Observation 198160: Entoloma globuliferum Noordel.
When: 2014-11-27
Who: zaca
No herbarium specimen

Notes: During many time I had doubts about the classification of these specimens as well as those in observation 198161, manly because they were found at the same place (a very productive one in Entoloma spp., e.g. those in observation 157808, observation 161805,observation 198094, observation 198101) and looked somewhat similar. However, the micro features are quite different, namely:

- Both have big heterodiametrical multi-angled spores, these ones with mixed nodulose and hyaline and while the ones in observation 198161 only had hyaline spores;
- These ones have a pileipellis with only remanescents of a trichoderme at places with light brown intracellular pigment, while the ones in observation 198161 the transitions to trichoderme are more common and the intracellular pigmentation is very dark brown;
- These ones have non-pigmented sphaeropedunculate cheilocystidia, while the ones in observation 198161 have broadly clavate to broadly ellipsoid terminal elements of cheilocystidia with brown pigment.

I was able to find only one Entoloma sp. with the features mentioned above, and do not belong to subgenus Leptonia – section Cyanula as erroneously I thought initially, but to subgenus Nolanea – section Endochromonema: Entoloma globuliferum.
