278 Journ. Hattori Bot. Lab. No. 43 1977 GROENHART, who died in 1965, distinguished St. procerum as a new species and left isotype material and drawings with the present author. 93. Stereocaulon togashii LAMB (n. sp.) Diagn.: Statura et habitu omnino ut in St. massartiano HUE: pseudopodetia stipatocaespitosa aut forsan partim decumbentia, ad 6.5 cm alta, simplicia aut parum ramosa, glabra, pr. max. p. denudata, sorediis destituta, phyllocladiis divaricatis, coralloideis, ramosis, cephalodiis sacculatis, scrobiculato-corrugatis, intus laxe hyphosis, apotheciis vulgo singulatim in apicibus ramulorum lateralium prolatis, parvis, convexo-immarginatis; hypothecium incoloratum; hymenium (loo-) 130-150 p altum; sporae vermiformes, 7-12-septatae, longit. 75-120 p, crassit. 3.54.5 p. Thallus atranorinum, acidum lobaricum et acidum porphyrilicum geret (phyllocladiis PD leviter flavescentibus). - Materiis chimicis necnon distributione geographica (himalayensi) a St. massartiano diversum. Typus: Sikkim, Puleg-chu, altit. 2100 m s. m., leg. M. TOGASHI, 1960 (no. 6072) (FH, holotypus; ASAH, isotypus). Mat. chim.: atranorin, lobaric acid, porphyrilic acid. Distrib.: Himalayan region; N. India, Nepal, Sikkim, Bhutan). Remarks: morphological and microscopic characters are in full agreement with St. massartianum HUE, but the presence of lobaric and porphyrilic acids instead of stictic acid, combined with the distinctly separated pattern of distribution, surely entitles this taxon to the rank of a separate species. Cephalodial algae Scytonema in all specimens examined; cephalodial cortex 2540 p thick, gelatinized, colorless to sordid yellowish, clear, palisadic, with vertically parallel, oblong lurnina 1.0-1.5 p wide, also intermixed a number of larger, oval to isodiametric lumina 34 p in diameter. Pycnidia forming minute, dark brown, semiglobose swellings 0.10-0.15 mrn diarn. at apices of pseudopodetia; conidia filiform, curved, 9-lox ca. 0.5 LA. Subsect. B. Aciculisporae Du RIETZ ex LAMB 94.

I, fig. 1, PI. 11, fig. 6; 1976, fig. 1 (cephalodium). Mat. chim.: atranorin, perlatolic acid, often anziaic acid, occasionally possibly glomelliferic and stenosporic acids as accessory compounds, 2 unidentified substances. HUNECK and FOLLMANN (1967) reported atranorin only in a Chilean specimen; probably a deficient phase. CAMFSIE (1968) reported atranorin, anziaic acid and a hitherto unknown dimethyl ether of anziaic acid in New Zealand material. A mixture of unidentified tetrahydroxy fatty acids, in addition to atranorin and perlatolic acid, was reported in specimens from Jamaica, New Zealand, Argentina and Costa Rica by Fox and HUNECK (1970) and Fox, FOLLMANN and HUNECK (1971). DUVIGNEAUD (1942, 1956) had stated the chemical constituents of St. ramulosum and several other Stereocaulon species to be atranorin, divaricatic acid, and a chemically uncharacterized substance to which he gave the name "ramulosine" (not to be confused with the compound ramulosin produced by Pestalotia (Fungi Irnperfecti) and described by HESSELTINE, BENJAMIN, BRADLE and HENDERSHOT, 1963). The alleged presence of divaricatic acid in St. ramuIosum has not been confirmed by subsequent investigations. Dr. TH. ESSLINGER (Duke Univ.) investigated the chemical constitution of the pseudopodetia and the apothecia separately by thin-layer chromatography in material of St. ramulosum from Jamaica and New Zealand. Perlatolic acid, with traces of 2 unidentified substances, was found in both apothecia and pseudopodetia, but atranorin was present only in the latter (ESSLINGER, personal commun.). This investigation was suggested by the fact that in another 64 DICKSON, Hortus Siccus Britannicus Fasc. XI (1796) no. 24, named Lichen paschalis, in BM is a mixture of St. ramulosum and an indeterminable species, probably St. alpinum LAUR. NO locality is given on the label. 66 This is probably not a true exsiccat, as no fully printed labels were issued, most of the data being handwritten. The illustration of "Stereocaulon ramulosum" in YASUDA, 1925, PI. XIII, fig. 1 is of St. sorediiferum HUE.
