Acrospermum compressum or pallidulum or both

Dragiša Savic, 24-04-2015 14:49

I found it on Galium mollugo, about 1mm tall, does anyone have the key to this genus?

Re : Acrospermum compressum or pallidulum or both

Hi Dragiša
I can see why you might be confused with the host being a Galium species, but for me this is Acrospermum compressum. I know both species quite well and pallidulum is - as its name suggests - a very small and pale (and softer in texture) fungus. Here in the UK A. pallidulum is virtually restricted to Cruciata laevipes and grasses (often those in close proximity to the Cruciata).

I'm afraid I don't know of a key to the genus.

best wishes
Chris

Thank Crhris, the experience is better than the best key.

Re : Acrospermum compressum or pallidulum or both

Hi,

when Minter et al. introduced the order Acrospermales, they refered to a key in the Dictionary of the fungi 8th ed. ( http://www.scielo.org.ar/scielo.php?pid=S1851-23722007000100013&script=sci_arttext )
I have only access to the 9th and 10th ed. where I can't find this.
Does anyone have this and check if it goes beyond order level?

Regards
Martin

Thanks Francis!

So no key beyond family level...

Re : Acrospermum compressum or pallidulum or both

I think that today I found A.pallidulum on Cruciata laevipes. Still do not have a micro.
