Chocolate candies in custard cups?

Among all the "normal" logs lying on the dunes and the shoreline, one has been colonized by hundreds of tiny bird's nest fungi.

Section of the log. I count 49 nests. Maybe I should have written, "thousands of bird's nest fungi". It's a long log.

The spore cases (peridioles) look more like candies than like eggs. Chocolate candies in pretty little custard cups.

A couple of nests with a couple of escaped spore cases. The rain will wash them away to reproduce in a new site.

Another, almost empty now, with two older nests, disintegrating.

This family of fungi goes by the tongue-twisting name of Nidulariaceae, from the Latin "nidulus", a nest.
The color of the peridioles is characteristic of the genera: Cyathus has black peridioles, Nidularia and Nidula have brown peridioles, Mycocalia has yellow- to red-brown peridioles, and Crucibulum has black peridioles that are surrounded by a whitish membrane called the tunica, which makes them appear white. (Wikipedia)
I looked back through my photos; all but one of the bird's nest fungi I've found have had brown peridioles. The one exception had white peridioles; this was in 2016, on a log on Tyee Spit that I've searched every year since, looking for more, but never seeing any.

Entre todos los troncos "normales" que se encuentran a lo largo de la playa y cubriendo las dunas, uno ha sido invadido por cientos (mejor dicho, miles) de honguitos "nido de pájaro", 
  1. Una sección del tronco. Cuento 49 "niditos" en este sector.
  2. Los sacos llenos de esporas, llamados peridiolos, se parecen (creo) más a golosinas que a huevos. Chocolatitos en una tacita de flan. Aquí hay dos nidos, y con dos peridiolos que ya escaparon. Se los llevará la lluvia para que broten en un sitio nuevo.
  3. Otro nido entero, y dos que ya descargaron sus peridiolos.
Esta familia lleva el nombre de Nidulariaceae, derivado del Latín; "nidulus", nido.
El color de los peridiolos es característico de los géneros: Cyathus tiene peridiolos negros, Nidularia y Nidula tienen peridiolos marrones, Mycocalia tiene peridiolos de color amarillo a rojo marrón, y Crucibulum tiene peridiolos negros que están rodeados por una membrana blanquecina denominada túnica, que los hace parecer blancos. (Wikipedia)
Buscando entre todas mis fotos, veo que en todos los niditos que he visto, aparte de uno, los peridiolos han sido cafés (marrones). El único blanco lo encontré en 2016, en un tronco en Tyee Spit; este tronco lo he examinado cada año desde entonces, sin haber visto ni un solo hongo nido.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
