Notes on Taxonomy: [Edit] Brief Description:

Discussion: Diagnostic features of Marasmius xestocephalus include: a greyish yellow to yellowish orange pileus with yellowish brown disc; subdistant (15-18), narrow, pale yellow lamellae; a pubescent to subvelutinous stipe; fusoid basidiospores with mean 12.5 × 3.7 μm; and apically forked caulocystidia. The Thai material is indistinguishable from the protologue (Singer, 1964) and redescription of M. xestocephalus by Pegler, (1977), and differs only slightly from the recent description provided by Antonín (2007) who reported broader basidiospores (4.5-5.5 μm diam.). Until further material of this species is collected, sequenced and compared with Thai specimens, we tentatively recognize our species as M. xestocephalus.
