Leucocoprinus birnbaumii (Agaricales: Basidiomycota), attractive yellow houseplant mushroom, revisited after 100 years

Abstract

Sulphur yellow color fruiting bodies of a mushroom at several stages of development were found growing indoors, on decaying mosses (peat) inside a glass box in the University premises at Peradeniya in November 2018. The fungus was examined and identified by its morphological features, described previously, as Leucocoprinus birnbaumii. The present paper reports L. birnbaumii 110 years after its first record in Ceylon and describes its morphology using growth stages and color images.
