Summary The composition of the endophytic fungal assemblages in Quercus cerris, Q. pubescens and Q. robur, three oak species most susceptible to decline, was investigated in Fagare ` (Padova), Ulignano (Pisa), and Radda in Chianti (Firenze). The endophytic assemblages were studied as a function of health status of the whole tree and of twigs and leaves. The effect of station altitude was tested on Q. cerris. Samples were gathered from healthy and declining trees. In April (bud opening time) 20… Expand
Diversity and significance of fungal endophytes from living stems of naturalized trees from Argentina
TLDR
Fungal endophytes associated with healthy living stems of tree species exotic to Argentina could be considered as sources of potential inoculum for native plants, especially in protected areas, and their potential as important fungal reservoirs to be taken into account in conservation issues is suggested. Expand
Geographical and seasonal influences on the distribution of fungal endophytes in Laurus nobilis
TLDR
Analysis of the total endophytic mycoflora of the sampled trees suggested that geographical factors affects the endophytics distribution patterns more significantly than seasonal factors. Expand
Fungal endophyte communities in declining and vital oak (Quercus robur L.) trees
TLDR
The hypothesis that declining trees harbour a higher fungal diversity was tested in a production forest setting, using older trees and indicated that endophyte communities of Quercus robur L. xylem and bark are more diverse in trees showing some symptoms of decline in comparison to the seemingly healthy-looking trees, but that the diversity was reduced in the most strongly declined trees. Expand
Variation in fungal endophyte communities of pedunculate oak (Quercus robus L.)
TLDR
Compared in young pedunculate oak trees that were surrounded by herbs and shrubs in different combinations and that showed different vitality status, there was no clear pattern of infection from the closest surrounding vegetation, suggesting that the spreading of these fungi occurs at a larger scale. Expand
Monitoring endophyte populations in pine plantations and native oak forests in Northern Spain
TLDR
A change in the endophyte communities was detected due to the deterioration and replacement of native oak forests with pine plantations, which resulted to be closer to and at the same time separated from the ones of P. nigra and P. pinaster. Expand
New pathogenic and endophytic fungal species associated with Persian oak in Iran
TLDR
It could be concluded that for the first time two species, D. glomerata and N. dimidiatum, were recorded as pathogens associated with Persian oak. Expand
Effects of water stress on the endophytic mycobiota of Quercus robur
TLDR
If and in which extent endophytic mycota of adult English oak (Quercus robur) trees are affected by water stress is assessed, and Tubakia dryina and Phomopsis quercina were the most frequently isolated fungi in annual shoots. Expand
Pedunculate Oaks (Quercus robur L.) Differing in Vitality as Reservoirs for Fungal Biodiversity
TLDR
Xylem is more selective substrate for endophytes than bark and that endophyte assemblages in xylem are correlated to the degree of host vitality, confirming that high vitality of trees may be associated with reduced habitat quality to wood-associated endophyts. Expand
Fungal root endophytes of Quercus robur subjected to flooding
TLDR
Fungal colonization was detected in 94% of 1296 root fragments examined, but only 3% of species occurred in all sites, but number of species was higher in roots subjected to floods. Expand
Community structure and preference of endophytic fungi of three woody plants in a mixed forest
TLDR
It is suggested that host and tissue conspicuously affect endophyte community structure in a mixed temperate forest. Expand

Endophytic presence of Discula quercina on Declining Quercus cerris
TLDR
The results indicate that D. quercina is able to live in symbiosis with its host, and the colonization of the aerial parts of Q. cerris is possible through infection with wind-borne inoculum, leaf infection can also occur through overwintering mycelium migrating to the leaves mainly from the buds, but also to a lesser extent from the twigs.

Occurrence of fungal endophytes in twigs of Salix fragilis and Quercus robur.
TLDR
Endophytic fungi of the xylem and bark of Quercus robur and Salix fragilis have been compared to detect interspecific and tissue-specific differences in the communities, revealing a homogeneous distribution of colonization within the samples. Expand
ENDOPHYTIC FUNGI OF RED ALDER (ALNUS RUBRA) LEAVES AND TWIGS IN BRITISH COLUMBIA
TLDR
Ninety percent of the leaves and more than 80% of the twigs were colonized by endophytic fungi; 40 different fungi were isolated and identified and abundance of each fungus species and the species composition depended on the plant organ sampled and collection site. Expand
Endophytic fungi in Quercus cerris : isolation frequency in relation to phenological phase, tree health and the organ affected
TLDR
Individual species were isolated more often from declining trees than from healthy trees, and more fungi were isolated in June (full vegetation) than in April or October, which is probably a serious contributing and inciting factor in the oak decline syndrome. Expand
A comparative study of fungal endophytes in xylem and bark of Alnus species in England and Switzerland
TLDR
Results of cluster analysis show that the different plant organs and tissues examined can be separated on the basis of their endophytic fungi and that characteristic communities of the three Alnus species can be recognized. Expand
Colonisation of leaves and twigs of Rubus parviflorus and R. spectabilis by endophytic fungi in a reforestation site in British Columbia.
TLDR
The suitability of the isolated endophytes to inhibit growth of R. spectabilis and R. parviflorus, which compete with conifers in reforestation sites, is discussed. Expand
Fungi in healthy stems and branches of American beech and aspen: a comparative study
TLDR
Fungi inhabiting healthy stems and branches of American beech and aspen were induced to develop within the wood by drying sections of these organs, and fungi obtained here were termed‘xylotropic endophytes'. Expand
A comparative study of fungal endophytes in xylem and whole stem of Pinus sylvestris and Fagus sylvatica
TLDR
A cluster analysis showed that Pinus tissues can be separated from Fagus tissues on the basis of their endophyte populations, and a K-means cluster analysis revealed that eleven of the fungi isolated were mainly responsible for this separation. Expand
Vegetative compatibility and pathogenicity of Diplodia mutila isolates on oak
TLDR
Forty isolates of Diplodia mutila, a dieback agent on oaks were characterized by their capacity to produce heterokaryons, by their vegetative compatibility, and by their pathogenicity tests on Quercus cerris, which revealed a strong association between these VCGs and host species. Expand
Endophytische Pilze in Blättern und Zweigen von Quercus petraea
TLDR
Surface sterilized leaf and twig samples taken in 1989 from sessile oak (Quercus petraea) in Austria yielded host-specific as well as unspecific ubiquistic endophytes. Expand
