Felbrigg Hall Estate Slime Moulds & Fungi – August 2023

6 August 2023

Near the entrance from the car park we saw a gregarious group of probable Agaricus arvensis — the horse mushroom. I find the gills more fascinating than the cap.

In the grassland to the south of the Hall a cluster of unidentified mushrooms in the grass with a distinctive wavy skirt-like edge.

Mucilago crustacea — the so called “dog sick” slime mould in the grass.

Mucilago is a monotypic genus with Mucilago crustacea the only species in the genus.

In an area of sweet chestnut trees we came across large groupings of Marasmius rotula — the collared parachute mushroom.

Felbrigg Hall – 4th August 2023

This mushroom looks similar to Gymnopus androsaceus — the horsehair parachute mushroom but M. rotula can be distinguished from G. androsaceus by it’s gills being attached to a collar around the stem rather than to the stem as with G. androsaceus.

In the photo below the bent over mushroom on the left can be seen with a collar around the stem.

Another slime mould — growing on leaf litter.
Not certain that it’s Mucilago crustacea — it has a Stemonitis look about it.

Near Lion’s Mouth lane we spotted more Fuligo which the daughter reckoned to be Fuligo cinerea. I’m not so sure myself as — to be certain — one would have to determine the spore size.

F. cinerea has spores that are over 10 µm in diameter whereas F. septica’s spores are 6–9 µm. But F. septica aethalia are often very large and F. cinerea small or medium. [1]

Is this aethalia large, medium or small?
