Helsinki. ISSN 0453-3402. The new form genus Alciphila Harmaja (Hyphomycetes) is described. It is character­ ized by (i) a superficial mycelium composed of voluminous hyaline hyphae, (ii) conid­ ium development terminally in unspecialized hypha! ends, and (iii) large elongated brown aleurioconidia which possess a thick, complex wall with longitudinal ridges and a hyaline perisporium. The type and only species of the new genus is Alciphila vul­ garis Harmaja which is described as a new species at the same time. Judged from qualitative studies in the field and the herbarium, A. vulgaris occurs in a special ecolog­ ical niche: on forest litter and mosses which have been impregnated by the urine of European elk (Alces alces L.), accompanied by some species of the Pezizales (Asco­ mycetes). The species is reported from several localities in Finland and one in Norway. The interesting ecological niche concerned, a spot which has received elk urine, is discussed briefly.

The dataset includes 93 unique species from 40 genera of Pyronemataceae, and 34 species from 25 Ectomycorrhizae genera representing an additional 12 families of the class.

  • <I>Phymatotrichopsis Omnivora</I>
    Persoonia 22, 2009: 63 –74 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158509X430930 Molecular systematics of the cotton root rot pathogen, Phymatotrichopsis omnivora S.M. Marek1, K. Hansen2, M. Romanish3, 4, R.G. Thorn3 Key words Abstract Cotton root rot is an important soilborne disease of cotton and numerous dicot plants in the south-western United States and Mexico. The causal organism, Phymatotrichopsis omnivora (= Phymatotrichum omnivorum), is Ozonium known only as an asexual, holoanamorphic (mitosporic) fungus, and produces conidia resembling those of Botrytis. Pezizales Although the corticoid basidiomycetes Phanerochaete omnivora (Polyporales) and Sistotrema brinkmannii (Cantharel­ Phylogeny lales; both Agaricomycetes) have been suggested as teleomorphs of Phymatotrichopsis omnivora, phylogenetic Phymatotrichum root rot analyses of nuclear small- and large-subunit ribosomal DNA and subunit 2 of RNA polymerase II from multiple Pulchromyces fimicola isolates indicate that it is neither a basidiomycete nor closely related to other species of Botrytis (Sclerotiniaceae, rDNA Leotiomycetes). Phymatotrichopsis omnivora is a member of the family Rhizinaceae, Pezizales (Ascomycota: RPB2 Pezizomycetes) allied to Psilopezia and Rhizina.

INTRODUCTION Taxonomy The confused taxonomic history of the cotton root rot fungus A devastating disease of cotton in Texas, which caused large goes back more than a century. The causal agent was first numbers of plants in affected areas to suddenly wilt and die, identified by W.G. Farlow as Ozonium auricomum Link, based was first reported in the 1880s (Pammel 1888, 1889). The on nonsporulating mycelium associated with diseased roots disease has been variably called cotton root rot (after the (Pammel 1888).
