chorioactis geaster (11. 251)

Appearing only in parts of Texas (recognised as the official state fungi since 2021), Oklahoma and Japan, this leathery star-shaped (usually seven-pointed) flower-like mushroom is delighting mycologists, professionals and amateurs alike. Nothing quite so uncommon, the Lone Star State mushroom also nicknamed the Devil’s Cigar as it is reported

to produce an audible hiss (quite a rare ability at least for the human range of hearing) before unfurling from a clylindrical shape to release spores, but after the thaw, we’ve been noticing quite a few winter funguses distinct from the autumnal ones that we are most accustomed to encountering,
like this formation of hair ice (Haareis) that we thought at first were patches of frost but is a phenomena that occurs when weather conditions are just right, damp and humid and just at the freezing point when ice forms on the substate of a specific kind of mould (Exidiopsis effusa, not identified as the catalyst until 2015) growing on dead wood. The resulting strands and curls, however, are not formed on this fungus but rather extruded, expressed in the shape of ephemeral fine hairs before they sublimate away, though a still unknown mechanism and chemistry.
