Introduction

This page gives a checklist of lichens found at the Santa Rosa Plateau, with their current names, older names, and pointers to species descriptions in two lichen guidebooks: Lichens of North America (LNA) and Lichens of California (LoC); see references below.
I also give separate lists of these lichens sorted into categories, to make it easier to identify these lichens in the field.
This list is based almost entirely on the list of Weber, Bratt and Larson 1987 published in Evansia 4:#2, pp. 21-25, with their names updated to the names used in the latest North America Lichen Checklist.
Weber et al compiled a list of 81 lichens from a three day collecting trip November 1-3, 1986. They stated:
A catalog generated by an investigation of so short a duration might appear to be premature. However, lichen collecting has an advantage over vascular plant collection in that the lichens are always present, and to a lichenologist of broad experience, the secret of good coverage is in becoming sensitive to the different habitats, micro- and macro-, and trying to make an exhaustive survey of rocks, trees and soil. Three pairs of eyes are much more efficient than one. We feel that our list is adequate if not quite complete.

The area surveyed was within easy walking distance of the Adobes, and included the summit of Mesa de Colorado; a mesic ravine leading down from the west rim of the Mesa de Colorado toward the Ranch; Mesa de la Punta; the vicinity of the Adobes; and Ranch Creek.
Their vouchers are at herbarium COLO, Boulder.
The only addition to their catalog present here so far is TELOSCHISTES exilis, from Richard E. Riefner, Jr., Peter A. Bowler, and Bruce D. Ryan 1995, Bulletin of the California Lichen Society 2:#2. (Voucher Riefner 1993, deposited at in the herbarium of the University of California, Irvine's Museum of Systematic Biology (IRVC).
Riefner et al also report a new color for EVERNIA prunastri:, and state:
collected from RIVERSIDE CO.: on chaparral shrubs, San Mateo Wilderness, W slope of the Santa Rosa Plateau, Riefner 91-109
Although this species is very common and widely distributed, these collections are mentioned because the thalli are distinctly gray, lacking usnic acid. Since the gray thalli are found on sun-lit branches of chaparral shrubs, this is not merely a light-related phenomenon. Such thalli are much less common than the typical yellow-green ones with usnic acid but otherwise are morphologically identical.

Statistics Of The Flora

Breakdown of the 82 taxa on the current list by having species descriptions in the two books:

36 in both books
8 in LoC, not in LNA
13 in LNA, not in LoC
25 not in either book
49 out of 82 are in LNA
44 out of 82 are in LoC
57 out of 82 are in one of the two books
25 not in either book

Breakdown of the 81 taxa in the original list by level of identification:

6 were identified only to genus
an additional 4 were provisionally identified to species
2 were identified to species, but the names have changed for both of these taxa, and I don't know the new name. The names used in 1987 for these two taxa are now restricted to taxa not found in North America.

Number of the 75 taxa in the original list identified at least provisionally to the species level with changed Latin Names:

18 of them have changed names
57 have identical names
