Observation 64281: Entoloma melanocephalum G. Stev.
When: 2011-03-12
Herbarium specimen reported

Notes: This was an interesting find of this species which is normally found on soil, here it is fruiting directly from rotted wood, another interesting feature is the pigmented cheilocystidia which in these specimens are only located near the middle of the lamellae margin, they are more commonly found along the entire length of the lamellae margin.

There is a slight chance it is an undescribed species although all microscopic characters are a match for the species I proposed and it keys out to that species in E. Horak’s book, his description says that this species is saprobic on soil or among rotted wood or debris, it is a very variable species, especially in colour.

The pigmented cheilocystidia are often very faintly pigmented and difficult to see, I think these are a bit unusual due to rather warm and dry conditions, E. Horak is the expert on the New Zealand Entolomataceae but he doesn’t live here so all I can do is preserve the specimens and make a herbarium deposit.

Very beautiful!

“Leptonias” are magic!
By the way I think that the two features that you’ve mentioned mean it’s a different taxon – changing the substrate means a different set of enzymes, and a different distribution of cheilocystidia is an important microscopic feature. I’d show the specimen to an Entoloma expert to be sure.

Beautiful!
