Dave from tn. Posted May 14 Report Share Posted May 14 Found growing in mulch in Tennessee. It’s been hot in the mid 80s and some rain. All comments are greatly appreciated! Quote Link to comment Share on other sites More sharing options...
michele Posted May 15 Report Share Posted May 15 probably Agrocybe sp. Quote Link to comment Share on other sites More sharing options...
Dave from tn. Posted May 15 Author Report Share Posted May 15 Thx I believe so! Looks more like Agrocybe arvalis to me so far. Quote Link to comment Share on other sites More sharing options...
Dave W Posted May 15 Report Share Posted May 15 If they're Agrocybe arvalis, then you may be able to dig up a sclerotium attached to a stalk, or a rhizomorph. Sclerotia are small bundles of hyphae that some species use to trigger the growth of fruit bodies. Also consider the species A. putaminum.

Dave from tn. Posted May 16 Author Report Share Posted May 16 Kinda stumped now. I went back but couldn’t find any sign of sclerotia on the stalks, in the mycelium or anywhere. 🤔 Quote Link to comment Share on other sites More sharing options...
Dave W Posted May 16 Report Share Posted May 16 I'm not sure if the sclerotia hold together (or disintegrate) after the mushrooms have been in situ for awhile. Or, the sclerotia may be buried a few inches beneath the bases of the stalks... not sure. The thin stalks seem more like what to expect from A. arvalis than A. putaminum. The latter has larger spores. Quote Link to comment Share on other sites More sharing options...
