Specimen notes
Public Note:
New record for New Zealand. Discussion with Megan Romberg at MAF on the reason I didn’t originally record as S. thomasianum was as follows …
Ellis & Ellis, Micro-fungi on Land Plants lists only S. carthusianum (0-3 septate), and the plate (524) shows one conidium like mine, with others showing 2-3 septa and straight or curved. Martin Ellis’ inclusion of it appears to be based on a collection at Kew made by R.W.G. Dennis who published it in Kew Bulletin, Vol. 25, No. 2. (1971), pp. 335-374. Dennis’ notes say… “In view of the great variability in size and shape of the conidia it seems likely that Marssonia thomasiana (Sacc.) Sacc. subsp. fautreyana Sacc. in Bull. Soc. Mycol. France 16: 23 (1900) on the same host, may be a synonym, in spite of the narrow spores cited for it.” I decided that E&E S. carthusianum was the best candidate, and that E&E had effectively synonymised the two based on Dennis comments. However, I did not read past M. thomasiana to the ‘subsp. fautreyana’ ! I can find no further trace of this subspecies in the literature I have. I also saw Dave Farr’s evaluation … Mycologia, Vol. 85, No. 5 (Sep. - Oct., 1993), pp. 814-824 and he does distinguishes the two, although his figure 10 has quite a variation in conidial morphology. On finally obtaining a copy of B. Sutton and F. G. Pollack. 1974. Microfungi on Cercocarpus. Mycopathol. Mycol. Appl. 52: 331-351 I decided that there are indeed two taxa and the name S. thomasianum should stand. Reported to MAF 2/07/2010. Sent to MAF.
