  AQUATIC SPECIES OF PYTHIUM FROM CHINA

  Mycosystema. 1988, 7(Z1): 21-33.

  Abstract ( ) HTML   Knowledge map   Save

  In this paper, eight aquatic species of the genus Pythium from China are reported. They are:P. aquatile. P. cli.ssotoc.um. P.intcrmutlium, P. midrlletonii, P. myriotylum, P. periplocum. P. rostratum and P. torulosum. Among them, P. uquutili, is a new record in China;P. myriotylum is the first isolation from water in the world. All the species included in this paper excep:P.nfiddIutonii are isolated for the first time from water in China, and six of them are described and illustrated. The strains identified as P. middletonii and P. rostratum, which exhibit no difference from those which were reported from other habitats before. are listed and discussed.

  MONOSPOROUS VARIETIES OF SYNCEPHA LASTRUM

  Mycosystema. 1988, 7(Z1): 35-52.

  Abstract ( ) Download PDF ( ) HTML   Knowledge map   Save

  A new species. Syncephulusrrum monosporum sp. nov.. consisting of three varieties, var. monosporum, var. c.risrarum var. nov., and var. pluriproliferum var. nov. is described. All varieties differ from the monotypic species of the genus, Syncephalasrr racemosum Cohn ex Schroeter. by possessing only unispored sporangiola (merosporangia) instead of several-spored merosporangia. These are the first reports of monosporous merosporangia in any true Mucorales. Reasons for referring the new taxa to the genus Syncephalasrrum and not erecting a new genus to accommodate them, as well as the'differences among the new taxa themselves, are briefly discussed.

  ELECTROPHORESIS AND THE CLASSIFICATION OF SYNCEPHALASTRUM

  Mycosystema. 1988, 7(Z1): 53-60.

  Polyacrylamide gel electrophoretic studies of protein patterns and esterase zymograms of one isolate of the known, monotypic species of the genus Syncephulasrrum. S. racemosum Cohn ex Schroeter (Sl) and six isolates of the three monosporous varieties belonging to the same new species recently reported in this genus, S. monosporum Zheng el 01. var. monosporum (S7, S8, S9), var. cristarum Zheng er al. 610, S11), and var. pluriproliferumZ heng er al. 612) have been conducted. Marked differences of the four taxa and similarities of different isolates in the same taxon were shown in both protein patterns and esterasc zymograms. Similarity percentages calculated also revealed that the three new varieties were closely related to each other and all of them were, though in less degree, closely related to S. racemosum too. These results are thought to be helpful in confirming the establishment of the three new varieties as well as their inclusion in the same species and also in the same genus with S. racemosum based on morphological studies. Polyacrylamide gel electrophoresis is thought to be a useful supplementary tool for classifying Syncephalasrrum.

  IDENTIFICATION OF Rhizopus BY ELECTROPHORESIS OF PROTEINS AND ESTERASES

  Mycosystema. 1988, 7(Z1): 61-71.

  Abstract ( ) Download PDF ( ) HTML   Knowledge map   Save

  An electrophoretic study of the buffer soluble mycelial protein and esterases of 24 isolates of 10 species or varieties of Rhizopus was carried out to obtain further information on the taxonomic relationships in the genus. Protein profiles were reproducible when the entire procedure of culturing, extraction and electrophoresis was repeated at different times under strictly controlled conditions with the same isolate. Under identical conditions, each species of Rhizopus produced a characteristic protein pattern. Intraspecific isolates generally gave very similar protein patterns and esterase zymograms, especially so with well-defined species like R. stolonifer and R. circinans. Protein patterns and zymograms of esterascs an consequently thought to be able to play an effective supplementary role in the classification of Rhizopus.

  A CONSPECTUS OF THE LICHENIZED ASCOMYCETES UMBILICARIACEAE IN CHINA

  Mycosystema. 1988, 7(Z1): 73-106.

  Abstract ( ) Download PDF ( ) HTML   Knowledge map   Save

  Henssen (1974) distinguished five apothecial types:biatorine, lecideine, lecanorine, zeorine, and superlecideoid. Both the biatorine and lecideine types belong to the lecideine type in a broad sense, and the superlecideoid, the lecanorine and zeorine to the lecanorine type in a broad sense. The apothecium structure of some species of Umbilicariaceae has been investigated by light microscopy (LM). According to the apothecium structure and the origin of the amphithecium, it is clear that the apothecium of Umbilicaria virginis and U. rigida with a thalline rim around the disc lacking algae in it belong to the lecanorine but not to the lecideine type in a broad sense. Inconsequence the term "superlecideoid" or "superlecideine" might better be replaced by "sublecanorine" for the apothecium type of the Umbilicariaceae. Fourty six taxa belonging to 37 species occur in China, including 1 species new to science (Umbilicaria pseudocinerascens). and 11 taxa, including 3 varieties, belonging to 11 species new to China are reported. A taxonomic revision of some taxa has also been made, and keys to species are provide.

  The Systematic Mycology &Lichenology Laboratory (SMLL) was established on 12 August 1985, in Beijing. It was among the first batch of nineteen open labotories / institutes set up by Academia Sinica. The Laboratory was founded on the basis of the Department of Mycology, Institute of Microbiology, Academia Sinica. Although it is subordinate to the Institute of Microbiology of Academia Sinica, it is relatively independent in its research work and conducts scientific activities on its own.
