03F9F5524446FFCCFF4EFD62D46F31D0.taxon	description	Description: — Sporophores crowded, formed by several small sporocarps, sessile, marked with ridges that give it a polygonal appearance, up to 0.4 mm high, 0.3 – 0.5 × 0.4 – 0.52 mm diam. Hypothallus white (1 BA), well-developed, persistent, usually covered with lime incrustation. Peridium double, with scattered deposits of lime granules, outer layer greyish white (1 BA), with prominent, robust transverse and longitudinal ridges that give it a rough appearance, reticular dehiscence caused by the rupture of ridges. Columella greyish yellow (3 C 3), globose, calcareous. Capillitial smooth to wrinkled, brown, without calcareous intercalations, simple to branched with free ends. Spore-mass yellowish brown (5 F 8). Spores (8.3 –) 9.3 – 11 (– 12.7) × (10.2 –) 11.2 – 13.3 (– 13.8) µm [Q = (1) 1.1 – 1.3 (– 1.4); Qm = 1.2; N = 30], globose to subglobose, violet-brown, with prominent, irregular lines that sometimes confer an angular shape, strongly warty; in SEM the warts can be described as rounded to lanceolate, occasionally bifurcated and arranged irregularly. Habitat: — Sporophores growing on decaying wood and on insect remains (coleoptera) in the mesophilic forest. Known distribution: — Known only in Brazil Central, in the state of Goiás, in a Cerrado ecosystem.	en	Moreira, Izabel Cristina, Leonardo-Silva, Lucas, Xavier-Santos, Solange (2025): Diderma laiseae (Didymiaceae, Physarales), a new species of Myxomycetes from Brazil.
