Castle bottom foray

[CapAndBracket]

I'm hopeing someone will agree these are Delicatula integrella, found today on the side of a wheel rut while foraying with cybershot, their spores
are listed as hyaline but not sure this is a good enough reason for my not
finding any.

Cheers J.P.

tiny, white and almost translucent, these were not an easy subject to capture




JP was good at turning up small white fungi today

[cybershot]

This little beauty is hopefully shedding some spores on a slide for JP to undertake further investigations but comparisons with the aid of C&D indicate the possibility of a Psathyrella species. 3cm cap on a large old conifer stump showing white fibrils (JP should know gill colour and any gill edge characteristics by now). Stem white with cortina.

Psathyrella chrondoderma perhaps, but will need microscopy?

Perhaps you were just about to check that suggestion in the Checklist David. I assume so, but here's the information:

"Psathyrella chondroderma

Habitat: On conifer wood, usually on large stumps.

Notes: Described from Scotland (Glamis) and collected since then in Wester Ross, but very poorly known in Britain."

You might like to start with something more common, such as Psathyrella piluliformis.

Also, having read AlanS's recent very helpful posting on little white species of Lachnum, I'd be surprised if your photo shows Lachnum virgineum because the hairs around the edge are not clear in the photo.

Without microscopy I wouldn't really know where to start with your little white mycenoid species.

PS The spores of Psathyrella piluliformis are a dead giveaway because they are tiny for that genus.

PPS And the currently linked photo of Lachnum virgineum in the A-Z is the one AlanS said did not look like that species because the hairs are too short.

[Fungus Ken]

Just occurred to me that I should follow my own counsel and consult the Basidiomycota Checklist on my own suggestions.

Psathyrella piluliformis, according to the Checklist, grows on decidious wood. There is no mention of this species on coniferous wood.

But I'd still suggest looking at the more common species - and hence more likley species - first rather than plumping for a species that has never been recorded in England.

Psathyrella piluliformis, juvenile.



The info kept dragging me back to this species,
much to my suprise it hadn't dropped any spores over night,
but what i could see under scope were small, just having a
bad time with microscopy as i was trying to be clever and
get good image of cystidia for certain ID, the congo red seemed
to merge all features and cotton blue showed they were definately
thin walled and hyaline (but hard to pick out) amazing how species
vary in extent of being agreeable (feeling like a real novice at the
moment) ho hum

The white cups had no hairs and at best i imagine they are among
the Hymenoscyphus species, they were on pine in wet ground, i
imagine the acidity was quite high (pH low number).

Cheers J.P.

Makes good sense Ken and I may well have erred with the wood type. Also JP seems to have pinned it down further.

Hi JP - this is a species of Hemimycena and (from the distinctive cap shape, probably H. cucullata).

Certainly isn't Delicatula integrella !

As ever many thank's, you da man.

Cheers J.P.

Another Psathyrella species from the same foray this time the cap is faintly striate towards the margins
