A fungus believed to be a member of the Microthyriales is described from the English Wealden. It occurs on the shoots of an undescribed conifer resembling Frenelopsis Schenk. From the structure of the thyrothecium and the presence of an epicuticular mycelium, the fungus is classified in the family Micropeltaceae, subfamily Stomiopeltoideae, and is described under the name Stomiopeltites cretacea gen. et sp. nov. It is the earliest fossil record of the Microthyriales. 相似文献

A new aquatic fungus was isolated from submerged, decaying leaves collected at Phu Quoc Island in Vietnam. The fungus produced hyaline, unique-shaped conidia consisting of a hook-shaped main axis and three arms at the helicoid part of the main axis. Based on its conidial development and morphological characteristics, Hamatispora phuquocensis was newly introduced. Phylogenetic analyses based on LSU nrDNA sequences showed that it clusters with Microthyrium spp. and belongs to Microthyriales. Furthermore, we generated ITS barcode for this hyphomycetous fungus. 相似文献

This paper presents the reinterpretation of the taxonomic position of fossil epiphyllous callimothalloid fungi belonging to the fossil-genera Callimothallus (hitherto classified to the family Microthyriaceae) and Cribrites (?Microthyriales). These fungi thrived from the Late Cretaceous up to the Holocene. Investigation are based on collected material from the Oligocene of Hungary and the Miocene of Poland and on published data. For the common callimothalloid fungus Callimothallus pertusus, a new combination Neomycoleptodiscus pertusus is proposed. Callimothallus quilonensis is assigned to a new fossil-genus Muyocopromyces as a new combination Muyocopromyces quilonensis. We reconsider the fossil-species Ratnagiriathyrites hexagonalis as a younger synonym of the fossil-genus Cribrites. The geographical range of fossil callimothalloid fungi and their recent counterparts are discussed. Fossil Neomycoleptodiscus, Muyocopromyces, and Cribrites are proposed as reliable climate proxy of warm climate conditions in the past. 相似文献

A new species of mycelium-forming yeast,Endomycopsis platypodis Baker et van Rij is described. It occurs as an auxiliary ambrosia fungus of the wood-boring ambrosia beetlePlatypus cylindrus Fab. (Col. Platypodidae) and is the first fungus to become established in new tunnels where it forms a sparse irregular lining. Later a palisade-formingSporothrix becomes the dominant fungus in a mixed ambrosial flora.
E. platypodis, which is apparently homothallic, assimilates nitrate and weakly ferments glucose. The asci typically contain 4 hat-shaped ascospores. Assimilation reactions and morphology are described and the affinities of the new species are discussed. 相似文献

A new species ofAtkinsiella (Lagenidiales, Oomycetes),Atkinsiella parasitica is described and illustrated. It was isolated from the eggs and bodies of a rotifer,Brachionus plicatilis, with fungal infection in 1992. The rotifer was reared in a hatchery as the first food supply for seed production of crustaceans and fishes. The fungus is characterized by producing monoplanetic, lateral biflagellate zoospores, and infrequently branched discharge tubes. Optimum temperature for the fungus was 25°C. The fungus was considered an obligate marine fungus, because its growth was observed only on PYGS medium including seawater. 相似文献

Caulochytrium is a unique genus of chytrids characterized by the production of both sessile zoosporangia and aerial sporangiocarps, the latter unknown in other chytrids. The type species, C. gloeosporii, is an obligate parasite on conidia of the fungus Gloeosporium. The newly described species, C. protostelioides, which was discovered first in the British West Indies and then in North Carolina, is an obligate parasite of the dematiaceous fungus Cladosporium. It differs from the type species in microdimensions, smaller number of zoospores per aerial sporangium, lack of sexuality, production of protostelid-like sporangiocarps that do not parasitize the host and which float freely on water, and an unrelated host fungus. The family Caulochytriaceae and genus Caulochytrium are emended. 相似文献

The chemical effect of Marasmius peronatus on beech litter is described, with particular reference to the ecological relation between fungus and substrate. Beech leaves, some infected, and others uninfected by this fungus, were analysed and the results compared.
Analysis shows that a vital process involving loss of carbon is at work, and that the fungus decomposes lignin, converting it into soluble products by the action of exoenzymes. It is suggested that by this process it is contributing to conditions favourable for beech regeneration.
The fact that this fungus can more successfully colonize hardwood litter (e.g. beech) than other types of substrate, is explained by consideration of its physiology. 相似文献

Coprophilin, a decalin pentanedienoic acid methyl ester, was isolated from an unidentified fungus by bioassay guided separation. It inhibited (MIC = 1.5 μM) the growth of Eimeria tenella in an in vitro assay. The isolation, structure elucidation, absolute stereochemistry and biology are described. 相似文献

Volvariella volvacea (Bull. ex Fr.) Sing. is a large pileate edible fungus of the tropics and sub-tropics. It has two kinds of spores, one being the sexual basidiospores in tetrads and the other the asexual chlamydospores. Both monosporous and vegetative hyphae are multinucleate, and there are no clamp connections. Fifty monospores were isolated from two fruiting bodies, and were cultivated individually with four replicates under controlled laboratory conditions. On the average, 76% of the monosporous progenies were fertile. The fungus is homothallic. The development and life cycle of the fungus are described. The possible mechanisms of homothallism are also discussed. 相似文献

A novel acidophilic fungus was isolated by an acidic enrichment culture of microbial mats and biofilms collected at an extremely
acidic and high temperature hot spring. In culture studies, this fungus was revealed to produce ascomycetous teleomorph structures.
Molecular phylogenetic study and morphological observation showed this fungus is a new species of the genus Teratosphaeria (Capnodiales, Dothideomycetes) and is phylogenetically close to Acidomyces acidophilus and Bispora sp., which were previously reported as acidophilic anamorphic fungi. This new fungus is described here as a new species of
Teratosphaeria, and its physiological properties adapting to its habitat are demonstrated. This is the first report of a teleomorphic fungus
having highly acidophilic and thermophilic properties. 相似文献

A simple visual method to estimate the linear growth rate of fungal mycelia on stacked straw is described. It has been used to evaluate the growth of the fungus Pleurotus sajor-caju on pasteurized and steam-exploded straw. The maximum linear growth rates ranged from 0.92 to 1.0 cm/d with the two treatments; the fungus seemed to be able to overcome inhibition of its growth. No growth was observed on straw treated with ammonia. 相似文献

Thalassochytrium gracilariopsidis gen. et sp. nov. is an endosymbiotic, polycentric, zoosporic fungus that infected cultures of the red alga Gracilariopsis sp. Based on the posteriorly uniflagellate zoospore and the platelike cristae of the mitochondria, the fungus is placed in the Chytridiomycota. Ultrastructurally, the fungal zoospore is distinguished by the anterior position of the kinetosome, a unique microbody-lipid globule complex, an electron-opaque helix associated with the kinetosome and lipid globules, and a beaked nucleus. Zoospores are positively phototactic, and the unusual helix might constitute part of the photosensory apparatus. Zoospores lack certain taxonomically important structures, such as a rumposome, props, a nonflagellated kinetosome, and flagellar roots. The organism does not fit into any described genus, and the features of its zoospore differ from those of any described order. The fungal thallus is polycentric with multinucleate, septate hyphae. Haustoria form within the algal cells. The fungus does not appear to cause major harm to its host and seems to be host specific. However, during intense sporulation of the fungus, degradation of host chloroplasts was observed in medullary cells. 相似文献
