New Names for 2001

Agrocybe pediades - It's surprising that we haven't reported this species before since it is common in California grasslands.  It's prior absence may be due to people being too busy looking for larger species in the past.  On the other hand, it may be due to the warmer, drier weather that we had prior to this year's fair.

Amanita ``bonnydoonensis'' - This is a new local name for an Amanita species that we occasionally see in the sandy soil typical of Bonnydoon, CA.  It is refered to as A. baccata in Mushrooms Demystified, but this is a European name which Rod Tulloss does not believe is appropriate for our local species.  I believe collections of this species have been send to both the SFSU herbarium and to Rod Tulloss.

Amanita ``calyptraderma'' (spring form) - a.k.a. Amanita ``calyptrata'' (spring form).  This mushroom grows in late winter and spring, has a lemon yellow cap usually with a large distinct volval patch and a sack-like volva.  It grows with live oak in coastal California or pine in the Sierra.  It is closely related to another Amanita species which is common in California.  The relative grows in early fall, has a brown-orange cap usually with a large distinct volval patch and a sack-like volva.  It typically grows with madrone in California.  Unfortunately, the taxonomic history is far less clear than the distinction between the species.  Both species are most often referred to as Amanita calyptrata Peck.  However this name is invalid since it was applied to a European species prior to Peck's application.  Murrill corrected this and introduced the name Amanita lanei Murrill.  The problem is that the type collection for this species was described by Peck as being green in all parts.  The name Amanita calyptraderma was applied nine years later by Atkinson to one of the two species, but it is not clear to me which.  I have somewhat arbitrarily taken to calling the fall species A. lanei since the only clear application of that name I can find is in Lincoff's Audubon guide to mushrooms.  Since the name A. calyptrata cannot be used this leaves A. calyptraderma for the spring species.

Boletus amygdalinus - An infrequent early fall bolete.

Boletus barrowsii - An infrequent late winter, early spring bolete that we find under live oak.

Chalciporus piperatoides - An early fall bolete more commonly found on the Northern California coast.

Clitocybe candicans - A new name applied to an unfamiliar small white Clitocybe that was collected on the Sonoma coast.

Clitocybe flaccida - We have referred to this in the past as Lepista inversa = Clitocybe inversa.  We started using this name this year based on a recommendation from a member of MSSF.

Coprinus radiatus - A small, dung loving Coprinus.  Symbolic of how hard we were looking for species this year.

Cortinarius cedretorum - Matched the description given in Mushrooms Demystified.

Cortinarius laniger - Matched the description given in Mushrooms Demystified.

Crucibulum laeve - Another indicator of hard searching.

Dacrymyces palmatus - Interestingly this year this species was far more common than it's look-a-like Tremella mesenterica.  I'm surprised we haven't listed this species in past years.

Entoloma cinereolamellatum - A new name from Largent's Entolomatoid Fungi of the Western United States and Alaska.

Helvella leucomelaena - An unusual find.

Hypomyces sp. - This may have been young H. luteovirens.  It was attaching a Lactarius and was pure white.

Inocybe bakeri - We let Bill take care of the Inocybes.  What he says goes.

Inocybe kauffmanii - See above

Inocybe subochracea - See above

Inocybe whitei var. whitei - We have previously just called this Inocybe whitei.  Bill is happy that my software now supports variety names.

Leocarpus fragilis - A fairly common slime-mold which we usually leave in the field since it's hard to collect.

Leotia viscosa - This came from the Sonoma coast.  I'm surprised we haven't listed this in the past.

Melastiza chateri - A cute little cup fungi that Henry identified in Mushrooms Demystified.

Mycena tenerrima - A cute little bark Mycena described in Mushrooms Demystified.

Phaeocollybia californica - This came from the Sonoma coast.  It matches the description in Mushrooms Demystified.

Phallus hadriani - A happy, but stinky surprise.  This species is fairly rare in the Santa Cruz area and usually only shows up in the summer or early fall in watered gardens.

Pluteus petasatus - Brought in from the east San Francisco Bay by some folks from the San Francisco group.

Poria corticola - Yes, we were even taking the time to identify Poria species!

Ramaria invalii - One of those little Ramariae listed in Mushrooms Demystified.  Yes, we measured the spores.

Rhizopogon rubescens - Matches the description in Mushrooms Demystified.

Rhodocollybia oregonensis = Collybia oregonensis.  This came from the Sonoma coast where it is found infrequently.

Russula blackfordii - Applied by Mark using Thiers key in the Agaricales of California.

Russula paxilloides - Applied by Mark using Thiers key in the Agaricales of California.

Russula rhodopoda - Applied by Mark using Thiers key in the Agaricales of California.

Thelephora multipartita - This came from the Sonoma coast and is another indicator of some hard searching.

Tricholoma aurantio-olivaceum - We finally have a name for this little brown Tricholoma that we get from the Sonoma coast.  The name came from Shanks work in the Agaricales of California.

Vascellum pratense - The most common puffball this year for some reason.
