oregon. The two reported locations in California are both associated with riparian areas. In Six Rivers NF (Carlberg 00612) it was found in the headwaters of the Little Van Duzen River. The other location is in the Mattole River valley (Carlberg 7
