and perhaps a minor variation of the spore size, I believe S. texense is the same outward color as S. citrinum.
Arora in Mushrooms Demystified says of S. texense (under S. geaster) that “S. texense (=S. furfurellum) is a very similar, thick-skinned specis with a scalier (often shinged) exterior and thick-walled hyphae in the peridium; it has a more southerly (tropical and subtropical) distribution but also occurs on the west coast.” I believe the mention of the wart size and spore size comes from Kuo’s Scleroderma key. The only major visible difference between the species is the size of the warts: 2mm (or higher), likely T. citrinum; warts less than 2mm tall, S. texense. Parts of Europe have been having some pretty dry and hot weather recently. I think that might favor S. texense as well, but that’s just a guess. Scleroderma is one of the easier mycorrhizal fungi to cultivate, and is widely associated with many tree and shrub species. Any association with ornamental plants from the U.S. could see the introduction of this species and a mycorrhizal hitchhiker.
I agree that the scales do not reach the levels described in books. However, this one is distinctly yellow/citrine and I believe that in Germany, there is only s. citrinum with that feature. I am not sure s. texense is present in Europe.
Sporocarp seems to be well-within Scleroderma fruiting bodies known range. But the scales do not seem to reach the level of S. citrinum, which should have warts. I see what seem to be flattened scales, but they do not seem to rise to the level of “warts.” In Smith, Smith & Weber’s “How to Know the Non-Gilled Mushrooms”, p. 250, in the key 4a regarding S. citrinum it states: “Peridium distinctly scaly, the scales often with a central wart; peridium not dehiscing stellately. Fig. 281” Without distinct warts on the peridium, the photos appear to match more closely the description of S. texense, which has flattened scales and lacks warts.
about 3-4 cm in diameter. The color is indeed yelowish/citrine, although it does not appear clearly on the photo. Odor is unpleasant.
this is not S. citrinum. The warts are not tall enough. But more information needed for identification. Approximate height and width of sporocarp?
