Re: Arum maculatum: a full set

Thanks Chris for your opinion. I was lead to believe that the spotting (very common round here too) was different to the sunken depressions as the spotting tends not to be visible as greyish markings on the underside (this is how I initially screened the leaves). When I say gunk, they look reminisce...

Re: Arum maculatum: a full set

I shall try again. Unfortunately, I cannot get images of the smut spores. What looks like a very good spore through the eyepiece looks like a blob of gunk through the camera. I really need to improve my micrograph technique. I collected fresh material today from the same plants so if anybody would c...

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...
