Some mushrooms in the Physalacriaceae Clade

Strange Befellows! From Left: Physalacria inflata, Xerula sp., Flammulina velutipes, Rhodotus palmatus.

Moncalvo et al. (2002) have compiled nuclear large subunit rDNA evidence for nearly 900 mushrooms; they estimate that their study includes one-tenth of the known species of gilled mushrooms. The "Physalacriaceae Clade" is one of 117 clades arranged in their enormous phylogram; I have summarized it and several subordinate clades below.

Molecular research on Flammulina by Hughes et al. (1999) and Methven et al. (2000) is also summarized, and inserted into the Moncalvo at el. Physalacriaceae Clade in gray font.

Physalacriaceae Clade

(The umbrella clade for all of the mushrooms below.)

Potential Resulting Taxonomy

* Rhizomarasmius pyrrhocephalus (Marasmius pyrrhocephalus)

* Gloiocephala: Current concept not informative; polyphyletic genus.

* Oudesmansiella = Xerula, at least in part

* Armillaria: Current concept (see Armillaria genus page) confirmed in part. Armillaria matsutake, for example, not included in phylogram; determined to belong in Tricholomatoid Clade as Tricholoma matsutake.
