Botany Outing Report: Fungi and Soup, Nov 19th, 2018

Botany Group Report  : November  19th Outing Tsolum River Road

The range of fungi for later November was still large.  Of note we identified many large Russula brevipes – short- footed russula- that heaves up moss, turf, branches etc. ( see photo + slug). We also found one Russula xerampelina  – shrimp russula  (specimens of which were in the soup).  We saw lots of Inocybe species, and the Hypholoma fasciculare – sulfur tuft – in its various stages from young button to degraded soggy  brown “mush”.  Curiosities included the Pseudohydnum gelatinosum  – cat’s tongue (see photo)  and Nidula candida -bird’s nest fungus.  I failed to find a specimen of Xylaria hypoxylon – carbon antlers, so see attached photo taken on the Tuesday.  Also, another intriguing late fall fungus that eluded me on Monday (Jocie not being with us!)  was the Auriscalpium vulgare   “earpick fungus” .   It falls into the tooth/spine morphological group and is another example of a fungus with very specific environment – Douglas fir cones – see attached photos.

Lactarius w orange latex                                        Russula brevipes

The Lactarius that we found near the end of the walk turns out to be Lactarius aestivus,   not in Truedell and Amirati (where it would still be subsumed under Lactarius deliciosus var. deliciosus.)  It was larger than the Lactarius subflammeus, of which we saw hundreds, and much more robust, with orange (not white) latex (see photo).

Here is the general entry on L. aestivus  from Matchmaker ( no photo however) :

Features of Lactarius aestivus include 1) viscid, orange, zonate cap, 2) subdecurrent to decurrent, crowded, orange gills, 3) orange and whitish stem that may be scrobiculate, 4) scanty bright orange milk, 5) grayish green staining of some parts (but not extensive and conspicuous), 6) fruiting under true fir and hemlock.   (scrobiculate means pitted with indentations , in other words it is not a smooth straight -sided stalk).  All these macro characteristics fit.   See photo  attached.

It is well illustrated and described in Siegel and Schwarz “Mushrooms of the Redwood Coast”  and they note that in their opinion it is the best tasting of the “deliciosus” group.  It is less grainy and firmer, which is my experience.  I did pick and cook up more caps (the stipe is too tough).

Next Gathering : Christmas Potluck lunch  Monday Dec. 10th, 12.30 pm
