Pteromalidae etEulophidae nouveaux d'Europe (Hym., Chalcidoidea)

Summary In the present paper the Author has described three new genera ofPteromalidae, two new species of the genusEnaysma Del. and one of the genusEpilampsis Del. (Euloph. Entedontinae). The first Pteromalid genus,Stenoselma, is closely related to the well knownAnisopteromalus Ruschka; the second new genus,Apelioma, has been proposed forDinotiscus (Dinotus) pteromalinus Thomson; the third,Aggelma, has been described for the new speciesabdominalis, collected in Central Europe onPinus montana. The other new species ofEntedontinae has been bred from leaf-miners (Lepidoptera).      

The Miocene Architectonicidae (Gastropoda) of Chile

Three new species of Architectonicidae Heliacinae,Heliacus (Torinista) chonos, Heliacus (Grandeliacus) antu andSolatisonax bieleri, are described. These include the first reports ofGrandeliacus andSolatisonax from Chile.Solarium australe Philippi, 1887 is an earlier name forHeliacus (Torinista) bahamondei Frassinetti & Covacevich, 1981, but is a junior homonym ofS. australe Philippi, 1849. Type material and new specimens of the five previously described architectonicid species from Chile are described and figured for comparison. Together with other gastropod taxa from the same deposits, Architectonicidae provide evidence for tropical to subtropical water temperatures in central Chile during the early Miocene.     

Some foliicolous ectoparasites and associated fungi from Jabalpur (M.P.) — I

Summary The present paper describes nine ectoparasitic foliicolous fungi from Jabalpur (M.P.) India. These include four new species viz.Asterina woodfordiae Sahni onWoodfordia fruticosa (L.)Kurz.,Schiffnerula fici Sahni, onFicus infectoria Roxb.,Sarcihella fumosus Sahni onAegle marmelos Corr. andSarcinella odinae Sahni onOdina wodier Roxb.,Acremoniella sarcinellae Pat. &Har.,Fumago vagans Pers.,Stigmella palawanensis Syd. andSchiffnerula cassiae are new fungus records for this country.Mitteriella zizyphina Syd. has been recorded onZizyphus xylopyra Willd., for the first time from this state.Z. xylopyra is a new host record forM. zizyphina.     

Zwei neue Heliotropium-Arten aus Afghanistan

Summary Two new species ofHeliotropium sect.Catimas DC. from the desert Registan in south-eastern Afghanistan are described, one of which,H. arenicolum Rech. f. et H.Riedl, is very closely related toH. Rechingeri H.Riedl (1967) and different from it only in the colour of the stems and the longer basal part of the style. The other one,H. leucocladum H.Riedl, belongs to a very natural group of xerophytic and halophytic species includingH. digynum (Forssk.)Aschers.,H. eremobium Bge.,H. Aucheri DC.,H. halame Boiss. etBuhse,H. Popovii H.Riedl andH. carmanicum Bge. Adaptations to the extremely dry habitat are discussed.     

A new scolenaspidid (Osteostraci, Vertebrata) from the Lower Devonian of Podolia, Ukraine

Anew osteostracan genus and species,Victoraspis longicornualis n. gen., n. sp., is described based on material from Rakovets’, present day Ukraine. This new taxon shares characters with the two generaStensiopelta Denison, 1951 andZychaspis Janvier, 1985. A phylogenetic analysis supports the position ofVictoraspis as the sister group to a monophyleticStensiopelta, while the interrelationships of the various species ofZychaspis are poorly resolved. A morphometric analysis is carried out in an attempt to further resolve the taxonomic affinity. This analysis groups all examinedZychaspis species closely together, and further supports the establishment ofVictoraspis as separate genus.      

Ascomycetes on Celastrus paniculata Willd

Summary The paper deals with Ascomycetes fungi onCelastrus paniculata Willd,Hysterium celastrina Tilak andBagnisiella celastrina Tilak are new species described whileEutypella stellulata (Fr)Sacc. forms a new host record.     

Tillandsia carminea — eine interessante neue Bromeliacee aus dem Orgelgebirge bei Rio de Janeiro (Brasilien)

Tillandsia carminea is a new, morphologically and ecologically distinct species, related toT. stricta Solander, which occurs in the Serra dos Orgaos near Teresopolis, Brazil. It has been taken forT. rosea Lindley, but new investigations have shown thatT. rosea is a synonym toT. stricta and thatT. carminea is a good and distinct species.

Delineations of forest fungi

Summary Several forest fungi, primarily species that occur in Mississippi, are discussed, and three species are described as new. These includeBotryobasidium (subgenusBrevibasidium)croceum Lentz,Tharoopama mississippiensis Lentz, andHarpographium zonatum Lentz.Dactylium leptosporum (Sacc.)Lentz is recognized as a distinct species, rather than as a subspecies ofD. dendroides Fr. Allescheriella crocea (Mont.)Hughes,D. leptosporum andMelanographium cookei M. B. Ellis are reported from Mississippi for the first time. Attention is called to the fact thatM. citri (Fragoso &Ciferri)M. B. Ellis apparently has not previously been reported from the United States, although a specimen from Florida is in the National Fungus Collections.B. croceum evidently represents the basidiophorous stage ofA. crocea.     

