Observation 119360: Lepista (Fr.) W.G. Sm.
When: 2012-12-03
Herbarium specimen reported

Notes: Two basidiomata growing from soil close together in Bosque Estatal de Piñones (along Route 87 between San Juan and Loíza) in woods dominated by the She-Oak Casuarina equisetifolia. This tree is native to Australia but it is much planted and naturalized in Puerto Rico. A good spore print was not taken, but staining in the wax paper bag which held the collection suggests the spores are rust-brown. Spores are ellipsoid and distinctly pustulate. 20 spore average was 6.1 × 3.8 microns with a Qm = 1.60. See photomicrographs.

Something related to Lepista/Clitocybe according to DNA ….

… this species is not identified in GenBank. Maybe some interesting work for the future.

Verrucose spores

I’m not aware that Hebeloma would have such pronounced “warts” as the ones from your photograph, but I don’t know if they are out of range. The gills in the photo look a little brown (like they would maybe produce brown spores?) and you describe a spore deposit in the wax paper bag as brown which might suggest something other than Clitopilus.

do Hebeloma typically have such pronounced warts? I thought they are more finely verrucose. I don’t know … maybe Hebeloma. Puerto Rico always results in hard to ID specimens. At least for me.

Some Clitopilus are definitely warted.

I’m looking at diagrams of Clitipilus spores in “The Entolomataceae of Tasmania” by M. Noordeloos and G. Gates (which includes a chapter on Clitopilus as presently defined) and the spore diagrams of some “clitocyboid” species look just like this.

I think we normally refer to this as warted. Clitopilus should have striate spored, logitudinal from apiculus to apex. Warted kinda give you maybe Cortinarius here, but that doesn’t quite look right. They look more like Hebeloma, but the spores are almost too warted for that. You can check how viscid that cap is, and look for cheilocystidia on the edge.
