Notes: Mycena conicola Stevenson (29 D) Fig. 4 = Mycena aff. flos-nivium Kuhner
The type is poorly preserved but nevertheless several important details were
obtained. According to these characters this fungus approaches M. flos-nivium
which grows in Europe on rotten cones os spruce from late winter until spring.
The New Zealand material was collected at the end of June, on cones of spruce.
The structure of the cuticle and size and shape of the cheilocystidia and spores
(110.-12 X 4.5-5 µ) support this identification. It is recommended that M.
conicola be regarded as a synonym of M. flos-nivium and added to the list of
exotic fungi in New Zealand.
