Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

two opinions in one minute, two different genera. I must say looking at google images, the first det seems to be the best option. Any idea how many species of these genera in Britain.

The sporangia are stalked

The sporangia are stalked which rules out Tubifera where they emerge directly from the hypothallus.

There are about a dozen UK Stemonitis. I've no idea how you'd get to species from these images - the genus key in Ing's handbook starts with the surface structure of the spores. (To my untrained eye, others such as S. axifera look just as likely.)

We are surrounded by Davids!!! Dioctria you are right with the vast majority of Myxos they cannot be taken to species without microscope work and often it is difficult even then and the picture does not show the reticulations on the spores to prove S fusca;)

Dave & David Tubifera is

Dave & David
Tubifera is described as closely appressed cylindrical sporangia (so far so good) resting on a thick spongy hypothallus OOps so no stalk.
There are about 20 species of Stemonitis but that is without counting the 12 Stemonitopsis and the other 13 genera in the Stemonitales falmily.

Nope, not Tubifera...

I absolutely agree - once I posted this and saw Stemonitis having been mentioned, I could see that genus was correct (with the stalk an' all), though I don't know about the species. Slowly and painfully learning this group via Ing's book...

if i correctly interpret comment from flaxton, this one can only be certainly identified to family Stemonitales? Or can we be confident of genus Stemonitis?
