Clitopaxillus

Clitopaxillus G. Moreno, Vizzini, Consiglio & P. Alvarado, in Alvarado et al., Fungal Diversity. 90:109-133 (2018)

Etymology: from Clitocybe and Paxillus, the genera where C. alexandri was previously classified.

Diagnosis: basidiomes large-sized, clitocyboid, fleshy, with convex to flattened brownish pileus lacking umbo, glabrous pileipellis, not hygrophanous. Lamellae deeply decurrent. Spores slightly amyloid, ovoid. Saprobic, on litter. Clamp connections present at least on hymenophoral hyphae and mycelium. Northern Hemisphere, Europe and North Africa.

Index Fungorum number: IF823303

Type species: Clitopaxillus alexandri (Gillet) G. Moreno, Vizzini, Consiglio & P. Alvarado, in Alvarado et al., Fungal Diversity. 90:109-133 (2018)

Notes: Species of Clitopaxillus were previously considered members of Clitocybe section Disciformes (Fr.) Quél., along with C. harperi (Singer 1986; Bon 1991). Another remarkable member of this section is C. nebularis, currently retained as the most suitable lectotype species of Clitocybe (for discussion see Redhead et al. 2002), which lacks a central umbo and loop-like clamp connections, and has cyanophilous, non-amyloid and rough spores, and which belongs phylogenetically to the Clitocybeae clade (Matheny et al. 2006).
