Compte — Rendu des Activities de la Societe Mycologique de France Pendent L'annee 1970
15 G. E. MATHISON and J. O'SULLIVAN - "The dermatophytes - pathogenicity problems" Dr. Mathison discussed the general problems in the pathogenicity referring particularly to the relevance of keratinophilia and the possible role of proteolytic enzymes. Dr. O'Sullivan then introduced our studie.s on the proteolytic system of Microsporum canis which has been shown to be a three-component system. The system is inducible by proteins and repressible by amino acids in the medium. During the di auxi c lag between exhaustion of amino acids in the medium and after the introduction of protein, para-mural bodies appear between the plasmalemma and cell wall and at the hyphal tips. They are always present when protein is the sole source of nitrogen in the medium. Evlde ac e was presented that they are organelles whose Iunc tion is secretion. R. R. DAVIES - "Aerobiology in relation to allergy and mycoses" The prevalence of bronchial asthma and its production by fungal spores was briefly described. The relief of asthma in the Alps and a survey in which the spore content of the air at Davos was compared with that of London was reported. It was concluded that the relief of asthma in the Alps was due to remoteness from spore clouds produced by arable farming, and the climatological features of the valleys which effect low diurnal and high nocturnal spore concentrations. Evidencewas discussed which suggest that in Britain areas to the SouthEast of the Fosse Way present a worse environment for the person who suffers from allergic bronchial asthma, than do the heath and moorland areas to the North West. The effect of season on the prevalence of opportunist fungal infection in the immunosuppressed, and the animal lung as a sampler for airborne fungi was noted. The concensus of opinion among the participants was that this had been a very well worthwhile meeting and it undoubtedly highlighted the need for more work to be done in this no-man's land of mycology with strong animal connections. It was also plain that the workers who are tackling these intricate problems often with minimal resources deserve every encouragement and recognition. The President in closing the meeting expressed the cordial thanks of the BMS and our colleagues from the Society of Mycopathology to the local organisers especially our programme secretary, Dr. M. F. Madelin.
COMPTE - RENDU DES ACTIVITIES DE LA SOCIETE MYCOLOGIQUE DE FRANCE PENDENT L'ANNEE 1970 by H. Romagnesi In 1970 the S. M. Fr continued its activities in all fields. At the monthly meetings the nurne r cus papers given, of which many were published in the Quarterly Bulletin, gave rise to interesting discussions. In particular two colleagues told us of the appearance of Anthurus archeri in the north of the Paris Basin - a new extension of its area. M. Noel ARPIN who has produced a thesis on the carotenoid pigments of the Discomycetes gave an illustrated talk on May 4th showing the principal consequences of the analysis of different types of pigments on classification, particularly in Ru s sulas, Cortinariuses, Boleti, Ghante r e Ile s, C lavarias and Pezizas. This meeting created great interest.
16 At other meetings, especially that in ,January several keen photographers showed colour slides of interesting or little known species. The regular Monday exhibitions of specimens brought or sent by our members had a growing success, and this is thought to be a very effective means of increasing general knowledge of the fungi. Even during the winter months there were seldom less than twenty species, and not only Myxornyc ete s and lignicolous species. FroIn April to November, those around Faris could see species from the sea shore dunes of Cotentin beside others rno r e or less montane like Caloscypha fulgens or Catathelasma imperiale collected in the Yonne at an abnormally low altitude. The late season furnished an abundance of a recently described species, Hebeloma cylindroporum Romagnesi which was very common in the silicious pinewoods of Ermenonville forest to the North of Paris. The six sessions on introductory mycology conduc te d a stlnjp re viou s years by Messrs. BERTRAM AND ROMAGNESI met the same success, and the practical classes to introduce amateurs to the use of the microscopes were particularly well supported thanks to the devotion of several of our rne mb e r s who wi llingly accepted this teaching task. During the season the SMF organised in the He de France 38 whole day forays on Sundays and 37 half day - mostly on Saturday afternoons, which were well attended. Several interesting species were found there for instance Psathyrella chondroderma, very rare in open country and Clitocybe martiorum Favre for the second time in the forest of Retz (Aisne). Our annual Congress which attracted more than 200 participants among whom we were very pleased to welcome several English colleagues and even some Americans, was held from August 25th to 2nd September at Thonon-les-Bains (Savoie) under the aegis of the local mycological society. Fungal growth was not very good, but, thanks to the efforts of our organisers the members of the Congress were able to enjoy good collecting. Our American friends were particularly interested in Amanita cae sarea which they were able to compare with the American species to which they give the same name, but of which the strpe, almost as thin, as that of our vag inata, and the slender conical cap are completely different. The permanent exhibition which figured many specimens coming from collectors in the region was well stocked and offered us such rare species as Phaeocollybia jennyae. On short private forays made by small groups outside the programme, several species found in subalpine stands of Alnus viridis were collected. such as Russula alne~ Romagnesi and Lactarius alpigenes Kuhner ( = ~Blyth?) On the 5th of October our Paris exhibition was held to the satisfaction of all, since more than 350 species were presented there in spite of the severe drought which one could believe the worst ever. and which discouraged outside visitors. To all these events centred on Paris in 1970. one must naturally add those of all the local societies affiliated to the SMF. too numerous to be described in detail. in particular our local section of the DeuxSevr e s vNo r-d, which was more active than ever. Translation by the Editor. The 1971 Congress of the SMF will be held in Rouen from 2nd to 9th September. Some accommodation will be available in the Cite' Universitaire at a cost of only 18. 50F for bed and 3 meals (£ 1 = about 13F). BMS members may attend by virtue of a reciprocal agreement between our two societies. Details from the local Secy. Prof. B. Boullard, Faculte' des Sciences de Roue n, 76, Mont-Saint-Aignan. Seine Maritime, France. Booking before 31st July please.
