Hapalopilus percoctus Miettinen sp. nov. Figure 6

Holotype.

Botswana. Gaborone, Golf course, -24.652°: 25.936°, strip of natural bush, felled log or tree stump (40 cm in diameter), 28 May 2008, Reijo Miettinen (H 7008581).

Etymology.

Percoctus , parched, scorched; refers to the sun-exposed habitat of the species.

Remarks.

Similar to Hapalopilus rutilans with pileate basidiocarps. Microscopically otherwise identical, but Hapalopilus percoctus has clearly wider spores and tramal hyphae (Table 3). The spore dimensions come close to Hapalopilus eupatorii , which has larger pores, effused basidiocarps and grows usually on woody herbs. Its tramal hyphae are also narrower. Hapalopilus percoctus is the only species in the genus known to us from the Southern Hemisphere.
