Conservation Status: Not of concern
Arrhenia in the traditional sense includes small, thin, pliable-fleshed mushrooms that are spoon-, petal- or cup shaped, often lobed, and without a stipe or with a lateral one. The fertile surface is smooth, or bears anastomosing veins or blunt gills. They occur on soil or in association with mosses and often can hardly be seen among the mosses when dried. It is widely distributed and can be found in both urban and forested areas. A. lobata (Persoon: Fries) Redhead is a moss-associated species often found in fens, along streams, or in association with melting snow. Old faded specimens can be confused with Cyphellostereum laeve.
