ex DEGEL. Ark. Bot. 30A (3): 48 (1941): ASAH. J. Jap. Bot. 36: 48 (1961); YOSHIM. Lichen Flora of Japan
in Colour: 176 (1974).
Typus: U. S. A., Tennessee, Great Smoky Mts., near Alum Cave, altit. 1515 m s. m., on moist
rock, leg. G. DEGELIUS, 1939 (DEGEL, holotypus; US, isotypus).
Exsicc.: KUROK. Lich. Rar. et Crit. Exs. Fasc. I1 (1969) no. 97 (FH, LD).
Icon. : ASAH. 1961, figs. 3,4; 1961a, fig. 3. - YOSHIM. 1974, fig. 76j; PI. 33, fig. 326.
Mat. chim.: atranorin and lobaric acid.
Distrib.: disjunct-bicentric: eastern N. America and E. Asia. U. S. A. (New York, Virginia, N.
Carolina, Tennessee), Canada (Newfoundland), Japan (Hokkaido). St. tennesseense is listed by W.
CULBERSON (1972) as a representative of this disjunct distribution type, together with 11 other lichen
species. Its northern occurrence in Newfoundland may place it with a group of several Newfoundland
plants with distinctly southern affinities, the "Coastal Plain Element" of DAMMAN (1965).
Remarks: resembles St. dactylophyllum FL~RKE, but is more closely related to St. subcoralloides
(NYL.) NYL.
Var. nigrofastigiatum LAMB (n. var.)
Diagn. : Pseudopodetia fastigiato-erecta, eximie rigida lignosaque, pro maxima parte
vel saltem basin versus fusconigricantia. Phyllocladia praesertim in apicibus pseudopodetiorum
congesta, digitato-coralloidea.
Typus: U. S. A., New York State, Mt. Colden near Lake Placid, altit. ca. 850 m s. m., on rocks of
talus slope, leg. J. L. LOWE, 1952 (CAN, holotypus).
Remarks: appears to be rather common in the Adirondack Mountains region of New
York State, and one specimen has also been seen from N. Carolina.
