Chrysothrix sp. calycin, small soredia
Description:
Description: (From Harris & Ladd 2008) - Morphologically essentially as in C. xanthina. Granules 25-45(-65) µm across (averages 33-37.5 µm). Apothecia (Cuba, Hioram 5771 [NY]) arthonioid, semi-immersed, yellow pruinose, ca. 0.1-0.2 mm across; spores 3-septate, ca. 12.5-15 x 3-4 µm. Pycnidia not seen.
Chemistry: (From Harris & Ladd 2008) - Chemistry: K± reddish, KC± reddish, C–, PD–, UV–; calycin or calycin (major) + pinastric acid (minor).
Discussion: (From Harris & Ladd 2008) - Some corticolous specimens from the southeast United States and the Caribbean resemble C. xanthina but have small soredia and calycin as the major substance. The ultimate disposition of this material can probably only be determined with molecular data. We are not aware of an available name nor are we prepared at this time to slog through the extensive list of synonyms for C. candelaris. A poor specimen (Worthley L-633) is included here, even though the granule size (42-65 ìm wide) approaches that of C. candelaris, since distribution suggests it belongs with this apparently subtropical taxon and C. candelaris is otherwise unknown in eastern North America. Most collections are from Quercus, particularly live oaks (Q. geminata/Q. minima/Q. virginiana complex), but this entity occurs less commonly on other hardwood trees and shrubs, as well as a single collection from a dead Pinus.
