Black lump and yellow webcap - that's what stands before your eyes after several days of forest fermentation in mid-September. A lump in a basket, a webcap in the forest. I'll have to try the other way around somehow. It is interesting to get acquainted with the yellow spider web from the culinary side, but of course, it is not possible to collect both abundant mushrooms at the same time. You have to choose.
