Members’ Finds, 2021

Following the success and popularity of our experimental Members' Finds Autumn 2020 project, we have now set up this new page for 2021 to which members are again invited to contribute. We are starting afresh with a new species list, so please email Penny photos of anything you find - even of species previously on last autumn's list. Try to illustrate all aspects of the fruit body, also remember not to reduce the photo size and to include the date, site, substrate, habitat plus any other useful features such a size, smell, etc. All extra clues are vital when identifying solely from photos. Ideally, try to collect at least one specimen and retain in a pot until you've heard back from Penny in case it might be needed for further investigation - records of rarities are of no use without voucher material as we discovered to our cost in several instances during our autumn project.

As Covid 19 Tier 4 restrictions (January 2021) require only essential travel in our area, we will all now be limited to our local patches. Therefore as Penny and Derek both live outside the county they will not now be able to contribute until the restrictions are eased. So it will be up to members to take on the challenge and keep the records coming in!


As before, please bear in mind that only collections having the scope symbol have been fully examined in order to make a determination. No guarantee can therefore be given on the vast majority of identifications though all photos are checked and selected by Penny to the best of her ability. Basic accompanying notes are also Penny's but when of a species already covered in Members' Finds Autumn 2020 a reference to the appropriate date will be given rather than duplicating the identification tips here.

If and when numbers demand, we will include here a list of Latin / English names to facilitate the location of a particular species.

Image Details
Tremella mesenterica  by Joanna Dodsworth Tremella mesenterica  by Claire Williams January 14th Tremella mesenterica (Yellow Brain)

This species was spotted by Joanna Dodsworth on a pile of deciduous sticks in Brill Common (photo 1) and also by Claire Williams the following day on an Oak stick in Downley Common (photo 2). (See also Members Finds Oct 30th.) Jelly fungi seem to be unhindered by the winter weather: we have examples of several species found in the last couple of weeks.
Trametes gibbosa  by Joanna Dodsworth January 14th Trametes gibbosa (Lumpy Bracket)

Joanna Dodsworth noticed these brackets on fallen Horse Chestnut in Brill Common. Typical of this common species is the green algae growing on the upper surface and the maze-like almost semi-gills on the underside - both features visible in the photo. (See also Finds 2020 dated Sept 20th.)

January 12th 2021

Neodasyscyphus cerina Latin by Barry Webb January 12th Neodasyscyphus cerina (a cup fungus with no common name)

Barry Webb found these tiny little stalkless cups on fallen Beech in Burnham Beeches. The identification has been made simply from their appearance in the photograph where the distinctive bright yellow centres and contrasting hairy outer surface seem diagnostic, also though we have no other county record of this species it is apparently quite common on Beech. Barry suggested the common name Lemon Tarts!
Polyporus brumalis  by Barry Webb January 12th Polyporus brumalis (Winter Polypore)

Barry Webb found this fungus on fallen Beech in Burnham Beeches. At first glance not unalike a species of Pluteus or other brown-capped mushroom, it is not until one looks underneath and notices not gills but pores that the genus becomes obvious. One of several quite common species of Polypore, this is quite evenly brown, has widely spaced pores and is aptly named - often fruiting late in the season.
Scutellinia scutellata  by Barry Webb Scutellinia scutellata  by Barry Webb January 12th Scutellinia scutellata (Eyelash Fungus) with Metatrichia floriformis (a slime mould with no common name)

Barry Webb found these two species growing together on rotting bare wood in Burnham Beeches. Though not checked with a scope, the Eyelash Fungus is likely to be this particular species which has by far the longest eyelashes in the genus. The tiny stalked black slime mould specimens are at the stage just prior to splitting open to reveal the spore mass within. (See more images in Finds 2020: Scutellinia dated Sept 28th and Oct 1st, Metatrichia dated dated Oct 17.)

January 11th 2021

Hyphodontia sambuci  by Joanna Dodsworth January 11th Hyphodontia sambuci (Elder Whitewash)

On part of Brill Common Joanna Dodsworth noticed this good example of one of the commonest corticioid fungi (those which are flat, don't form brackets, and often look like splodges of white paint on fallen wood). The genus Hyphodontia is large and nearly always needs a scope to identify to species but this aptly named species is so common on Elder - both living or fallen as here - that one can safely name it in the field though it does occur on other deciduous woods as well.

January 10th 2021

Tubaria furfuracea  by Barry Webb Tubaria furfuracea  by Barry Webb January 10th Tubaria furfuracea (Scurfy Twiglet)

Barry Webb found these small mushrooms fruiting on deciduous wood in Burnham Beeches. This species is a very common LBJ and often mistaken for a species of Galerina or Conocybe - both genera very similar in size and colour of caps and gills. Look for the remnants of white veil near the cap margin (seen in photo 1), the often slightly decurrent gills (though not in this case!), the white veil flecks on the stem as well, the even colour over the whole fruit body and its often clustered habit - sometimes in very large numbers - in woody litter. (For another example see Finds 2020 dated Oct 3rd.)

January 8th 2021

Exidiopsis effusa by Claire Williams January 8th Exidiopsis effusa (HAIR ICE!)

Claire Williams has found a beautiful example of a rare sight known as Hair Ice (also Ice Wool / Frost Beard) in Lane End. It is only in recent years that the fungus responsible for this phenomenon, a 'Jelly fungus' called Exidiopsis effusa, has been identified and these amazing ice crystals only form on wood affected by this fungus in really moist icy conditions - exactly what we have been experiencing recently! To learn more about this fascinating process there is lots of information online including several videos on 'YouTube' which are well worth seeing!
Flammulina velutipes  by Claire Williams Flammulina velutipes  by Claire Williams Flammulina velutipes  by Claire Williams January 8th Flammulina velutipes (Velvet Shank)

We already have one image of this common winter mushroom but of older rather dark specimens. Today's photos, taken by Claire Williams in Downley Common Wood, are of young and fresh though frozen material which is considerably paler than our previous image. The stem, often much darker and finely velvety towards the base than shown here, can start off much paler all over, but still visible here (if you can zoom in on photo 3) are the tiny hairs - some of them considerably darker than the general stem colour.
Panellus stipticus  by Claire Williams Panellus stipticus  by Claire Williams January 8th Panellus stipticus (Bitter Oysterling)

In Downley Common Woods today Claire Williams found amongst quite a few other fungal species (not all of which could be identified thus are not included here) this nice cluster. It is clearly surviving the frosty conditions quite happily on this moss covered deciduous log, and the underside view shown here leaves one in no doubt as to its identity though just from the top view this would not be possible. (See also Oct 3rd in Finds 2020 for more info.)
Mensularia radiata  by Claire Williams Mensularia radiata  by Claire Williams Mensularia radiata  by Claire Williams January 8th Mensularia radiata (Alder Bracket)

Claire Williams found several deciduous trunks liberally covered in these brackets in Downley Common Woods. Recently moved to its present genus from the better known Inonotus, this bracket is deceptively named and is just as likely to occur on other deciduous trees as on Alder. The trees here could not be identified but if anyone recognises the bark do please let Penny know.
Auricularia auricula-judae  by Claire Williams January 8th Auricularia auricula-judae (Jelly Ear)

Claire Williams noticed these small and somewhat frozen fruit bodies on an unidentified branch in Downley Common Woods (probably Elder but it could be some other tree?). (See also Sept 30th and Oct 25th in Finds 2020 for more info.) It seems that Jelly fungi are quite happy fruiting in this cold spell of winter weather.

January 6th 2021

Exidia glandulosa  by Paul Goby January 6th Exidia glandulosa (Witches' Butter)

In Naphill today Paul Goby found these black 'shiny firm wrinkled blobs' - his description! They were growing on a bare dead trunk - likely to be Oak on which this genus is probably most often found though it can occur on other deciduous wood and at any time of year given damp enough conditions. It is another of the 'Jelly fungi' belonging to the Basidiomycetes despite often appearing very similar to the Ascomycete Bulgaria pura. See also under Oct 24th in Finds 2020.
Trametes versicolor  by Greg Douglas Trametes versicolor  by Penny Cullington January 6th Trametes versicolor (Turkeytail)

Greg Douglas spotted this nice collection on an unidentified deciduous log in Captain's Wood, Chesham. A common but often impressive bracket when in good numbers, it can be found on fallen wood of many kinds at most times of year. (See also Finds 2020 dated Sept 26th). Look for the white finely pored underside and clear zoning on the top surface which certainly recalls the shape and colours of our Christmas dinner bird's tail!
Flammulina velutipes  by Penny Cullington January 6th Flammulina velutipes (Velvet Shank)

On Joanna Dodsworth's walk around Brill she found this impressive clump on a standing dead Willow trunk. This is a species often fruiting during winter and can often be found even in snowy conditions. The caps are often considerably paler and yellower than shown here but the features to note in the field are its tightly clustered habit on deciduous wood (often standing) and the finely hairy stem which becomes darker to black towards the base. Penny was surprised we had only one collection of this in Finds 2020 (dated Oct 26th), so it's clearly one to be looking out for now.
Byssomerulius corium  by Joanna Dodsworth January 6th Byssomerulius corium (Netted Crust)

On Joanna Dodsworth's walk around Brill she noticed this common corticioid species covering a deciduous stick. It has a somewhat leathery consistency and is quite easy to peel off the substrate - a feature which helps to separate it from the many other similar flattish white resupinate species. It can be found at any time of year but as it happens is not one we included in Finds 2020.

January 3rd 2021

Myxarium nucleatum  by Russell Ness January 3rd Myxarium nucleatum (previously Exidia nucleata) (Crystal Brain)

Russell Ness noticed these small white lumps of jelly on deciduous wood near Dorney. This is quite a common Basidiomycete, one of the 'Jelly fungi' and often found on Beech logs though here on unidentified wood. For more notes see Finds 2020 dated Nov 5th though under its previous and much more familiar name there.
Diatrype stigma  by Russell Ness Diatrype stigma  by Russell Ness January 3rd Diatrype stigma (Common Tarcrust)

Russell Ness found this species of Pyrenomycete (i.e. a crusty black Ascomycete) on an unidentified deciduous fallen branch near Dorney Reach. Commonly occurring in large smooth patches on fallen Beech trunks, it is less usual on other deciduous wood as here (there was apparently no Beech in the area). This was not a species we included in Finds 2020 - not because it wasn't seen but probably because we were spoilt for choice with so much else to catch the eye.
Pleurotus ostreatus  by Russell Ness January 3rd Pleurotus ostreatus (Oyster Mushroom)

Russell Ness found this fresh and healthy collection on a fallen deciduous trunk near Dorney Reach. He can vouch for the freshness because apparently it tasted delicious in his beef stir-fry! For further images see Finds 2020 dated Sept 21st, Oct 27th and Nov 17th, proving that this is a species which can be found at any time given the right conditions and substrate.

January 1st 2021

Gliophorus psittacinus  by Penny Cullington January 1st Gliophorus psittacinus (previously Hygrocybe psittacina) (Parrot Waxcap)

On his daily walk around Prestwood Tony Marshall noticed these fresh but frosted specimens but had no camera at the time! Returning the next day for the photo he found them thawed but now very faded, as often happens when Waxcaps are frosted - they're colours can change radically adding to the difficulty of identification. See also photos and notes from Members' Autumn Finds 2020 dated October 3rd and November 1st.
