Diaporthe samaricola - Spore Sizes & Appearance.
Peter Thompson, 14-09-2012 13:49
Hello Everyone,

I wonder if anyone has illustrations and measurements of the ascospores of Diaporthe samaricola, which grows on the seed cases of Fraxinus excelsior.

There does not seem to be any information in the literature available to me.

Thanking you in anticipation,
Peter.

Re : Diaporthe samaricola - Spore Sizes & Appearance.
The name Diaporthe samaricola was proposed by W. Phillips & Plowright in 1876 with the following diagnosis: "Perithceia minute, immersed, covered by a circumscribed thin black stroma, variable in size and outline; ostiola minute, prominent; sporidia biseriate, colourless, quadrinucleate, somewhat acuminate, .0007 in. x .002 in.; asci .003 x .0004 in. On the samari of ash, Terrington, Jan. 1875. Plate 42, fig. 6. a. ascus; b. sporidia" [Grevillea 3 (27): 126. 1875].
Lewis Wehmeyer in his monograph of the genus published in 1933 writes of this species on pages 77 and 78 (see attachment: EXTRACT etc.; see also the attachment: 1932-v17-237-0001).
