Tales of the unexpected: angiocarpous representatives of the Russulaceae in tropical South East Asia.

Bottom Line: The placement of the species within Lactarius and its subgenera is confirmed by a molecular phylogeny based on ITS, LSU and rpb2 markers.The diversity of angiocarpous fungi in tropical areas is considered underestimated and driving evolutionary forces towards gasteromycetization are probably more diverse than generally assumed.The discovery of a large diversity of angiocarpous milkcaps on a rather local tropical scale was unexpected, and especially the fact that in Sri Lanka more angiocarpous than agaricoid Lactarius species are known now.

ABSTRACT
Six new sequestrate Lactarius species are described from tropical forests in South East Asia. Extensive macro- and microscopical descriptions and illustrations of the main anatomical features are provided. Similarities with other sequestrate Russulales and their phylogenetic relationships are discussed. The placement of the species within Lactarius and its subgenera is confirmed by a molecular phylogeny based on ITS, LSU and rpb2 markers. A species key of the new taxa, including five other known angiocarpous species from South East Asia reported to exude milk, is given. The diversity of angiocarpous fungi in tropical areas is considered underestimated and driving evolutionary forces towards gasteromycetization are probably more diverse than generally assumed. The discovery of a large diversity of angiocarpous milkcaps on a rather local tropical scale was unexpected, and especially the fact that in Sri Lanka more angiocarpous than agaricoid Lactarius species are known now.

ML tree (RAxML) based on ITS sequences. Bootstrap values are indicated if they exceed 50 %. Names in orange are the new angiocarpous species described in this paper, names in green are angiocarpous Lactarius species for which ITS sequences are available on GenBank. Arcangeliella sp. FJ454900 was obtained by sequencing plant roots; the fruiting body was not observed, and thus it is unclear whether this sequence is actually from an angiocarpous species. The scale bar represents the number of nucleotide changes per site.

The scale bar represents the number of nucleotide changes per site.

Mentions: Fig. 1 shows the obtained ML topology based on the alignment including only ITS sequences; bootstrap (BS) values are indicated on the branches. The six new sequestrate Lactarius species from South East Asia are indicated in orange and are clearly distinct from the previously known and sequenced sequestrate milk cap species (indicated in green).
