A new species of Lamproderma (Myxomycetes) from Costa Rica

Lamproderma magniretisporum, a new species of myxomycete from Costa Rica, is described and illustrated. This new species is characterized by its lignicolous habitat, long stalk, dark radial capillitium, large spores, and reticulate spore ornamentation. The stability of the taxonomic characters of L. magniretisporum is supported by two well-developed collections. The morphology of the sporocarp was subjected to detailed study with both the light microscope and the scanning electron microscope. Micrographs of all relevant features are presented. Taxonomic novelty Lamproderma magniretisporum G. Moreno, C. Rojas, S.L. Stephenson & H. Singer     

Soil fungi from orissa (India) IV. Soil fungi of paddy fields

Summary A total number of 165 fungi representing 51 genera have been isolated from 22 soil samples collected at various stages of cultivation and crop growth from paddy fields of Orissa. Many rare fungi as well as two gymnoascomycetous fungi new to science have been isolated. Certain of the fungi were found to be ecologically mature and dominant in the paddy fields and were present during all the stages of cultivation or growth of paddy plants. Not much difference in the species of fungi was observed to exist between Cuttack and Sambalpur plots, between fertile and less fertile plots but a definite difference was found between the fungal flora of dalua and main crop seasons. Among the four media used, rose bengal streptomycin agar was found to be the best isolation medium.     

Myxomycetes from Thailand

Thirty–four species of mycomycetes are reported, mostly from northern Thailand, of which sixteen are new records for Thailand. Cribraria rufa is reported from tropical latitudes for the first time.     

A new species of Didymium (Myxomycetes) from subantarctic Macquarie Island

A series of specimens of a stalked Didymium collected during an intensive survey of fungal biodiversity on subantarctic Macquarie Island were determined to represent a species new to science. The new species Didymium macquariense is described and compared with other morphologically similar species. Micrographs of the most important morphological characters are provided.     

Myxomycetes from Israel IV

Ten taxa of myxomycetes growing mainly withEucalyptus, oak and pine are described. They were found in Upper Galilee, Mt. Carmel and Central parts of the country and all are new to Israel.     

Nivicolous Myxomycetes from tyrol (Austria). I

25 taxa of Myxomycetes collected around melting snow banks in montaneous and alpine areas of Tyrol are presented. From a chorological point of view especially interesting are: Diderma asteroides, D. lyallii, D. peyerimhoffii, Didymium nivicolum, Hemitrichia abietina, Physarum alpestre, Trichia persimilis, Trichia sordida var. sordida, Trichia sordida var. sordidoides. The nivicolous taxa Badhamia alpina and Didymium wilczekii are considered to be synonyms of Badhamia foliicola and Didymium dubium. SEM micrographs of spores and capillitia of the most significant species are included.     

黏菌分类学史研究

黏菌是菌物中一个特殊和有趣的类群。为了准确而深刻地认识黏菌的内涵、多样性和系统发育关系等分类学问题,本文从黏菌命名起点开始循览黏菌分类学的发展历程,结合黏菌分类学的最新研究进展,考证了黏菌纲Myxomycetes内涵的变化和分类系统的演变及黏菌分类学研究的重要事件,并论述了中国黏菌分类学研究史,从而系统阐述了国内外黏菌分类学研究历史的沿革和演化。     

广西粘菌考录

广西横跨北回归线 ,是我国生物多样性高度丰富的地区之一 ,但对这一地区的粘菌从未有过专门的研究 ,此前仅有 1 9种粘菌被记载。为了丰富对广西粘菌资源和物种多样性的认识 ,同时也作为国家热带菌物资源调查项目工作的组成部分 ,作者进行了广西粘菌的资源和分类研究。通过野外采集和基物湿室培养获得粘菌标本 2 49份 ,经鉴定、分类和对原有 1 5份广西产粘菌标本的复核 ,确定了 63个单元 ,它们分属于 6目 1 0科 2 5属 ,其中 6种目前在国内仅知分布于广西 ,另有 46种为广西首次记录。该汇录报告了广西产粘菌的已知种 ,考证标本全部保存在中国科学院微生物研究所真菌标本馆 (HMAS)。     

云南黏菌汇录

云南是我国生物多样性高度丰富的地区之一,蕴藏着丰富的黏菌资源。根据作者的研究、复核和考证,作者汇录了目前已知的分属于6目10科33属的云南黏菌135种10变种,其中27种为云南省首次记录,团孢发网菌(Stemonitis uviferaT.Macbr.)为中国新记录种。     

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.     

New and interesting Myxomycetes from Norway

Forty–nine species of myxomycetes are reported as new to Norway. Of these, 22 species are new to Scandinavia. Several have not, or only rarely, been reported from Europe. Two species (viz. Diderma subfloriformis and Comatricha anomala) were previously known only from their type localities. Brief discussions are given for some of the more interesting species.
