I found a cool cordyceps on a stink bug the other day! Pretty rad! What do you think?

Some folks have reached out about the photos I've taken of ectomycorrhizal root tips. I wrote a short article about this for my brand-new Substack. If this sort of long-form content interests you, please subscribe and let me know if you want to see more!

A recent article I wrote for the JSTOR Daily about mycorrhizal fungi and the carbon cycle. Features my photos as well. Check it out.

Ergothioneine is a unique antioxidant with many promising health benefits, including for cognitive health. As this study shows, arbuscular mycorrhizal is crucial in the uptake of this compound by plants, as it is almost exclusively produced by fungi.

Very excited to see this work out by visiting PhD in my group Yuanhao Zhang exploring interactions between clonal plant integration and CMNs! Spoiler they interact in big ways! doi.org/10.1111/ppl....

Capacity to form common mycorrhizal networks reduces the positive impact of clonal integration between plants

Ectomycorrhizal structures are produced by an incredible diversity of fungi. In this new study, researchers documented a fusarium forming EM structures and improving plant health.

Me neither, would be interesting to read it in detail. Apparently they isolated it from soil taken from a coniferous forest.

And I though Lycoperdon perlartum (Common puffball) was saprobic. This study shows it forms ECM relationships with populus and may improve their resistance to drought.

The first description of mycorrhizae was published in 1885, where A.B. Frank first coined the term. His study, commissioned by the Kingdom of Prussia, explored the potential for truffle cultivation. Despite it's age, it's insightful to anyone interested in the subject.

An undescribed purple Cantharellus sp. from Tepoztlan, Morelos. Beautiful species, most likely forming mycorrhizal associations with Oak.

I've been looking for EM root tips to photograph with minimal experience in the field. While this study focuses on Himalayan fir, their description of morphotypes is insightful regarding the grand anatomical diversity of these brilliant structures.

I am not a researcher but a communicator who is very enthusiastic about mycorrhizae and would be happy to be included.

Lactarius indigo is a delicious ectomycorrhizal species found with Oak and Pine in Mexico, Central America, and the eastern United States. There are numerous varieties, which may be broken up into several different species soon. I took this picture near my home in Morelos, Mexico last season.

Interesting study by Chinese researchers shows that ECM trees in tropical forests sequester more carbon in N-rich soils, while AM tree diversity rises in P-rich soils but stores less carbon. This may be due to lower AM fungal abundance, making AM trees more prone to pathogens.

This new study outlines how canopy trees & understory shrubs can host the same species of ectomycorrhizal fungi. It finds that oaks & pines form overlapping ECM assemblages with Hazel when growing in proximity.

It reminds me of some Cavendishia I've seen in the highlands of Central America. Ericaceae are so cool.

The common idea that plants "warn" each other of threats through mycorrhizal networks might not be correct, according to this fascinating research. Instead, fungi may act like whistleblowers, detecting plant stress and signaling others in their network to prepare their defenses.

Toby Kiers @tobykiers.bsky.social · Jan 22

Are plants more likely to be ‘eavesdroppers’ than altruists when tapped into fungal networks?

Before their extinction 600 years ago, the giant flightless Moa ate and dispersed truffles. This was likely true for many of the 41% of bird species now extinct in New Zealand. What is the best way to approach species conservation when the mutualist dispersers are now extinct?
