Haplohymenium triste (Ces.) Kindb.

SPECIMEN EXAMINED. — Madagascar. Toliara: Fort Dauphin (Tôlanaro) region; NE of city, in region called Mandena, beyond Botanical Garden and QIT camp, in forest remnants near coastal lake; 25 m; 24°57’S, 47°00’E; 31.X.1989; McPherson & Dumetz 14342A (MO[MO-3965910]!).

NOTES

This is another widespread taxon that in Africa has been reported from Réunion ( Müller 2002; Arts 2005) and doubtfully from Kenya ( O’Shea 2000). Recently, it has also been confirmed for South Africa ( Hedderson 2020). Its distribution includes temperate parts of the northern hemisphere and its morphology and separation from closely related taxa is well-treated by Watanabe (1972). Haplohymenium pseudotriste (Müll.Hal.) Broth. is similar and both species occur on Réunion (illustrated inArts 2005). However, after consulting examples of both species, the single Malagasy specimen seems best placed in H. triste , adding yet another new genus for Madagascar.
