[GS] Pileus 2-5-4 cm. diam., dry, light brown, surface fibrillose floccose, velvety when young; cuticle of interwoven hyphae; flesh soft, creamy, becoming slightly pink when cut. Pores variable in size, up to 2 mm. diam., tubes 4 mm. long, dull yellow, depressed round the stipe; hymenophoral trama divergent. Stipe 4 cm. x 3-4 mm., tough, unequal, pale fawn at top, darker or white at rooting base, some with attached rhizomorphs; flesh fawn coloured. Spores 10-12 x 5um ,light brown, with moderately thick walls indistinctly marked with broken longitudinal ridges. HABITAT:on fallen Nothofagus solandri in the Hutt Valley, 8.6.1952, P. Boszcell, and at Puramahoi, Nelson, 20.4.1955, Dorothy Read. One species possibly close to Boletellus lentistipitatus has been described from New Zealand by Heim (1951) though not yet with a full valid diagnosis. It is Boletus paradisiacus, a small species with a brown cap covered with tufts of fine black velvety tomentum, large pores in an orange-yellow pore layer which is depressed around the stipe. A tuft of yellow rhizomorphs is carried at the base of the slender stipe. The species was collected in Nothofagus forest at Paradise, Lake Wakatipu. [RFRM] PILEUS: convex to plano-convex, 2-4cm diam., dry, finely felted to subtomentose, pallid brown to cinnamon brown; cuticle a trichodermium, composed of erect, branched, septate hyphae 7-14 um diam., with brownish contents; margin entire. HYMENOPHORE: tubes to 4 mm long, excavated around apex of stipe, dull yellow at first, becoming darker yellow at maturity; pores concolorous with tubes, large, angular, to 2 mm diam. STIPE: 2-4 cm long, curved, more or less equal, 2-3 mm diam., solid, fibrous, dry, finely granular to furfuraceous by aggregation of caulocystidia, pallid fawn to creamy yellow apically. brownish basally; annulus absent; cream to yellow basal rhizomorphs often present. SPORES : spore print not obtained; spores pallid melleous, elliptic-subfusiform, 10.2-14.3(16.3) x 4-4.9(5.5) um. smooth. HYMENIUM: basidia hyaline, clavate, 28-37x7.5-12um, 4-spored; cystidia sparse, scattered, hyaline, thin-walled, subcylindrical to ventricose-rostrate, 36-56x7-12.5um. HYMENOPHORAL TRAMA: bilateral, of the Phylloporus subtype; clamp connections absent. CONTEXT OF PILEUS: sordid white to cream, turning faintly pink on exposure to air or unchanging. SMELL: not distinctive. Notes. There are a number of differences between the original description and that given above. The most important of these is that spores of the type specimen are smooth-walled and not indistinctly marked with broken, longitudinal ridges as described by Stevenson. Furthermore, the spores figured by Stevenson (fig. 2a) do not belong to Xerocomus lentistipitatus, and it would appear that the spores of this species and Tylopilus niveus G. Stevens, have been interchanged in the illustrations. From their size, shape, and ornamentation, the spores figured with T. niveus on p. 382 represent Stevenson's interpretation of the spores of Xerocomus lentistipitatus. The short, smooth-walled spores and hymenophoral trama of the Phylloporus subtype indicate that this species belongs in the Boletaceae rather than Strobilomycetaceae. It readily fits within Xerocomus, but in the absence of information on the ammonia reaction of fresh pilei it is not possible to assign it to one of the sections recognised by Singer (1962). X. lentistipitatus may be recognised by the dry, pallid brown to cinnamon brown pileus, yellow hymenophore, and pallid stipe. The presence of basal rhizomorphs appears to be a relatively constant character. [JAC] the type has no basal rhizomorphs. The spores are smooth. No hymenial cystidia observed. With hymenial oleiferous hyphae. Pileipellis a trichoderm of large oliferous hyphae and cylindrical/clavate terminal cells. Material exuding oil drops into melzers/KOH. Spores length=10.0–13.1µm (µ=10.9, σ=0.77), width=4.3–5.3µm (µ=4.9, σ=0.33), Q=1.9–2.7µm (µ=2.25, σ=0.21), n=20. Slightly dextrinoid. Pat Leonard has PL10115 as X. lentistipitatus, same as JAC10917 which I identified as X. squamulosus and sequences in that group, and with flesh staining blue/green. Presumably Pat's material did not stain blue, indicating a variable character. That would leave the apical stipe colour and presence of rhizomorphs to separate them. The type does not seem to have any rhizomorphs, and although Stevenson mentions rhizomorphs she does not say what colour. The type of X. squamulosus shows yellow hyphae at the stipe base.The only other collection seen by McNabb was PDD25253. A direct comparison of the two types suggests perhaps the furfuraceous cap of X. squamulosus is a separator. There is a possibility X. lentistipitatus is an earlier name for X. squamulosus but it is preferable to keep the name separate just in case a non-staining, yellow rhizomorph Xerocomus squamulosus look-alike does turn up (and is not also X. scabripes). Note that Horak has two collections under this name with images ZT69-121 and ZT68-169, neither deposited in PDD.
