Observation 75588: Baeospora myosura (Fr.) Singer
When: 2011-09-04
No herbarium specimen

Notes: I realize this species proposal is one which is reported as a western NA type. But niether is the Douglas Fir tree in my back yard typical for this area.

Spores amyloid.

Apparently, this species is encouraged by the recent deluge. Lots more under the Douglas Fir. The fruiting has spread throughout most of the area (which is loaded with buried/decomposed cones) under this tree.

With sufficient magnification, the caps are seen to be variably densely hairy. Possibly the rain has washed off or matted down some of the hairs. I mention this because some reports for this species list the cap as smooth. Also, the mature caps are radially lined (faintly but distinctly striate). But the most interesting thing is that the gills appear to be free… as opposed to having merely seceded.

I studied only specimens found growing directly from the DF cones.

Thanks Debbie;

all very helpful. I have a few additional photos of this one. I’ll check to see if there’s one which shows the gills. Also, I think there may be more of the mushrooms underneath my Douglas Fir. Hopefully the torrential rain we’re currently getting has not completely dissolved all of them. (Imagine that… a mushroomer complaining about too much rain!) I’ve got a miniscule amount of Meltzer’s at home, so I can check spores (if I get some)…. That’s what I want for Christmas… Meltzer’s!

were the gills very crowded?

it is hard to see from your photos, but the one gill shot that I can sorta see seems to show gills too widely spaced apart for Baeospora.

Cap for Baeospora should be glabrous, stem coarsely hairy and spores amyloid.

Strobiluris has more widely spaced gills, a minutely granular cap and inamyloid spores.

I should have mentioned

that I did examine this collection, and through the hand lens, the caps were seen to be densely/minutely hairy. I’m not sure if this is a trait of B. myosura.

Actually, I recently photographed what I proposed as B. myosura. I did not bring this collection home. The photos of obs 75588 (currently under discussion) and this other cone fungus do look a lot alike.
