A trip to Necarne Castle in Co. Fermanagh.
High pressure, but dull.
At first I thought this little group of Mycena pura was some kind of mushroom with hairs.
On closer inspection, I saw that the 'hairs' were actually another tiny fungus - Spinellus fusiger - parasitic on the Mycena.
The right hand image shows the tiny parasitic fungi. They're about 3mm. long.
This brown/green gelatinous mass is Nostoc commune. - a cyanobacterium....highly prized in some countries as a delicacy.
Specimen shown about 6 cm. across.
I initially thought this was a Wood Mushroom, which is edible. But on cutting the stem it immediately went bright yellow at the base, so that makes it the Yellow Stainer - Agaricus xanthodermus, which is poisonous.
