This small fungus was found alone on a rotting log, though others were also found in groups.

They had a purple cap with lots of yellow hairs which were lighter where the stem met the cap.

The stem was 40mm tall and whitish before yellowing quickly further down.

The flesh was a light purple colour.

I found some others later throughout the Fen woodland walk.

On Day 6 (23 October 2022), they had grown and spread further throughout the woodland:

The cluster above were all juvenile Armillaria,

They had the same fibrous stems fading to pink at their bases and brown caps with yellow spikes at their edges.

Their stems were 60mm tall while their caps were 15mm across.

Some of them were decapitated revealing the stem’s solid white flesh.

I saw them again on Day 7 (29 October 2022).

They had darker, spotted centres and wavy pink edges.
