Appearance
The summer cep's fruiting body is a mushroom with a swollen bulbous stem, and large convex cap. The cap is more or less round and usually up to 20 centimetres in diameter. It bears a velvety brown, rust to chocolate cuticle which when dry often cracks to reveal the white flesh underneath, giving the appearance of a net.The darker, more uniform shade and the velvety feel of the cap are a key feature distinguishing this species as is the vagueness or total absence of a white edge to the cap margin as seen in "Boletus edulis". The tubes and pores of the hymenium are initially white, darkening with age to pale yellow and finally brown. The stipe is central cm in height) and has a strongly marked reticulated pattern with a variable white to brown colour.
The flesh is white and thick and remains firm if yellowish as the mushroom ages, and is often attacked by insect larvae. Its odour is pleasant.
Distribution
The summer cep is found in woods throughout Europe, after hot and humid weather, from the start of summer until the end of autumn. It is particularly common in the south and west of France, as well as in Tosco-Emiliano Apennine in Italy. It is less host-specific than other porcini mushrooms. It occurs in Ukraine and Crimea, and Republic of Karelia, Karachay-Cherkessia, Krasnodar Krai, Tula Oblast, Moscow Oblast, and as far east as Primorsky Krai in Russia. "Boletus reticulatus" has been recovered from southern Africa, where it was likely introduced, growing under the Mexican species "Pinus patula".Habitat
