Dave up in NNSW was finding these ‘King Stropharia/Stropharia rugosoannulata’ growing in cow manure that were often white or bone in colour.
The collection was sequenced and the results at that time were equivocal and confusing – it seems likely that they were not actually Stropharia rugosoannulata but despite asking some BLASTn wizzes for advice we were none the wiser.
However two new sequences from Pakistan of a new species – Stropharia atroferruginea – seemed a reasonably close match which at least suggest these may not be rugosoannulata.
Edibility? Unknown… All photos: Dave
