Differentiation of Ophiostoma piceae and Ophiostoma quercus by Morphology and RAPD Analysis [PDF]

open access: possibleSystematic and Applied Microbiology, 1995
<p>Ophiostoma piceae (Münch) H. and G. Sydow was found to comprise two distinct species by means of morphological investigation on synnematal size as well as by RAPD technique for genomic analysis. The two species are separated undoubtedly by the means of morphological investigations on synnematal size, the onset of a respective yeast ...

On the variability of Ophiostoma piceae

Antonie van Leeuwenhoek, 1989
The morphology and cultural characteristics of Ophiostoma piceae were described on the basis of 22 strains from the CBS collection supplemented with 25 fresh isolates from Poland, mostly from necrotic parts of Quercus robur. The pleomorphism of anamorphs of the fungus is described in detail.

Ascospore Ultrastructure and Development in Ophiostoma Cucullatum

Mycologia, 1991
Ultrastructural aspects of ccyclcpmcnt of hat-shaped ascospores and centrum organization in O. cucullawm were studied and compared with other species in Ceratocystis sensu/ala apparently having similar ascospores. The ascospore wall consisted of a reniform primary and ornamented secondary wall.

Die Wachstumsgeschwindigkeit als Unterscheidungsmerkmal zwischen Ophiostoma piceae und Ophiostoma querci

European Journal of Forest Pathology, 1994
Abstract Vegetative growth as a means of differentiating Ophiostoma piceae from Ophiostoma querci. Isolates of Ophiostoma piceae from spruce (Picea abies) and O. querci from oak (Quercus robur) showed distinct differences in vegetative growth of cultures at a wide range of temperatures.

DNA sequence comparisons of Ophiostoma spp., including Ophiostoma aurorae sp. nov., associated with pine bark beetles in South Africa

open access: yesStudies in Mycology, 2006
BARK BEETLES (COLEOPTERA: Scolytinae) are well-recognized vectors of Ophiostoma species. Three non-native bark beetle species infest various Pinus species in South Africa, and they are known to carry at least 12 different species of ophiostomatoid fungi. Some of these fungi have not been identified to species level.

Ophiostoma longicollum.

2021
Abstract O. longicollum is a perithecial ascomycete that was isolated from the wood of dying oak [Quercus spp.] trees attacked by the wood-boring beetle, Platypus quercivorus, on the west coast of Japan. Neither the pathogenicity of the fungus, nor any definite association with the beetle as a vector, has been established. The beetle

Ultrastructure of ascosporogenesis in Ophiostoma davidsonii

Mycological Research, 1991
The ultrastructural development of asci, ascospores and centrum organization in Ophiostoma davidsonii , was examined. Mechanisms possibly involved in ascospore wall and sheath development, revealed differences between O. davidsonii and Ceratocystis moniliformis .
