Synaptospora plumbea ?
Eduard Osieck, 19-09-2015 20:06
On the same Alnus branch with Dimerella pineti (so far 7 fungi species noted) also half immersed (some erumpent), scattered, black ascomata (ca.0,4 mm) with a "bumpy" ascomatal wall (= "roughened"?). Spores one-celled, ellipsoid, hyaline becoming brown with often two drops, 9-10 x 4-5 um. Asci cylindric with apical ring, uniseriate, presumably unitunicate, spore bearing part 65-75 x 5-6 um. Paraphyses 3-5 um wide, septate.

This description fits Synaptospora plumbea quite well, but what about the brown hyphae shown on one of the pictures? Could these be part of the basal mycelium (mentioned in the Helminthosphaeriaceae key in Miller et al. 2014)?


The ascomata are descibed by Huhndorf et al. 2004 as "superficial", does that exclude erumpent ascomata (cf. figure 1 in that paper which appears to show half immersed ascomata)?


The key question is whether the collection belongs to the Helminthosphaeriaceae. Are there other taxa outside this family with similar features (e.g. Baermaellia but perithecia in a brown stroma and the species with germ split longer spores)?


Help much appreciated!
