Liparis indiraii spec. nova from India is close toL. alata A. Rich. andL. atropurpurea Lindl.     

Alternaria leaf spot of rose from India

Summary A new leaf spot of Rose incited by anAlternaria species has been described from India. The pathogen has been determined as a variety ofAlternaria tenuis Auct. on the basis of morphology and host-specificity and is designated asA. tenuis var.rosicola. The disease is of great economic importance, found to infect a large number of superior and cultivated varieties of Rose in nature.Part of the author's Ph. D. (Agri.) thesis, Poona varsity, India, 1964.

Summary The symptoms of leaf blight of bajra (Pennisetum typhoides Stapf.) from India, its cause which has been identified asCurvularia penniseti (Mitra)Boedijn var.poonensis n. var. together with the morphology and host range of the fungus etc. have been given.Part of the work submitted by ShriP. L. Patil for M. Sc. (Agric.), University of Poona, under the guidance of Dr.N. B. Kulkarni.The authors express their sincere thanks to Prof.M. Sulaiman for providing necessary facilities for this work.     

On the morphology and life-history of a form of gloeocapsa showing some new stages

Summary A new variety of Gloeocapsa, G. crepidinum Thuret var. ghazipurensis n. var., has been isolated from enrichment cultures of paddy field soils of Ghazipur, Uttar Pradesh, India. The alga has been studied in detail. The form is especially interesting since it showed certain growth-stages recorded in G. alpina Naeg.The authors are thankful to Rev. Dr. H. Santapau for rendering the Latin diagnosis of the new variety.     

Initiation of the dikaryon in Claviceps microcephala (Wallr.) Tul.

Summary An account of the nuclear behaviour in the initiation of the dikaryon inClaviceps microcephala (Wallr.)Tul. inciting the ergot of bajri in India is given. The pattern follows closely the mode of dikaryotization reported byKillian (1919) forClaviceps purpurea (Fr.)Tul., characterised by functional antheridium, absence of trichogyne, the Claussentype of nuclear fusion and hook-formation.     

Pseudoeurotium globosum n. sp., a new ascomycete from Indian soils

Summary The namePseudoeurotium globosum Rai andTewari n. sp. has been given to a fungus isolated from soil collected from the banks of a stream in village Harchandpur, District Rae Bareli, (U.P.) India. This form is distinguished from any other described so far in this genus, in having multisporous asci with large globose ascospores. P.globosum n. sp. inhabits a specialised habitat, and this along with the fact that it was isolated only byWarcup's Soil-plate Method, makes it an ecologically interesting form.     

Humesiella corallicola n.g., n.sp., a cyclopoid copepod associated with coral on the South East Coast of India

Humesiella corallicola n.g., n.sp., a lichomolgid copepod associated with the hard coral Hypnophora sp. is described from the South East Coast of India. Genus Humesiella nov. is close to Lichomolgus Thorell, Nasomolgus Sewell, Lichomolgides Gotto and Epimolgus Bocquet & Stock, in possessing a two-segmented fourth endopod with 2 terminal spines. However, it differs from all the known lichomolgid genera in having a massive appendage-like posterior basal lobe on the second maxilla.     

The oldest Jurassic cyathophorid coral (Scleractinia) from siliciclastic environments of the Kachchh Basin, western India

Cyathophora Michelin, 1843, hitherto well known from the Upper Jurassic and Cretaceous, has been found in the Middle Jurassic (Bajocian) of the Kachchh Basin, western India. Eleven specimens ofCyathophora bourgueti (Defrance, 1826) from the Babia Cliff Sandstone member of the Kaladongar Formation, exposed along the northern scarp of the Kala Dongar, Pachchham Island, Kachchh, are described and illustrated as the earliest Jurassic record of the family CyathophoridaeVaughan & Wells, 1943. It is suggested that the monospecific occurrence ofCyathophora bourgueti was controlled by salinity.      

Amorphophallus nicolsonianus (Araceae), a new species from India

Amorphophallus nicolsonianus species nova, with cylindrical or napiform corms, is the only representative of the sect.Rapyogkos in India. All the other hitherto known species of this region have globose or depressed globose corms. The new species is related to some Indochinese species and toA. hildebrandtii ( Engl.)Engl. & Gehrm. from Madagascar.     

