Dextrinocystidium Sheng H. Wu 1996 [1995]

Description

Basidiomata resupinate, effuse. Hymenial surface smooth. Dimitic. Generative hyphae simple-septate. Skeletal hyphae occasionally branched, nonamyloid, nondextrinoid. Lamprocystidia present, dextrinoid. Gloeocystidia present. Basidia utriform, four-sterigmate. Basidiospores broadly ellipsoid, verrucose, amyloid.

Latin

Basidiocarpum resupinatum, effusum; superficies hymenialis plana. Systema hypharum dimiticum. Hyphae generatoriae efibulatae. Hyphae skeletales aliquando ramosae. Lamprocystidia praesens, dextrinoidea. Gloeocystidia praesens. Basidia utriformia, 4 sterigmatibus. Basidiosporae late ellipsoideae, verrucosae, amyloideae.

Notes

Etymology. From dextrino + cystidium, referring to the dextrinoid reaction of the lamprocystidium.
Dextrinocystidium is characterized by the presence of dextrinoid lamprocystidia, clampless generative hyphae, branched skeletals, utriform basidia and verrucose basidiospores. Scytinostromella also has branched skeletals and basidia of a similar shape, but lacks the dextrinoid and cyanophilous lamprocystidia. Moreover, Scytinostromella is a clamped genus, with loose texture in the subiculum, and has much smaller basidia and basidiospores.
