Strobilomyces strobilaceus
Strobilomyces strobilaceus (Stop.) Berk.
The following description is from Pilat, Mushrooms
Cap thick fleshy, hemispherical, then pulvinate convex, finally rather piano-expanded, 5 to 12 cm. in diameter, rounded, dingy umber brown to grayish blackish brown, covered on the whole surface with dry, large, imbricate and slightly erect, thick scales; margin usually appendiculate with remnants of the velum.
Tubes whitish, then grayish, becoming brownish, becoming dirty red when broken, adnate to decurrent, long. Pores large, angular, whitish gray, then becoming brown.
Stem subconcolorous with the cap, covered at least in its middle part with similar scales as the cap, subcylindrical, mostly smooth below, 7-9 x 1-1.5 cm.
Velum double, the inner one whitish, free, the outer one grown together with the covering of the cap and stem, dark and cracking into scales.
Flesh whitish, becoming first light orange, yellow, then dirty pink,, flesh orange to dirty lilac when cut and exposed to the air, similarly as the flesh (trama) of the tubes, so that the pores redden when bruised and finally turn brown. The consistence of the flesh is drier and more flocconose than in other Boletinae, and is said not to contain boletol.
Spore dust blackish brown. Spores subglobose, with a reticular relief ornamentation, brown, with one gutta, 10-15 x 9-12 lc.
Distribution: In all kinds of woods, but more abundant in deciduous woods, in summer and autumn here and there, and in some years fairly abundant.
Use. Though edible yet much inferior to most Boletineae. Few gather it. The flesh is relatively dry and the appearance of the mushroom is repelling.
Remarks. Though the mushroom is often listed as Boletus strobtlaceus (Stop.) Fr. it is distinguished from the Boletineae proper by the habit of the receptacles as well as especially by its spores which are subglobose and relief ornamented. Boletus has smooth spores, mostly ellipsoid fusiform cylindrical. Thus it is placed today not only in a separate genus (Strobilomyces) but in a separate subfamily Strobilomycetoideae, to which belongs in addition to the genus Strobilomyces also the tropical and North American genus Boletellus Gilb. In addition to Strobilomyces strobilaceus, which grows in the whole of the temperate zone of the northern hemisphere, about 6 more tropical species, most of them distributed in the Congo, belong to the genus Strobilomyces.
Synonyms: Boletus sfrobiliforrnis Vill., B. floccopus Vahl. non Rostk., B. squarrosus Pers., B. slygius Wallr., B. lepiota Vent., and B. strobiloides Krbh.
