18th November 2020, Oxleas Wood and Meadows

Went back to Oxleas but there wasn’t a great deal to see, maybe mid-November is getting a bit too late in the season.
A few highlights: Glad to see lots of Yellow Fieldcaps in the meadow, it’s nice to find a place where a species is abundant. Witches’ Butter is a new find for me. My book says this is thought to be common but very seldom recorded. Conocybe pilosella is new for me as well, though to be honest the id is very shaky. There’s lots of similar looking Conocybes and similar genera. The unidentified tiny, tiny mushroom (no.5 below) was a very exciting find, with a cap around 1mm across! The mycena genera contains many very small species but none of my books or any online resources mention anything with a proper mushroom shape and a 1mm cap, as far as I can see. Frosty Bonnet is pretty damn small but my beauties are significantly smaller than that! Pedicel Cup is one of many similar fungus species with a cup shape and fawn or brown colour – over 100 apparently, so can’t be sure of any identification. Don’t remember ever seeing one like this on a birch log before and Pedicel Cup is commonly found on beech and elm.  And lastly, Dog Vomit Slime Mould… I love finding slime mould – it’s a fascinating organism. I don’t find it very often. I expect there’s lots of it around but it just doesn’t gather into bodies very often. Also known as scrambled egg slime, or flowers of tan, and in Scandinavian folklore as troll cat vomit! Is it climbing the grass stems in order to hitch a ride or to spread its spores in the wind better?


1. Yellow Fieldcap (Bolbitius titubans).
Growing in grassy field. Lots scattered widely. Cap 0.5-3cm, stem 3-8cm. No smell. Sporeprint Brown. Spores 9.5-12.5µ x 7-8.5µ.

2. Unidentified.
Growing in grassy field. Only one. Cap 0.5cm, stem 3cm. No smell. Spores 5.5-7.5µ x 4.5-6µ.

3. Witches' Butter (Exidia glandulosa).
Growing on rotting hardwood log. A few blobby clusters. No smell. Floppy ear/cup structures, shiny on top, matt underneath, soft jelly-like. My book says this is thought to be common but very seldom recorded. Sporeprint White. Spores 12.5-16.5µ x 5.5-8µ.

4. Conocybe pilosella.
Growing in grassy/mossy field. One only. Cap 2.5cm, stem 4.5cm. Slight mushroom smell. ID is wild guess. Sporeprint Brown? - not enough to be sure. Spores 4.5-7µ x 3.5-5µ.

5. Unidentified.
Growing on mossy living(?) trunk of broad leaf tree. Several widely scattered. Cap 1-1.5mm, stem up to 4mm. Tiny, tiny, tiny! Spores 4.5-6µ x 3-4µ.

6. Spotted Toughshank (Collybia maculata).
Growing from leaf litter of oak. Many trooping in large group. Cap 3.5-10cm. Stem 5-10cm. Unpleasant smell. Sporeprint Cream. Spores 4.5-6µ x 3.5-4.5µ.

7. Pedicel Cup (Peziza micropus).
Growing on rotting birch log. Two. Lobe up to 6cm across. Fungus smell. Floppy lobes with slightly jagged edge. Hard to be sure this is exactly the correct id as there are several similar species and all have varying colours. ID is very likely. Sporeprint White(?) - not enough to be sure. Spores 14-16µ x 7-8µ.

8. Dog Vomit Slime Mould (Fuligo septica).
Growing on stems/blades of grass, or maybe just migrated there. Several blobby masses scattered widely. Around 2cm across. No smell. White or yellow on top with translucent jelly below.

6th November 2020, Beckenham Place Park

It is the fate of mushroom hunters to sometimes encounter things that they cannot identify, despite making every possible effort. Although I have many mushroom identification books, the one I use most is the Collins Fungi Guide (Buczacki) simply because it lists more species than any others, over 2400. But of course, it isn’t complete and doesn’t include many rare ones and foreign invaders. On this foray I found two specimens that I don’t recognise and can’t find in any of my books. One is a small innocuous looking single specimen growing from the end of a twig. It looks like Hydropus floccipes (which I’ve never encountered) but the spore shape is wrong. That has spherical spores whereas mine are elliptical or slightly bean shaped. I can’t find any other species with the right characteristics. The other species that I can’t identify is a small, nearly pure white one with a waxy look, growing in woodland. There’s quite a few mushrooms like that but none that I can find with spherical spiny spores. The main groups that have such spores are Brittlegill (Russula), Milkcap (Lactarius) and Deceiver (Laccaria). It’s nothing like the first two but does have the general appearance of a Deceiver, except that none of those are white.

