本文描述了产于中国西南部的一种块菌-云南块菌（Pious yunnanensis）的一新种-脐块菌（Tuber umbilicatum）。子囊孢子椭圆形，具乳突，基腔脐状，具小刺，短脊相连，形成蜂窝状网，网径6-8目。本文提供了7种具刺网状孢子的块茎植物检索表。
Tuber umbilicatum, a truffle associated with Pious yunnanensis in southwestern China, is described and illustrated as a new species. It is characterized by inconspicuously papillate ascomata with an umbilicate basal cavity and ellipsoid ascospores ornamented with spines connected by low ridges to form an alveolate reticulum 6-8 meshes across the spore width. A key to seven Tuber species bearing spinose-reticulate spores is presented.
