• Host suggests Sawadaea bicornis or Phyllactinia marissalii.
• Sawadaea bicornis suggested by macro: Epiphyllous, many chasmothecial appendages, projecting all over, uninflated bases, convoluted apices.
• Confirmed by appendages in micro.

Habitat: On some leaves of Acer campestre, in a small grove of mature trees, with Quercus robur and Crataegus cf. monogyna, around a hedge between a field and road, part of a large area of agricultural land being 'rewilded' (Knepp Estate), Low Weald, southern England, early November.

Chasmothecia: Black and yellowish specks seen on most downy patches, gregarious, only seen on the top sides of the leaves.

Low magnification (20-40x): Patches formed of +/- sparse mycelium on the surface of the leaf, chasmothecia with more or less anchoring hyphae (detaching with age?), sub-globose to globose, initially yellowish, then blackish, when mature with many hyphae-like appendages protruding all over or from the top, bases uninflated, apices of appendages noticeably convoluted (branching), short conidiophores, hyaline, conidia appear to be growing in chains at the apices, but greater magnification required.
