Recognized by sight: “Collections identified as A. delicata are found to be polyphyletic and distributed in four clades. Variation in the presence or absence of a medulla layer in some species, previously a key morphological character, has made it evident that additional characters are required to reflect the genetic diversity in the genus. A new taxonomic character, the schizomedulla, is discussed and shown to distinguish two novel species, A. subglabra and A. scissa, from the morphologically similar species A. delicata. A reticulate, merulioid hymenial surface can no longer be considered a character unique to A. delicata. Furthermore, ITS data from the voucher specimen from which the genome of A. delicata was produced indicates this species is A. subglabra.”

A. delicata is what you have here, characterized primarily by this almost poroid network of anastomosing ridges. A. polytricha is among the more traditional-looking Auricularia, apparently separated from its brethren by the length of the hairs found on the sterile upper portion of the fruiting body’s surface. From what I understand, A. polytricha, A. fuscosuccinea, A. cornea and A. auricula-judae can all be some degree of hairy, and no text I’ve found makes differentiation between them a painless process. One discussion on the finer points of hairy Auricularia can be found here http://mushroomobserver.org/54669.

Of course, you got an easy one. A. delicata hands down.

Isn’t Auricularia polytricha synonymous

to Auricularia delicata at all?
