Phyllopsora breviuscula is pantropical, but in the West Indies only known<br />
from Wright’s material from Cuba and Duss’ material from Guadeloupe (not<br />
examined by me). The specimen from Saint Vincent reported by VAINIO (1896)<br />
belongs in P. chodatinica (Elliot 135, BM).<br />
Specimens examined: CUBA. Wright s.n. (H-NYL 20557, holotype, TLC not performed), Wright,<br />
Lich. Cub. 181 (B, BM, UPS).<br />
2. Phyllopsora buettneri (Müll. Arg.) Zahlbr.<br />
Catal. Lich. Univers. 4 (25): 396 (1926). <strong>–</strong> Psora buettneri Müll. Arg., Engler Bot. Jahrb. 15: 506<br />
(1893). <strong>–</strong> Type: TOGO (see SWINSCOW & KROG 1981). <strong>–</strong> Descriptions: TIMDAL & KROG (2001),<br />
TIMDAL (2008b), ELIX (2009).<br />
Chemistry: chemotype 1 (paleotropical): pannarin (major) and zeorin (major);<br />
chemotype 2 (neotropical): pannarin (major), phyllopsorin (major) and zeorin<br />
(major); chemotype 3 (neotropical): vicanicin (major), norvicanicin (trace to<br />
minor) and zeorin (major); chemotype 4 (paleotropical): dechloropannarin (major)<br />
and zeorin (major); chemotype 5 (Norfolk Island, ELIX 2006a, not examined by<br />
me): argopsin, norargopsin and zeorin.<br />
Notes: The species is recognized by the large, elongated, pruinose, lacinulate<br />
squamules always containing zeorin and in addition pannarin (plus phyllopsorin in<br />
the Neotropics) or the related compounds argopsin (plus norargopsin),<br />
dechloropannarin or vicanicin. Both neotropical chemotypes occur in the West<br />
Indies. If regarded as distinct species, they should be named P. munda (Malme)<br />
Zahlbr. (chemotype 2) and P. melanoglauca Zahlbr. (chemotype 3). There are no<br />
known morphological or anatomical differences between the five chemotypes of<br />
P. buettneri, however. The holotype of P. munda (Brazil, Malme, Lich. Regnell<br />
617b, S) contains phyllopsorin (major), pannarin (submajor), and zeorin (minor),<br />
and an isotype of P. melanoglauca (Brazil, Schiffner s.n., BM) contains vicanicin<br />
and zeorin (both major).<br />
BRAKO's (1991) varieties and chemical strains of P. buettneri correspond to the<br />
following species and chemotypes in the present work: var. buettneri = P.<br />
buettneri chemotype 1; var. glauca (B. de Lesd.) Brako chemical strain I = P.<br />
porphyromelaena; strain II = P. chodatinica; strain III = P. porphyromelaena; var.<br />
munda (Malme) Brako = P. buettneri chemotype 2. See also P. hispaniolae for<br />
discussion.<br />
The species is pantropical. New to Haiti, Jamaica and Trinidad and Tobago.<br />
