Boletus valens is a nom. nov. in Corner’s book, Boletus in Malaysia (1972), p. 161, for B. albellus Massee non Peck. Placed in subg. Tylopilus, Corner’s description of the pileus is “…dark or pale fuscous grey to greyish white, paler on expansion,…”, but his illustration shows a bolete with a brown to brownish gray pileus. Distribution in Malaya, Singapore, Borneo in lowlands and mountains.

Please note that some of those boletes first described from SE Asia occur further north in Asia.

Your specimen is certainly a most viable candidate for DNA sequencing.

“No other book references this species other than the Fungi of Japan. The deep reticulation of the stipe and the colors match it exactly. The fungi did not leave a spore print due to its immature stage of development. The spore size is smaller due to the spores being obtained from the tubes and are, as noted above, at an immature stage of development.”

Don’t believe I’ve ever heard this species name. Has it gone out of style during this past decade? Is this yet another strange inhabitant of that alternative fungal universe called Mingo? :-)
