0.5-2.5(3.5) cm, starts flat with incurved margin, depressed or funnel-shaped when old, margin often wavy; “dull cinnamon to brownish, fading to yellowish or straw color or paler as it ages”; smooth, not viscid, margin striate

we should change this name to Omphalina ericetorun?
Index Fungorum prefers Omphalina ericetorum instead of Lichenomphalia umbellifera (Esslinger’s preferred name). As this is a mushroom site(you mean Fungorum, right???), not a lichen site, it seems to make more sense to side with Index Fungorum where there is debate.