Fungi causing plant diseases at jabalpur (madhya pradesh)-IX

Summary The present paper describes 6 foliicolous fungi from Jabalpur (India). These includeAsterina lawsoniae Syd. on leaves ofLawsonia alba, Diplocarpon rosae Wolf. onRosa sp.,Cercospora jujubae Chowdhury onZizyphus jujuba andCercospora subsessilis Henn. &Nym. onAzadirachta indica, new fungus records for Madhya Pradesh;Asterostomella strophanti Henn. on leaves ofFlacourtia ramontchii, a new fungus for the country andCorynespora cassiicola (Berk. &Curt.)Wei. onClerodendron inerme, a new host record.     

On two fresh water red algae from Dehradun

Summary The present communication deals with morphological features of a new fresh water species of the genus Acrochaetium Naëg. (A. sarmaii sp. nov.). The occurrence of Compsopogon iyengarii is also recorded for the first time from a locality in North India.     

Sporotrichum carthusio-viride rai & Mukerji,a new species from Indian soils

Summary A new species,Sporotrichum carthusio-viride Rai &Mukerji, isolated from a soil sample collected from Kukrail area, Lucknow, India is described. It differs from other species in its colony colour and conidial measurements. It also forms yeast-like colonies on Wort's agar which produce terminal and inter-calary chlamydospores and budding cells.     

Atherurus karnuliensis Lydekker, 1886, a Pleistocene brush-tailed porcupine from India, China and Vietnam

Pleistocene porcupine remains from China allocated toAtherurus sp.,Atherurus cf.macrourus andTrichys cf.fasciculata, and from Vietnam toAtherurus macrourus have been studied. These fossils have been compared with the type material of the PleistoceneA. karnuliensis Lydekker, 1886 from India and with the extant speciesA. macrourus (Linnaeus, 1758) andTrichys fasciculata (Shaw, 1801). As a result, all fossil specimens studied are allocated toA. karnuliensis.     

Some interesting morphological features in Tolypothrix spp.

Summary Tolypothrix magna Bharadwaja is reported for the first time from India while Tolypothrix limbata Thuret is recorded new to North India. In both species, geminate and single pseudo-branches have been sometimes observed to produce immediately pseudobranches of the second order. Thus, three or four pseudobranches may be seen arising from the same position of the parent filament. Such single pseudobranches are also associated always with unipored heterocysts and may be formed on one or on both sides of the filament.

Zusammenfassung Tolypothrix magna Bharadwaja wird erstmalig von Indien gemeldet, während Tolypothrix limbata Thuret als eine neue Art in Nordindien aufgezeichnet wird. In beiden Arten wurde beobachtet, dass paarweise and einzelne Scheinverzweigungen manchmal eine zweite Art der Scheinverzweigungen sofort hervorbringen. Auf these Weise können drei oder vier Scheinverzweigungen, entstehend von der gleichen Stelle des Hauptfadens, sehen werden. Einzelne Scheinzweige sind immer mit Einzigporeheterocysten vergesellschaftet and können an der einen oder an beiden Seiten von dem Faden gebildet werden.

     

Molecular identification of <Emphasis Type="Italic">Staphylococcus xylosus</Emphasis> MAK2, a new α-<Emphasis Type="SmallCaps">l</Emphasis>-rhamnosidase producer

A bacterial strain, MAK-2, was isolated as a producer of α-l-rhamnosidase from a soil sample of Dehradoon, India. The strain was identified based on morphology, physiological tests and 16S rDNA analysis. The phylogenetic analysis based on the 16S rDNA sequence, identified the isolate as Staphylococcus xylosus, a non-pathogenic member of CNS (coagulase-negative staphylococci) family. The strain was capable of producing α-l-rhamnosidase by hydrolysing flavonoids thus confirming potential application in the citrus-processing industry.     

Assimilation of ethylenediamine as nitrogen source by the cyanobiont Nostoc ANTH

Nostoc ANTH metabolizes ethylenediamine (EDA) as sole nitrogen source but not as a carbon source. EDA is assimilated by the glutamine synthetase-glutamate synthase pathway. EDA represses heterocyst formation and nitrogenase activity but this is reversed by l-methionine-dl-sulphoximine.The authors are with the Department of Microbiology, Barkatullah University, Bhopal 462 026, India
