==== Given the ecological importance of these fungi, scientists have indeed studied various aspects of fruiting in relation to roots. Here we highlight some relevant scientific works and any mentions of theses: ====
* Fruiting Body–Root Connection Studies: Nilsson et al. (2006)sciencedirect.com<ref>{{cite web|title=sciencedirect.com|url=https://www.sciencedirect.com/science/article/abs/pii/S0953756206002905#:~:text=,identification%20of%20the%20fungal|publisher=sciencedirect.com|access-date=2025-12-30}}</ref>pubmed.ncbi.nlm.nih.gov<ref>{{cite web|title=pubmed.ncbi.nlm.nih.gov|url=https://pubmed.ncbi.nlm.nih.gov/17123810/#:~:text=Abstract|publisher=pubmed.ncbi.nlm.nih.gov|access-date=2025-12-30}}</ref> demonstrated a method to identify mycorrhizal fungi by finding fruiting bodies in direct connection with root tips (as discussed above). Similarly, Rosanne Healy’s work at Harvard Forest (2014) used root-tip sequencing coupled with fruitbody collections to discover new truffle species in an arboretumarboretum.harvard.edu<ref>{{cite web|title=arboretum.harvard.edu|url=https://arboretum.harvard.edu/wp-content/uploads/2020/06/2014-72-2-Arnoldia.pdf#:~:text=University%20arboretum,layer%20from%20the%20root%20tip|publisher=arboretum.harvard.edu|access-date=2025-12-30}}</ref>. These studies show that the physical linkage of a fruiting body to a root apex is not only real but scientifically valuable – it “provides strong indications” of an ectomycorrhizal partnershippubmed.ncbi.nlm.nih.gov<ref>{{cite web|title=pubmed.ncbi.nlm.nih.gov|url=https://pubmed.ncbi.nlm.nih.gov/17123810/#:~:text=Abstract|publisher=pubmed.ncbi.nlm.nih.gov|access-date=2025-12-30}}</ref>.
* Ectomycorrhizal Community Surveys: Numerous ecological surveys pair belowground and aboveground observations. For example, a New Zealand study on invasive pines traced Rhizopogon ectomycorrhizae and matched them to aboveground (actually, belowground in this case) Rhizopogon fruitbodies found nearbypmc.ncbi.nlm.nih.gov<ref>{{cite web|title=pmc.ncbi.nlm.nih.gov|url=https://pmc.ncbi.nlm.nih.gov/articles/PMC2798635/#:~:text=Zealand%20pmc,root%20tips%2C%20were%20obtained|publisher=pmc.ncbi.nlm.nih.gov|access-date=2025-12-30}}</ref>. By analyzing 18 fruiting bodies and 14 root-tip samples, the authors confirmed the same species on roots and in sporocarpspmc.ncbi.nlm.nih.gov<ref>{{cite web|title=pmc.ncbi.nlm.nih.gov|url=https://pmc.ncbi.nlm.nih.gov/articles/PMC2798635/#:~:text=Zealand%20pmc,root%20tips%2C%20were%20obtained|publisher=pmc.ncbi.nlm.nih.gov|access-date=2025-12-30}}</ref>. Such research indirectly documents that the fruitbodies were adjacent to the colonized root tips.
* Mycorrhizal Morphology Theses: While we did not find a thesis dedicated solely to “fruiting at root apex”, many graduate works on mycorrhizae touch on related topics. For instance, a Czech diploma thesis on “Mycorrhizní houby” (mycorrhizal fungi) likely covers how mushroom formation depends on root symbiosisis.muni.cz<ref>{{cite web|title=is.muni.cz|url=https://is.muni.cz/th/379997/prif_m/Plny_text_prace.pdf#:~:text=,jedlov%C3%BDm%20les%C5%AFm%20na%20jihoz%C3%A1padn%C3%AD%20Morav%C4%9B|publisher=is.muni.cz|access-date=2025-12-30}}</ref>. Another thesis in forestry research illustrates Armillaria fruiting on roots of a dead sprucevulhm.cz<ref>{{cite web|title=vulhm.cz|url=https://www.vulhm.cz/files/uploads/2019/03/zlv_2006_04.pdf#:~:text=,na%20ko%C5%99enech%20odum%C5%99el%C3%A9ho%20smrku|publisher=vulhm.cz|access-date=2025-12-30}}</ref> – a parasitic scenario outside our focus, but it shows how fruiting on roots is noted in academic literature. Overall, academic publications emphasize that ectomycorrhizal fruit bodies (mushrooms, truffles, etc.) are usually the reproductive extensions of an unseen mycorrhizal network on rootsmycorrhizas.info<ref>{{cite web|title=mycorrhizas.info|url=https://mycorrhizas.info/ecm.html#:~:text=reproduction,in%20pots%2C%20as%20shown%20below|publisher=mycorrhizas.info|access-date=2025-12-30}}</ref>mycorrhizas.info<ref>{{cite web|title=mycorrhizas.info|url=https://mycorrhizas.info/ecm.html#:~:text=Image%3A%20Laccaria%20fruiting|publisher=mycorrhizas.info|access-date=2025-12-30}}</ref>. This fundamental concept appears in textbooks and review articles, reinforcing that any ectomycorrhizal fruiting event is inherently tied to a root apex (even if the fruiting body doesn’t visibly cling to the root).
* Noteworthy Publications: A few key papers you might find useful include “The Habits of Truffles and Other Ectomycorrhizal Cup Fungi” by Healy (2014), which discusses finding truffle species by examining root tip cluesarboretum.harvard.edu<ref>{{cite web|title=arboretum.harvard.edu|url=https://arboretum.harvard.edu/wp-content/uploads/2020/06/2014-72-2-Arnoldia.pdf#:~:text=University%20arboretum,layer%20from%20the%20root%20tip|publisher=arboretum.harvard.edu|access-date=2025-12-30}}</ref>; and “Underground Networking: The amazing connections beneath your feet” (National Forest Foundation, 2021) which is a layman article describing how mushrooms connect to tree rootsfacebook.com<ref>{{cite web|title=facebook.com|url=https://www.facebook.com/groups/pha.plant.hoarders/posts/582542637475377/#:~:text=So%20the%20mycorrhizal%20fungi%20go,signal%20to%20let%20it|publisher=facebook.com|access-date=2025-12-30}}</ref>. These can provide further references and even photographs/diagrams of root-fungus connections.

For completeness, we scoured databases in multiple languages (English, Czech, Spanish, etc.) for any master’s or PhD theses explicitly studying how the distance of the fruiting body from the root tip affects the fungus. We did not find a thesis specifically on that narrow question. However, several dissertations on truffle cultivation and ecology (e.g. in Italy and France) do discuss factors influencing truffle development (soil conditions, host species, microbial interactions) which implicitly relate to the root zone environment.
