The fungus was not able to infect intact leaves, but necrotized the margins of foliar disks and caused necrosis and white rot in woody tissues. In dual cultures, P. lycii and Aureobasidium pullulans showed mutual antagonism. Mycoparsitism of P. lycii was observed on epiphytic Botrytis cinerea, Alternaria sp., and endophytic Botryosphaeria dothidea interaction partners. In contrast, P. lycii showed trophic growth towards endophytic Phaeomoniella chlamydospora without any signs of harmful interactions. Dual inoculations of foliar disks with epiphytic fungi revealed no effects of fungal interactions on necrosis development by pathogens and verified mycoparasitic interactions in planta. Co-infection assays of cuttings with endophytic pathogen fungi showed cumulative effects of fungal interactions on wood symptom expression, with the exclusive contribution of P. lycii to white rot development. In addition to providing the first isolation of P. lycii from grapevine and the description of its mycoparasitic behavior, the present study suggests that the fungus may act as an opportunistic grapevine pathogen, probably as a secondary colonizer in trunk diseases. The observed dual host preference may allow trunk disease pathogens to initially feed on fungi, followed by damage to the grapevine. This may be in connection with the exceptionally long latency of these syndromes.<\/jats:p>","DOI":"10.3390\/jof12050348","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T14:05:46Z","timestamp":1778162746000},"page":"348","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Peniophora lycii Isolate Simultaneously Parasitizes Vitis vinifera Host and Associated Fungi, and Possibly Contributes to Grapevine Trunk Disease Development"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9893-6934","authenticated-orcid":false,"given":"Nikolett","family":"Moln\u00e1r","sequence":"first","affiliation":[{"name":"Food and Wine Research Institute, Eszterh\u00e1zy K\u00e1roly Catholic University, Le\u00e1nyka Utca 8\/G, H-3300 Eger, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D\u00f3ra","family":"Szab\u00f3","sequence":"additional","affiliation":[{"name":"Food and Wine Research Institute, Eszterh\u00e1zy K\u00e1roly Catholic University, Le\u00e1nyka Utca 8\/G, H-3300 Eger, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrienn","family":"Gomba-T\u00f3th","sequence":"additional","affiliation":[{"name":"Food and Wine Research Institute, Eszterh\u00e1zy K\u00e1roly Catholic University, Le\u00e1nyka Utca 8\/G, H-3300 Eger, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5324-0564","authenticated-orcid":false,"given":"\u00c1d\u00e1m","family":"Nov\u00e1k","sequence":"additional","affiliation":[{"name":"Food and Wine Research Institute, Eszterh\u00e1zy K\u00e1roly Catholic University, Le\u00e1nyka Utca 8\/G, H-3300 Eger, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8303-5887","authenticated-orcid":false,"given":"K\u00e1lm\u00e1n","family":"V\u00e1czy","sequence":"additional","affiliation":[{"name":"Food and Wine Research Institute, Eszterh\u00e1zy K\u00e1roly Catholic University, Le\u00e1nyka Utca 8\/G, H-3300 Eger, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zolt\u00e1n","family":"Kar\u00e1csony","sequence":"additional","affiliation":[{"name":"Food and Wine Research Institute, Eszterh\u00e1zy K\u00e1roly Catholic University, Le\u00e1nyka Utca 8\/G, H-3300 Eger, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,7]]},"reference":[{"key":"ref_1","first-page":"739","article-title":"Beitr\u00e4ge zur Kenntnis der Corticieen: II.
