nomenclature has been a quagmire of confusion for years. H. tessulatus is a smallish brownish mushroom that is frequently cultivated and is available in Asian grocery stores. H. marmoreus usually has a water spotted cap and often fruits in large clusters. It is in several books as H. tessulatus. H. ulmarius lacks the water spots and sometimes has a cap cuticle which cracks forming flat scales or patches. This photo may be H. ulmarius but the fruiting appear to be old so it is hard to tell for sure.
