Russula (red cap) forming ectomycorrhizal relationships while Galerina and Mycena species (orange and pale yellow caps, respectively) decompose a wide variety of substrates.

New paper!
Here we saw how ectomycorrhizal, fungi exhibit a certain degree of functional redundancy, as different species can perform similar ecological roles, while saprotrophic fungi display higher niche complementarity. Hope you like it!

Mal any per collir bolets al PNIN de Poblet https://youtu.be/3G9cgis_CV0 La temporada de bolets arriba al seu punt àlgid i ho fa amb males notícies a la zona del Paratge Natural d'Interès Nacional (PNIN) de Poblet. La falta de pluges a fina...

Tot i no haver trobat bolets comestibles al bosc de Poblet, sí hem vist un bon nombre d'espècies sapròfites més petites, especialitzades en degradar pinassa i pinyes.
Per tant, aquests fongs podríen reduïr la biomassa combustible en futurs incendis forestals 🍄🪵🌲🔥

Root anatomy governs bi-directional resource transfer in mycorrhizal symbiosis Plants form mycorrhizal symbioses to enhance nutrient acquisition, yet the biophysical principles governing carbon and nutrient exchange remain unclear. Here, we develop a theory of bi-directional carbon–nutrient transfer that integrates root anatomy, energetic costs, and mycorrhizal positioning. We show that nutrient uptake per unit carbon or energy investment declines with increasing root diameter due to higher carbon demands across thicker cortical tissues. Mycorrhizal fungi mitigate this constraint by enabling more carbon-efficient nutrient uptake, particularly when arbuscules are positioned in inner cortical layers. This spatial optimization minimizes the carbon cost of transporting nutrients to the stele. Our framework reconciles anatomical variation, symbiotic structure, and functional efficiency across root types and mycorrhizal strategies and offers a new lens for understanding the coevolution between roots and mycorrhizal fungi.

Hey, can you add me please? 😊
Many thanks!!

Autumn is always a hard-(field)working season, but these colourful species make it all worth it 🖤