Mycena mirata is another small Bonnet mushroom but new to me. The Suede Boletes were growing in a cluster which is very unusual for Boletes. Turkeytail is maybe the most common fungus in the country but this was an attractive rosette. Plicatura crispa is a very interesting find. This species has been confined to Scotland and the north but is apparently travelling southwards. Online I found just one record in the south, from East Susses and it’s definitely this species, as the underside with forked folds is unmistakable. Oakbug Milkcap is very common and I see it often. Pelargonium Brittlegill is a rather speculative identification as I only found one specimen and didn’t pay enough attention to details such as taste and how much the cap will peel. But it’s a nice pinkish little thing! Orange Mosscap I also see often. Redlead Roundhead is a striking orange mushroom that I haven’t seen before. It’s thought to have come from abroad and now is becoming more common in woodchip mulch environments like this.


1. Mycena mirata.
Growing on rotting stick of broad leaved tree. Small group. Cap 0.5-0.8cm. Stem 1.5cm. Looks a bit paler than usual for this species but still probably a correct id. ID is fairly likely. Sporeprint White. Spores 7-9µ x 5-7µ.

2. Suede Bolete (Boletus subtomentosus).
Growing in parkland near oak. Small cluster and group. Cap 2.5-7cm. Stem 4cm. Slight, odd, indistinct smell. Difficult to distinguish between some of the boletes in the Xerocomus family but this id seems most likely. ID is best guess. Sporeprint Brown. Spores 10-14µ x 3-5.5µ.

3. Turkeytail (Trametes versicolor).
Growing on exposed tree root. Two rosettes. Rosette 7cm across. Sweet mushroomy smell.

4. Unidentified.
Growing from the end of a fallen twig. One single mushroom. Cap 2cm. Stem 3.5cm. No smell. This looks like Hydropus floccipes but the spore shape is wrong. H. floccipes has spherical spores which these are not! Nothing else comes close to being being right, so could this be another Hydropus species which isn't in my books? Sporeprint White. Spores 7-9.5µ x 4-5.5µ.

5. Plicatura crispa.
Growing on large rotting branch. Many in large groups. Bracket up to 2cm wide. No smell. This species has been confined to Scotland and the north but is apparently travelling southwards. Online I found one record in the south, from East Susses. It's definitely a correct id, as the underside with forked folds is unmistakable.

6. Oakbug Milkcap (Lactarius quietus).
Growing from earth amongst bracken near oak trees. Many scattered around singly. Cap 3.5-4.5cm. Stem 3.5-5cm. Slight indistinct musty smell. Milk mild and slightly nutty. ID is almost sure. Sporeprint White. Spores 6.5-8.5µ x 5.5-7.5µ.

7. Pelargonium Brittlegill (Russula pelargonia).
Growing on earth amongst bracken near oak trees. Just one. Cap 4cm. Stem 4cm. Fruity smell. Rather waterlogged, which may have washed out the colour. Speculative identification since it's hard to pinpoint with just one specimen. ID is possible.

8. Unidentified.
Growing in leaf litter near oak trees. Small group. Cap up to 2.5cm. Slight sweet smell. This is a mystery. There are several white mushroom species that look like this but none of them have the spiny round spores of these. The main groups that have such spores are Brittlegill (Russula), Milkcap (Lactarius) and Deceiver (Laccaria). It's nothing like the first two but does have the general appearance of a Deceiver except that none of the Deceivers are white?? Sporeprint White. Spores 6.5-8.5µ x 5.5-8µ.

9. Orange Mosscap (Rickenella fibula).
Growing in moss in grassy field. Many scattered around in the mossy patches. Cap up to 1cm. Stem up to 1.2cm. No smell. Sporeprint White. Spores 4.5-6.5µ x 2.5-4µ.

10. Redlead Roundhead (Leratiomyces ceres).
Growing in woodchip mulch. Several scattered in group. Cap 1.2-3cm. Stem up to 3cm. Faint indistinct smell. Sporeprint Purple brown. Spores 7.5-9.5µ x 6-7.5µ.
