Identificaciones de maricel-patino

on conifer, probably Eastern White Pine

pores rounded to slightly angular, 7-8 pores per mm.

spores hyaline, “lunate” or crescent shaped, usually with 2 oil droplets, 2.8-3.5 x 1-1.3µm
Me: 3 x 1.2µm

clamps present, dimitic, the last photo shows what I think are "rosette crystals" mentioned in the description in Miettinen and Larsson "Sidera, a new genus in Hymenochaetales with poroid
and hydnoid species" Mycol Progress (2011) 10:131–141

This crust fungus was in patches um to a centimeter across. As their center, these fungi were somewhat yellow, but. became progressively more purple as you moved out. They appeared slightly hairy (particularly at their edges), and were on the underside of decaying hardwood.
At first, I was unsure that this was a fungus, but then I realized that the hairs are very similar to cultured fungi. After looking in Mushrooms of the Gulf Coast States (Bessette et al. 2019), I realized this was most likely a crust fungus. As such, I then Googled "Florida purple crust fungi," finding the species Phlebiopsis crassa. The description of this fungus, including the hair, purple color, fall collection time, and location (decaying wood) match this specimen. The only macroscopic difference was the small size of this fungus, about a third of the smallest size reported on mushrooomexpert.com, but I attributed this to the drier conditions before collection.I was unable to find any similar Phlebiopsis species, so I concluded this specimen was Phlebiopsis crassa.
