Danny’s DNA Discoveries – Tricholomatineae Incertae Cedis of the PNW
|
Introduction
These are in uncertain families of the suborder Tricholomatineae. They may each get their own families (seems likely), or they may be placed in an existing family. Nothing much unites these yet morphologically. abundant common uncommon rare - colour codes match my Pictorial Key and are my opinions and probably reflect my bias of living in W WA. Rare species may be locally common in certain places at certain times. Click here to download the FASTA data of all my DNA sequences |
Summary of Interesting Results
|
![]() One of our largest gilled mushrooms, a huge funnel-shaped clitocyboid up to 40cm across. Clitocybe maxima and Infundibulicybe geotropa may also get large. Unpleasant odor and taste. Formerly in Leucopaxillus because the gills separate easily, but although large, these are not as dense as Leucopaxillus. Amyloid spores. Species mentioned: Aspropaxillus giganteus, septentrionalis. |
![]() 'Cleistocybe' gomphidioides WA - this clitocyboid with a veil can be told apart from Catathelasma and true Cleistocybe by viscid cap, growth in fall, and a sometimes fleeting veil/ring, making it very hard to ID if you don't notice it. Strongly rancid-farinaceous. True Cleistocybe, such as Cleistocybe vernalis have a dry cap. This species needs to be moved into a new genus and family. |
![]() A newly erected genus for Hertzogia martiorum, formerly in Clitocybe and Lepista. It has true cystidia (unlike Clitocybe), pale pink smooth spores, a somewhat pinkish-orange cap and stem with a hoary white coating and strong farinaceous odor and taste. Species mentioned: Hertzogia martiorum. |
![]() Recognized by round spores with warty nodules, but otherwise a nondescript omphalinoid/clitocyboid with an indented hygrophanous cap that may be striate, somewhat decurrent gills and somewhat farinaceous odor and taste. Species mentioned: Omphaliaster asterosporus, borealis. |
![]() Orange, strongly funnel-shaped clitocyboids with close/crowded gills and almost round spores that are off-white and finely warty (like Lepista, the name given to some Clitocybe species with similarly coloured warty spores). Bonomyces is stockier and smells farinaceous and has smooth, elliptical spores. Infundibulicybe gibba is pinkish tan but not as orange, and has smooth, white spores. Species mentioned: Paralepista flaccida, gilva, inversa |
![]() Not only are they hard to tell from other genera (and even mushrooms in other families) they don't look anything alike themselves. They were separated from Clitocybe by having amyloid spores and cystidia along with the similar Pseudolaccaria, but some European authors say both segregate genera lack cystidia so at best the cystidia are hard to find and there are no good separating characters besides this being one of the many genera that, unlike Clitocybe, have amyloid spores. Species mentioned: Pseudoomphalina angelesiana, intermedia, kalchbrenneri. Neohygrophorus angelesianus. |
![]() Stemless oysters on moss with rudimentary or no gills, usually white. They are difficult to distinguish from some Arrhenia species (usually not white) and also Muscinupta (white with a tapered fluting "stem"). It's possible they belong in the Omphalinaceae, but we'll see. Species mentioned: Rimbachia arachnoidea, bryophila, neckerae |
![]() Clitocyboids with a pale brown spore print and roundish, warty spores. The mushrooms have white and pink colours, and the caps and stems are fibrillose. Note especially that this is not white spored! Species mentioned: Ripartites tricholoma. |
