@bitheolaidhe.bsky.socialGoing back through these rust specimens I'm reminded of many happy summer days spent in the field :D

@bitheolaidhe.bsky.socialAn unexpectedly large component of my research involves cutting out tiny bits of leaves and putting them in tubes
@bitheolaidhe.bsky.socialI'll defer to @ruhrpottpilze.bsky.social , this is a tricky group!
@bitheolaidhe.bsky.socialErysiphe trifoliorum is blessedly unproblematic though 😁
@bitheolaidhe.bsky.socialIt can be quite good, though it will also ID fungi that aren't actually there for example if you give a photo of a leaf taken with an angle that matches the photos with the fungus. It can often be overconfident (an issue with the training data) e.g. IDing Ramularia rubella for any leaf spot on Rumex
@bitheolaidhe.bsky.socialI was just thinking that, George Monbiot has been commenting on the state of british tuna recently, which only reappeared in any numbers in the last 5 years or so and are already (!) being commercially fished

@lizzie-harper.bsky.socialReposted by @bitheolaidhe.bsky.socialVery very excited to say that the books I've been working on are ready to pre-order!
The second is "Art in the Field:Fungi" & covers drawing techniques & exercises, pencil skills, watercolour tips, & step by step projects for all levels...

@johnwalterswildife.bsky.socialReposted by @bitheolaidhe.bsky.socialGood to chat with Martin Cade watch Red-backed Shrike & a 2 mm long extremophile beetle Octhebius lejolisii, somehow it survives in splash zone pools with extremes of heat and dessication, true survivors that will probably still be going strong when we are all gone! @portlandbirdobs.bsky.social
@bitheolaidhe.bsky.socialPodosphaera thalictri (distinguishable microscopically) is also known from this host genus, though no records from B&I yet. Erysiphe on Thalictrum hasn't been sequenced yet afaik so we can only call it Erysiphe aquilegiae sensu lato, see incomplete discussion here www.inaturalist.org/observations...
@norwichbirder.bsky.socialReposted by @bitheolaidhe.bsky.socialI assume this species is fairly common but overlooked - Pale Hogweed Aphid, Paramyzus heraclei (influentialpoints.com/Gallery/Para...) at Whitlingham C.P. today. It feeds on the underside of Hogweed leaves, but handily creates this yellow mottling on the upperside. New for my #NorwichAphids list.
@bitheolaidhe.bsky.socialNew to me and to Wales today was Peronospora campestris on Arenaria serpyllifolia, found with Peter Jackson at Morfa Dyffryn in Gwynedd

@bitheolaidhe.bsky.socialI have no idea sorry 😆 I'm not actually very experienced with pathogens of trees, I mostly do herbaceous hosts
@bitheolaidhe.bsky.socialHmm I would look at a cross section under a compound microscope, there are endless anonymous ascomycetes that look a bit like this
@georgemonbiot.bsky.socialReposted by @bitheolaidhe.bsky.socialThis is how we should see these magnificant animals, not hauled up on a boat or in fillets on a slab. We should no more catch or kill this rare and stunning megafauna than we should trap or kill tigers or whales. Here are some more of Rupert’s photos from yesterday, with his kind permission.
@science.orgReposted by @bitheolaidhe.bsky.socialFollowing backlash from scientists, CRANE says it has suspended all grant decisions for this funding call and committed to sending rejected proposals for human review. https://scim.ag/46Qiqv3
@bitheolaidhe.bsky.socialYes it's what I see them on most often (possibly just because it's so common)
@bitheolaidhe.bsky.social22-spot is feeding on Erysiphe heraclei :)

@bitheolaidhe.bsky.socialYeah the measuring line in imagej isn't determined by the resolution of the image, I think it's stored as a vector. It's much faster and easier than counting pixels too!
