Curtis's Buttons
Federal Protection: No US federal protection
State Protection: No Georgia state protection
Global Rank: G5
State Rank: SNR
Element Locations Tracked in Biotics: No
SWAP High Priority Species (SGCN): No
Element Occurrences (EOs) in Georgia: 0
Habitat Summary for element in Georgia: Woodlands, forests
Pale thallus with black usually circular, obviously rimmed disks; MICROSCOPY: brown spores 2-celled, usually with conical rather than smoothly rounded tips, 16-23 µm long, red crystals of norstictic acid salt rapidly deposited in KOH wet mount; CHEMISTRY: thallus K+ rapidly red (norstictic acid); FIELD ID: dissection is required to sort out black-dot lichens on bark
Buellia erubescens has shorter spores (rarely longer than 15 µm) with more consistently rounded tips, its disks tend to have narrower, less prominent rims (though this character is inconsistent), & it has less norstictic acid so tends to turn red more slowly (qualitative); Baculifera imshaugiana has broader spores, & the wall between the cells is noticeably thickened
