A new species ofMarasmius sectionGlobulares, Marasmius brunneospermus sp. nov., found in the lowland forest of Kanagawa and Chiba, Japan, is described and illustrated. This species is characterized by a hygrophanous pileus with rugulose-reticulate disk, well-developed basal mycelium attached to an extensive mycelial mat in leaf litter, and conspicuous fusoid-ventricose pleurocystidia. In addition, its brown spore print mottled with white parts is unusual as an infrageneric character in the genusMarasmius.  相似文献

Psathyrella turcosomarginata is described and illustrated as a new species from Japan (Fukuoka Prefecture, Kyushu). This species is assigned to section Spintrigerae because of its lack of pleurocystidia and basidiome habit. It is characterized by having fairly large basidiomes, a distinct sulcate-striate pileal margin, and cheilocystidia with mucoid deposits that stain bluish green in ammonia solution.  相似文献

Lentinula aciculospora sp. nov. is described from a single Province in Costa Rica. Stature and habit of basidiomata of this species are similar to some otherLentinula taxa (i.e.L. edodes), but the elongate-cylindrical shape of basidiospores is a distinctive character ofL. aciculospora. The mating system ofL. aciculospora is tetrapolar as also found in other species of the genus, but this species is genetically isolated fromL. boryana, and all morphological variants ofL. edodes.  相似文献

Two new species of Agaricales are described and illustrated from Yaeyama Islands, southwestern Japan: (1) Amanita rubromarginata sp. nov. (section Caesareae Sing. ex Sing. in the subgenus Amanita), forming brownish-orange then reddish-yellow pileus, a pale yellow, squamulose stipe with a thin, membranous, reddish-orange annulus and a thick, saccate volva, and reddish-orange marginate lamellae, found in oak forests of Ishigaki Island; and (2) Tylopilus obscureviolaceus sp. nov. (section Tylopilus), having dark purple basidiomata, white, bitter, unchanging flesh, and a finely purplish-reticulate stipe, found in oak forests of Iriomote Island.  相似文献

The genome sequence of the hemibiotrophic fungus Moniliophthora perniciosa revealed genes possibly participating in the RNAi machinery. Therefore, studies were performed in order to investigate the efficiency of gene silencing by dsRNA. We showed that the reporter gfp gene stably introduced into the fungus genome can be silenced by transfection of in vitro synthesized gfpdsRNA. In addition, successful dsRNA-induced silencing of endogenous genes coding for hydrophobins and a peroxiredoxin were also achieved. All genes showed a silencing efficiency ranging from 18% to 98% when compared to controls even 28 d after dsRNA treatment, suggesting systemic silencing. Reduction of GFP fluorescence, peroxidase activity levels and survival responses to H2O2 were consistent with the reduction of GFP and peroxidase mRNA levels, respectively. dsRNA transformation of M. perniciosa is shown here to efficiently promote genetic knockdown and can thus be used to assess gene function in this pathogen.  相似文献

As new records from Japan, Tulostoma adhaerens and T. fulvellum (Tulostomataceae, Agaricales) were described and illustrated based on the specimens collected in Shizuoka Prefecture and Shiga Prefecture, respectively. New Japanese names were proposed as Abata-Keshibouzu-take and Tanemi-Keshibouzu-take for T. adhaerens and T. fulvellum, respectively, based on their morphological features.  相似文献

A Trichoderma harzianum isolate (1051), which was able to antagonize in field the phytopathogen Crinipellis perniciosa, the causal agent of witches' broom disease of cocoa, produces several hydrolytic enzymes. A chitinase, with molecular mass of about 37 kDA, which was secreted by the Trichoderma in the culture medium containing chitin, was partially purified by gel filtration followed by hydrophobic chromatography. The optimal pH and temperature for chitin hydrolysis by the partially purified enzyme were 4.0 and 37 °C, respectively. Chitobiose, laminarin, cellulosic substrates including aryl-glucosides, xylan, starch and -galactomannan were not hydrolysed by the enzyme. Remarkably, the partially purified enzyme drastically affected the cell wall of the phytopathogen C. perniciosa in vitro.  相似文献

Gene egl2 of secreted endo-(1–4)-β-glucanase of glycosyl hydrolase family 5 of the mycelial fungus Penicillium canescens was cloned. The gene was expressed in P. canescens under control of a strong promoter of the bgaS gene encoding β-galactosidase of P. canescens, and endoglucanase producing strains were obtained. Chromatographically purified recombinant 48 kDa protein had pH and temperature optima 3.4 and 60°C, respectively, exhibited specific activity of 33 IU, and had K m and V max in CM-cellulose hydrolysis of 10.28 g/liter and 0.26 μmol/sec per mg, respectively.  相似文献

Actiniceps thwaitesii (Pterulaceae) new to Japan andAnastrophella podocarpicola sp. nov. (Tricholomataceae) are described and illustrated. The former is characterized by forming stipitate-capitate basidiomata under 1 mm tall with encrusted cystidia and acanthophyses. The latter, occurring on a decaying leaf ofPodocarpus macrophyllus, differs from other taxa ofAnastrophella in having undifferentiated hymenial cystidia and smaller basidiospores and basidia. Their cultural features are also presented.  相似文献
