Who: Douglas Smith (douglas)

No specimen available

Found by Bharati, in a swampy area in grass.

The first micro-shot is of the cap surface at 400x in Meltzer’s. The cap is cellular, without gelatin, no pileocystidia.

The second micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are very random, from clavate to lageniform, with a long wavy neck in some. There was no pleurocystidia obs., and the basidia appeared to be all 2-spored. There were no reactions to the reagent obs. in all tissues.

The third micro-shot is of spores from the stipe apex at 1000x in KOH. The spores are smooth, ellipsoid, with a clear germ pore. The apr. spore size is 11 × 6 um.

Tried to key these out using Flora Agaricina Neerlandica vol. 6, and they weren’t in there. Looks to be an undescribed species really. Prof. Desjardin found another collection the next day of these, and they were in better shape, with rugulose, non-striate very pale caps. He was rather protective of his collection, and did his own write up on those and put that collection in the SFSU herbarium.
