This is a first for Abney Park. I am indebted to Dr. Martyn Ainsworth from Kew for identifying it and for the considerable effort he took. It grew last November (2011) and it is tricky. It looks like P. conopilus when it is young with a leathy brown cap, but it expands to a different shape. The end colour of the cap is buff with a reddish brown center. The microscopic details are given in my notes.

This is shown in my books as being on conifer wood so it was surprising to find it on a barkless hardwood branch. This is what it looks like, though. The microscopic examination shows the spores occasioinally bud small rounded structures, which this one did, and that is only found in viscosa. The macroscopic coral type branching is not overly developed here, but it is more then the occasional bifurcation of the tips of the more usual C. cornea.

This was a cap that Tony found on some very rotten wood on the Wander. It was gorgeous. When young it is a golden yellow, as its name suggests. With age it reddens and then browns. This pair of caps had got as far as the reddening stage but not all over. The cap surface had split slightly showing the under flesh, a light crackle roughly radially over the vivid surface. The yellow stem had reddened too, though this is not referred to in my books. The stem base was white-ish and sligthly broader.

The best place to begin is with a species list…..

1. Auricularia auricula-judae,  Jelly Ear.

2. Xylaria hypoxylon, Candlesnuff or Stag’s Horn Fungus.

3. Clitocybe nebularis, Cloudy Agaric.

4. Lepista nuda, Wood Blewitt.

5. Parasola conopilus, (was Psathyrella conopilea).

6. Chlorophyllum rhacodes.

7. Hebaloma crustuliniforme, Poison Pie.

8. Tubaria sps.

9. Calocera cornea, Small Stagshorn.

10. Cortinarius decipiens.

11. Bjerkandera adusta, Smoky Bracket.

12. Rigidoporus ulmarius.

13. Byssomerulius corium, Netted Crust.

14. Lepista saeva, Field Blewitt.

15. Agaricus xanthodermus, Yellow Stainer.

16. Clitocybe candicans.

17. Psathyrella multipedata, Clustered Brittlestem.

18. Ganoderma australe, Southern Bracket.

19. Mycena galopus, Milking Bonnet.

20. Psathyrella microrhiza, Rootlet Brittlestem.

21. C0prinellus micaceus, Glistening Inkcap.

22. Agrocybe cylindracea, Poplar Field Cap.

23. Ganoderma applanatum, Artist’s Bracket.

24. Perenniporia fraxinia.

25. Flammulina velutipes, Velvet Shank.

26. Pluteus chrysophaeus, Yellow Shield.

This was one section of the fungus around at the time. The debates and discussions enlightened and slowed progress. A really good day.

These caps were growing on 24.11.2011. Small, neat caps, towards hemispherical in shape and then flatter and  tending towards having a scalloped edge. The central stem was straight and the base had a ridge around the stem and a swelling below the ridge. The colour was cream, but then it was dry. If it had been damper it would have been a reddish brown. Growing on deciduous stumps of dead wood etc.

Hi there,

This year the trust hasn’t booked an expert to lead a fungal walk, so a do it yourself wander round is planned. It has been a really bad season so far, but in the last week more variety of fungus has been growing. I am hoping that this continues to be the case for the next week. There will not be a leader, it is more going round with others who may know a bit more then you. I’ll try to plot a route to take in the more interesting fungi. Bring Field Guides, hand lens, anything you have that helps to identify what might be there. We will begin at 10.30am at the front gate.

If you would like to see what there could be growing, recent growths are on the end of Fungi and slime molds 2011. Abney is deeply into Autumn. Recent photos of Abney are on Photos of Abney Park Cemetery November 2011.

Psathyrella prona

There are several versions of P. prona. Psathyrrella prona f. cana and prona f. orbitarum are out there somewhere, but not very often. P. prona is widespread but rarely reported. What I found was a dried cap, which had dried when the cap was young and still in a hemispherical shape. The gills then matured. I picked a white cap and turned it over to find apparently black gills with a striking white edge underlined with red. All the keys I have lead to prona, and there is nothing to disagree with that conclusion. It has been suggested before as being in Abney, but a field ID just didn’t seem quite enough.

This has been suggested as being in Abney before, but I haven’t been convinced up until now. It needs microscopic examination to really pin it down. It is probably not new to Abney, but it is newly pinned down as being this species so added to the lists. It has taken me a while to work out what it is. The very young cap I looked at didn’t have the red edge to the gills that the slightly older caps have. The pleurocystidia (large cells on the gill surface) occasionally divide into two points. I found 2 spored basidia in the young cap and 4 spored later on, and a mix of 2 and 4 spored basidia is in the books. The photos are not great at defining what it is. The young caps were very bright and colourful, it was only the more mature caps that began to look as the species is supposed to look.

A single brown cap, in not the best of conditions, is not a conclusive or ideal way to come across what I think to be a new species for Abney. It is, though, previously undescribed for the cemetery, and I think enough information is there to claim this as the species.

It is brown, a rich deep colour that is described as red/brown, chestnut/brown or purple/brown in Funga Nordica. The gills are the right colour and are roughly of the right spacing; the spores are the right size and their shape seems so variable in the book that the found spores fit into the description; the shape and size of the cap is about right, the habitiat is OK; the stem the right size and colour; the gill cystidia are about right, I could only see the tops of the cystidia, but there was nothing there to say it wasn’t P. bipellis; there were hairs over the cap, and this equates to hair like veil cells; it grew on the edge of woodchips, which is about right, as bipellis grows on buried wood.

The smell of the collected cap was distinctly of cat’s urine. I know this smell, I have a cat. In the Fungi of Switzerland, where it is still called P. odorata, it is described as smelling of cats urine somtimes. This is not refered to in Funga Nordica.

My problem with pinning it to this species is that it is only known in a handful of places in Britain. It is rare, and claiming a rare species from one cap that is not in the best of condition is always going to be a bit dodgy. I shall still go ahead, and await the email from someone who knows better telling me otherwise. So here it is.

Hooray, hooay, the mushrooms are beginning to grow again. There were a couple of hundred caps trooping across one area of woodchip a couple of days ago. Parasola conopilus, (which is in all my books still as Psathyrella conopilus), can grow in very small groups or even one cap by itself, but given the chance does put on a good display. The stems almost make a point of being upright. The caps are a leathery red/brown when wet, and dry out to almost white. When they are young the colour is redder and more intense. A hand lens examination of the gills shows them to have a white edge.
