The background information is all in the image. This is the second British record - see: http://www.fieldmycology.net/FRDBI/FRDB ... BNum=62627. More about the species here (Paul Cannon has updated the info based on this collection): http://fungi.myspecies.info/all-fungi/o ... s-ponticus

cheers

This was spotted about the 14th April by my sister-in-law, growing in last years tomato 'gro-bags' in her greenhouse. She'd pulled them up as 'buttons' and to me the buff-ochre caps looked like an Agaricus or maybe Calocybe gambosa. The gills were whitish but there was no mealy smell.
With a little encouragement in a moist environment they expanded to 50mm (see attached images).
The gill edge was clearly fimbriate: the lecythiform cystidia and spore colour pointed to Conocybe and with that stout structure it could only be Conocybe intrusa ! Spore shape & size confirm the ID. First time I've seen this.

Sorry, Roy. I had to restore from a backup so your images will need to be uploaded again.

Adam,
I have gone into 'edit post' and loaded the 3 Conocybe images again. For info:I had issues the first time and had to load each image separately. I had to do the same for the second uploading also. My screen is showing 3 images and 2 'blanks'.

Interesting Chris
not being a lichenologist I wasn't (to my shame) aware how frequent the host is: https://species.nbnatlas.org/species/NBNSYS0000018579 . . . . I shall keep an eye out for these Vouauxiella spp. (once I've learnt to recognise the Lecanora :oops: )

Each taxon on an island is more finite than elsewhere so encourages a wider perspective. Our small recording group look at a range of taxa and feed off one another. The plus side is a better understanding of the environment ... but one will never develop a vast knowledge within an individual taxon such as yourself.

Regards, Chris

Sphaerellothecium minutum.

Smith, et alThe Lichens of Great Britain and Ireland note: 'The most common lichenicolous fungus on S. fragilis is the small ‘pyromycete’ Sphaerellothecium minutum Hafellner ..."
I'm grateful to Paul Cannon who advised it was what I have, told me what to look for, and provided literature. He will be credited with the identification. A sample has gone to Kew. Apparently the third British record.

After such a long and hot dry spell I was surprised to see this growing out of an old railway sleeper around a raised flower bed. The dark gill edge confused me at first but it gave a pink spore print and it turned out to be Pluteus atromarginatus, one I haven't seen before. The cap is around 5cm, it has horned pleurocystidia and no cystidia on the gill edge.

Only just caught up with this one. I would recommend popping this on ASCOfrance. Alain Gardiennet is producing an impressive resource of lichenicolous fungi there. Four species of Sphaerellothecium on that site, but not yours. PLus those are good quality images.

Will do Chris, in due course. Struggling with shingles at present and have little energy. Still have a few to load on our own website.
