This issue of Mycological Research News features: In this issue; A new fungus genus associated with elk-urine impregnated litter; and Low cyanobiont selectivity in Antarctic lichens.

The part includes nine original papers. Tuberculina mycoparasites of rusts are shown to be part of the life-cycle of plant pathogenic Helicobasidium species. The chemistry of some smaller genera of Xylariaceae is documented, new cryptic species are reported in Daldinia, and the preservation of Rosellinia isolates compared. A revision of generic concepts in Coniella and Pilidiella is presented based on molecular phylogenetic approaches, and populations of Tuber aestivum, Letharia vulpina s. lat., and Phytophthora cactorum are compared. Finally, a major study of microfungi on fallen leaves in the tropics provides new insights on the characters of ubiquitous vs more specific fungi.

The following new scientific names are introduced in this part: Daldinia macaronesica, D. martinii, D. palmensis, D. raimundi, D. vanderguchtiae, Pilidiella destruens, P. diplodiopsis, and P. eucalyptorum spp. nov.; and P. diplodiella (syn. Phoma diplodiella), and P. petrakioidea (syn. Coniella petrakioidea) combs. nov.
