FIRST REPORT OF PHYSARUM COMPRESSUM IN BLACK POPLAR MUSHROOM CROPS IN SPAIN

The commercial cultivation of black poplar mushrooms (Agrocybe aegerita) in Spain is a recent activity, which is carried out in hygienic and climatologically controlled conditions using mainly pasteurised wheat straw substrates. In 2008 the presence of a myxomycete was detected during cropping in several black poplar mushroom crops in Castilla-La Mancha (Spain). Both plasmodium and sporocarps were found on the substrate, on the plastic substrate packing and on the A. aegerita sporophores. The myxomycete was identified as Physarum compressum according to current taxonomic criteria (Lopez and Garcia, 2002; Desrumaux et al., 2003). The growth of this slime mould affects the colour of the caps of A. aegerita carpophores, which turn light brown/ beige, lowering their quality to such an extent that the mush- rooms become unmarketable. The inoculation of plasmodium and spores to healthy A. aegerita fruiting bodies resulted in no plasmodium development or colour loss in the caps. Two crop cycles involving 100 blocks of substrate per cycle, were moni- tored, from the incubation phase to the end of harvesting in or- der to assess the presence of the myxomycete, which was found in 12 and 65, respectively, of the cultivated blocks. P. compressum has previously been described in intensive Pleurotus cultures that use pasteurised substrates similar to those employed for cultivat- ing A. aegerita (Desrumaux et al., 2003). To the best of our knowledge, this is the first report of P. compressum in black poplar mushroom farms in Spain.

Observations on Physarum Hongkongense (Physarales, Myxomycetes) from Taiwan

A plasmodiocarpous species of Physarum, P. hongkongense, is discovered from northern Taiwan. Previously it was known only from Hong Kong. Observations were made with light microscopy, and its distribution in Taiwan is illustrated by a map. A key to the plasmodiocarpous species of Physarum with double or triple peridia known from Taiwan is also given.

Slime Molds and Myxomyceticolous Fungi from Taoyuan, Taiwan

A total of 56 taxa of slime molds and myxomyceticolous fungi of Taoyuan County, Taiwan have been enumerated, of which 44 taxa are new to Taoyuan county. Didymium flexuosum and Physarum superbum are newly reported for Taiwan.

アメーバ型運動細胞の食作用と走化性（太陽虫，アメーバ，粘菌）

Chemotaxis and feeding behavior in Actinosphaerium, Amoebaa nd Ph ysarum are reviewed together with new results.Studies in giant amoeboid cells may provide new aspects on the mechanism of behaviors in amoeboid cells in general.Actinosphaerium released attractant chemicals to prey organisms such as Tetrahymena. The attracted organisms were catched by adhering to axopods. The catched organisms were stored there until food vacuoles incorporated them into the cell body. The adhesiveness to prey organisms takes no decisive role in feeding behavior of Amoeba.By applying a double-chamber method, chemotactic behavior of Amoeba was expressed as an averaged deviation, ΔP, in the motive force of protoplasmic streaming.ΔP exceeded by10cm H2Oin chemotaxis as well as during spontaneous formation of uroid at the tail of Amoeba.Intracellulat perfusion technique was applied to plasmodial strands of Physarum. Injected ATP, Ca2+and KCl had effects on the contractility and morphology comparable to those in extracted actomyosin such as ATPase activity, solubility, etc.Thus, dialized plasmodial strands will be an ideal system in studying chemoreception, transduction mechanism and regulation of contractility.
