Two new species of Lejeunea Lib. (Hepaticae: Lejeuneaceae) from Sikkim,India

Abstract

Two new species of Lejeunea Lib., L. kashyapii sp. nov. and L. mehrana sp. nov. are described from Sikkim, India. The former is characterized by sub-orbicular leaves; first tooth of leaf lobule, 1–3 cells long 1–2 cells wide at base; reniform underleaves slightly wider than long; monoicous sexuality; 2–3-paired male bracts; obcordate perianth with 4–5 smooth keels (2 lateral, auriculate; 2 ventral; 0–1 dorsal, indistinct). Whereas, the latter is characterized by oblong – ovate leaves; lobule 1/6–1/5 as long as lobe; distant – contiguous underleaves with 1–3 teeth on each lobe; dioicous (?) sexuality; 2–4-paired male bracts and 1–2 male bracteoles present near the base of androecia. A key to the Indian species of the genus are provided.     

Naphtho‐γ‐pyrones from Endophyte Aspergillus niger Occurring in the Liverwort Heteroscyphus tener (Steph.) Schiffn.

Bioactivity‐guided fractionation of the cytotoxic extract of Aspergillus niger, an endophytic fungus from the Chinese liverwort Heteroscyphus tener (Steph .) Schiffn ., afforded five new naphtho‐γ‐pyrones, rubrofusarin‐6‐O‐α‐D ‐ribofuranoside ( 1 ), (R)‐10‐(3‐succinimidyl)‐TMC‐256A1 ( 2 ), asperpyrone E ( 3 ), isoaurasperone A ( 4 ), and isoaurasperone F ( 5 ), as well as four known ones, dianhydroaurasperone C ( 6 ), aurasperone D ( 7 ), asperpyrone D ( 8 ), and asperpyrone A ( 9 ), together with a cytotoxic cyclic pentapeptide, malformin A₁ ( 10 ). Their structures were determined by extensive spectroscopic analysis. The absolute configurations of dimeric naphtho‐γ‐pyrones 3 – 9 were also determined by analysis of their respective CD spectra.     

Hilpertia tibetica J.Kou,X.-M.Shao & C.Feng (Pottiaceae), a new species from Tibet,China

A new species, Hilpertia tibetica J.Kou, X.-M.Shao & C.Feng from Chara Mountain, Dagzê County, Tibet, China, is described and illustrated. It is similar to Hilpertia velenovskyi (Schiffn.) R.H.Zander, but its erect to erecto-patent leaves when moist, the quadrate to short-rectangular, strongly bulging ventral epidermal cells forming a bulliform ridge on the adaxial surface of the costa, not or slightly thickened superficial abaxial laminal cell walls, the annulus consisting of 2–3 rows of rectangular to elongate cells, much smaller spores and yellow-orange laminal KOH colour reaction, readily separate it from the latter. This new species is compared with closely related species and its ecology is discussed.     

Secondary Metabolites from Aspergillus fumigatus,an Endophytic Fungus from the Liverwort Heteroscyphus tener (Steph.) Schiffn.

Three new metabolites, asperfumigatin ( 1 ), isochaetominine ( 10 ), and 8′‐O‐methylasterric acid ( 21 ), together with nineteen known compounds, were obtained from the culture of Aspergillus fumigatus, an endophytic fungus from the Chinese liverwort Heteroscyphus tener (Steph.) Schiffn. Their structures were established by extensive analysis of the spectroscopic data. The absolute configurations of 1 and 10 were determined by analysis of their respective CD spectra. Cytotoxicity of these isolates against four human cancer cell lines was also determined.     

Miscellanea hepaticologica 201-210

Abstract

201. Calycularia crispula Mitt. new to Mexico and the whole America. It is the first record outside Asia. 202. A type study of Fimbriaria nana Lindenb. revealed that it is synonymous with Athalamia hyalina (Sommerf.) Hatt. 203. Fossombroniaceae Hazsl. 1885 has to replace Codoniaceae Klinggr.1858 nom. illeg., because Codonia Dum. 1822 is illegitimate. 204. Herzogobryumaterrimum (Steph.) c. n. (≡ Cephalozia aterrima Steph.) has to replace H. filarium Grolle 1975. 205. Korrnickia Steph. 1917 is regarded as a synonym of Symphyogyna Nees et Mont. 1836 and K. cylindrica Steph. 1917 is placed in synonymy of S. mexicana Steph. 1909.206. The detection of the perianth of Lophocolea spectabilis Steph. (≡ Heteroscyphus arnellii Fulf.) necessitates a transfer as Leptoscyphus spectabilis (Steph.) c. n. 207. All records of Preissia Corda from Latin America are rejected. P. barbata Herz. 1921 is referred to as syn. nov. of Marchantia chenopoda L. 1753. 208. Riccia crustata Trab. was validly published in 1916 already, but has been generally overlooked hitherto. 209. Symphyogyna brasiliensis. Nees et Mont. is widespread in the Neotropics and Africa. Several African names are treated as synonyms. 210. The monotypic genus Wiesnerella Schiffn. is newly recorded from New Guinea and the Mascarenes. The Mascarene record is the first one outside Asia.     

