Arum maculatum: a full set

So I went out today in the hope of finding several of the microfungi associated with Ficaria verna given the excellent information posted by Chris last year and everybody else's finds. Unfortunately, I managed only Uromyces dactylidis. However, I did manage what I think is a full set for Arum macula...

Re: Ingoldian Fungi

Chris

Could you give a few more details of the collecting method please. Do you just scoop the foam into a container and add some fixative. Then examine straight away under the microscope? How much fixative to sample?

Re: Water-cress?

My gut reaction is a Cardamine sp. Given the small size, hairs and 4 apparent stamens, have you ruled out C. hirsuta?

Steatoda bipunctata?

I'm hoping there may be somebody who knows a bit about those eight-legged things out there. Is this Steatoda bipunctata? Seems to fit on abdominal patterning but I'm not really up on spiders.

Collected 29/I/2018, Ilkeston, VC57

Thanks in advance.

Re: Microfungus on Garden Pansy

Update

After staining in Congo Red, there appears to be 0 - 2 septa (2 being exceptional) in the spores therefore I think we can safely conclude Ramularia agrestis var. agrestis Many thanks once again.

Re: Microfungus on Garden Pansy

Many thanks Chris for such a swift, informative and comprehensive reply. Ellis and Ellis describe R. agrestis as amphigenous and that was where I had ruled it out so yes, something stupid. Next time I shall use that to inform but not eliminate my selection. I wholeheartedly agree with your sentiment...

Microfungus on Garden Pansy

Can anybody enlighten me on what is causing the spotting on my Garden Pansy, Viola X wittrockiana leaves. I am assuming it is a hyphomycete. Apologies if this should have gone in the plant diseases forum, not quite sure what the protocol is with these. Location: Ilkeston,VC57 Date: 21/xi/2017 Pale b...
