Some of the nicest fungi to photograph are the most common. Golden scruffy aka #Cyptotrama aspratum are a reliable way to make you glad you left the house :)

I'm unlikely to see any more Waxcap species this season but thought I'd post some other interesting CHEGD species. Here's the fabulous Mealy Meadowcap (Pseudotricholoma metapodium). Chunky, pink on bruising and with a beautiful bready smell. Fruits early and is classed as endangered on the red list.

The PCR positivity map is out, and UKHSA is reporting English national positivity at 2.3%.
Adjusted for non-reporting, it's actually 3.53% - not as low as it was in January/February, but as low as in March.
In Scotland it's 2.67%.

Emissions need to fall by at least 50% in 48 months

Profoundly infuriating. Every single barrel of oil pumped moves us deeper into dangerous climate change. The science is absolutely clear about this: the carbon budget to limit to 1.5°C is practically gone. Tipping points loom. We need rapid fossil fuel PHASE OUT.

Waxcap 37 - Vermilion Waxcap (Hygrocybe miniata). A species generally found on more acidic soils. Cap is red/orange but usually closer to orange and slightly domed. Gill attachment is usually adnate. A finely squamulose species best confirmed with microscopy.

Waxcap 42 - Date Waxcap (Hygrocybe spadicea). A very shy fruiting species so not often encountered and also restricted to the better sites. Stipe is yellow with brown fibrils, gills generally yellow but can be orange. The brown conical cap is incredibly distinctive!

Waxcap 41 - Orange Waxcap (Hygrocybe aurantiosplendens). A chunky species and good indicator of special sites. The hygrophanous umbonate cap can start a deep red but is usually orange and fading to yellow. The large contorted stipe is often yellow but can also be orange.

Though I’ve only encountered it a handful of times, the aborted form of the blushing rosette (Abortiporus biennis) is among my favorite fungi! These coral-like projections are not filled with basidiospores, but instead are filled with ellipsoid to subglobose asexual chlamydospores! #Mushrooms
