Parasitic fungus found on Xylaria hypoxylon

[FungiJohn]

After finding Longshaw still deep under snow, Nettle Runner Les and I visited the Upper Derwent Valley in Derbyshire. It turned out to be another good day with some interesting species.

As usual there were a few odd ones, including several Xylaria hypoxylon with a parasitic fungus attached.



Closer up:



Has anyone come across this one?

Comments much appreciated.

hi both

some posts back we has the 'parasite' of another xylariaceous fungus - an Hypoxylon I think - which turned out to be the conidial (imperfect stage)

that shouldn't be the case here as the conidia are forming the white tip of the fruitbody; with some distinctive exceptions these 'fungi on fungi' can be very tricky and often unidentifiable without getting them into culture

Ellis and Ellis 2 might help - though I suspect that this one wont be awash with characters

that's the (pitiful) best I can do

Many thanks Chris. It's a good start in a very difficult area. I'll have a look in Ellis & Ellis

After much reading and help from many others it's possibly Calcarisporium arbuscula on Xylaria hypoxylon.

Calcarisporium arbuscula

hi John

that is quite possible - obviously it's a microscope job - Calcarisporium was one of the possibles I suggested in that previous post I referred to above . . . as I was so patently wrong then, I was keeping my powder dry (no pun intended)

cheers

Hi Chris

Keeping my powder dry too

I've sought a few friends help including our good friend Mykonik with this one!

I found very little 'microscopic' information re Calcarisporium arbuscula but the 'gist' and available data appear to point there.

Oh, roll on the start of Basidiomycota

wash your mouth out John!!!!!! - if ever there was a group of fungi bereft of decent characters, where one is reduced to deciding whether something is 'brownish-grey' or 'greyish brown' it was the Basidio's

just because they're big and everyone notices them
I do of course excuse the 'honorary' Basidio's the rusts and smuts (which I love with a passion)

let's hear it for the asco's, zygo's, hypho's and coelo's !!! ........................................ silence ................................ tumbleweed .............................. I thought so

I know what I like

tee eee

Hear it too for those truly photogenic Myxomycetes. Not true fungi but always interesting species.

… and I like what I know, getting deeper in the forest, getting fungi as they grow ...

Sorry, I had a quick flash back to early Genesis

Came across these today and knew they reminded me of something I'd seen on here.
