Trichothelium argenteumR. Lücking & L. I. Ferraro sp. nov. is dis-tinguished by its very large perithecia with a well-developed, silvery white, basally black crown of setae, and by a non-radiate phycobiont. In young perithecia, the setae are confluent and form a characteristic, two-coloured disc-like expansion. Ascospores are 7-septate and bacillar.Trichothelium argenteumis known from a few populations in Costa Rica, Ecuador, Brazil, Paraguay, and Argentina. 相似文献

Two new species of foliicolous lichens from New Zealand are described and illustrated. The most characteristic trait ofDimerella flava sp. nov. (Gyalectaceae) is its pale yellow tubular pycnidia, which clothe the algal-containing thallus on the upper surface of leaves and sometimes also on thin twigs.Porinula setifera sp. nov. (incertae sedis) is closely related to the type species ofPorinula, P. tanzanica, but differs in having hyaline setae on its perithecia and mostly simple paraphysoids. 相似文献

Collections of bionectriaceous fungi from different areas of China were examined, in which 3 new species were encountered. Bionectria intermedia is characterized by smooth perithecia, 2-layered perithecial wall, cylindrical to clavate asci with an apical ring, ascospore striations composed of separate warts, and dimorphic conidiophores. Hydropisphaera yunnanensis has hairy ascomata which are cupulate when dry, clavate asci with a simple apex, and spinulose and very narrow ascospores fusiform and constricted at septum. Nectriopsis apiosporae possesses laterally pinched perithecia when dry, 1-layered perithecial wall, rough perithecial surface, clavate asci with a simple apex, spinulose ascospores with 3 septa, and on Apiospora sp. Four species, Bionectria epichloë, B. kowhaii, B. subquaternata and Hydropisphaera suffulta, are reported as new to China. 相似文献

A new species, Desoria mulyeongariensis, shares some characters with D. choi (Lee), such as the number of setae on retinaculum and apical setae on manubrium. However, it could be easily distinguished from D. choi by the number of ommatidia. This species is also well characterized by having long and thickened smooth macrosetae on the body, and 6 basomedian setae on labium. 相似文献

An ancient fungal parasite of a Camponotus ant (Formicidae: Hymenoptera) in Baltic amber is described as Allocordyceps baltica gen. et sp. nov. (Hypocreales: Clavicipitaceae). The new genus is characterized by an orange, stalked, cup-shaped ascoma with partially immersed perithecia that emerges from the rectum of the ant, two separate stromata with septate mycelium that emerge from the base of the neck and the abdomen of the ant, respectively, and free-standing putative perithecia bearing putative asci with putative multicellular ascospores fragmented into one-celled partspores. This oldest known fossil fungus of an ant could represent a precursor of the genus Ophiocordyceps, which at present is the only fungal lineage parasitizing ants of the genus Camponotus. The fossil shows unique morphological features that existed in the Hypocreales some 35–55 MYA. 相似文献

Three new oribatid mite species, Belbodamaeus indicus sp. n. (Damaeidae), Malaconothrus macrofoveolatus sp. n. (Malaconothridae) and Nothrus phylliformis sp. n. (Nothridae), are described from Indian soils. Belbodamaeus indicus sp. n. is clearly distinguishable from all species of Belbodamaeus by the absence of discidia, very long sensilli and morphology of parastigmatic tubercles Sa. Malaconothrus macrofoveolatus sp. n. is very similar morphologically to Malaconothrus yinae Yamamoto, Aoki, Wang & Hu, 1993 from China, however it differs from the latter by the morphology of notogastral and genital setae, size of body foveolae, epimeral formula, and number of genital setae. Nothrus phylliformis sp. n. is very similar morphologically to Nothrus mystax Mahunka, 1986 from Tanzania, however it differs from the latter by the smaller body size, length of interlamellar setae and the position of notogastral setae d 1. An identification key to known species of Belbodamaeus is presented. 相似文献

Chaetomium globosum Kunze:Fr is a dermatophytic, dematiaceous fungus that is ubiquitous in soils, grows readily on cellulolytic materials, and is commonly found on water-damaged building materials. Chlorate affects nitrogen metabolism in fungi and is used to study compatibility among anamorphic fungi by inducing nit mutants. The effect of chlorate toxicity on C. globosum was investigated by amending a modified malt extract agar (MEA), oat agar, and carboxymethyl cellulose agar (CMC) with various levels of potassium chlorate (KClO3). C. globosum perithecia production was almost completely inhibited (90–100?%) at low levels of KClO3 (0.1?mM) in amended MEA. Inhibition of perithecia production was also observed on oat agar and CMC at 1?and 10?mM, respectively. However, hyphal growth in MEA was only inhibited 20?% by 0.1–100?mM KClO3 concentrations. Hyphal growth was never completely inhibited at the highest levels tested (200?mM). Higher levels of KClO3 were needed on gypsum board to inhibit perithecia synthesis. In additional experiments, KClO3 did not inhibit C. globosum, Fusarium oxysporum, Aspergillus niger, Penicillum expansum, and airborne fungal spore germination. The various fungal spores were not inhibited by KClO3 at 1–100?mM levels. These results suggest that C. globosum perithecia synthesis is more sensitive to chlorate toxicity than are hyphal growth and spore germination. This research provides basic information that furthers our understanding about perithecia formation and may help in developing control methods for fungal growth on building materials. 相似文献

Four new mite species (Bakerdania palustris, B. taymyrica, B. mycophila, and B. littoralis) from different regions of Russia are described. Bakerdania palustris sp. n. is most similar to B. janetscheki Mahunka, 1970, differing in the presence of adjoining bases of setae ps 2 and ps 3 (in B. janetscheki, ps 3 is separated from ps 2) and also by shorter smooth setae 2b (in B. janetscheki, setae 2b are serrate and distinctly longer). Bakerdania taymyrica sp. n. is most similar to B. heisseli Mahunka, 1970, differing in the presence of the brush-like setae 1a (that are trichoid and serrate in B. heisseli); shorter setae tc′ on the tibiotarsus I, that are almost half as long as setae pl′ (in B. heisseli, tc′ is much longer, nearly as long as pl′). Bakerdania mycophila sp. n. is most similar to B. racki (Mahunka, 1967), differing in the presence of significantly longer ventral setae and the separate solenidion ω1 (in B. racki, the latter is fused with the tibiotarsus). Bakerdania littoralis sp. n. is most similar to B. racki, differing from the latter in the shape of setae 1a, 2a, 3a, 3b, 4a that are basally thickened; in the shape of setae ps 1 (trichoid in B. racki); and in the presence of the non-furcated setae 1b (in B. racki, these setae are bifurcate). 相似文献
