Abstract: Five species of boletes, Chalciporus piperatus, Suillus brevipes, S. granulatus, S. salmonicolor, and Pulveroboletus xylophilus and three species of Amanita, A. marmorata subsp. myrtacearum, A. muscaria var. formosa, and A. manicata have been collected in the Hawaiian Islands. The boletes are associated with introduced pines and the Amanita are associated with introduced pines, Myrtaceae and Casuarina. Pulveroboletus xylophilus and Amanita manicata appear to be saprotrophic instead of mycorrhizal. Key Words: boletes, Amanita, Hawai’i 168 Hemmes and Desjardin.

(2005): Central European genera of the Boletaceae and Suillaceae, with notes on their anatomical characters. - Czech Mycol. 57: 1-50. A taxonomic survey of Central European genera of the families Boletaceae and Suillaceae with tubular hymenophores, including the lamellate Phylloporus, is presented. Questions concerning the delimitation of the bolete genera are discussed. Descriptions and keys to the families and genera are based predominantly on anatomical characters of the carpophores. Attention is also paid to peripheral layers of stipe tissue, whose anatomical structure has not been sufficiently studied. The study of these layers, above all of the caulohymenium and the lateral stipe stratum, can provide information important for a better understanding of relationships between taxonomic groups in these families. The presence (or absence) of the caulohymenium with spore-bearing caulobasidia on the stipe surface is here considered as a significant ge­ neric character of boletes. A new combination, Pseudoboletus astraeicola (Imazeki) Šutara, is proposed. Key words: Boletaceae, Suillaceae, generic taxonomy, anatomical characters. Šutara J.

  • Response of Ectomycorrhizal Fungal Fruiting to Nitrogen And
    RESPONSE OF ECTOMYCORRHIZAL FUNGAL FRUITING TO NITROGEN AND PHOSPHORUS ADDITIONS IN BARTLETT EXPERIMENTAL FOREST, NEW HAMPSHIRE By Claudia N. Victoroff A thesis submitted in partial fulfillment of the requirements for the Master of Science Degree State University of New York College of Environmental Science and Forestry Syracuse, New York Department of Environmental and Forest Biology Approved by: Thomas R. Horton, Major Professor Theodore Dibble, Examining Committee Chairperson Melissa Fierke, Department Chairperson S. Scott Shannon, Dean, the Graduate School Acknowledgments Throughout the course of my master’s I have benefitted from the support of my lab mates, friends, and loved ones. I owe so much to my mentor Dr. Tom Horton. Tom has helped me to grow into a scientist. I entered ESF the summer after finishing my undergraduate and Tom’s guidance has helped me to develop away from insecurity and (closer) to self-directedness. The lab culture that Tom inspires is a cooperative and productive work environment and I am so thankful that I was able to be a part of it. The ESF community is unique. The curious minds of the undergraduates have inspired me, and the expertise of the faculty has challenged and motivated me. I have been supported through teaching assistantships by Tom (EFB 320 General Ecology Laboratory) and by Dr. Stewart Diemont (EFB 120 Global Environments Lecture). Tom and Stew have been excellent role models for me to adapt my own teaching style from. I am thankful for my graduate committee. Together my committee has directed my research and each member has benefitted my academic career significantly.

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.

  • Bulk Isolation of Basidiospores from Wild Mushrooms by Electrostatic Attraction with Low Risk of Microbial Contaminations Kiran Lakkireddy1,2 and Ursula Kües1,2*
    Lakkireddy and Kües AMB Expr (2017) 7:28 DOI 10.1186/s13568-017-0326-0 ORIGINAL ARTICLE Open Access Bulk isolation of basidiospores from wild mushrooms by electrostatic attraction with low risk of microbial contaminations Kiran Lakkireddy1,2 and Ursula Kües1,2* Abstract The basidiospores of most Agaricomycetes are ballistospores. They are propelled off from their basidia at maturity when Buller’s drop develops at high humidity at the hilar spore appendix and fuses with a liquid film formed on the adaxial side of the spore. Spores are catapulted into the free air space between hymenia and fall then out of the mushroom’s cap by gravity. Here we show for 66 different species that ballistospores from mushrooms can be attracted against gravity to electrostatic charged plastic surfaces. Charges on basidiospores can influence this effect. We used this feature to selectively collect basidiospores in sterile plastic Petri-dish lids from mushrooms which were positioned upside-down onto wet paper tissues for spore release into the air. Bulks of 104 to >107 spores were obtained overnight in the plastic lids above the reversed fruiting bodies, between 104 and 106 spores already after 2–4 h incubation. In plating tests on agar medium, we rarely observed in the harvested spore solutions contamina- tions by other fungi (mostly none to up to in 10% of samples in different test series) and infrequently by bacteria (in between 0 and 22% of samples of test series) which could mostly be suppressed by bactericides. We thus show that it is possible to obtain clean basidiospore samples from wild mushrooms.

  • Xerocomus S. L. in the Light of the Present State of Knowledge
    CZECH MYCOL. 60(1): 29–62, 2008 Xerocomus s. l. in the light of the present state of knowledge JOSEF ŠUTARA Prosetická 239, 415 01 Teplice, Czech Republic [email protected] Šutara J. (2008): Xerocomus s. l. in the light of the present state of knowledge. – Czech Mycol. 60(1): 29–62. The definition of the generic limits of Xerocomus s. l. and particularly the delimitation of this genus from Boletus is very unclear and controversial. During his study of European species of the Boletaceae, the author has come to the conclusion that Xerocomus in a wide concept is a heterogeneous mixture of several groups of species. These groups are separated from each other by different anatomical and some other characters. Also recent molecular studies show that Xerocomus s. l. is not a monophyletic group. In agreement with these facts, the European species of Xerocomus s. l. whose anatomy was studied by the present author are here classified into the following, more distinctly delimited genera: Xerocomus s. str., Phylloporus, Xerocomellus gen. nov., Hemileccinum gen. nov. and Pseudoboletus. Boletus badius and Boletus moravicus, also often treated as species of Xerocomus, are retained for the present in the genus Boletus. The differences between Xerocomus s. str., Phylloporus, Xerocomellus, Hemileccinum, Pseudoboletus and Boletus (which is related to this group of genera) are discussed in detail. Two new genera, Xerocomellus and Hemileccinum, and necessary new combinations of species names are proposed.

Mycorrhizal Fungi of Aspen Forests: Natural Occurrence and Potential Applications Cathy L. Cripps1 Abstract—Native mycorrhizal fungi associated with aspen were surveyed on three soil types in the north-central Rocky Mountains. Selected isolates were tested for the ability to enhance aspen seedling growth in vitro. Over 50 species of ectomycorrhizal fungi occur with Populus tremuloides in this region, primarily basidiomycete fungi in the Agaricales. Almost one-third (30%) were ubiquitous with aspen and were found on all three soil types. Over one-third (37%) were restricted to the acidic, sandy soil of the smelter-impacted Butte-Anaconda area, revealing a subset of fungi that tolerate these conditions. Mycorrhizal fungi were screened for their ability to enhance aspen growth and establishment. Of nine selected isolates, all but one increased the biomass of aspen seedlings 2–4 times.
