Observation 52538: Hemimycena cucullata (Pers.) Singer
When: 2010-08-22
Collection location: Thoiry, France [Click for map]
Herbarium specimen reported

Notes: Found under spruce and fir, on wood and duff, moss part of the duff.

The first micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are fusiod, pointed, thick and numerous on a non-fertile edge. No pleurocystidia were obs. Also there was no reactions to Meltzer’s in the tissue or spores.

The second micro-shot is of the cap surface at 400x in Meltzer’s. The cap is a cutis, no gelatin, with lots of pileocystidia. The pileocystidia are finger-like, slightly wavy, with blunt ends.

The third micro-shot is of the stipe surface near the apex at 400x in KOH. There are lots of caulocystidia, finger like with blunt ends.

The fourth micro-shot is spore from the stipe apex at 1000x in KOH. The spores are fusoid, hyaline and smooth. The apr. size is 10 × 3 um.

Putting this all together with the no reactions to Meltzer’s, and lots of cystidia everyewhere, these are Hemimycena, and in Funga Nordica this keys out pretty well to H. cucullata.
