While YOLOv8-based deep learning approaches have previously been applied in phenotypic analyses of edible mushrooms, the applicability of newer YOLO architectures to fungal phenotyping remains largely unexplored. In this study, we present a controlled-environment digital phenotyping framework for indoor mushroom cultivation and conduct a systematic benchmarking evaluation of YOLOv11 for phenotypic segmentation in comparison with YOLOv8. Using bottle-cultivated Pleurotus ostreatus and Flammulina velutipes as representative edible basidiomycetes, we performed a controlled comparison of YOLOv8-seg and YOLOv11-seg using identical datasets, preprocessing pipelines, and hyperparameter configurations. The results demonstrate that YOLOv11 achieves segmentation performance comparable to that of YOLOv8 across all evaluated metrics (\u0394mAP50\u201395 &lt; 0.01) while substantially reducing computational complexity, including fewer trainable parameters, lower FLOPs, and decreased gradient load. Validation against caliper-based physical measurements revealed moderate, trait-dependent agreement, whereas inter-model consistency between YOLOv8 and YOLOv11 remained consistently high across diverse morphological and segmentation scenarios. These findings suggest that recent developments in object detection architectures can improve computational efficiency without compromising phenotypic measurement fidelity. More broadly, this study highlights the importance of periodically evaluating emerging detection architectures within biological phenotyping pipelines to ensure scalable, sustainable, and high-throughput fungal phenotyping under controlled-environment cultivation systems.<\/jats:p>","DOI":"10.3390\/jof12040232","type":"journal-article","created":{"date-parts":[[2026,3,24]],"date-time":"2026-03-24T12:58:59Z","timestamp":1774357139000},"page":"232","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative Evaluation of YOLOv8 and YOLOv11 for Digital Phenotyping of Edible Mushrooms Under Controlled Cultivation Conditions"],"prefix":"10.3390","volume":"12","author":[{"given":"Doo-Ho","family":"Choi","sequence":"first","affiliation":[{"name":"Mushroom Research Division, National Institute of Horticultural and Herbal Science, RDA, Eumseong 27709, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youn-Lee","family":"Oh","sequence":"additional","affiliation":[{"name":"Mushroom Research Division, National Institute of Horticultural and Herbal Science, RDA, Eumseong 27709, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4785-0825","authenticated-orcid":false,"given":"Minji","family":"Oh","sequence":"additional","affiliation":[{"name":"Mushroom Research Division, National Institute of Horticultural and Herbal Science, RDA, Eumseong 27709, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eun-Ji","family":"Lee","sequence":"additional","affiliation":[{"name":"Mushroom Research Division, National Institute of Horticultural and Herbal Science, RDA, Eumseong 27709, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung-I","family":"Woo","sequence":"additional","affiliation":[{"name":"Mushroom Research Division, National Institute of Horticultural and Herbal Science, RDA, Eumseong 27709, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minseek","family":"Kim","sequence":"additional","affiliation":[{"name":"Mushroom Research Division, National Institute of Horticultural and Herbal Science, RDA, Eumseong 27709, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji-Hoon","family":"Im","sequence":"additional","affiliation":[{"name":"Mushroom Research Division, National Institute of Horticultural and Herbal Science, RDA, Eumseong 27709, Chungbuk, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1177\/108201320000600206","article-title":"Production of shiitake mushroom (Lentinus edodes) on ligninocellulosic residues","volume":"6","author":"Morais","year":"2000","journal-title":"Food Sci.
