Pilophoron conglomeratum F.Wilson, Victorian Naturalist 6: 68 (1889); republished in J. Linn. Soc., Bot. 28: 372 (1891). T: Black Spur, Vic., F.R.M.Wilson 70; holo: BM.
  Primary thallus emerald green, occasionally brownish or yellowish green, granular, forming a contiguous or rather dispersed, widespreading crust over a thin brown to black prothallus. Podetia to 25 mm tall, 1–4 mm wide, subterete, longitudinally striate and fissured, covered with green corticate granules or decorticate and pale to brownish in patches, mostly simple, becoming irregularly branched towards apices. Apothecia 1–5 mm wide, subglobose, becoming irregularly convoluted, pale reddish to dark brown, commonly forming cerebriform, conglomerate clusters to 5 (–10) mm wide. Ascospores usually 8–13 × 2.5–3.5 µm. Pycnidia mostly at apices of sterile pin-like podetia to c. 2 mm tall, dispersed, or crowded in sterile thalli, black-brown. CHEMISTRY: protolichesterinic and lichesterinic acid, ±atranorin. N.Z. populations contain caperatic acid (Galloway & James, op. cit. 568).
  Common and widespread in Tas. from sea level to alpine altitudes in cool temperate rainforest, on moist shaded tree trunks or rotting wood, usually over bryophytes. Uncommon in Vic., but sterile thalli possibly overlooked. Rare in Qld. Also in N.Z.
