– Although critical for the functioning of ecosystems, fungi are poorly known in highlatitude regions. This paper summarizes the results of the first genetic diversity assessments of Russula and Lactarius, two of the most diverse and abundant fungal genera in Alaska. LSU rDNA sequences from both curated sporocarp collections and soil PCR clone libraries sampled in various types of boreal forest...

The Family Russulaceae comprises of some important agaricoid and gasteroid taxa of Agaricomycetes. Two genera, Lactarius and Russula are distinctive basidiomycetes that possesses heteromerous tissue composed of sphaerocyte cells and amyloid ornamentation on their basidiospores. Some of the important ectomycorrhizal, edible, poisonous and medicinal species have been rested in genera Lactarius an...

Two new highly oxidized humulane sesquiterpenes, mitissimols D (1) and E (2) were isolated from the fruiting bodies of Lactarius mitissimus. Their structures were elucidated using extensive spectroscopic techniques including 1D and 2D NMR spectra.

The present study describes antioxidant properties of six wild mushrooms (Boletus edulis Bull., Boletus regius Krombh., Leccinum pseudoscaber Kallenb., Boletus impolitus Fr., Lactarius volemus Fr., and Lactarius deliciosus (L.) Gray) collected in Serbia. The antioxidant properties were assessed through the evaluation of the reducing power and radical scavenging ability of the samples. The Bolet...

Ectomycorrhizal (ECM) fungal composition was examined in a Pinus tabulaeformis Carr. forest. A total of 28 root samples of P. tabulaeformis were collected in June and September. Thirty-five ECM morphotypes were identified according to ECM morphological characters, and 26 ECM fungi were identified based on the analyses of ITS-RFLP and ITS sequences. Tomentella, Sebacina, and Tuber were common ge...

Three new plant growth regulatory sesquiterpenoids were isolated from the Lactarius repraesentaneus fungus. Their structures were elucidated to be a protoilludene sesquiterpene, namely repraesentin A (1), and two related sesquiterpenes, namely repraesentins B (2) and C (3). Compounds 1-3 showed promotion activities toward the radicle elongation of lettuce seedlings by 136%, 118% and 184% at 67 ...
