LICHEN GENUS MICAREA IN EUROPE 203<br />
Map 28 Psilolechia clavulifera # 1950 onwards O Before 1950<br />
Sporacestra Massal. in Atti R. 1st. veneto Sci. Ill, 5: 264 (1860). Type species: Biatora prasina Tuck. &<br />
Mont, in Mont. (1857), non (Fr.) Trevisan (1856).<br />
Sporacestra was included as a synonym <strong>of</strong> Micarea by Vezda & Wirth (1976: 99) who confused <strong>the</strong> two<br />
quite separate applications <strong>of</strong> <strong>the</strong> name 'Biatora prasina' . The name Biatora prasina Tuck. & Mont, was<br />
introduced for a corticolous species from Venezuela with long acicular spores, and no reference was made<br />
to <strong>the</strong> 'prasina' <strong>of</strong> Fries. Similarly, Massalongo made no reference to Fries' name and his generic<br />
description (e.g. '.<br />
. . sporidii capillari aghiformi, lineari allungati . . .') clearly refers to <strong>the</strong> stated type<br />
species, ' Biatora prasina Mont., Tuck.'.<br />
The Venezuelan species was transferred to Bacidia de Not. by Zahlbruckner, but his use <strong>of</strong> <strong>the</strong> epi<strong>the</strong>t<br />
'prasina' is contrary to <strong>the</strong> present Code. From <strong>the</strong> descriptions <strong>of</strong> this species I believe it should be<br />
retained in Bacidia, pending fur<strong>the</strong>r study. The nomenclature and required new combination for <strong>the</strong><br />
species is as follows:<br />
Bacidia prasinata (Tuck.) Coppins, comb. nov. - Biatora prasinata Tuck, in Syn. N. Am. Lich 2: 41 (1888);<br />
nom. nov. - Bacidia prasina Tuck & Mont, in Mont, in Annls Sci. nat. IV, 8: 296 (1857), non (Fr.) Trevisan<br />
(1856). - Bacidia prasina Zahlbr., Cat. lich. univ. 4: 253 (1926); nom. illeg. (Art. 11). Type: Venezuela, on<br />
bark, Fendler (not seen).<br />
Index to exsiccatae<br />
I have attempted to examine at least one example <strong>of</strong> all European and North American material<br />
referable to Micarea and distributed in recognized exsiccatae (Lynge 1915-22, 1939; Sayre,<br />
1969). My preliminary list was compiled from Lynge {op. cit.), available schedae, major floras
