Xylodon pumilius (Gresl. & Rajchenb.) K.H. Larss. comb. nov.

Basionym.

Hyphodontia pumilia Gresl. & Rajchenb., Mycologia 92: 1162. 2000.

Type.

Argentina. Chubut. Dpto Languiñeo, Lago Engaño, on Nothofagus pumilio , 19 Apr 1996, A.Greslebin 650 (holotype BAFC [50031], by original designation).

For a detailed description and illustration, see Greslebin and Rajchenberg (2000). The presence of both hymenial, capitate cystidia and enclosed, tubular to moniliform cystidia with homogenous contents strongly stained by cotton blue, make this species morphologically reminiscent of Xylodon brevisetus and X. tuberculatus . X. pumilius differs from both by a smooth hymenium and thick-walled basidiospores.
