Macrofungi from Abies cephalonica forests and other intermixed tree species (Oxya Mt., central Greece) 1 2 1 D.M. DIMOU *, G.I. ZERVAKIS & E. POLEMIS * [email protected] 1Agricultural University of Athens, Lab. of General & Agricultural Microbiology, Iera Odos 75, GR-11855 Athens, Greece 2 [email protected] National Agricultural Research Foundation, Institute of Environmental Biotechnology, Lakonikis 87, GR-24100 Kalamata, Greece Abstract — In the course of a nine-year inventory in Mt. Oxya (central Greece) fir forests, a total of 358 taxa of macromycetes, belonging in 149 genera, have been recorded. Ninety eight taxa constitute new records, and five of them are first reports for the respective genera (Athelopsis, Crustoderma, Lentaria, Protodontia, Urnula). One hundred and one records for habitat/host/substrate are new for Greece, while some of these associations are reported for the first time in literature. Key words — biodiversity, macromycetes, fir, Mediterranean region, mushrooms Introduction The mycobiota of Greece was until recently poorly investigated since very few mycologists were active in the fields of fungal biodiversity, taxonomy and systematic. Until the end of ’90s, less than 1.000 species of macromycetes occurring in Greece had been reported by Greek and foreign researchers. Practically no collaboration existed between the scientific community and the rather few amateurs, who were active in this domain, and thus useful information that could be accumulated remained unexploited. Until then, published data were fragmentary in spatial, temporal and ecological terms. The authors introduced a different concept in their methodology, which was based on a long-term investigation of selected ecosystems and monitoring-inventorying of macrofungi throughout the year and for a period of usually 5-8 years.

Tenellula sect. Rhodellinae) from the Changbai Mountains, northeast China, is described as a new species. It is characterized by the red tinged pileus, slightly yellowing context, small basidia, short pleurocystidia, septate dermatocystidia with crystal contents, and a coniferous habitat. The phylogenetic trees based on ITS1-5.8S- ITS2 rDNA sequences fully support the establishment of the new species. Key words —Russulales, Russulaceae, taxonomy, morphology, Basidiomycota Introduction The worldwide genus ofRussula Pers. (Russulaceae, Russulales) is characterized by colorful fragile pileus, amyloid warty spores, abundant sphaerocysts in a heteromerous trama, and absence of latex (Romagnesi 1967, 1985; Singer 1986; Sarnari 1998, 2005). As a group of ectomycorrhizal fungi, it includes a large number of edible and medicinal species (Li et al. 2010). The genus has been extensively investigated with a long, rich and intensive taxonomic history in Europe (Miller & Buyck 2002). Although Russula species have been consumed in China as edible and medicinal use for a long time, their taxonomy has been overlooked (Li & Wen 2009, Li 2013).

  • A Taxonomic Investigation of Mycena in California
    A TAXONOMIC INVESTIGATION OF MYCENA IN CALIFORNIA A thesis submitted to the faculty of San Francisco State University In partial fulfillment of The requirements For the degree Master of Arts In Biology: Ecology and Systematic Biology by Brian Andrew Perry San Francisco, California November, 2002 Copyright by Brian Andrew Perry 2002 A Taxonomic Investigation of Mycena in California Mycena is a very large, cosmopolitan genus with members described from temperate and tropical regions of both the Northern and Southern Hemispheres. Although several monographic treatments of the genus have been published over the past 100 years, the genus remains largely undocumented for many regions worldwide. This study represents the first comprehensive taxonomic investigation of Mycena species found within California. The goal of the present research is to provide a resource for the identification of Mycena species within the state, and thereby serve as a basis for further investigation of taxonomic, evolutionary, and ecological relationships within the genus. Complete macro- and microscopic descriptions of the species occurring in California have been compiled based upon examination of fresh material and preserved herbarium collections. The present work recognizes a total of 61 Mycena species occurring within California, sixteen of which are new reports, and 3 of which represent previously undescribed taxa. I certify that this abstract is a correct representation of the content of this thesis. Dr. Dennis E. Desjardin (Chair, Thesis Committee) Date ACKNOWLEDGEMENTS I am deeply indebted to Dr. Dennis E. Desjardin for the role he has played as a teacher, mentor, advisor, and friend during my time at SFSU and beyond.

  • Mushrooming Be Advised That This Is a Pastime Where Impatience Is Not Your Friend
    by Michael Hopping IMPATIENCE IS INHERENT TO THE HUMAN CONDITION. Who doesn’t want to skip over the blah, blah, blah and get on with things? Okay, let’s do that. If you’re new to mushrooming be advised that this is a pastime where impatience is not your friend. And now, back to our regular programming. Imagine a nature scene. Is it dominated by plants and animals? Ordinarily, they are the most obvious creatures around. The fungi that also surround us tend to be invisible. Exceptions include the reproductive acts we call mushrooms. Those are staged by thready fungal networks, mycelia, living underground, in wood or on decaying matter. The “roots” sometimes seen at the base of mushrooms are links between the fruiting body and parent mycelium. Think of mushrooms as apples and the attached threads as multiple stems. Mushrooms can be picked, if done responsibly, without endangering the creatures that produce them. But fungi aren’t plants. A mycelium, like an animal, must obtain the sugar needed to power its cellular engines from outside sources. Some species partner with plants—the payoff for the plant being water and minerals courtesy of fungal extensions on its root system. Others fungi are parasites. Still others recycle dead material. The largest single organism on Earth may be a mycelium of Armillaria solidipes, a parasitic type of honey mushroom. This wispy monster occupies 3.4 square miles in the Blue Mountains of Oregon; its age is estimated at 2400 years. Mushroom cultivators are attuned to the health and behavior of the mycelia they farm.