The species ofEretmocerus Haldeman, 1850 [Hymenoptera: Aphelinidae] from India

Nutritional studies on species and mutants of Lepista,Cantharellus, Pleurotus and Volvariella

The purpose of this study is to determine the ability of select Agaricales species to utilize various sources of carbon, nitrogen, vitamins, and growth hormones. Fungi selected for the studies include:Cantharellus clavatus Fries,C. cibarius Fries,Lepista nuda (Bull. ex. Fries)Cooke,Pleurotus ostreatus (Jacq. ex. Fries)Kummer, andVolvariella volvacea (Bull. ex. Fries)Singer. Three strains ofC. cibarius and one mutant ofV. volvacea (V135), V134, were employed to determine if nutritional requirement differences occurred. One species,V. volvacea, is grown commercially as a cottage industry in the Orient (Alicbusan &Ela, 1961) while the other species currently have no commercial value. All species studied possess pleasing flavors and have potential use in the mushroom production industry.A literature compilation of the nutritional regulation of basidiocarp formation and vegetative growth of Agaricales was made with specific mention to the named species (Volz &Beneke, 1969). Recent nutritional studies with one or more of the specific species include those byYusef &Allam (1967), andEger (1970).     

Bemerkungen zu einigenStipagrostis-Arten (Gramineae) aus Afrika und Arabien

Summary A new species from Egypt (Sinai) and Arabia is described asStipagrostis multinerva H.Scholz. Stipagrostis arabiaefelicis Bor 1967 is a synonym ofSt. drarii (V.Täckholm)de Winter 1963 (Aristida drarii V.Täckholm 1941). The taxonomic status ofStipagrostis foexiana (Maire etWilczek)de Winter (Aristida obtusa subsp.pubescens Andreánszky) in North and South Africa is discussed. Furthermore some new data on taxonomy and distribution of the following species are recorded:Stipagrostis acutiflora subsp.algeriensis (Henrard) comb, nov. et stat. nov.,St. ciliata (Desf.)de Winter,St. lanata (Forsk.)de Winter,St. libyca (H.Scholz) comb, nov.,St. papposa (Trin. etRupr.)de Winter,St. raddiana (Savi)de Winter,St. shawii (H.Soholz) comb, nov., andSt. sokotrana (Vierhapper)de Winter.      

Interspecific hybridizations among species of theElymus semicostatus andElymus tibeticus groups (Poaceae)

Interspecific hybridizations were made between species of theE. semicostatus group, viz.,E. semicostatus (Nees exSteud.)Meld.,E. validus (Meld.)B. Salomon,E. abolinii (Drob.)Tzvel., andE. fedtschenkoi Tzvel., and species of theE. tibeticus group, viz.,E. pendulinus (Nevski)Tzvel.,E. tibeticus (Meld.)Singh,E. shandongensis B. Salomon, andE. gmelinii (Ledeb.)Tzvel., as well as among species within theE. tibeticus group. All species are tetraploid (2n = 4x = 28) and possess SY genomes. Meiotic pairing data from 24 hybrids involving 17 interspecific combinations are presented. The average number of chiasmata per cell ranged from 17.91 to 26.20 in hybrids within theE. tibeticus group, compared with 7.26 to 22.04 in hybrids between the two species groups. Despite the extensive collection of cytological data, there was no definite evidence for confirming or disproving the separate existence of the two groups.     

Beiträge zur Kenntnis der europäischen Raupenfliegen (Dipt. Tachinidae)

Summary In this revision of the European species of the genusMyxexoristops t. t. (parasites of sawflies) six species, including a new one (abietis n. sp., parasite ofCephalcia), are described by their distinguishing characters. Separate keys for the determination of males and females are given. For five species, hosts are recorded on the basis of bred material examined by the author himself.Zenillia nox hall, described from Japan is identical to the European speciesM. stolida stein (nov. syn.).      

Some helicosporae from Hyderabad-II

Summary In this communication four species each ofHelicomyces Linder andHelicosporium Nees are reported.Helicomyces hyderabadense, Helicosporium indicum andH. nizamabadense are reported as new species.Helicomyces fuscopes Linder,H. lilliputeus Moore andHelicosporium Neesii Moore are first records to India.     

Desmarestia antarctica (Desmarestiales,Phaeophyceae), a new ligulate Antarctic species with an endophytic gametophyte

Desmarestia antarctica Moe & Silva, a new species from the Antarctic Peninsula and the Scotia Arc, is distinguished from all other ligulate members of the genus by the arrangement of zoosporangia, which are produced together with paraphyses in a raised sorus. Among all species in the genus, onlyD. anceps Montagne shares this feature.Desmarestia antarctica is the first species of the genus for which an endophytic gametophyte is demonstrated, the usual host beingCurdiea racovitzae De Wildeman, a red alga of the familyGracilariaceae. The sporophyte contains only a moderate concentration of acid compared to Northern Hemisphere ligulate species, while physodes that probably contain polyphenolic compounds form noticeable speckles and dark margins in preserved plants. Often more than one axis arises from a single holdfast, probably as the result of compounding rather than proliferation.Dedicated to Prof. DrLothar Geitler on the occasion of the 90th anniversary of his birthday.     

The genus periconia from india

Summary Totally 20 species ofPericonia have been studied, of whichP. ellisii, P. hyderabadensis, P. indica, P. masonii, P. pseudohispidula, P. scrobiculata, P. simplex, P. stilbacearum, P. torulosa, P. warticulata, andP. yadagirensis are new, remaining reported for the first time from these parts. The discussion includes comments on the distribution, nature of colonies, fertility of stipes, their arrangement in colonies and its application in taxonomy. Variation in sporoderm is treated.P. parasitica Tilak,P. ipomoeae &P. xanthicola Vasant Rao are treated conspecific withP. byssoides Pers. exSchweinitz, pending the establishment of their parasitism. An improvised and comprehensive key for 28 species ofPericonia known so far from India is proposed.
