Specimen available

Ok, another G. vittaeformis, but this one with the larger spores, making it form vittaeformis.

The first micro-shot is of the gill edge in Metlzer’s at 400×. There are the fusiod-ventricose cheilocystidia, and the dextrinoid spores. Sources claim there is a difference in the cystidia between form vittaeformis and form tetraspora, but I’m not that sure.

The second micro-shot is of some spore on the stipe apex in KOH at 1000×. The spores are wrinkled, and pointed, although with the stipe hyphae bluring things you can’t really see the plage. The ave. spore size on seven spores is 11.3 × 6.8, which puts this one into the form vittaeformis camp.

Compare to obs. 7310 for form tetraspora. (Like there looks to be any difference…)
