Abstract

Lycoperdon rupicola and L. subumbrinum are here described as new species. The former is a morphologically characteristic species forming small subglobose to pyriforme fruiting bodies with a prominent, protruding and stellately lobed stoma. In the phylogenetic analyses the six sequences of L. rupicola form a clade with 100% BS and 1.0 BPP, clustering with L. dermoxanthum. The proposed species grows among mosses on siliceous boulders and flat rocks as well as on open, sandy soil in temperate and hemiboreal regions. The records to date indicate its presence in Fennoscandia and Spain (Catalunya). L. subumbrinum morphologically resembles L. umbrinum but differs in having coarser ornamentation of its spores. In the phylogenetic analyses the five sequences of L. subumbrinum form a clade with 100% BS and 1.0 BPP, clustering with L. muscorum. The records to date, originating from southernmost Sweden and NW Slovakia, indicate that L. subumbrinum is a species of rich deciduous forests.

L. muscorum is recorded for the first time from the Iberian peninsula (Spain).
