Astrothelium marcidum

Ciri dan struktur

The thallus (the lichen body) is (bearing a ) olive-brown, and smooth to uneven. The spore-producing structures (ascomata) are astrothelioid: several chambers are joined together and share fused, slightly off-center pores (ostioles). These joined ascomata form small (a compact tissue mass that houses the chambers) that are about 0.7–1.0 mm across, immersed in the thallus and becoming (breaking through the surface). They are covered either by the surrounding thallus or by a thin yellowish-white layer. The internal hyphal matrix () is clear. Each ascus contains eight colorless (hyaline), 3-septate, to ellipsoid ascospores measuring roughly 35–45 × 14–16 μm; the spores do not stain with iodine (IKI−). Standard spot tests are negative on both thallus and ascomata (UV−, K−), and thin-layer chromatography detects no lichen products.
