Tubariomyces

Tubariomyces Esteve-Rav. & Matheny, in Alvarado et al., Mycologia 102(6): 1390 (2010)

Etymology. Due to its similarity in habit to genus Tubaria (W.G. Sm.) Gillet.

Basidiomata tubarioid, lamellate, non-sequestrate, pileus convex to plano-convex, velutinous, furfuraceous, tomentose to squamulose, cortina fugacious, context not reddening, cheilocystidia thin-walled, not crystalliferous, subcylindrical to subclavate, usually elongate, caulocystidia present, similar to cheilocystidia, basidia necropigmented, basidiospores smooth, pale yellow-brown to ochraceous in water and hyaline alkaline mounts, apiculus indistinct or small, pileipellis a trichodermium, clamp-connections present. Associated with Cistaceae. Holotype: Tubariomyces inexpectatus (M. Villarreal, Esteve-Rav., Heykoop & E. Horak) Esteve-Rav. & Matheny.

Index Fungorum number: IF518073

Type species: Tubariomyces inexpectatus (M. Villarreal, Esteve-Rav., Heykoop & E. Horak) Esteve-Rav. & Matheny, in Alvarado et al., Mycologia 102(6): 1393 (2010)

Notes: The decurrent lamellae (‘‘tubarioid habit’’) and presence of caulocystidia along the surface of the stipe make this genus morphologically distinct from other genera and major clades of Inocybaceae. The first impression reminded us of a small Tubaria species (especially T. inexpectatus), although both genera are micromorphologically different. Most species of the Mallocybe clade show adnate to emarginate lamellae, except for a few species, such as I. heimii Bon or I. agardhii (N. Lund) P.D.Orton, which sometimes exhibit subdecurrent lamellae. However, species of the Mallocybe clade are typically larger and lack the characteristic caulocystidia of Tubariomyces species.
