Collybia incarnata G. Stev. 1964

Description

K(M) 235260. Stevenson 1262. The material has dried yellow. The spores exhibit great variation. The immature spores on the gill (attached to sterigma) and the stipe are long, mature spores on the gill are shortened but retraction nearly impossible to see, whilst the spores on the cap exhibit the usual form for Rhodocollybia with a dextrinoid retracted endospore and outer wall sometimes collapsing. The result is a great variation in possible spore measurements, as seen in the recent NZ collections. However, without doubt a Rhodocollybia.
