Lepiota rubella Bres., an unusual tropical American agaric from Turkey

Abstract

Mycologists have presented some new records of macrofungi in recent years from Turkey (Solak et al., 2009; Baş Sermenli & Işıloğlu, 2009). In 2004 an exceedingly small, reddish brown lepiotaceous agaric was found with whitish cream-coloured appendiculate, floccose marginal cortina on the pileus, tomentose-lanose stipe below a poorly developed ring-zone; it was found growing in association with Codiaeum (Euphorbiaceae) in a plant-pot. Microscopically the fungus appeared quite unique in its combination of small size of the basidiome, relatively small, elongate-ellipsoid basidiospores with no or at most vague dextrinoid reaction, and small projections on the hyphae of the suprapellis with the end cells clavate. This new record of interesting macrofungi was described as Lepiota rubella Bres
