Specimen notes
Public Note:
stromaticus ? ID ex image in Hemmes. very short substipe, cap finely hairy, more especially toward point of attachment.
P.R. Johnston
Public Note:
C. stromaticus sensu Hemmes is sulphur yellow whereas the type from Australia is described as tan. No descriptions of stromaticus mention crystal encrusted cystidia of the episphaeria group. It seems odd that Egon did not discuss this species. This has thick-walled crystal encrusted cystidia, but the crystals are fragile and spread easily in a squash. 2-3-4 spored, not mentioned by Egon, but the same in every other respect. Clamped. The largest cap size appears to be about 8mm, the cap hairs are 5um diam and thick-walled (which is how it differs from the NZ C. parietalis). Spores 6.5-8um. See also recently described C. flavus which is described by the authors as differing from aureus by "Crepidotus flavus differs .. in basidioma dimensions, less ornamented pileus surface, and basidiospore and cheilocystidial morphology, with C. aureus producing smaller (6-7 µm), subglobose spores and cheilocystidia that are fusoid to lageniform, basally thin-walled and apically thick-walled (≤ 1.5 µm)." Spores of C. flavus are 8.7x8.8, Q=1. Note that Horak's images of the cheilocystidia are not lageniform, but aureus has thic-walled cystidia, as does this, and flavus does not.
