Specimen notes
Public Note:
30th Fungal Foray of New Zealand
Public Note:
[PL] pores adnate, golden yellow, regular oval or round 1-1.3mm. Stipe cylindrical, glabrous, brown, paler than cap. [JAC] Cap 3.4c. Stipe 3.2 x 6mm. Pores 0.5-1.5mm. McNabb says; "may be recognised by the dry, pallid brown to cinnamon brown pileus, yellow hymenophore, and pallid stipe. The presence of basal ([cream to yellow] rhizomorphs appears to be a relatively constant character." This does fit McNabb's concept, except for the cap which is darker than cinnamon and the flesh which stains blue/green (in photo) and the stipe diameter. If this has the same sequence as jac10917 then it is a good candidate for X. lentistipatus and McNabb was in error about the blueing reaction, which is understandable as it seems he did not see fresh material. The most significant difference seems to be the stem scabrosity, and the yellow rhizomorphs (perhaps not always persent). But between lentistipatus, squamulosus, scabripres, if we ignore blueing then there are few real differences. lentistipatus has a thin stem and scabripes thicker. If we assume mcnabb was sure scabripes and squamulosus are different then lentistipatus is probably a synonym of one of them, and squamulosus is the most likely. A direct side by side comparison of the types of squamulosus and lentistipitatus shows that only the furfuraceous cap of the former is distict, and even then the type collection has caps ranging smooth to furfuraceous (although not as distinct as type of squamulosus). Is there a smooth capped version of squamulosus around that is genetically different?
