324 Journ. Hattori Bot. Lab. No. 43 to designate St. evolutoides (MAGN.) FREY (=St. saxatile MAGN.). St. paschale [f.] c. subcrustosum FR. Lichenographia Europaea Reformata: 202, 203 (1831). No type designated. The description runs: "c. subcrustosum, rarnuloso-inaequabile, apotheciis maximis. . . primo obtutu P. subfuscam terrestrem refert". No material with this name could be found in ups. MAGNUSON (1926, p. 49) treated it as an "accidental form" of St. paschale, but the description of "apotheciis maximis" does not accord well with that species; St. rivulorum MAGN. would be more likely. A doubtful taxon. St. paschale f. velutinum FREY Rabenhorsts Krypt.-F1. 9, Abt. IV, 1. Halfte: 152 (1932). Typus: Poland or Czechoslovakia (former W. Schlesien), Heinersdorf, leg. FLOTOW (date?) (B, destroyed in World War I1 and not seen by us). From FREY'S description and illustration (PI. 111, fig. 3) it seems to agree with either St. alpinurn var. erectum FREY or St. grande (MAGN.) MAGN., but cannot be identified with certainty. St. proximum f. sorediata NYL. Synopsis Methodica Lichenum, 1 (2): 237 (1860). - Stereocaulon sorediatum (NYL.) VAIN. Dansk Bot. Ark. 4 (1 1): 7 (1926). No type specimen is cited in NYLANDER'S original description, and VAINIO mentions no original material. Being impossible to typify, the taxon is a doubtful one, but possibly refers to St. meyeri B. STEIN. St. rivulorum f. nana CENGIA SAMBO Nuovo Giorn. Bot. Ital. n. s. 40: 284 (1933). Typus: Italy, Piedmont, Passo Piccolo San Bernardo, leg. ?, date ?. No specimen bearing this name could be found in CENGIA SAMBO'S herbarium (FI), which contains only one specimen labelled "Stereocaulon rivulorum", from Passo San Bernardo, Lake Verney, and published as such by CENGIA SAMBO up. cit. p. 287; it is St. alpinum LAUR. This misidentification makes it seem very likely that the f. nana also does not belong to St. rivulorum MAGN., a species which we have not seen from Italy. St. solutum LAMB ex LYNGE, Skr. om Svalbard og Ishavet, no. 76: 50 (1939) (nomen nudum). This taxon, never validly published, was based on a specimen from Jan Mayen, Fishburn Valley, leg. R. S. RUSSELL, 1938 (no. 510 pr. p.) in BM. It is a sorediate species with some resemblance to St. capitellatum MAGN. and St. coniophyllum LAMB. Chromatography revealed only atranorin and a weak trace of some unidentified substance. Its identity is doubtful. St. spissum f. granuliferum FREY Rabenhorsts Krypt.-F1. 9, Abt. IV, 1. Halfte: 141 (1932). - St. dactylophyllum f. granuliferum (FREY) GRUMM. Catalogus Lichenum Germaniae: 24 (1963). FREY'S statement on typification is unclear, but it would seem that he refers to a specimen from Germany, Harz, Lauterburg, in herb. ZSCHACKE. This specimen (in B) was destroyed in World War 11, and was not seen by us; its identity is uncertain. Flora, 58: 358 (1875). St. subintricans NYL.
I. MACKENZIE LAMB: A Conspectus of Stereocaulon 325 Typus: Finland, Hollola, Hayhto, on rock, leg. E. LANG (VAINIO), 1874 (H-NYL, no. 39967, holotypus). Obviously belongs to the paschale-saxatile group, but is peculiar in its copious fertility, with numerous minute apothecia, and its quite glabrous pseudopodetia. Phyllocladia PD-. We could not see any affinity with St. subcoralloides (NYL.) NYL., to which NYLANDER relates it. FREY also saw the type specimen, and gives some anatomical details (1932, p. 116). Although several specimens from Europe and N. America have been seen which correspond more or less to it, we cannot be sure of the identity, and prefer to consider St. subintricans as a doubtful species. St. tenuissimum DEL. ex NYL. Synopsis Methodica Lichenum, 1 (2): 242 (1860). Published by NYLANDER under St. coralloides FR., as "forma videtur sterilis transiens fere in Ster. Delisei. Cephalodia illius tenuissimi interdum cinereo-olivacea", from France, Dept. Calvados, St. Sever near Vire. The specimen not seen by us, and its identity doubtful. St. tomentosum f. jlabelliforme OHL. Schr. Konigl. ~hys.-bkon. Ges. Konigsberg, 11: 8 (1870). 3 localities in former E. Prussia (now Poland) mentioned (Oletzo, Angerburg, Neustadt), no holotype designated. We have not seen any of the type material,86 nor apparently did FREY, who from the description equates it with typical St. tomentosum (1932, p. 184). OHLERT describes it as flabellately expanded with the phyllocladia forming a continuous crust on the upper side, and the pseudopodetia glabrous on the underside. The latter feature does not conform to St. tomentosum, and the f. flabelliforme, until the type material is found, must be regarded as a doubtful taxon. St. tomentosum var. hercynicum FREY Rabenhorsts Krypt.-Fl. 9, Abt. IV, 1. Halfte: 187 (1932). Typus: Germany, Harz, Lautenberg in Lutter Valley, leg. ZSCHACKE (date?), destroyed with ZSCHACKE'S herbarium (B) in World War 11, and not seen by us. From FREY'S description it seems to be probably synonymous with St. tomentosum var. compactum FREY. St. tomentosum f. leptothamnium FREY Rabenhorsts Krypt.-FI. 9, Abt. IV, 1. Halfte: 185 (1932). Typus: Poland (formerly Schlesien), Hartau, probably near Katzengebirge, leg. FLOTOW (date?), destroyed with FLOTOW'S herbarium (B) in World War 11, and not seen by us. From FREY'S description it appears to be a non-taxonomic modification of St. tomentosum, but its status remains doubtful. St. tomentosum f. walamoense NYL. Synopsis Methodica Lichenum, 1 (2): 244 (1860). -St. tomentosum var. walamoCnse (Nn.) Nn. Lichenes Scandinaviae: 65 (1861). - Stereocaulon valamoCnse [sic] (NYL.) RAS. Meddeland. Soc. Fauna Fl. Fenn. 50: 39 (1925). -St. alpinum f. walamoCnse (NYL.) FREY, Rabenhorsts Krypt.-FI. 9, Abt. IV, 1. Halfte: 164 (1932). Typus: U.S.S.R., Karelia ladogensis, Valarno Island in Lake Ladoga, "supra terram nudam aridissimam", leg. W. NYLANDER, 1851 (H-NYL, no. 39952, holotypus; PC, isotypus). A very minute and poor specimen, resembling a much depauperated condition of St. s6 OHLERT'S herbarium is reputed to be at the University of Konigsberg (now Kaliningrad).
