Felt galls produced by the mite Aceria pseudoplatani also appearing on new Sycamore leaves. Seen in Blaise Woods this afternoon. British Plant Galls #TwitterNatureCommunity

Little red galls of the mite Aceria cephalonea starting to appear on new Sycamore leaves in Blaise Woods this afternoon. British Plant Galls #TwitterNatureCommunity

A brief foray into Blaise Woods this afternoon. I came across this fly sat on the underside of a Wavy Bitter-cress leaf. It was actually quite dead, a victim of the pathogenic fungus Entomophthora muscae. Creepy! 😬 British Mycological Society #TwitterNatureCommunity

Found in the grounds of my workplace this evening, the powdery mildew Podosphaera clandestina var. clandestina on Hawthorn leaves. Always on the lookout for plant pathogens wherever I am! 😉British Mycological Society #TwitterNatureCommunity

I came across across a few examples of these distinctive, zoned brown leaf spots on Bramble (Rubus fruticosus agg.) whilst out and about today. I've not been able to pin down a potential plant pathogen (fungal?) yet. Any ideas folks? #TwitterNatureCommunity

An interesting fungal plant pathogen, also found on Wood Avens at Kingsweston Down. I think that it might be Sphaerulina gei (?) 🤔 British Mycological Society #TwitterNatureCommunity

A rather stunted Wood Avens (Geum urbanum) plant in Blaise Woods today, covered in galls produced by the mite Cecidophyes nudus. British Plant Galls #TwitterNatureCommunity

Another street find just outside someone's front garden today. The rust fungus Puccinia vincae looking even more pronounced on Variegated Greater Periwinkle (Vinca major variegata). British Mycological Society #TwitterNatureCommunity

Urban streets can be just as rewarding as 'wild' areas when hunting for plant pathogens. This unhappy-looking Cleavers plant has been affected by the powdery mildew Neoerysiphe galii. Found not far from home today. British Mycological Society #TwitterNatureCommunity

I spied some interesting looking yellow patches on the leaves of a Primrose plant in Leigh Woods today. Not the hoped-for Puccinia primulae but a nice find nonetheless - the fungal pathogen Ramularia interstitialis. British Mycological Society #TwitterNatureCommunity

Also by Clifton Suspension Bridge, leaf spots on Common Rock-rose (Helianthemum nummularium). Produced, I think, by Septoria chamaecysti. British Mycological Society #TwitterNatureCommunity

A hike over to Leigh Woods today, quite a few plant pathogens around so I was as happy as larry! First up, leaf spots produced by Ramularia valerianae var. centranthi on Red Valerian by Clifton Suspension Bridge. British Mycological Society #TwitterNatureCommunity

Whilst admiring the Green-winged Orchids at 'The Royals' I spotted a rust fungus on the leaves of Sweet Vernal-grass (Anthoxanthum odoratum). I think that it might be Puccinia brachypodii var. poae-nemoralis 🤔 ? British Mycological Society #TwitterNatureCommunity

In the unimproved grassland of 'The Royals' on the Blaise Castle Estate, Green-winged Orchids (Anacamptis moria) now starting to flower. BSBI: Botanical Society of Britain & Ireland #TwitterNatureCommunity
