  author={Jonathan L. Frank and Robert A Coffan and Darlene Southworth},
  pages={107 - 93}
A species of Psathyrella (Basidiomycota) with true gills has been observed fruiting underwater in the clear, cold, flowing waters of the upper Rogue River in Oregon. Fruiting bodies develop and mature in the main channel, where they are constantly submerged, and were observed fruiting over 11 wk. These mushrooms develop underwater, not on wood recently washed into the river. Substrates include water-logged wood, gravel and the silty riverbed. DNA sequences of the ITS region and a portion of the… 
Psathyrella aquatica Fruiting in vitro
In vitro fruiting under predominantly terrestrial conditions supports the hypothesis that P. aquatica may form terrestrial sporocarps, and terrestrial search parameters for this rare mushroom can now include cultural characters of the mycelium and morphological characters of sporOCarps observed in vitro.
Taxonomy and ecology of Physisporinus forming synnema-like structures in freshwater environments
SS and acanthophysis formation in wet habitats in streams and in culture could be recognized as new taxonomic and ecological characters of Physisporinus.
A new species of Psathyrella (Psathyrellaceae, Agaricales) from Italy
The fungus was initially identified as P.thujina (= P.almerensis) by means of both ecology and macro- and microscopic characteristics of the basidiomes, then referred to P.cladii-marisci sp.
Age-dependent mycorrhizal specificity in an invasive orchid, Oeceoclades maculata.
Oeceoclades maculata appears to be highly specific for fungi during seed germination, but unusually promiscuous as adult plants, which is surprising in two respects.
Linking mycorrhizas to sporocarps: a new species, Geopora cercocarpi, on Cercocarpus ledifolius (Rosaceae)
Morphological characters of a white hymenium, inrolled entire margin and large spores, along with a hypogeous habit and a mycorrhizal host of C. ledifolius, distinguished these specimens from previously described species as a new species, Geopora cercocarpi.
Balsamia (Sequestrate Helvellaceae, Ascomycota) in western North America
This work sequenced DNA from recent western North American Balsamia collections, assessed relationships by sequence similarity, and identified molecular taxonomic units, finding no clear evidence for separation of Balamia into multiple genera.


The mushroom family Psathyrellaceae: evidence for large-scale polyphyly of the genus Psathyrella.
Aquatic fungi from peat swamp palms: Phruensis brunneispora gen. et sp. nov. and its hyphomycete anamorph
Both morphological and molecular evidence supports erecting a new genus to accommodate Phruensis brunneispora, a new species occurring on decaying trunks of the palm Licuala longecalycata in Sirindhorn Peat Swamp Forest, Thailand.
Lucidascocarpa pulchella, a new ascomycete genus and species from freshwater habitats in the American tropics
A new fungus collected from submerged wood in Costa Rica and Ecuador has ascostromatic ascomata with fissitunicate asci and lacks pseudoparaphyses, characters that place it in the Dothideaceae
Evolution of Marine Mushrooms
The relationships among terrestrial and aquatic homobasidiomycetes are resolved using a data set of ribosomal DNA (rDNA) sequences that includes 5 aquatic species and 40 terrestrial species.
In vitro measurements of the competitive interactions between two saprobic basidiomycetes on Typha latifolia
Competition was asymmetric, with P. typhae the stronger competitor at both temperatures, and uninhibited by the presence of S. hydrophilum, demonstrating that competition in nature might be asymmetric.
The Dutch, French and British species of Psathyrella
The sole object of the present work is to furnish a monograph dealing exclusively with the species of the genus Psathyrella reported from the Netherlands, France and the British Isles.
Ultrastructure and evolution of ballistosporic basidiospores
The hilar appendix of Auricularia fuscosuccinea was simple compared with those of the Homobasidiomycetes, and basidiospores oiCoprinus cinereus was examined before and during spore discharge using light microscopy, and SEM of frozen-hydrated and other preparations.
Fungal biodiversity in aquatic habitats
It is predicted that many species remain to be discovered in aquatic habitats given the few taxonomic specialists studying these fungi, the few substrate types studied intensively, and the vast geographical area not yet sampled.
