Summary The author reviews the European species of the Pteromalid genusCallitula
Spinola and keys them out. All four species develop as parasites, probably all on small Diptera: two species [pyrrhogaster (Walk.) andbicolor
spin.] on Cecidomyids and Chloropids in grass stems, two species are associated withPhragmites communis [C. ferrierei sp. n. andelongatus (Thoms)]. From the latter two one is described as new and in the other (elongatus) the so-far-unknown male is described. *** DIRECT SUPPORT *** A5180147 00002

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).

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

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

Summary The genusGymnoascus
Baranetzky is monographed and found to include five valid species including one previously recognized species,G. reessii, one new combination,G. johnstoni, two new species,G. longitrichus andG. corniculatus, and a species originally described as aGymnoascus but included inMyxotrichum since 1893,G. uncinatus. Twenty species previously described as belonging toGymnoascus are excluded from the genus or are considered as doubtful representatives.Supported in part by Botany Department Research Grant # 1344, University of California, Los Angeles, California. 相似文献

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. 相似文献

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). 相似文献

Summary An investigation of the zoosporic fungi in the vicinity of the Friday Harbor Laboratory, San Juan Is., Washington, revealed the presence of great numbers of fungi. With one exception (Olpidium sp.) these were all biflagellate organisms. Predominating were species (11) of Thraustochytriaceae which abounded in water, in association with seaweeds, intertidal sands, and particularly on the surface of bottom samples down to depths of 298 m. A twelfth species of this group has several peculiarities and needs further investigation. Of the algal parasites, one on Polysiphonia and Pterosiphonia is considered new and termed Eurychasma joycei n. sp.The assistance of Drs. R. E. Norris and G. J. Hollenberg in calling my attention to certain algal parasites is gratefully acknowledged. I am also indebted to my colleague Dr. H. C. Whisler, and to Dr. C. Anastasiou for assistance in photographic work. 相似文献

J. W. G. Lund 《Hydrobiologia》1960,16(1):97-108
Summary
Tetrasporopsis pseudofenestrata and Chrysolykos gracilis are new species. Chrysococcus cystophorus f. astigmata
Skuja and Cyclonexis uraliensis
Pochmann are new British records. Chrysolykos planctonicus
Mack was recorded but not named by Scourfield (1930).The taxonomy of Cyclonexis
Stokes is confused. It is uncertain whether C. annularis
Stokes and C. erinus
Jane are separate species but, if they are, the only definite records of the former are from the U.S.A. The known British populations of C. erinus seem to lack discobolocystes though Hovasse (1949) doubts this. The other European populations may or may not possess these organs. 相似文献

A study of both silicified and nonsilicified specimens of Permian reticularioid brachiopods from South China suggests thatPermophricodothyris, a genus previously rarely reported from China, is actually very common and abundant in the Middle and especially Upper Permian
of South China. This study also clarifies, for the first time, that many of the reticularioid brachiopod species previously
described asSquamularia in fact belong toPermophricodothyris. The new data presented in this paper also allows a critical evaluation ofPermophricodothyris in relation to its closest allies:Phricodothyris, Squamularia, Bullarina andNeophricodothyris. The revision reveals that a total of 18Permophricodothyris species are present in the Middle and Upper Permian of South China, with only one species,P. squamularioides, having survived the Permian-Triassic mass extinction. Two species,P. grandis (Chao) andP. guangxiensis
Han, Zhou & Wang, are redescribed here, providing critical new information on the morphology and taxonomy of these species. 相似文献

Summary A taxonomic study of the members of the family Choanephoraceae was undertaken. Almost all the species of the family have been isolated from various sources in India. Two genera, viz.,Blakeslea andChoanephora have been recognized and a key to the genera has been given. The genusBlakeslea includes only one speciesB. trispora and the genusChoanephora five species. A key to the species has also been given. A new variety ofChoanephora circinans, viz.,C. circinans var.prolifera
Mehrotra andMehrotra based on the proliferating vesicular apices of the sporangiophores has been described. 相似文献