Frullania larjiana (Jungermanniopsida: Frullaniaceae), a new species from India

A new species of Cheilolejeunea (Spruce) Schiffn. from Panama

Abstract

Cheilolejeunea (subgen. Strepsilejeunea) norisiae G. Dauphin & Gradst. sp. nov. is described and illustrated. The new species differs from other members of the genus Cheilolejeunea by the laciniate leaf margins and the large pre-apical tooth.     

A morphological revision of the genus Herbertus S.Gray (Herbertaceae,Marchantiophyta) in Africa,including the East African islands

Abstract

The genus Herbertus S.Gray in Africa and the East African islands is revised. The division of the genus into two broad species complexes centred on H. dicranus (Tayl.ex Gottsche et al.) Trev. and H. juniperoideus (Sw.) Grolle is confirmed. H. capensis (Steph.) Sim, H. capillaris (Steph.) H. doggeltianus (Steph.) Demaret, H. lobatus (Steph.) Demaret, H. mascarenicus (Steph.) S.Arn., H. mollis (Steph.) Dusén, H. stuhlmannii (Steph.) Demaret and Schisma kilimandjarense Steph. are synonymous with H. dicranus. H. grossevittatus (Steph.) S.Arn. ex Grolle is synonymous with H. juniperoideus. Three new species are described: H. spicatus N.G.Hodgetts sp. nov., which is related to H. juniperoideus and appears close to the neotropical H. pensilis, with long, narrow leaf lobe apices and a sheathing leaf base; H. mauritianus N.G.Hodgetts sp. nov., also related to H. juniperoideus, has fewer basal slime papillae and the vitta bifurcating lower down; and H. pocsii N.G.Hodgetts sp. nov., which is related to H. dicranus but has setaceous leaf lobe apices composed of long, narrow cells. The relationships of the taxa and patterns of distribution, taking account of recent molecular work, are discussed.     

Miscellanea hepaticologica (71-80)

Abstract

(71) Cephalozia lunulifolia (Dum. 1831) Dum. 1835—lectotype (nov.): Mougeot & Nestler 432/e, c. per., BR—has to replace C. media Lindb. 1881. (72) Kymatocalyx stoloniferus Herz. 1950, syn.nov.: Solenostoma apertum Schiffn. & S. Arn. 1964. Because of the structure of its seta Kymatocalyx Herz. is newly placed within Cephaloziellaceae. (73) Lophozia capitata (Hook.) Boulay 1904 has to replace L. capitata (Hook.) K. Müll. 1950. (74) All Scandinavian records of Lophozia latifolia Schust. are rejected. (75) Notoscyphus macroscyphus Schiffn., N. fluviorum Schiffn. and N. paulensis Schiffn., all in Schiffner & S. Arnell (1964), are newly placed in synonymy of Lophocolea aquatica Herz. 1950. Notoscyphus Mitt s.str. remains palaeotropic in distribution. (76) Plagiochila corniculata (Dum.) Dum. validly dating as a species from 1831 has to replace P. tridenticulata Dum. validly dating as a species from 1835. (77) P. Punctata Tayl. 1846, syn.nov.: P. pitardii Steph. 1921.(78) P. spinulosa (Dicks. 1790) Dum., syn.nov.: P. maderensis Gottsche in Steph. 1904, and P. castellonis Gottsche in Steph. 1918. (79) Critical notes on Plagiochila sect. Plagiochila in Europe. List of names to be considered, with their types. Lectotype (nov.) of Jungermannia asplenioides L.: specimen in OXF corresponding with Dillenius. Hist. Musc. 482, tab. 69, fig. 5, Oxford, 1747. The large European taxon of section Plagiochila has to bear the name P. aspleniodes (L. emend. Tayl.) Dum. (= P. major (Nees) S. Arn., nomillegit.). The smaller plants of section Plagiochila in Europe perhaps are heterogeneous and may be called provisionally P. porelloides (Torrey ex Nees) Lindenb. s.amplo (= P. asplenioides sensu S. Arn., non (L.) Dum.). (80) Attention is called to four old Porella combinations by Pfeiffer (1855).
