this form was described by Kobayasi in 1973 from Papua New Guinea along with two others (A. delicata f. purpurea & A. delicata f. delicata), all of which appear to have been sunk into synonymy with A. delicata (though in what subsequent publication, I’m not sure).

Kobayasi’s 1981 article, “The Genus Auricularia”1 (the original 1974 article in which f. alba was described has proved difficult to track down) has only this to say about A. delicata f. alba:


16. Auricularia delicata (Fr.) Henn. f. alba Y. Kobayasi
BNSM 16(4): 645 (1973) et JJB 48: 226 col. pl. 10 (1974).
The albinic strain. Type loc. Baiyer River, New Guinea.
Distr. Rabaul and Oksapmin, New Guinea.1


Admittedly, I do not have a comprehensive knowledge of Auricularia literature. Perhaps there is mention of albino, delicata-like species other than Kobayasi’s New Guinean “f. alba” in other publications, but if they exist, I have not seen them. If the reports of such white Auricularia are as limited as they appear to be, I find it surprising that something so curious co go unseen and unconsidered for so long. Shua may be able to provide some clarification here.

edit: Let us also remember that color is extremely variable in Auricularia spp., and is therefore of little diagnostic value in determining species. there does, however, appear to be a difference between material whose paleness is due to age and/or bleaching by sun exposure or rain, and the young, firm, stark white FBs seen in this and other observations.
