L. umbrinum

Hi All,
I have not had a moment to spare for MO and correcting all the ID issues on this group. I will get there, PROMISE!
I will be talking at SOMA camp next weekend on the Gasteromycetes.
In general…..L umbrinum is smoother like L pyriforme, and dark like L nigrescens. L nigrescens has the spines and reticualte pattern like L perlatum.
Confused yet?

Last night I switched the tag from foetidium to nigrescens, after reading these comments and looking on mykoweb I think I’ll put the umbrinum tag on it today.

I don’t think this is Lycoperdon nigrescens. The sporocarps lack the prominent spines as seen in the european books (see British Puffball, Earthstars and Stinkhorns)and as mentioned Irene. It probably is in the L. umbrinum group which lacks spinose exoperidium. See michael Woods comments on Mycoweb on nigrescens-umbrinum. L. nigrescens is not very common in the west and I think L. umbrinum is under reported. this group need lots of work.

Different books lead to different IDs..

But I think we have a pretty good consensus about Lycoperdon nigrescens now (at least in Europe). It’s a species that reminds of Lycoperdon perlatum (after the spines/warts have fallen off, a netlike pattern of small granules remains on the surface). The L. nigrescens I usually find are a bit smaller, with a shorter stalk (or almost none), young fruitbodies sordid white, but with a darker/darkening exoperidium and spines (light to dark brown). The net surrounding the spines is more wooly than granulate in nigrescens.

I wonder if it’s foetidum as a synonym that has caused confusion and made it(foetidum/nigrescens) interpreted in different ways. Lycoperdon foetidum is a species described by Bonorden, a not very detailed description where he also wrote that he had only seen it once (with a smell like Scleroderma). I can’t say I’d be able to ID a puffball from this (translated): “Thin, soft, head-shaped, thinned downwards, yellowish-blackish brown in youth, with equally colored sharp, triangular spines.”
Any areolate net is not mentioned here, but is when he describes another species, so I’m not convinced that his foetidum is the same as what we now call nigrescens.
It would have been very interesting to hear the stories behind the synonyms and interpretations of these species.

I read MD and when I was done I wasn’t sure what the difference is.

Probably…

People aren’t really sure of the difference?

I wonder why

almost every Lycoperdon nigrescens here on MO look like Lycoperdon umbrinum?

yes

I emailed her about these 5 minutes ago.

Did someone check with Stephanie about these?

Someone should check with Stephanie, does she have some good samples of these yet?
