Book Updates

Check back for Dr Beug's notes on new mushrooms he has found, or perhaps a mushroom whose DNA sequence has exposed a new discovery or resulted in a name change. All updates will include the page number and key lead numbers where the species would have been placed if included in the book.

Update #1 - April 7, 2021

Yes, the book has not even been published yet, but mushrooms are on their own schedule. I found these after we went to print.

Page 30 10c. “Xerocomellus” mendocinensis is very similar to members of the Xerocomellus diffractis group. It varies from almost blackish to olive-tan and the flesh in the cracks of the cap is tan. It is edible but with little flavor. It fruits in the fall under both oaks and conifers. KOH turns the flesh orange and the cap black.

Page 33, lead 16b. This is the green form of Suillus ponderosus

Page 148, lead 191b Leucoagaricus erythrophaeus is an uncommon small Leucoagaricus species (cap <2.5” wide) that rapidly stains red-orange in all parts and then slowly turns dark brown. It grows mostly on the coast in mixed forests and is known from parts of the Cascades. It fruits in the fall. The edibility is unknown. Compare to Lepiota flammeotincta, a species where only the cap and stipe but NOT the gills instantly stains red-orange and then slowly turns dark brown.

Page 228, lead 326e Nolanea cf strictior is a conic to bell-shaped hygrophanous species with a cap (<2.5” wide) that that is dark brown when moist, fading to brownish-orange when dry. The gills are pallid when young. It fruits spring-fall under both hardwoods and conifers and has an indistinct odor and taste. The edibility is unknown. Nolanea verna is very similar in coloration and fruiting but the young gills are brown, and the spores are smaller.

Update #2 - April 28, 2021

Receiving what turns out to be a rare species of fungi from a friend is always a delight. This tuber named after Daniel Luomae was found in the Snowden area of Klickitat County, WA under a Douglas fir tree. It is one of only three Tuber species known from the PNW with spiny spores - and the other two are both associated with oaks. The mycorrhizal association is correct, the color is correct, the spiny spores are there, and it has distinctive inflated cells in the cuticle. The last step is to dry and voucher the sample and send it off for full DNA analysis.

Announcement of this new truffle species in Science News (April 2020). Paper describing Tuber luomae on Research Gate (December 2020).

Page 94, part of the 102a-d - key leads. Microscopically Tuber luomae it is similar to Tuber candidum (one of three spiny spored Tuber species) but associated with Douglas fir, while the other spiny spored species are associated with oaks.
