320 Journ. Hattori Bot. Lab. No. 43 1977 St. leptaleum NYL. Typus: Tasmania, no exact locality stated, on granitic rocks, leg. ?, ex herb. HOOK. F. (H-NYL, no. 39978, holotypus). St. corticatulum [subsp.]* detergens NYL. Typus: New Zealand, South Island, Otago, on rock, leg. ?, ex herb. JONES (H-NYL, no. 40025, holotypus). St. ramulosum var. compressum BAB. Typus: New Zealand, North Island, leg. COLENSO (date ?) (BM-BAB, holotypus; PC-MONT, isotypus), =St. fronduliferum LAMB. St. proximum var, compactius ZAHLBR. 2 collections cited, both from Chile, Juan Fernandez, Masafuera, leg. C. and I. SKOT- TSBERG, 1917. As lectotype we select that from Las Torres, no. 350 (ups, lectotypus, lectotypif: nov.; SGO, isolectotypus). The other specimen, from near Correspondencia, no. 343, is identical (ups). St. meyeri var. bornmiilleri B. STEIN Typus: Africa, Tanzania, Mt. Kilimanjaro, altit. 4000 m s. m., leg. H. MEYER, 1887. Holotypus (BRSL ?) not seen by us, but an isotype sent by B. STEIN studied in UPS-TH FR. St. haumanianum DUVIGN. Typus: Africa, Uganda, Ruwenzori, Mt. Stanley, altit. 4200 m s. m., leg. HAUMAN, 1932 (no. 931) (BRLU, holotypus). St. karisimbiense DUVIGN. Typus: Africa, Rwanda-Burundi, Karisimbi Volcano, altit. ca. 3600 m s. m., leg. HUMBERT, 192983 (BRLU, holotypus). St. penicillium DUVIGN. Typus: Africa, Uganda, Ruwenzori, Mt. Stanley, Campi Achupa, altit. 4000 m s. m., leg. HAUMAN, 1932 (no. 930) (BRLU, holotypus). St. mixtum var. tenellum MULL. ARG. Typus: Brazil, Slo Paulo State, near Apiahy, on rock, leg. J. I. PUIGGARI, 1879 (no. 151) (G-MOLL, holotypus). This specimen and the type of St. microcarpum MULL. ARC. were both collected near Apiahy by PUIGGARI, and both have the same collector's number (151). But according to the labels, that of St. microcarpum was collected in 1877, and that of St. mixtum var. tenellum in 1879. In spite of this apparent discrepancy in the dates, it seems possible that both may be portions of the same collection. St. proximum status ferruginascens MULL. ARG. Typus: Brazil, Minas GeraEs State, Ouro Preto, on weathered iron-mica schist, leg. H. SCHENCK, 1891 (no. 4523) (G-MULL, holotypus). St. implexum f. sorediosa VAIN. Typus: Brazil, Minas Gerais State, Serra do Frio, on rock, leg. E. A. VAINIO, 1885 (TUR-VAIN, holotypus, not seen by us, but the isotype material distributed in VAIN. Lich. Bras. Exs. no. 1188 studied 83 1931 acc. to the published description, but 1929 on the label.
I. MACKENZIE LAMB: A Conspectus of Stereocaulon St. ramulosum [subsp.]* roccelloides TH. FR. Typus: Hawaiian Islands, Oahu, near Honolulu, leg. N. J. ANDERSON (date ?) (UPS-TH FR, lectotypus; lectotypified by DODGE, 1929, p. 140). St. assimile NYL. Typus: RBunion (Bourbon) Island, Piton des Neiges, "a 1600 toises sur les rochers", leg. BORY DE SAINT-VINCENT (date ?) (PC, holotypus; H-NYL, no. 40077, isotypuss4). St. lecanoreum NYL. Typus: Colombia, near Antioquia, leg. D. JERVIS (date ?) (H-NYL, no. 40142, ex herb. HOOKER, holotypus). St. mixtum sorediatum NYL. Typus: Mexico, exact locality not stated, leg. GALEOTTI (date ?) (no. 6921) (H-NYL or PC ? Not seen by us). VAINIO, who apparently saw the type material, stated it to be synonymous with St. peladense VAIN. (=St. stricturn TH. FR.) (VAINIO, 1926). St. ramuIosum f. compressum NYL. Typus: "In America aequinoctiali", locality not stated, leg. BONPLAND (PC, not seen by us). NYLANDER'S description leaves no doubt as to its identity with St. stricturn var. cornpressurn (NYL.) LAMB. Not to be confused with St. ramulosum var. cornpressurn BAB. (=St. fionduliferurn LAMB). APPENDIX 2 A. Doubtful taxa St. botryosum subsp. islandicum DUVIGN. Biol. Jaarb. "Dodonaea", 8: 160 (1941). Typus: Iceland, Thingvellir, on lava among mosses, leg. VAN OYE, 1938 (no. 5) (formerly in BRLU, destroyed in World War 11, acc. to P. DUVIGNEAUD, personal comrnun.). According to DUVIGNEAUD'S description, morphologically similar to St. botryosum ACH. em. FREY but differing in its chemical constituents as shown by the form of the crystals produced in GE solution after extraction with acetone. Since the substance present was not characterized chemically, the identity of the taxon remains dubious. St. confluens ff. typica, gracilius, ramosa, fastigiata DUVIGN. Lejeunia, MCm. no. 14: 84 (1956) (all nomina nuda). No material seen by us; from DUVIGNEAUD'S illustrations most of them would appear to refer to St. vesuvianum PERS. (var. vesuvianum). In any case they are to be ignored as nomina nuda. St. coralligerum MEYER Nebenstunden meiner Beschaefftigungen im Gebiete der Manzenkunde, Erster Theil: 156 (1825). Material mentioned from Chile (leg. CHAMISSO) and Brazil (leg. BEYRICH). Very incompletely described. There is a specimen in UPS-TH FR labelled "Stereocaulon coralligerum Called lectotype specimen in LAMB, 1951, p. 528.
