Chlorophyllum sect. Parvispororum Z.W. Ge sect. nov.

Diagnosis.

Differs from other sections by the relatively smaller, porous basidiospores (less than 10 μm long) and a pileipellis composed of a palisade of hyphae with cylindrical terminal elements.

Type.

Chlorophyllum subrhacodes (Murrill) Vellinga, Mycotaxon 83: 416. 2002.

Lepiota subrhacodes Murrill, Lloydia 6: 223. 1943.

Description.

Basidiocarps small to medium-sized, agaricoid, covered with large squamules contrasting in colour with the background. Basidiospores relatively small (less than 10 μm long), with germ pore, forming a truncated apex. Cheilocystidia clavate to mucronate clavate. Pileipellis a palisade of hyphae with cylindrical terminal elements. Hyphae without clamp connections.

Discussion.

This section contains the species from south-eastern North America ( C. subrhacodes ) and east Asia ( C. neomastoideum ) displaying an America-Asia disjunct distribution.
