In the book Fungal Pathogenicity and the Plant's Response, proceedings of a symposium held at Long Ashton research Station, is a discussion between Professor Stahmann and Dr. Beyersbergen of a fungus-plant patholgical system where both produce ethylene. The ethylene results in greater resistance of the plant to new infections, but the established pathogen seems to keep ahead of the plant and is not harmed. (oops, c. date of above book is 1973, symposium 1971) This looks to me as if it might be an interesting means for the fungus to get ahead in competition, reducing the chance that another pathogen might also attack the plant. Does anyone have any information or opinions in this area? -- ***Doing strange things in the name of art AND science... Eric B.

I have included in this note a list of changes currently under consideration, and the complete list of names used for the species identified at the last fair. We are actively seeking advice on the appropriateness of the proposed changes as well as any other changes that we should consider. Personal opinions or preferences are welcome, though we would appreciate any references you can provide. We would also like to start using author citations with our species names. Our principal reference is Arora's "Mushrooms Demystified" which is sadly lacking in this information making this transition difficult. The current plan is to consult other reference books that include this information and if the descriptions appear match those in Arora, to adopt the author citation used. I would also find a detailed description of the meaning of such citations helpful. For example, from Miller's "Mushrooms of North America" what does '(Pers. ex Fr.) Kummer' mean versus say 'Vitt. ex Fr.' or '(Fr.) Karst'? I understand that Fr. = Fries, Pers. = Persoon, and Vitt. = Vittadini, but what are the parentheses and 'ex' (presumably latin for 'from') all about? Any advice on how to go about correctly using or finding this information would be of help.

How can I eliminate microsporidia in my virus solution? I need an answer to this question by Wednesday morning (24 November 1993) in order to save the following experiment. Experiment: Viability of Nuclear Polyhedrosis Virus excreted by two reptiles and an amphibian. Objectives: 1) Determine the viability of excreted Nuclear Polyhedrosis Virus 2) Estimate the quantity of virus ingested and excreted by the reptiles and amphibian. I fed caterpillars (Spodoptera. exigua) infected with NPV to a skink and a lizard and a toad. However, I did not know that the caterpillars were also infected with a nasty microsporidian. The feces from all three animals were collected and centrifuged to produce three 1 ml solutions of NPV (one solution from each animal). I want to bio-assay these three solutions to test the viability of the PV in them. However, all threey solutions are contaminated with microsporidia (a protozoan). (This is an interesting finding in itself, it implies that both NPV and microsporidia can withstand the vagaries of a trip through the vertebrate digestive system.) Nevertheless, I need to selectively get rid of the microsporidia in order test the viability of NPV with a bio-assay. If I can separate NPV and microsporidia without damaging either then I can separately test the viability of each. Possible solutions? 1) use a selective anti-biotic against the microsporidia 2) pasteurize the solution and hope that one will be destroyed and the other won't 3) use some form of a gradient a) centrifuge? b) sucrose gradient? c) other? Thanks in advance. BTW, please post answers directly to my e-mail address below as I have no direct access to this group. Daniel Guyot 35/1-2 Soi Aladin Phahonyothin Rd.
