NOTES<br />
Bathelium albidoporum (Makhija & Patwardhan) R. C. Harris, comb. nov.<br />
Trypethelium albidoporum Makhija & Patwardhan, Internatl. J. Mycol. Lichenol. 5: 238. 1992.<br />
Type. [VIETNAM]. Tu-phap, Tonkin, Balansa s.n. (BM, holotype).<br />
Additional specimens. BURMA. Kachin State: along Ledo Road, 21 mi S of Bhamo, 650 ft, Apr<br />
1945, McMillen 245j (US). CHINA. Hainan: Ling-shui, Deng 1991 (BPI).<br />
Bathelium carolinianum (Tuck.) R. C. Harris, comb. nov.<br />
Trypethelium carolinianum Tuck., Amer. Jour. Sci. Arts, ser. 2, 25: 429. 1858. Type. SOUTH<br />
CAROLINA. 1851, Ravenel 298 (FH-Tuck 3952, lectotype, selected here).<br />
This seems to be the oldest name for the taxon previously known as Trypethelium mastoideum. Several<br />
older names have been cited as synonyms. The only one of these I have not re-examined is T. feei Meissner<br />
ex Fée. Trypethelium phlyctaena Fée and T. quassiaecola Fée are synonymous with T. ochroleucum.<br />
Trypethelium scoria Fée is apparently a good species of Trypethlium s. lat.<br />
Bathelium degenerans (Vainio) R. C. Harris, comb. nov.<br />
Pseudopyrenula degenerans Vainio, J. Bot. 34: 292. 1896. Trypethelium degenerans (Vainio)<br />
Zahlbr., Cat. lich. univ. 1: 490. 1922. Type. DOMINICA. Laudat, 1700 ft, Elliot s.n. (BM, isotype).<br />
This species is very close to B. carolinianum but the pseudostromatal pigment reacts KOH+ red. The<br />
pigments need to be analyzed. The KOH reaction may be due to differing pigment concentrations. I have<br />
seen this in other species where a reaction may vary from yellow to red depending on concentration. For the<br />
present I am maintaining them as distinct as there is little overlap in distribution. Bathelium degenerans is not<br />
known from North America but is not uncommon in the Caribbean and Mexico, also known from Brazil, Costa<br />
Rica and Venezuela.<br />
