Scleroderma under Carob tree - verrucosum?

Hello I have met this scleroderma and I assume it is S. verrucosum from its eggshell-thin peridium, leopard pattern on a faint yellowish-cream background, small size (2-4cm across). What does not fit is the absence of a pseudostipe, and the spores are a bit on the smaller size (7.5-9.5 um, averaging 8.3 um).
