Observation 97132: Zygomycota Moreau

When: 2012-06-11

Collection location: California, USA [Click for map]

Who: Byrain

No specimen available

This mold was found growing on a rotting Inocybe sp. cap & gills that was forgotten too long in a tackle box which was left in the fridge. The Inocybe sp. was collected from the Eastern Shasta-Trinity National Forest by someone else, but this is not the first time I have seen molds that look like this in one of my tackle boxes, so I’m leaving the location more general.

The hyphae has 1 µ thickened walls and has a dextrinoid reaction, some reacting more strongly then others, the spores are hyaline, the greenish coloring is a camera artifact.

Spore range = 4 – 7 × 2 – 3 (4) µ
Average spore = 5.47 × 2.83 µ
Average Q = 1.97
15 spores measured.

I saw that key and noticed my spores were much smaller, it doesn’t look like the other Spinellus pics I have seen either. Though I’m having a bit difficultly finding in depth literature, anyone know where I should be looking?

The spores are too small for Spinellus. Key is located here:
