Members’ Finds, July to December 2024

Following the success of our Members' Finds project introduced in 2020, here is our new page for July to December 2024 to which members are again invited to contribute. Please email Penny photos of anything you find - even of species already on previous lists. Common or rare: all are welcome! Thanks to all our many contributors, we now have well over 1000 species illustrated here, all from Buckinghamshire!

• Aim to show all aspects of the fruitbody even if this necessitates several photos.

• Please send images as an attachment and not embedded into the email text.

All photos should be captioned with fungus name if known, site, date, your initials. EG Amanita muscaria Penn Wood 01.10.2024 PC1.

• Please include in your email as much detail as possible (eg size, smell, substrate, habitat, microscopic details if available). All clues are vital when identifying solely from photos.

• If possible collect and retain at least one specimen until you've heard back from Penny in case further investigation is required - records of rarities are invalid without voucher material which may well need to be dried for molecular sequencing to confirm.

NEW FOR 2024! Click on Previous finds at the end of any entry to view all other Members' Finds entries for that species.

NEW FOR 2024! We now have a SEARCH FACILITY for the LATIN MASTERLIST INDEX, speeding up access and automatically grouping all entries for any one species together for convenient comparison etc.

• The regularly updated list of entries remains in place as previously, in a choice of either Latin binomial or English common names.

microscope Only entries marked with this symbol have been microscopically examined. There is no guarantee on identifications made of entries lacking this symbol though all photos are checked and selected by Penny to the best of her ability. Basic accompanying notes are also Penny's.

HAPPY HUNTING!

Agrocybe rivulosa  by Jim Wills Agrocybe rivulosa  by Jim Wills Agrocybe rivulosa  by Jim Wills July 13th Agrocybe rivulosa (Wrinkled Fieldcap) microscope

On a path covered in old woodchips in Austenwood, Chalfont St. Peter, Jim Wills spotted several clumps of mushrooms obviously triggered into action after the recent rains. Described as an alien species which arrived here 20 years ago, probably on imported woodchip, it has spread rapidly and is now relatively common, favouring well rotted woodchip piles. Typical of the genus it has a pale cap not unlike Agaricus, fruits mainly in summer, has deep brown spores and a marked ring on the stem which hangs down (pendant - see photo 3). The cap soon develops deep wrinkles or fissures (see photo 2). Similar is Cyclocybe cylindracea - previously in Agrocybe and also found on woodchip. They can be separated by smell - farinaceous in today's species but aromatic in C. cylindracea, also with microscopy - the spores of today's species having a notably larger germ pore.

Polyporus tuberaster  by Chris Grimbly Polyporus tuberaster  by Chris Grimbly July 5th Polyporus tuberaster (Tuberous Polypore)

In Bernwood Forest Chris Grimbly noticed this quite distinctive Polypore with cap similar to a smaller version of P. squamosum (Dryad's Saddle) with very widely spaced pores underneath which appear slightly decurrent. Not surprisingly the cap is somewhat nibbled – woodland fungi favoured my small mammals are in short supply at the moment so are very likely to be gratefully munched at any opportunity! Though by no means rare this appears to be a new entry for Finds.

Melanogaster ambiguus  by Jesper Launder July 1st Melanogaster ambiguus (Stinking Slime Truffle) microscope

In Beaconsfield Jesper Launder went searching for truffle 'dig holes' in a spot under Lime and Oak where he'd had success a few weeks back. Finding one with some truffly scraps he investigated more closely and was instantly hit by the most repellent vile smell he described as of landfill gases! The remains of the specimen were not in the best condition (obviously fully mature!) and were black and sticky within. He knew at this moment it had to be M. ambiguus but bothered to check the spores later at home to confirm. We have just two previous county records from 2007 found not far way in H. Wycombe and Jesper says he's only found it previously in a Manchester park.
