Observation 121160: Entoloma Fr. ex P. Kumm.

When: 2012-10-04

Collection location: Bedford, New York, USA [Click for map]

Who: Linas Kudzma (baravykas)

Specimen available

Abundant fruiting in grass/moss under Oak and Maple. This is from the exact same location as Obs 104507 collected earlier in the year during a very dry part of the summer. This collection was during a period of heavy rains and these specimens were wet and very fresh. I suspect that this may be the same species as collected earlier. More microscopy will be needed to be certain. Spores are measured in the last image using Piximetre 5.3. Info about this useful free software is at: http://boletales.com/...

I find it exciting rather than frustrating that making these identifications are so difficult. It shows how many discoveries are waiting for the serious researcher. I have 12 Entolomas on MO, which even with good ITS sequence data, I still can’t identify confidently.

I’d say

with a 97% match it’s neither lividoalbum nor sordidulum, but another, not yet with any published sequence – or undescribed (which is also quite likely..).

Also close to lividoalbum …

97% match to UDB015863 Entoloma lividoalbum in UNITE. This is what it looks like the most to me.

It is interesting how DNA is not giving conclusive answers. Apparently, too little reliable data in the databases. Often the closest matches are for unidentified environmental mycorrhizal sequences. Especially for my Inocybes.

Irene, the best match in UNITE is ….

97% match with UDB015715 Entoloma sordidulum collected in Estonia. It does look somewhat like the photo associated with this record in UNITE.

I will do this …

I am presently traveling (working in Puerto Rico) and can not give the data my full attention. I’ll look at other databases next week.

Indeed it seems that Entoloma sequence data in Geneank is very incomplete. It’s a funny thing that of the 16 Entolomas I had sequenced by Dr. Alvarado, the most confident ITS match was for my Obs 119831, which I collected absolutely the furthest from my home in the USA!

It’s a shame

that sequences of so many Entoloma species are lacking in the databases..
How distant is this from lividoalbum if you run an analysis in UNITE?

ITS sequence data says close to E. sinuatum, but not exactly (95%).

DNA also says this is identical to my Obs 104507.
