Used references: Petersen 1967: M. mucida is strictly lignicolous and seems to typically have pointed, colored tips. M. vernalis is the common terrestrial one associated with algae. It is clavate like the one in this observations, however it is “creamy to fleshy cream or straw-orange when fresh”. Unfortunately I failed to preserve a specimen. There is no mention in this paper of a species that is white, clavate, simple, terrestrial and associated with algae.

I don’t have a copy of the paper

Damon: I last saw it while studying with Trevor Goward. That’s when I wrote the key that appears in the description of Multiclavula. Note: the copy found there is significantly rearranged to emphasize color and substrate over clamp connections and other obscure characters, so I might have “damaged” it inadvertently. Certainly, I would no longer use color as a key character now that I see how often the colored species turn out to actually be essentially white.

Drew: According to the paper, this M. vernalis is supposed to turn more colored with age. I suspect it is only white when young. It is also supposed to be club-shaped, not pointed, but that may well be as variable as everything else(!)

I’ve found Multiclavula growing on a low soil bank that I assume is M. vernalis in northeast Washington state (http://www.flickr.com/...). It has more color than this collection and is composed of a mixture of clavate and more pointed basidiocarps.

Do you have a link to this paper? Online I only found it on JSTOR a partial page.

I was speaking a couple days ago to John Davis, who thought he found vernalis on the west coast

Could well be, was just curious of your reasoning

This is only barely a lichen, far more of a mushroom really, since it doesn’t really produce a proper “thallus”, just hyphae among a pre-existing algal slime. Lichenomphalia, on the other hand, at least in some cases, produces an actual crustose or even squamulose (L. hudsoniana) vegetative thallus. That’s as true a marriage of mycology and lichenology as you get!

Jason,

Okay, I shouldn’t dabble into lichens, I really don’t know much about them…
But, I thought M. vernalis was larger then M. corynoides, and that vernalis has more rounded club-shaped fruiting bodies that are usually darker colored and is only known from the east.

I saw M. mucida recently, which is also darker and was growing on wood…

Hey Noah, so why the sudden insistance that these obs are M. corynoides?

Did you see a paper or a specimen recently? According to my only source, M. corynoides should be lacerate and somewhat flattened at the tips, which this specimen is clearly not. What’s the new info that convinces you otherwise??
