R. alexandri R. aulacomniophila R. demissella R. fibula R. mellea R. minuta R. piquiniana R. straminea R. swartzii Rickenella is a genus of brightly colored bryophilous (moss inhabiting) agarics in the Hymenochaetales that have an omphalinoid morphology.

[1][2][3][4] They inhabit patches of moss that grow on soil, tree trunks and logs in temperate regions of the planet.

[6] Rickenella is most similar to Contumyces and Blasiphalia, from the former differing by having its cystidia on the cap, stipe, and hymenium solitary and scattered.

The hair-like cystidia on the cap and stipe give the small mushrooms a fuzzy appearance when viewed through a magnifying glass or hand lens.

Instead, Rickenella produces a small appressorium or no appressoria and penetrates the rhizoids of its moss hosts, growing within the cells.
