Which crepidotus

[CapAndBracket]

Found today growing on old reeds (marsh land) though some nearbye on
nettles, The best match appears to be Crepidotus versutus. (Jordan)






X1000 four spores on basidia.


X1000 cystidia definately clavate (club shapped).


Cheers J.P.

hi J.P.

other possibles can be knocked out by the marginal cystidia and the amygdaliform (almond-shaped) spores; so you can lose variabilis, cesatii, caspari (same as subtilis), subverrucisporus; there is no hint of yellowing so luteolus can be eliminated as can wakefieldiae and a number of others on fruit-body colours

so Crepidotus versutus seems a pretty good candidate to file it under (this is what appears as C. pubescens in earlier books) - do you have any shots of the spores (plus measurements) J.P.?

best wishes

The specimens are sat on a glass slide for spore drop.

Cheers J.P.

Certainly got a good spore print.


X1000 in water.

These seemed to average approximately 10x4 which is a tad narrow from book description
(maybe my scale), but shape and length are consistent with Crepidotus versutus.

hi

I would dry the specimen and label the packet it as c.f. versutus; I think the only other (remote) possibility is Crepidotus epibryus which has been named and moved from genus to genus on numerous occasions (= among others "Crepidotus herbarum", "Pleurotellus graminicola"); this has characteristically narrow spores rather like yours and would be something you would expect on stems like those you found this on (but the spores are never wider than 3.5 microns)

epibryus is synonymised with Crepidotus pubescens in the sense of Kühner & Romagnesi (1953); versutus is synonymised with Crepidotus pubescens in the sense of Watling and Gregory (1989) so you can see the confusion - Crepidotus pubescens in the sense of Pearson (1949) is Crepidotus luteolus - but your fungus is not that

cheers
