Ramaria abietina                                                                                                              [more]

    Ramaria botrytis (California, Coastal forest, Fall)
Spores (from several collections): 10.5-16 x 4.8-5.7 (6)μ    

    Ramaria botrytoides    (California, Coastal forest, Fall)

    Ramaria celerivirescens  (California, Coastal forest, Fall)   A clampless, FeSO4-positive species with distinct wine-red stipe discoloration.
Spores (avg, several collections): 8-10.5 (12) x 4-5µ 

    Ramaria coulterae (California, Sierra Nevada Spring)  A totally clampless species.
Spores: 9.5-12 x 3-4μ    

    Ramaria cystidiophora v. anisata    (California, Mendocino, Fall)   
Spores: 6.5-9x3.5-4.3µ (relatively small)     Clamped.

    Ramaria flava    (Bulgaria, montane region, Summer) One of the more common European Ramaria.

Ramaria formosa                                                       [more]

Ramaria magnipes                                                                                                                                            [more]

    Ramaria myceliosa (California, Berkeley) A small coral, abundant under Cypress. It appears to be saprobic.
Spores, small: (3.5) 4-5.3 (5.5) x 3-3.3µ

    Ramaria rasilispora v. rasilispora (California, Sierra Nevada, Spring) 

Spores:  9-12x3.13.8µ  with droplets.

Amyloid reaction developing very slowly

Purplish stains can be seen occasionally.

    Ramaria rasilispora v. scatesiana  (California, Sierra Nevada, Spring)  The pale colored version of the species. 
Spores: (9) 10-10.7 (12) x (3.5) 4-4.5 (4.8)μ

Ramaria rasilispora in an advanced age. Many of the Spring Ramaria develop deep into the substrate and by the time they push the duff aside, they are in a fairly mature stage, having reached a considerable size. At that time the coloration becomes pretty dull and it is very difficult to decide in the field, which species they represent. In most cases these are in the R. rasilispora group. Very frequently there are strong vinacious stains, which convey. R. vinosimaculans.

    Ramaria rubricarnata v. verna (California, Sierra Nevada, Spring)

Spores: 9.5-12.2 x 4.1-4.8µ

FeSO4: negative on the context and positive on branch surface. Of taxonomic interest is only the FeSO4 reaction on the context, as most Ramaria show a positive reaction on the surface.

Amyloid: IKI+

    Ramaria rubiginosa   (California, Coastal forest and Sierra Nevada, Fall)    A clampless red-staining species, very, very similar in appearance to R. sanguinea...
Spores: 8-10.5x4-5µ 

    Ramaria rubrievanescens (California, Sierra Nevada, Spring)   I have the hardest time developing a solid concept of the differences between R. rubripermanens and R. rubrievanescens. There is nothing permanent in the reddish coloration of either one of them. For this collection I have used Petersen & Scate's convention that  the brunescens stipe is an indicator of R. rubrievanescens. They make a point that it doesn't fruit in the Spring, but the argument is based on the existing few collections by Marr & Stuntz. and doesn't sound very convincing. 
Spores: 10-13 x 3.9-4.8µ     The spores of the rubri-evanescens/permanens complex are distinctly shorter and narrower than R. botrytis.

   Ramaria rubripermanens (California, Sierra Nevada Spring) See comments above for R. rubrievanescens.
Apices (young)      Apices (old)  

    Ramaria sandaracina v. chondrobasis (California, Coastal forest, Fall)
Spores: 7.5 - 10 x 3.3 - 4.1µ        (probably the same)

    Ramaria stricta    (California, Coastal forest, Fall)
Spores (avg. several collections) 7.3 - 10 x 4.2 - 5μ

    Ramaria stuntzii (California, Coastal forest, Fall)   
Spores: 7.2-10 x 3.3-4.3µ      The spore ornamentation clearly distinguishes it from R. araiospora.

    Ramaria vinosimaculans (California, Sierra Nevada, Spring)    Spores: 10-14x3.7-4μ

Clamped basidia The other very frequent Ramaria species with massive vinacious stains is the non-clamped autumnal species: R. celerivirescens.
