The taxonomy and phylogeny of Hydropus subalpinus and Leucoinocybe lenta were investigated on the basis of morphological features and multi-gene molecular analysis (nrITS, nrLSU, tef-1α data sets) in order to elucidate the taxonomic status of these two rare species, and delineate a natural classification within the family Porotheleaceae. The results reinforced the con-clusion that Hydropus and Leucoinocybe represent independent genera separate from Clitocybula, Gerronema, Lignomphalia, Megacollybia, Porotheleum and Trogia. The genus Leucoinocybe in the analysis proves to be a monophyletic group, while the genus Hydropus is polyphyletic. In addition, this is the first report of Leucoinocybe lenta growing in forests of the relict endemic Liquidambar orientalis and Fagus orientalis is recorded as a new host for Hydropus subalpinus. The study de-scribes Hydropus subalpinus and Leucoinocybe lenta as new records and Hydropus and Leucoino-cybe as new genera records for Turkish mycobiota. Detailed description of the morphological char-acters, line drawings of salient micromorphological features and color photographs of these species are provided, and comparisons with phenetically similar and phylogenetically related species are presented. This survey provides hopefully useful information for future studies on the phylogeny and diversity of Hydropus and Leucoinocybe, and reveals the need for more molecular studies on collections of the Hydropoid clade.
