I just passed my 50,000th identification on @inaturalist.bsky.social! Identifying is a huge but often ignored part of the #iNaturalist community and dataset so I wanted to share why and how I identify. 1/14

Thanks to everyone who came along/tuned in to my PhD exit seminar! What a thing to do at the end of almost four years. So close to submitting, just need to tidy up this last chapter and I’m done! PS does anyone need a mycology/botany genomics/systematics postdoc? 👀

Australian universities are in a governance crisis. VC pay blowouts, scandals, mission drift — these aren’t random, they’re structural.

This new working paper with @marijataflaga.bsky.social & Keith Dowding digs into why the system is broken, and how to fix it.

A thread:
Neither corporate nor government: Why university governance needs to be different, and better
Marija Taflaga, Francis Markham and Keith Dowding.

Preprint, 29 August 2025. https://doi.org/10.25911/MWW4-9781

Abstract
Australian universities face a governance crisis rooted in failures of accountability. Unlike parliaments and corporate boards, university councils lack effective mechanisms for principals to discipline agents. In parliaments, voters can replace elected representatives; in corporations, shareholders can vote out directors. Both systems close the delegation–accountability loop, ensuring alignment between principals and outcomes. University councils, however, are self-perpetuating bodies dominated by external appointees, and in recent decades they are typically from corporate backgrounds. As neither producers nor consumers of universities’ core product—knowledge creation and dissemination—they have minimal intrinsic stake in academic outcomes leaving councils detached from the university’s core mission. This misalignment fosters mission drift, weakens oversight, and contributes to repeated scandals. Because councils largely appoint their own successors, they remain insulated from meaningful scrutiny, unlike boards or parliaments where underperformance is sanctioned externally. Restoring accountability requires giving academic staff and students a renewed oversight role, alongside clear safeguards for the public interest. Because academics and students are both producers and consumers of knowledge, they have a direct and enduring stake in its quality. We recommend two mechanisms to do this are:
1. Academic Senates empowered to appoint and review council members, ensuring councils reflect the university’s purpose.
2. Robust Committee Systems that embed staff and student voices in decision-making, reduce information asymmetries, and align incentives with academic purposes.

My final PhD exit seminar is fast approaching! Tune in if you’d like to hear what I’ve been up to the last four years. There’s something for everyone: fungal genomics and species delimitation (38 new Rhizoctonia genomes), orchid phylogenomics and popgen, fungal taxonomy, it’s gonna be fun 🤙

Would love to be added please!

A lot of it comes down to the initial cost and time investment. It takes a lot to inoculate the trees and treat the soil so that it’s right, but it may be years before you will know whether your setup has worked successfully.

What happened to Rhizoctonia and its Thanatephorus sexual morph?

In this paper, Rhizoctonia and allied genera are reviewed, and 32 new combinations are proposed in Rhizoctonia

In an unconscionable decision, the Smithsonian Institute has decided to no longer support the Biodiversity Heritage Library from 1 Jan 2026. Please someone step up and take it over.

Foundations: please step up and take over the Biodiversity Heritage Library (BHL). This is an absolutely essential scanned archive of all of the old journals and books from the 1500s to about 1920. Has been indispensable for my research.

We argue that the continued use of anamorph/teleomorph-typified generic names in #Ceratobasidiaceae hinders a holistic understanding of this family, when it is clear that pathogenic and symbiotic species are likely united in their fundamental biology.
rpodonnell.bsky.social
We also found a distinct difference in the way certain names are used in the literature: pathogen researchers are more likely to use Rhizoctonia and Thanatephorus; while orchid mycorrhizal researchers are more likely to use Ceratobasidium and Ceratorhiza.
rpodonnell.bsky.social
Names transferred to #Rhizoctonia include species formerly circumscribed within #Ceratobasidium, #Ceratorhiza, #Moniliopsis, #Thanatephorus, #Tofispora, and #Ypsilonidium (among other synonyms).
rpodonnell.bsky.social
We reiterate the fact that the genera within Ceratobasidiaceae are paraphyletic, and formalise the recognition of a single genus; Rhizoctonia. We present 32 new combinations, to make a total of 52 accepted species of Rhizoctonia.
rpodonnell.bsky.social
At long last, our manuscript ‘Rise up, Rhizoctonia: moving to one fungus, one name in the Ceratobasidiaceae’ has finally been published in Persoonia 🎉
Here we resolve several longstanding taxonomic issues within Ceratobasidiaceae and present a unified Rhizoctonia

#mycosky #mycology bluesky! I’m looking for some inspiration - what are some of your favourite recent (published within the last 1–3 years) fungal comparative phylogenomic studies that you’ve read?
rpodonnell.bsky.social
26 freshly sequenced whole genomes of undescribed orchid-associated Rhizoctonia spp. 🤙 14 more genomes to go and then I’m on the home stretch for the PhD 🫨
rpodonnell.bsky.social
After 372 days since submission, and 14 reviewers who committed to reviewing but didn’t wind up submitting a review, our Rhizoctonia nomenclature manuscript has finally been accepted for publication in Persoonia! 🥲

Had such a great time over the weekend talking with artist Keg de Souza and panel chair Richard Morecroft about fungi and the intersections of art and science for ‘Magic Mycelium’ at the Bundanon Art Museum - such an incredible art space and landscape.
