Iconic Types of
Mushroom Mycelium
Each mushroom species produces a recognizable type of mycelium whose variations fall
within a range of expressions.Within a species,
multitudes of strains can differ dramatically in
their appearance. In culture, mushroom strains
reveal much about the portion of the mushroom
life cycle which is invisible to the mere forager
for wild mushrooms. This range of character-

istics—changes in form and color, rate of

dimensional plane of a nutrient-filled petri dish.

As the mycelium undergoes changes in its
appearance overtime, this progression of transformations defines what is normal and what is
abnormal.The standard medialuse is MaltYeast

Agar (MYA) often fortified with peptone
1. Linear: Linear mycelium is arranged as di-

verging, longitudinal strands. Typically, the
mycelium emanates from the center of the petri
dish as a homogeneously forming mat. Shiitake
(Lentinula edodes) and initially Oyster

growth, flagrance, even volunteer fruitings of
mushrooms in miniature—reveals a wealth of

(Pleurotus ostreatus) mycelia fall in this cat-

information to the cultivator, defining the

linear mycelium, which thickens in time. In

strain's "personality".
Form: Mycelia can be categorized into sevexplanation, these forms are delineated on the

fact, Morel mycelium is so fine that during the
first few days of growth, the mycelium is nearly
invisible, detected only by tilting the petri dish
back and forth so that the fine strands can be
