Fuligo septica at Strumpshaw Fen – May 2024

1 June 2024

In early May — near The Outpost — we saw our first Fuligo septica of the year — a mature aethalium on the verge of disintegrating.

And nearby a Fuligo septica plasmodium.

Which a week later had already matured losing it’s peridium exposing the spore mass.

Adjacent, a new small aethalium had developed.

Just outside The Outpost, on the stump remnant of a fallen tree we saw a fine looking Fuligo septica.

Eight hours later and the peridium’s colour was fading and it had started to disintegrate.

Some other Fuligo septica aethalia we saw on the same day towards the end of the Woodland Trail.

And some Fuligo septica plasmodia.

A closeup of the bottom group in the above photo — you can see some plasmodial strands on the left clump.

As they are — these plasmodia — one could be uncertain as to what slime mould they are, especially the one below which could be mistaken for Mucilago crustacea, but based on what I’ve seen over the years, I’m certain they are Fuligo septica.
