Choke

Choke (Epichloe typhina) is an endophytic and pathogenic fungus in the family Clavicipitaceae, phylum Ascomycota, that colonises the tissues of various cool-season grasses (Poaceae) across Europe and North America. The name refers to the disease it causes — infected grass tillers are typically 'choked' (prevented from flowering) when the fungus produces a dense, white to cream-coloured, stromata (a compact fungal structure) that surrounds the flowering stem before it can emerge, suppressing seed production. Epichloe species exist along a mutualism-parasitism continuum; some strains are biotrophic endophytes living almost entirely within grass tissues without obvious symptoms and conferring benefits to the host such as increased drought resistance and deterrence of herbivores through alkaloid production, while others — including E. typhina — are more parasitic in nature, sterilising infected host tillers. The fungus spreads via airborne ascospores produced on its stroma that infect new host plants. Related Epichloe/Neotyphodium endophytes are of great practical importance to agriculture as they produce ergot alkaloids and other compounds that can cause toxicosis in livestock grazing infected pasture grasses. As a fungal pathogen/endophyte rather than a wildlife species, it is Not Evaluated by the IUCN.

clouded brindle

The clouded brindle (Apamea epomidion) is a noctuid moth in the family Noctuidae found across temperate Europe and extending into western Asia. The adult wingspan measures approximately 35–45 mm with typical brindle-patterned forewings in grey-brown and buff tones with subtle cross-lines and stigmata characteristic of the Apamea genus. The term 'clouded' refers to diffuse cloud-like darker shading areas across the forewing surface. Adults fly in one generation from June to August, attracted to light and flowers at night. The larvae are internal feeders within grass stems and roots, feeding on coarse grass species such as Brachypodium sylvaticum and Deschampsia in woodland rides, scrub margins, and rough grassland habitats. The pupal stage overwinters in soil or within plant debris. The clouded brindle inhabits structurally diverse woodland edge habitats with a mixture of tall grasses, scrub, and open canopy woodland rides that provide both larval foodplants and adult resting sites. Changes in woodland management, particularly reduction of coppicing and shading of woodland rides, may affect this and related grass-feeding brindle moth species.
