I am starting a PhD and am looking for grassland restoration/rewilding sites in Northern Ireland! Please forward this flier to anyone who might be interested in having their land surveyed for fungi!

Many of my science colleagues are not speaking out-I suspect due to the fear Phil notes, that they'll targeted for loss of funding. I hope they read this account of what happened at a faculty meeting at Frankfurt University in 1933 as the Nazi's took control 🧪

I saw my first Peronospora ficariae of the year yesterday! Look out for yellowed, downturned leaves of Lesser Celandine with branched conidiophores underneath (visible with a hand lens).

A reminder about this free talk next Tuesday! If you are looking for a new group to record this year plant pathogens are a great choice!

Two fabulous sedges from late April on Arnside Knott.
Spring Sedge (Carex caryophyllea) and its rare red relative Carex ericetorum (Rare Spring Sedge).
The beautiful wine red glumes of ericetorum separate these really well in flower/fruit. What beauties! 😍

A major new YouGov poll of 2,600+ people shows:

78% favour solar
63% support onshore wind
70% back offshore wind

And 70% would support a solar farm near their own home.

That’s a landslide.

To round up my year of biological recording, here are my favourite finds from each month of 2025!

January - Jubula hutchinsiae

I re-found this colony recorded in 2004 in the Glen Stream, co. Down. A v interesting & unmistakable oceanic liverwort of humid wooded stream valleys

Having an incredible time down South, milder weather and a lot of fungi still about. Including the weird and wonderful like this White Basket! (Ileodyction cibarium) 😍

I'm learning a programming language called Julia at the minute. Here is a graph I made showing how the probability of a disease going extinct changes as its host plant gets more common in a simulation. There is a clear and sudden phase transition below which there is a collapse in host connectivity.

You can really see my biases in my iNaturalist records from this year. Almost all of the flies are gall midges, almost all the wasps are gall wasps, almost all of the arachnids are gall mites :P
The fungi are well represented this year in pink (1587 records), as are the plants in green (870 records)

1/2 #speciesaday no. 677 is Walckenaeria acuminata. Periscope up! The male of this spider has its eyes spread out along the turret - 4 half way and the other 4 at the top! This genus is an utter joy, I love showing this spider to people for the first time. Even the female has a small protrusion.

A few Wild Radish were flowering in a fallow arable field near Pentireglaze, Cornwall today, with lovely colour hues to the petals.

I wish more people were aware of this. Considering the scale of the threat, the media's near-silence is both remarkable and culpable.

Plant taxonomy is disappearing - and so is our ability to protect species 🍂

Nearly half of countries have fewer than 10 plant taxonomists. Kew is working to close the gap, but we need more experts fast.

Interactions between plant pathogens (left) and plants across five quadrats in a restored species-rich grassland. The basic premise of my PhD is to see if these interaction networks differ between restored and ancient grasslands.
